Description

Resource allocation method and related device
Technical Field
The present application relates to the field of communications technologies, and in particular, to a resource allocation method and a related device.
Background
Currently, the transmission between terminal devices may be referred to as a Sidelink (SL) transmission. The current side-link communication resource schedule includes physical side-link control channel (PSCCH) resources and physical side-link shared channel (PHYSICAL SIDELINK SHARED CHANNEL, PSSCH) resources in units of subchannels within each slot. Wherein the PSCCH resource is used to carry first stage side uplink control information (sidelink control information, SCI). The PSSCH resource is used to carry the second stage SCI.
A positioning function is introduced in the current side-link communication system, and a dedicated resource pool is defined for transmitting positioning reference signals. The resource pool defines only PSCCH resources and positioning reference signal resources, i.e. only PSCCH channel transmissions and positioning reference signal transmissions are supported. And PSSCH resources are not defined, i.e., PSSCH transmission is not supported. Therefore, how to configure PSCCH resources is a considerable problem.
Disclosure of Invention
The application provides a resource allocation method and a related device, which are used for realizing the allocation of first control channel resources through first allocation information. The flexible configuration of the frequency domain information of the first control channel resource, the first format of the SCI carried on the first control channel resource, and/or the function of the SCI carried on the first control channel resource is realized.
The first aspect of the present application provides a resource allocation method, including:
The terminal equipment receives first configuration information, wherein the first configuration information is used for configuring first control channel resources, and the first configuration information comprises at least one of the following: frequency domain information of the first control channel resource, or first information, the first information being used to indicate a first format of SCI carried on the first control channel resource, and/or a function of SCI carried on the first control channel resource; the terminal device transmits the SCI on the first control channel resource. Further, optionally, before the terminal device sends the SCI on the first control channel resource, the terminal device determines the first control channel resource according to the first configuration information. Optionally, the SCI carried on the first control channel resource is in the first format, and/or the SCI carried on the first control channel resource is the function indicated by the first information.
In the above technical solution, the configuration of the first control channel resource is implemented through the first configuration information. And the first configuration information includes at least one of: frequency domain information of the first control channel resource, or first information. The first information is used to indicate a first format of SCI carried on the first control channel resource and/or to indicate a function of SCI carried on the first control channel resource. Thereby realizing the flexible configuration of the frequency domain information of the first control channel resource, the first format of SCI carried on the first control channel resource, and/or the function of SCI carried on the first control channel resource. Therefore, the frequency domain information of each control channel resource, the format of SCI carried on each control channel resource, and/or the function of SCI carried on each control channel resource can be flexibly configured in the positioning resource pool. Rather than control channel resources, only support transmission of the first stage SCI and fixed frequency domain bandwidth. In other words, the frequency domain bandwidth occupied by the control channel resources can be independently configured to adapt the transmission of SCI of the corresponding format and/or function.
Further, in one aspect, the first configuration information includes frequency domain information that may be the first control channel resources. The side-link communication system can independently configure corresponding frequency domain information for the first control channel resource according to actual requirements. The method is beneficial to improving the spectrum efficiency and the multiuser multiplexing capacity. On the other hand, the configuration information of the first control channel resource may include first information. The first information is used to indicate a first format of SCI carried on the first control channel resource and/or a function of SCI carried on the first control channel resource. Therefore, the terminal device does not need to blindly detect SCI of multiple formats and/or multiple functions on the first control channel resource, but detects SCI of the first format and/or corresponding function on the first control channel resource according to the configuration information of the first control channel resource. And the complexity of blind detection of the terminal equipment is avoided, so that the blind detection overhead of the terminal equipment is reduced.
The second aspect of the present application provides a resource allocation method, including:
The communication device determines first configuration information, the first configuration information being for configuring the first control channel resource, the first configuration information comprising at least one of: frequency domain information of the first control channel resource, or first information, the first information being used to indicate a first format of SCI carried on the first control channel resource, and/or a function of SCI carried on the first control channel resource; the communication device transmits the first configuration information to the terminal device.
In the above technical solution, the communication device implements the configuration of the first control channel resource through the first configuration information. And the first configuration information includes at least one of: frequency domain information of the first control channel resource, or first information. The first information is used to indicate a first format of SCI carried on the first control channel resource and/or to indicate a function of SCI carried on the first control channel resource. Thereby enabling flexible configuration of frequency domain information of the first control channel resource, the first format of SCI carried on the first control channel resource, and/or a function for indicating SCI carried on the first control channel resource. Therefore, the frequency domain information of each control channel resource, the format of SCI carried on each control channel resource, and/or the function of SCI carried on each control channel resource can be flexibly configured in the positioning resource pool. Rather than control channel resources, only support transmission of the first stage SCI and fixed frequency domain bandwidth. In other words, the frequency domain bandwidth occupied by the control channel resources can be independently configured to adapt the transmission of SCI of the corresponding format and/or function.
Based on the first aspect or the second aspect, in one possible implementation manner, the frequency domain information of the first control channel resource includes at least one of the following: the frequency domain bandwidth occupied by the first control channel resource or the initial frequency point occupied by the first control channel resource. In the implementation manner, the occupied frequency domain bandwidth and/or the initial frequency point of the first control channel resource are flexibly configured. I.e. flexibly configuring the size of the bandwidth occupied by the first control channel resources. In one aspect, the communication device independently configures a frequency domain bandwidth and a starting frequency point occupied by the first control channel resource, thereby facilitating adapting transmission of SCI of a corresponding format and/or function. Thereby enabling the transmission of SCIs supporting different formats and/or functions in the positioning resource pool. On the other hand, the method is favorable for independently configuring corresponding frequency domain bandwidth and starting frequency points for the first control channel resources according to actual requirements. The method is beneficial to improving the spectrum efficiency and the multiuser multiplexing capacity. For example, the first control channel resource carries the first level SCI, and then the frequency domain bandwidth occupied by the first control channel resource may be smaller.
Based on the first aspect or the second aspect, in a possible implementation manner, the frequency domain bandwidth includes: the number of Resource Elements (REs), the number of Resource Blocks (RBs), or the number of subchannels; the starting frequency point includes a starting RE, a starting RB, or a starting sub-channel. In this implementation, some possible implementations of frequency domain bandwidth are shown, facilitating implementation of the scheme. The application is applicable to other forms of frequency domain bandwidths and other forms of starting frequency points, and is not particularly limited.
Based on the first aspect or the second aspect, in a possible implementation manner, the first information includes format information and/or function information of SCI carried on the first control channel resource; or the first information is first indication information, where the first indication information is used to indicate a first format of SCI carried on the first control channel resource and/or a function of SCI carried on the first control channel resource. Two implementations of the first information are shown, enriching the implementation of the scheme.
Based on the first aspect or the second aspect, in one possible implementation manner, the first format includes a first-level SCI format, a second-level SCI format, or a first-level SCI format and a second-level SCI format. In this implementation, several possible SCI formats are shown, facilitating implementation of the scheme. The application is applicable to other SCI formats, and is not particularly limited.
Based on the first aspect or the second aspect, in a possible implementation manner, the function of the SCI includes at least one of the following: user collaboration, resource indication, or reservation. Thereby realizing the corresponding function through SCI. The user collaboration function includes a resource request function between users, and/or a resource allocation function between users.
Based on the first aspect, in one possible implementation manner, the method further includes: the terminal equipment receives second configuration information, wherein the second configuration information is used for configuring second control channel resources, and the second configuration information comprises at least one of the following: frequency domain information of the second control channel resource, or second information for indicating a second format of SCI carried on the second control channel resource, and/or a function for indicating SCI carried on the second control channel resource; the terminal device transmits the SCI on the second control channel resource. Further, optionally, before the terminal device sends the SCI on the second control channel resource, the terminal device determines the second control channel resource according to the second configuration information. Optionally, the SCI carried on the second control channel resource is in the second format, and/or the SCI carried on the second control channel resource is a function indicated by the second information. From this implementation, the communication device configures the first control channel resource and the second control channel resource with independent configuration information, respectively. Thereby enabling configuration specific or dedicated to different control channel resources. For example, different control channel resources may be configured with frequency domain information independently, thereby facilitating adaptation to different SCI formats, and/or SCI with different functions, and further facilitating improved spectrum utilization. As another example, different control channel resources may carry SCIs of different formats and/or SCIs of different functions, thereby supporting transmission of SCIs of different formats and/or transmission of SCIs of different functions in a pool of positioning resources.
Based on the second aspect, in one possible implementation manner, the method further includes: the communication device determines second configuration information; the second configuration information is used for configuring second control channel resources, and the second configuration information comprises at least one of the following: frequency domain information of the second control channel resource, or second information for indicating a second format of SCI carried on the second control channel resource, and/or a function for indicating SCI carried on the second control channel resource; the communication device transmits the second configuration information to the terminal device. It can be seen that the communication device configures the first control channel resource and the second control channel resource through independent configuration information, respectively. Thereby enabling configuration specific or dedicated to different control channel resources.
Based on the first aspect or the second aspect, in one possible implementation manner, the frequency domain information of the first control channel resource includes at least one of the following: the frequency domain bandwidth occupied by the first control channel resource or the initial frequency point occupied by the first control channel resource; the frequency domain information of the second control channel resource includes at least one of: the frequency domain bandwidth occupied by the second control channel resource or the initial frequency point occupied by the second control channel resource; the frequency domain bandwidth occupied by the first control channel resource is the same as or different from the frequency domain bandwidth occupied by the second control channel resource, and/or the starting frequency point occupied by the first control channel resource is the same as or different from the starting frequency point occupied by the second control channel resource. In the implementation manner, the frequency domain bandwidth and/or the initial frequency point occupied by the second control channel resource are flexibly configured. Further, the frequency domain bandwidth occupied by the first control channel resource is the same as or different from the frequency domain bandwidth occupied by the second control channel resource, and/or the starting frequency point occupied by the first control channel resource is the same as or different from the starting frequency point occupied by the second control channel resource. And the frequency domain bandwidths and/or the initial frequency points of different control channel resources are independently configured. Thereby facilitating the adaptation of different control channel resources to different SCI formats and/or SCIs of different functions, and further facilitating the improvement of spectrum utilization.
Based on the first aspect or the second aspect, in a possible implementation manner, the second information includes format information and/or function information of SCI carried on the second control channel resource; or the second information is second indication information, where the second indication information is used to indicate a second format of SCI carried on the second control channel resource and/or is used to indicate a function of SCI carried on the second control channel resource. Two implementations of the second information are shown, enriching the implementation of the scheme.
Based on the first aspect or the second aspect, in a possible implementation manner, the first format is the same as or different from the second format; the SCI carried on the first control channel resource may or may not function the same as the SCI carried on the second control channel resource. Thereby realizing independent configuration of SCIs carrying different SCI formats and/or different functions on different control channel resources. The transmission of SCI supporting different formats and/or different functions in the positioning resource pool is realized.
Based on the first aspect or the second aspect, in one possible implementation manner, the frequency domain bandwidth occupied by the first control channel resource is larger than the bandwidth of the sub-channel. Thereby being convenient for independently configuring the frequency domain bandwidth occupied by the first control channel resources according to the actual requirements. The frequency domain bandwidth may be greater than or equal to the bandwidth of the sub-channel to enable the first control channel resource to carry SCI containing more bits. The transmission of SCI supporting different formats and/or different functions in the positioning resource pool is realized.
Based on the first aspect or the second aspect, in one possible implementation manner, the frequency domain bandwidth occupied by the second control channel resource is larger than the bandwidth of the sub-channel. Thereby being convenient for independently configuring the frequency domain bandwidth occupied by the first control channel resources according to the actual requirements.
Based on the first aspect or the second aspect, in a possible implementation manner, the terminal device sends the SCI on the first control channel resource, including: the terminal device transmits SCI in a first format on a first control channel resource. In this implementation, the first configuration information includes first information. The terminal device therefore determines the first format based on the first information and transmits the SCI in the first format on the first control channel resources. Thereby facilitating monitoring of SCI of the first format on the first control channel resources by other terminal devices in the side-link communication system. Blind detection of SCI of multiple formats on the first control channel resource is not required. And the detection overhead is reduced, and the endurance capacity of the terminal equipment is improved.
Based on the first aspect or the second aspect, in one possible implementation manner, the first configuration information further includes third information, where the third information is used to indicate whether the terminal device monitors SCI carried on the first control channel resource; or the first configuration information further includes a bit map, where bits in the bit map correspond to one or more control channel resources, and one or more bits in the bit map are used to indicate whether the terminal device monitors SCI carried on the control channel resources corresponding to the one or more bits, where the first control channel resources belong to control channel resources in the side uplink communication system. Therefore, invalid monitoring of the terminal equipment on the first control channel resource is avoided, and overhead caused by monitoring is avoided. For example, in the case where the number of positioning reference signal resources is smaller than the number of control channel resources in the positioning resource pool, SCI is not transmitted on the first control channel resource. The terminal device determines from the third information that it is not necessary to monitor the SCI on the first control channel resources. Thereby reducing the monitoring overhead of the terminal equipment. It should be noted that, this implementation manner may also be a separate aspect, and not depend on the first aspect or the second aspect.
Based on the first aspect or the second aspect, in a possible implementation manner, the second configuration information includes fourth information, where the fourth information is used to indicate whether the terminal device monitors SCI carried on the second control channel resource. Therefore, invalid monitoring of the terminal equipment on the second control channel resource is avoided, and overhead caused by monitoring is avoided.
Based on the first aspect or the second aspect, in a possible implementation manner, the first configuration information is included in the resource pool configuration information; the resource pool configuration information comprises a bit bitmap, wherein bits in the bit bitmap correspond to control channel resources in the side uplink communication system, one or more bits in the bit bitmap are used for indicating whether terminal equipment monitors SCIs carried on the control channel resources corresponding to the one or more bits, and the first control channel resources belong to the control channel resources in the side uplink communication system. In this implementation, the first configuration information is included in the resource pool configuration information; the resource pool configuration information comprises a bit map by which it is indicated whether the terminal device monitors the SCI on the respective control channel resources. Therefore, invalid monitoring of the terminal equipment on the control channel resource which does not send SCI is avoided, and the cost caused by monitoring is avoided. And the cruising ability of the terminal equipment is improved.
Based on the first aspect or the second aspect, in one possible implementation manner, the first configuration information further includes an identifier of a positioning reference signal resource corresponding to the first control channel resource, and/or an identifier of a positioning reference signal resource set corresponding to the first control channel resource. Thereby establishing an association relationship between the first control channel resource and the positioning reference signal resource and/or the positioning reference signal resource set. Is beneficial to guaranteeing the function of specific resources. For example, the terminal device may send an SCI through a first control channel resource, where the SCI is used to reserve a positioning reference signal resource and/or a positioning reference signal resource set corresponding to the first control channel resource. Thereby facilitating the terminal device to find out the appropriate positioning reference signal resource and facilitating the lateral link positioning. For example, when the terminal device has a high-precision positioning requirement, the terminal device may transmit the SCI through the corresponding control channel resource, so as to reserve a positioning reference signal resource with a larger bandwidth through the SCI. Thereby meeting the high-precision positioning requirement of the terminal equipment.
Based on the first aspect or the second aspect, in one possible implementation manner, the first configuration information further includes parameter information of a positioning reference signal resource corresponding to the first control channel resource, where the parameter information includes at least one of the following: the comb size, frequency domain offset, or occupied starting time domain symbols of the positioning reference signal resources. And indicating the positioning reference signal resource corresponding to the first control channel resource through the parameter information of the positioning reference signal resource.
Based on the first aspect or the second aspect, in a possible implementation manner, the second configuration information further includes an identifier of a positioning reference signal resource corresponding to the second control channel resource, and/or an identifier of a positioning reference signal resource set corresponding to the second control channel resource.

Is beneficial to guaranteeing the function of specific resources.
Based on the first aspect or the second aspect, in one possible implementation manner, the second configuration information further includes parameter information of a positioning reference signal resource corresponding to the second control channel resource, where the parameter information includes at least one of the following: the comb size, frequency domain offset, or occupied starting time domain symbol of the positioning reference signal resource. And indicating the positioning reference signal resource corresponding to the second control channel resource through the parameter information of the positioning reference signal resource.
Based on the first aspect or the second aspect, in a possible implementation manner, the first configuration information is included in the resource pool configuration information; the resource pool configuration information also includes common configuration information between the first control channel resources and the second control channel resources.

In particular, the network device may be an access network device for a third generation partnership project (3rd generation partnership project,3GPP) related cellular system. Such as a 4G communication system, or a 5G communication system.

It should be noted that in different systems, a CU (or CU-CP and CU-UP), a DU or RU may have different names, but those skilled in the art will understand the meaning. For example, in ORAN systems, a CU may also be referred to as an open centralized unit (open centralized unit, O-CU) or an open CU, a DU may also be referred to as an open distributed unit (open distributed unit, O-DU), a centralized unit-control plane (centralized unit control plane, CU-CP) may also be referred to as an O-CU-CP or an open CU-CP, a centralized unit-user plane (centralized unit user plane, CU-UP) may also be referred to as an O-CU-UP or an open CU-UP, and an RU may also be referred to as an open radio unit (O-RU), as the application is not limited in this respect. Any unit of CU, CU-CP, CU-UP, DU and RU in the present application may be implemented by a software module, a hardware module, or a combination of software and hardware modules.
Alternatively, for network elements in the ORAN system, each network element may implement the protocol layer functions as shown in table 1 below.
TABLE 1
The architecture of CUs and DUs of the access network device is presented below. The access network device comprises at least one CU and at least one DU. Optionally, the access network device further comprises at least one RU.
The following description will take an example in which the access network device includes a CU and a DU. The CUs have part of the functionality of the core network and may include CUs-CPs and CUs-UPs. CUs and DUs may be configured according to the protocol layer functions of the wireless network they implement. For example, a CU is configured to implement the functions of a packet data convergence layer protocol (PACKET DATA convergence protocol, PDCP) layer and above (e.g., the RRC layer and/or SDAP layer), a DU is configured to implement the functions of a PDCP layer below (e.g., the RLC layer, the MAC layer, and/or the Physical (PHY) layer), and a CU is configured to implement the functions of a PDCP layer above (e.g., the RRC layer and/or SDAP layer), a DU is configured to implement the functions of a PDCP layer below (e.g., the RLC layer, the MAC layer, and/or the PHY layer, etc.).
When a CU includes a CU-CP for implementing the control plane functions of the CU and a CU-UP for implementing the user plane functions of the CU. For example, when the CU is configured to implement functions of the PDCP layer, the RRC layer, and the SDAP layer, the CU-CP is used to implement functions of the RRC layer and control plane functions of the PDCP layer, and the CU-UP is used to implement functions of the SDAP layer and user plane functions of the PDCP layer.
The CU-CP may interact with network elements in the core network for implementing control plane functions. The network elements in the core network for implementing the control plane functions may be access and mobility function network elements, such as access and mobility functions (ACCESS AND mobility management function, AMF) in a 5G system. The access and mobility function network element is used for being responsible for mobility management in a mobile network, such as location update of terminal equipment, registration network of terminal equipment, handover of terminal equipment, etc. The CU-UP may interact with network elements in the core network for implementing user plane functions. Network elements in the core network for implementing user plane functions, e.g. user functions (User Plane Function, UPF) in the 5G system, are responsible for forwarding and receiving data in the terminal device.
The configuration of the CU and the DU above is merely an example, and the CU and the DU may have functions configured as needed. For example, a CU or DU may be configured to have functions of more protocol layers, or may be configured to have partial processing functions of protocol layers. For example, a part of functions of the RLC layer and functions of protocol layers above the RLC layer are set at CU, and the remaining functions of the RLC layer and functions of protocol layers below the RLC layer are set at DU. For another example, the functionality of a CU or DU may be partitioned by traffic type or other system requirements. For example, according to the time delay division, a function whose processing time is required to satisfy the smaller time delay requirement is set in the DU, and a function whose processing time is not required to satisfy the time delay requirement is set in the CU.
The DU and RU may cooperate to collectively implement the functionality of the PHY layer. One DU may be connected to one or more RUs. The functions possessed by DUs and RUs may be configured in a variety of ways depending on the design. For example, a DU is configured to implement baseband functionality and an RU is configured to implement medium radio frequency functionality. As another example, the DU is configured to implement higher layer functions in the PHY layer, and the RU is configured to implement lower layer functions in the PHY layer or to implement the lower layer functions and the radio frequency functions. The higher layer functions in the physical layer may include a portion of the functions of the physical layer that are closer to the MAC layer, and the lower layer functions in the physical layer may include another portion of the functions of the physical layer that are closer to the medium radio frequency side.
In the present application, the means for realizing the functions of the network device may be the network device, or may be a means capable of supporting the network device to realize the functions. For example, a system on a chip, a hardware circuit, a software module, or a combination of hardware and software modules, the apparatus may be installed in or matched to a network device. For example, the network device may be the device or apparatus shown above, or may be a component (e.g., a chip), a module, or a unit in the device or apparatus shown above, and the application is not limited specifically. In the technical solution provided in the present application, the device for implementing the function of the network device is a network device, and the network device is a base station as an example, which describes the technical solution provided in the present application.
The positioning equipment is used for carrying out positioning calculation and management on the terminal equipment. For example, the locating device may be an LMF.
The communication system suitable for the technical scheme of the application comprises the terminal equipment and the communication equipment. The communication device may be a network device, a terminal device, an RSU or a positioning device, and the present application is not limited specifically.
In order to facilitate understanding of the technical solution of the present application, the following description will be made on the basic concept related to the present application.
1. Resource pool (resource pool): the terminal device may use resources in the side uplink resource pool for data transmission, one resource pool may configure one or more consecutive physical resource blocks (physical resource block, PRBs) (or referred to as Resource Blocks (RBs)) in the frequency domain and one or more slots (slots) in the time domain, where the slots may be consecutive or non-consecutive.
To facilitate understanding of the meaning of the resource pool, an exemplary description of the resource pool in the side link is described below in connection with fig. 5A. Fig. 5A shows a schematic diagram of a plurality of resource pools. A portion of the carrier bandwidth (carrier bandwidth) spectrum for SL may be referred to as a side-row fractional bandwidth, SL BWP, (sidelink bandwidth part) within which multiple resource pools may be defined. For example, three resource pools (resource pool #1, resource pool #2, and resource pool # 3) shown in fig. 5A. Illustratively, one resource pool is configured with a plurality of consecutive RBs in a frequency domain, and a certain number of consecutive RBs may form one sub-channel, and the terminal device may transmit SL data using one or more sub-channels. In other words, the minimum unit granularity at which the terminal device transmits or receives the SL data may be referred to as a subchannel, and the number of RBs in one subchannel may be 10, 12, 15, 20, 25, 50, 75, or 100.
Alternatively, in the side-uplink communication system, the resource pool used for communication may be referred to as a communication resource pool, and the resource pool used for positioning may be referred to as a positioning resource pool.
2. The resource: refers to time-frequency resources in a resource pool. The time domain resource may be represented as a symbol (symbol), a slot (slot), a sub-slot (sub-slot), a mini-slot (mini-slot), a partial slot (partial slot), a subframe (sub-frame), a radio frame (frame), a sensing slot (sensing slot), and the like. The frequency domain resources may be expressed as Resource Elements (REs), resource Blocks (RBs), sub-channels (sub-channels), resource pools (resource pool), bandwidths (bandwidth), bandwidth parts (BWP), carriers (carriers), channels, interlaces (interlaces), and the like.
3. First stage SCI format: also called first stage SCI, supports related functions such as occupation and reservation of positioning reference signal resources. For example, the first stage SCI format may be 36 bits in length. For example, sci-1-A, or sci-1-B. sci-1-A may also be referred to as sci format 1-A, sci-1-B may also be referred to as sci format 1-B, and the application is not particularly limited. Of course, the first stage SCI format may be SCI-1-C, SCI-1-D, and the application is not limited thereto, and more forms of the first stage SCI format may be extended in accordance with actual requirements.
4. Second stage SCI format: also referred to as a second level SCI, for indicating user identification related information, resource allocation information, or some extended functionality, e.g. user collaboration functionality. For example, sci-2-A, or sci-2-B, or sci-2-C. The sci-2-A may be referred to as sci format 2-A, sci-2-B may be referred to as sci format 2-B, and sci-2-C may be referred to as sci format 2-C, but the application is not limited thereto. For example, sci-2-C is mainly used for terminal devices to reserve resources for other terminal devices. Of course, the second-stage SCI format may also be SCI-2-D, or SCI-2-E, and the application is not particularly limited, and more forms of the second-stage SCI format may be specifically extended in accordance with actual requirements.
5. SCI function: comprising at least one of the following: a resource indication or reservation function, or a user cooperation function. The resource indication or reservation function may be understood as a basic function of the SCI, and the user cooperation function may be understood as an extension function of the SCI.
Optionally, the user collaboration function includes a resource request function between users, and/or a resource allocation function between users. The resource request function between users means that the terminal equipment requests other terminal equipment to reserve resources for the terminal equipment, or the terminal equipment receives resource requests of other terminal equipment, wherein the resource requests are used for requesting the terminal equipment to reserve resources for the other terminal equipment. The resource allocation function between users means that the terminal equipment reserves resources for other terminal equipment and informs the other terminal equipment of related information about the reserved resources; or the terminal equipment receives the resource allocation information sent by other terminal equipment, wherein the resource allocation information comprises the related information of the resources reserved by the other terminal equipment for the terminal equipment.
For example, when the function of the SCI is a resource indication or reservation function, the length of the SCI is the first length. For example, the first length may be 36 bits. When the SCI function includes a resource indication or reservation function and a user cooperation function, the SCI has a second length. For example, the second length is 60 bits. The first length and the second length described above are just one example. The first length and the second length may be predetermined values or values calculated based on relevant parameters of the system, and the present application is not limited thereto.
6. PSCCH and PSSCH: according to the Rel-16/Rel-17NR protocol, the scheduling granularity of PSCCH and/or PSSCH is in units of one slot in the time domain and one or more subchannels in succession in the frequency domain.
The UE may send sidelink information on the resource, and may carry PSCCH and PSSCH and signals such as demodulation reference signals (demodulation REFERENCE SIGNAL, DMRS), channel state information reference signals (CHANNEL STATE information REFERENCE SIGNAL, CSI-RS) on one resource. Wherein the PSCCH carries a first-stage SCI, and the PSSCH carries a second-stage SCI and/or data.
Fig. 5B shows a schematic diagram of a transmission structure of PSCCH and PSSCH in an NR system. The PSCCH, PSSCH may be carried on 1 slot, 3 subchannels, where 1 slot includes 14 symbols. As shown in fig. 5C, different users occupy different sub-channels. As shown in fig. 5C, fig. 5C is a schematic diagram of frequency division multiplexing of different users according to the present application. From fig. 5C, it can be seen that ue#1 occupies subchannel 6 and subchannel 5, and ue#2 occupies subchannel 2 and subchannel 1.
A positioning function is introduced in the side-uplink communication system, defining a dedicated resource pool for transmitting positioning reference signals. This resource pool may also be referred to as a positioning resource pool. The positioning resource pool defines only PSCCH resources and positioning reference signal resources, i.e. only PSCCH channel transmissions and positioning reference signal transmissions are supported. And PSSCH resources are not defined, i.e., PSSCH transmission is not supported. As shown in fig. 5D, a user may occupy the corresponding PSCCH resources and send SCI on the PSCCH resources. Thereby realizing the reservation of the corresponding positioning reference signal resource. However, as can be seen from the above description, currently, in the communication resource pool, only the first-stage SCI is supported in the PSCCH resource pool, and the second-stage SCI cannot be supported. Therefore, how to configure PSCCH resources is a considerable problem. The application provides a corresponding technical scheme, and particularly refers to the related description of the specific embodiment.
In the present application, the bandwidth and the starting frequency point of the sub-channel may be configured in the configuration information of the resource pool. The resource pool is a resource pool where positioning reference signal resources are located in the side uplink communication system or a resource pool where control channel resources are located. For example, the bandwidth of the sub-channel is 1MHz (megahertz), 2MHz, or the like. Or the bandwidth and the starting frequency point of the sub-channel in the present document can also be determined according to the bandwidth of the resource pool and the number of the positioning reference signal resources, or other parameters, and the specific parameters are not limited in the present document. For example, the bandwidth of the resource pool is 20MHz, and the resource pool includes eight positioning reference signal resources. Each positioning reference signal resource corresponds to one sub-channel, so that the bandwidth of each sub-channel is 2.5MHz, and a total of eight sub-channels, sub-channel 0 to sub-channel 7, are known. Start of sub-channel 0 to sub-channel 7 respectively the frequency points are {0,2.5,5,7.5,10,12.5,15,17.5} MHz.
In the present application, optionally, the control channel resource may be a side-link control channel resource. The positioning reference signal resource may be a side-uplink positioning reference signal resource.
In the present application, optionally, the first control channel resource may be understood as one control channel resource. Thus, the configuration of the first control channel resource may be understood as a configuration of the control channel resource, specifically comprising at least one of the following: frequency domain information of the control channel resource, a format of SCI carried on the control channel resource, or a function of SCI carried on the control channel resource. Or the first control channel resource may also be understood as a class of control channel resources, which may comprise one or more control channel resources. For example, the first control channel resources may be referred to as first type control channel resources. The configuration of the first control channel resources may comprise a configuration of a first type of control channel resources or a configuration of one or more control channel resources. For example, the configuration of the first control channel resources includes at least one of: frequency domain information of the first type of control channel resources, a format of SCI carried on the first type of control channel resources, or a function of SCI carried on the first type of control channel resources. For the second control channel resource, the second control channel resource may be understood as one control channel resource, and thus, the configuration of the second control channel resource may be understood as the configuration of the control channel resource. Or the second control channel resource may also be understood as another type of control channel resource, which may comprise one or more control channel resources. For example, the second control channel resources may be referred to as second type control channel resources. The configuration of the second control channel resources may comprise a configuration of a second type of control channel resources or a configuration of one or more control channel resources.
The technical scheme of the application is described below in connection with specific embodiments.
FIG. 6 is a schematic diagram of an embodiment of a resource allocation method according to an embodiment of the present application. Referring to fig. 6, the method includes:
601. The communication device transmits the first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the communication device.
The first configuration information includes information for configuring the first control channel resources. The first configuration information includes at least one of: frequency domain information of the first control channel resource, or first information. The first information is used to indicate a first format of SCI carried on the first control channel resource and/or a function of SCI carried on the first control channel resource.
It should be understood that the first configuration information is configuration information of first control channel resources for configuring the first control channel resources. Optionally, the first configuration information is independent of the resource pool configuration information; or the first configuration information is contained in the resource pool configuration information; or the first configuration information includes configuration information of control channel resources in the resource pool, and the configuration information of the control channel resources is included in the resource pool configuration information. The resource pool refers to a resource pool where the control channel resource or the positioning reference signal resource is located.
The frequency domain information of the first control channel resource is described below.
The frequency domain information of the first control channel includes at least one of: the frequency domain bandwidth occupied by the first control channel resource or the initial frequency point occupied by the first control channel resource.
The frequency domain bandwidth occupied by the first control channel resource characterizes the bandwidth size occupied by the first control channel resource on the frequency domain. For example, the frequency domain bandwidth occupied by the first control channel resource includes the number of REs occupied by the first control channel resource, the number of RBs occupied, or the number of subchannels occupied. Wherein one subchannel includes one or more RBs. Or the frequency domain information of the first control channel resource comprises a first proportion value, wherein the first proportion value is the proportion between the sub-channel occupied by the first control channel resource and the bandwidth of the resource pool, so that the frequency domain bandwidth occupied by the first control channel resource is represented by the first proportion value. Or the frequency domain bandwidth occupied by the first control channel resource may be indicated in other manners, which is not limited in the present application. The technical scheme of the application is mainly described below by taking the number of sub-channels occupied by the first control channel resource as an example. For example, as shown in fig. 7, the first control channel resource is a PSCCH1 resource, and the PSCCH1 resource occupies two sub-channels.
Optionally, the frequency domain bandwidth occupied by the first control channel resource is smaller than, equal to, or greater than the bandwidth of the sub-channel. For example, as shown in fig. 8, the first control channel resource is a PSCCH3 resource, and the PSCCH3 resource occupies a part of the bandwidth in the sub-channel 4 in the frequency domain, that is, the PSCCH3 resource occupies a smaller frequency domain bandwidth than the sub-channel. As another example, as shown in fig. 7, the first control channel resource is a PSCCH3 resource, and the PSCCH3 resource occupies a subchannel 4 in the frequency domain, that is, the PSCCH3 resource occupies a frequency domain bandwidth equal to the bandwidth of the subchannel. As another example, as shown in fig. 7, the first control channel resource is a PSCCH1 resource, where the PSCCH1 resource occupies a frequency domain of sub-channels 0 and 1, i.e., the PSCCH1 resource occupies a frequency domain bandwidth that is greater than the bandwidth of the sub-channels.
Alternatively, the frequency domain bandwidth occupied by the first control channel resource may be determined based on an implementation of the network device, or the network device may select from a plurality of candidate frequency domain bandwidths. Alternatively, the plurality of candidate frequency domain bandwidths may be candidate frequency domain bandwidths preset in the communication resource pool.
The initial frequency point occupied by the first control channel resource comprises: the starting RE, the starting RB, the starting subchannel, an Absolute Radio Frequency Channel Number (ARFCN), an absolute frequency point value, an offset value of the starting RE with respect to a fixed frequency, or an offset value of the starting RB with respect to the fixed frequency, or may be a starting frequency point indicating the occupation of the first control channel resource in other manners, which is not limited in the present application.
Optionally, the starting frequency point of the first control channel resource may also be a default starting frequency point, which is not limited in the present application. For example, the default starting frequency point is a starting RB in the default subchannel or a starting RE in the default subchannel. In this implementation, the frequency domain information of the first control channel resource may not include the starting frequency point of the first control channel resource.
Optionally, in the side-uplink communication system, each subchannel includes one control channel resource. Therefore, the control channel resources do not need to independently configure the initial frequency points, and the initial frequency points occupied by the control channel resources can be determined according to corresponding rules. Therefore, in this implementation, the frequency domain information of the first control channel resource may not include the starting frequency point occupied by the first control channel resource.
Optionally, the first format includes a first level SCI format, a second level SCI format, or both. For the first level SCI format and the second level SCI format, refer to the relevant description in the technical terminology above.
Alternatively, the function of SCI carried on the first control channel resource may be specifically described with reference to the foregoing technical terminology.
In a possible implementation, the first information includes format information and/or function information of SCI carried on the first control channel resource. The first configuration information includes format information of SCI carried on the first control channel resource. As can be seen from the following first configuration information, the format information of SCI carried on the first control channel resource is cell SupportedSCIFormat, and cell SupportedSCIFormat is used for indicating the first format, which is SCI-1-a, SCI-1-B, or SCI-2-a. The first configuration information includes functional information of SCI carried on the first control channel resource. As can be seen from the following first configuration information, when the function information is cell SupportedSCIInfo and the value of cell SupportedSCIInfo is 00, it means that the SCI carried on the first control channel resource has a basic function. I.e. a resource indication or reservation function. When the value of the cell SupportedSCIInfo is 01, it indicates that the SCI carried on the first control channel resource has a basic function and an extended function. I.e. a resource indication or reservation function and a user cooperation function.
In another possible implementation manner, the first information is first indication information. The first indication information is used for indicating a first format of SCI carried on the first control channel resource and/or a function of SCI carried on the first control channel resource. For example, the first indication information is two bits, and when the value of the first indication information is 01, the first format is the first-stage SCI format. When the value of the first indication information is 10, the first format is the second-level SCI format. When the value of the first indication information is 11, the first format is a first-level SCI format and a second-level SCI format.
One possible format of the first configuration information is described below, in particular as follows:
For example, the first configuration information includes starting frequency point information of the first control channel resource occupation. The starting frequency point information is used for indicating a starting frequency point occupied by the first control channel resource. The cell StartSubChannel is configured for indicating a starting sub-channel occupied by the first control channel resource as in the cell StartSubChannel in the first configuration information. It should be understood that the name of the cell StartSubChannel and the manner of indication of the cell StartSubChannel (i.e., INTERGER (0,, M)) are examples, and the application is not limited thereto.
For example, the first configuration information includes bandwidth information of the first control channel resource. The bandwidth information is used to indicate a frequency domain bandwidth occupied by the first control channel resource. For example, the cell sl-FreqResourcePSSCH-r18 in the first configuration information is used to indicate the frequency domain bandwidth occupied by the first control channel resource. It should be understood that the name of the cell sl-FreqResourcePSSCH-r18 and the manner of indication of the cell sl-FreqResourcePSSCH-r18 (i.e., ENMERATED { n10, n12, n15, n20, n25, n30, n40,, }) are examples, and the application is not limited thereto.
For example, the first configuration information includes format information of SCI carried on the first control channel resource. The format information is used to indicate a first format of SCI carried on the first control channel resource. For example, as in the cell SupportedSCIFormat in the first configuration information described above, the cell SupportedSCIFormat is used to indicate the first format of SCI carried on the first control channel resource. For example, the first format may be sci-1-A, sci-1-B, or sci-2-A. It should be appreciated that the name of cell SupportedSCIFormat and the manner in which cell SupportedSCIFormat is indicated (i.e., { sci-1-A, sci-1-B, sci-2-A }) are examples and the application is not limited thereto.
The first control channel resource may be understood as a specific control channel resource, where the first control channel resource carries an SCI, and the format of the SCI is the first format. Or the first control channel resource may be understood as a class of control channel resources comprising one or more control channel resources. In the one or more control channel resources, each control channel resource carries one SCI, and the format of the SCI carried on each control channel resource is a first format.
Another format of the first configuration information is shown below. The method comprises the following steps:
the first configuration information includes starting frequency point information of first control channel resource occupation. For the initial frequency point information, please refer to the related description, and the description is omitted here. The first configuration information includes format information of SCI carried on the first control channel resource. For this format information, please refer to the related description above, and the description is omitted here.
The first configuration information includes bandwidth information of the first control channel resource. The bandwidth information is used to indicate a frequency domain bandwidth occupied by the first control channel resource. For example, as in the cell LenSubChannel in the first configuration information, the cell LenSubChannel is used to indicate the number of subchannels occupied by the first control channel resource. It should be understood that the name of the cell LenSubChannel and the manner of indication of the cell LenSubChannel (i.e., INTERGER (0,,, K)) are examples, and the application is not limited thereto.
Still another possible implementation of the first configuration information is shown below. The method comprises the following steps:
the first configuration information includes starting frequency point information of first control channel resource occupation. For the initial frequency point information, please refer to the related description, and the description is omitted here. The first configuration information includes format information of SCI carried on the first control channel resource. For this format information, please refer to the related description above, and the description is omitted here.
The first configuration information includes SCI information of SCI carried by the first control channel resource. The SCI information is used to indicate the function of the SCI carried by the first control channel resource. For example, the SCI function is the first function and/or the second function. The first function is used for resource indication or reservation, which may also be referred to as resource indication or reservation function. If the function of the SCI is the first function, the length of the SCI is the first length. For example, the first length is 36 bits. The second function is for cooperation between users for indicating or requesting positioning reference signal resources. The second function may also be referred to as a user collaboration function. If the function of the SCI includes a first function and a second function, the SCI has a length of a second length. For example, the second length is 60 bits. For example, the cell SupportedSCIInfo in the first configuration information is used to indicate the SCI function carried on the first control channel resource. For example, when the value of the cell SupportedSCIInfo is 00, it indicates that the SCI carried on the first control channel resource has a basic function. I.e. a resource indication or reservation function. When the value of the cell SupportedSCIInfo is 01, it indicates that the SCI carried on the first control channel resource has a basic function and an extended function. I.e. a resource indication or reservation function and a user cooperation function.
The first control channel resource may be understood as a specific control channel resource, where the first control channel resource carries an SCI, and when the value of the cell SupportedSCIInfo is 00, the function of the SCI is a resource indication or reservation function; when the value of cell SupportedSCIInfo is 01, the SCI function is a resource indication or reservation function and a user cooperation function. Or the first control channel resource may be understood as a class of control channel resources comprising one or more control channel resources. The function of the SCI carried on each control channel resource in the one or more control channel resources is dependent on the value of the cell SupportedSCIInfo.
Still another possible implementation of the first configuration information is shown below. The method comprises the following steps:
The first configuration information includes starting frequency point information of first control channel resource occupation. For the initial frequency point information, please refer to the related description, and the description is omitted here. The first configuration information includes bandwidth information of the first control channel resource. For bandwidth information, please refer to the related description above, and the description is omitted here. The first configuration information includes format information and function information of SCI carried by the first control channel resource. For format information and functional information, refer to the related description.
The first control channel resource is understood to be a specific control channel resource, on which an SCI is carried, the SCI being in a first format, and the function of the SCI being dependent on the value of the cell SupportedSCIInfo. Or the first control channel resource may be understood as a class of control channel resources comprising one or more control channel resources. In the one or more control channel resources, each control channel resource carries an SCI, the format of the SCI carried on each control channel resource is a first format, and the function of the SCI carried on each control channel resource depends on the value of the cell SupportedSCIInfo.
Optionally, the first configuration information further includes an index of the first control channel resource for distinguishing from other control channel resources. For example, the cell pscch_config_index is used to indicate the index of the first control channel resource as in the first configuration information described above.
Alternatively, the first configuration information shown above is only one example. For example, "SL-PSCCH-CANDIDATE-Config-r18" may also be referred to as "SL-PSCCH-Resource-Config-r18", and the application is not limited in particular.
In step 601, the communication device may configure the first control channel resource through the first configuration information. Further, the configuration of the first control channel resources includes at least one of: frequency domain information of the first control channel resource, or first information. The method and the device have the advantages of realizing the functions of flexibly configuring the frequency domain information of the first control channel resource, the format of SCI carried on the first control channel resource and/or SCI carried on the first control channel resource. Therefore, the frequency domain information of the control channel resource, the format of the SCI carried on the control channel resource, and/or the function of the SCI carried on the control channel resource can be flexibly configured in the positioning resource pool. Rather than control channel resources, only support transmission of the first stage SCI and fixed frequency domain bandwidth.
Further, in one aspect, the configuration of the first control channel resources includes frequency domain information that may be the first control channel resources. The communication device can independently configure corresponding frequency domain information for the first control channel resource according to actual requirements. The method is beneficial to improving the spectrum efficiency and the multiuser multiplexing capacity. For example, the first stage SCI may be carried on a first control channel resource, and the communication device may allocate a smaller frequency domain bandwidth for the first control channel resource.
If the configuration mode of the communication resource pool is referred, each control channel resource needs to support SCIs with multiple formats, and the frequency domain bandwidth occupied by each control channel resource is configured according to the SCI format with the longest length. The number of control channel resources that can be simultaneously supported by the positioning resource pool is reduced, and the multiuser multiplexing capacity is affected. Moreover, the control channel resources support SCIs of multiple SCI formats, and the terminal device needs to perform blind detection on SCIs of multiple SCI formats on the control channel resources. The blind detection complexity is increased, the perception overhead of the terminal equipment is increased, and the endurance is reduced. In the technical solution of the present application, the configuration information of the first control channel resource may include first information. The first information is used to indicate a first format of SCI carried on the first control channel resource and/or to indicate a function of SCI carried on the first control channel resource. Therefore, the terminal device does not need to blindly detect SCI of multiple formats or multiple functions on the first control channel resource, but detects SCI of the first format and/or corresponding function on the first control channel resource according to the configuration information of the first control channel resource. And the complexity of blind detection of the terminal equipment is avoided, so that the blind detection overhead of the terminal equipment is reduced.
It should be appreciated that the above illustrates a first format in which the first information is indicative of SCIs carried on the first control channel resources, and an implementation of the functionality of SCIs carried on the first control channel resources. I.e. showing the format and function of the SCI carried on the first control channel resource indicated by a field in the first configuration information. In practical applications, the format and function of SCI carried on the first control channel resource may also be indicated by multiple fields of the first configuration information. The application is not particularly limited. For example, the first information is used to indicate a first format of SCI carried on the first control channel resource, and the first configuration information further includes fifth information used to indicate a function of SCI carried on the first control channel resource.
In one possible implementation, the first configuration information is included in resource pool configuration information. The first configuration information may be understood as dedicated configuration information of the first control channel resources. Still further, optionally, the resource pool configuration information includes control channel resource configuration information of the resource pool, and the first configuration information includes control channel resource configuration information of the resource pool. The resource pool is a resource pool where a control channel resource or a positioning reference signal resource is located. For example, the resource pool may be referred to as a positioning resource pool. The control channel resource configuration information of the resource pool includes dedicated configuration information of respective control channel resources in the side-uplink communication system. Optionally, the control channel resource configuration information of the resource pool may further comprise common configuration information of control channel resources in the side-uplink communication system. For example, in a side-link communication system, the number of time domain symbols occupied by each control channel resource is the same, and the starting time domain symbol occupied by each control channel resource is the same. The common configuration information includes at least one of: the number of time domain symbols occupied by control channel resources, or the starting time domain symbols occupied, in a side-link communication system.
For example, as shown in FIG. 9, the first configuration information includes configuration information in cell SL-PSSCH-CANDIDATE-Config-r16. The cell nr-PSCCH-CANDIDATELIST in the control channel resource configuration information of the resource pool includes a plurality of cells SL-PSSCH-CANDIDATE-Config-r16. I.e. the first configuration information is included in the control channel resource configuration information of the resource pool. The common configuration information for the control channel resources is included in the cells Common Parameters in the control channel resource configuration information for the resource pool.
In another possible implementation manner, the first configuration information further includes at least one of the following: the number of time domain symbols occupied by the first control channel resource, or the starting time domain symbol occupied.
In a possible implementation, the first configuration information further includes third information. The third information is used to indicate whether the terminal device monitors or perceives SCI carried on the first control channel resource.
For example, as shown in FIG. 10, three positioning reference signal resources are included in the positioning Resource pool, namely, side-uplink positioning reference signal resources (sidelink positioning REFERENCE SIGNALS Resource, SL-PRS Resource 1), SL-PRS Resource2, and SL-PRS Resource3, respectively. The positioning resource pool comprises ten control channel resources, namely PSCCH1 resources to PSCCH10 resources. The number of positioning reference signal resources is less than the number of control channel resources. Some of the ten control channel resources are not used for transmitting SCI. For example, PSCCH4 resources are not used on PSCCH10 resources to transmit SCI. The terminal device may not monitor SCI on the portion of the control channel resources. Thereby reducing the overhead of the terminal device.
For example, another possible format of the first configuration information is described below, specifically as follows:
For example, as shown in the first configuration information, the third information is cell Activation/Sensing. The value of the cell Activation/Sensing is "on", which indicates that the terminal device monitors SCI on the first control channel resource. For example, if the value of the cell Activation/Sensing is "off", it indicates that the terminal device does not monitor SCI on the first control channel resource. The terminal device may determine whether to monitor the SCI on the first control channel resource based on the value of the cell Activation/Sensing.
For example, another possible format of the first configuration information is shown below, specifically as follows:
For example, as shown in the first configuration information, the third information is cell Activation/Sensing. The value of the cell Activation/Sensing is "0", which indicates that the terminal device monitors SCI on the first control channel resource. For example, if the value of the cell Activation/Sensing is "1", it means that the terminal device does not monitor SCI on the first control channel resource. The terminal device may determine whether to monitor the SCI on the first control channel resource based on the value of the cell Activation/Sensing.
Alternatively, the name of the action/Sensing cell is merely an example, and may specifically be other names, which is not limited by the present application.
In another possible implementation, the first configuration information further includes a bit map. The bits in the bit map correspond to one or more control channel resources. One or more bits in the bit map are used to indicate whether the terminal device monitors or perceives SCI carried on the control channel resource to which the one or more bits correspond. The first control channel resource belongs to one or more control channel resources.
Optionally, the first control channel resource is a type of control channel resource, the first control channel resource comprising one or more control channel resources. The bits in the bit map correspond to the one or more control channel resources. Optionally, one bit in the bit map corresponds to one of the one or more control channel resources.
For example, another possible format of the first configuration information is shown below, specifically as follows:
As can be seen from the above first configuration information, the first configuration information includes a cell ActivatedSubChannel, and the cell ActivatedSubChannel includes a bit map. One bit in the bit map corresponds to one control channel resource and different bits correspond to different control channel resources. For example, if the value of the bit is "0", the method is used for indicating that the terminal device does not monitor SCI on the control channel resource corresponding to the bit. If the value of the bit is "1", the method is used for indicating the terminal equipment to monitor SCI on the control channel resource corresponding to the bit. For another example, if the bit has a value of "1", the method is used to instruct the terminal device not to monitor SCI on the control channel resource corresponding to the bit. If the value of the bit is "0", the bit is used for indicating the terminal equipment to monitor SCI on the control channel resource corresponding to the bit.
The first control channel resource is herein described as a first type of control channel resource, and the first type of control channel resource includes one or more control channel resources. Each of the one or more control channel resources occupies a subchannel. As shown in fig. 10, the first type of control channel resources include PSCCH1 resources to PSCCH10 resources. Each of the PSCCH1 resources to PSCCH10 resources occupies a sub-channel. Specifically, PSCCH1 resources occupy subchannel 0, PSCCH h2 resources occupy subchannel 1, and so on, PSCCH10 resources occupy subchannel 9. The first bit in the bit map corresponds to the PSCCH1 resource and is used to indicate whether the terminal device is monitoring SCI on the PSCCH1 resource. The second bit in the bit map corresponds to the PSCCH2 resource and is used to indicate whether the terminal device is monitoring SCI on the PSCCH2 resource. And so on, the tenth bit in the bit map, which corresponds to the PSCCH10 resource, is used to indicate whether the terminal device monitors SCI on the PSCCH10 resource.
Three positioning reference signal resources, SL-PRS Resource1, SL-PRS Resource2 and SL-PRS Resource3, respectively, are included in the positioning Resource pool. The number of positioning reference signal resources is less than the number of control channel resources. Some of the ten control channel resources are not used for transmitting SCI. For example, none of PSCCH1, PSCCH3, PSCCH5, PSCCH7, PSCCH9, and PSCCH10 resources are used to transmit SCI. Thus, the bit map may be 0101010100. Specifically, the expression can be represented as the following table 2:
TABLE 2
It follows that each bit in the bit map is used to indicate whether the terminal device monitors the SCI on the control channel resource to which the bit corresponds.
The first control channel resource may be understood as a specific control channel resource, and it may be determined whether the terminal device monitors the SCI on the first control channel resource through the third information. Or the first control channel resource may be understood as a class of control channel resources comprising one or more control channel resources. It may be determined, in particular, from the bit map whether SCI is monitored on each of the one or more control channel resources.
In yet another possible implementation, the first configuration information is included in the resource pool configuration information. The resource pool configuration information includes a bit map, bits in the bit map corresponding to control channel resources in the side-link communication system. One or more bits in the bit map are used to indicate whether the terminal device monitors or perceives SCI carried on the control channel resource to which the one or more bits correspond. The first control channel resource belongs to a control channel resource in the side-link communication system.
Reference may be made to the above-mentioned related description regarding resource pool configuration information. Optionally, one bit in the bitmap corresponds to one control channel resource, and different bits correspond to different control channel resources. For example, if the value of the bit is "0", the method is used for indicating that the terminal device does not monitor SCI on the control channel resource corresponding to the bit. If the value of the bit is "1", the method is used for indicating the terminal equipment to monitor SCI on the control channel resource corresponding to the bit. For another example, if the bit has a value of "1", the method is used to instruct the terminal device not to monitor SCI on the control channel resource corresponding to the bit. If the value of the bit is "0", the bit is used for indicating the terminal equipment to monitor SCI on the control channel resource corresponding to the bit.
Optionally, the resource pool configuration information includes configuration information of control channel resources of the resource pool. The bitmap is located in configuration information of control channel resources of the resource pool. Fig. 11 is a diagram illustrating a possible format of configuration information of control channel resources of a resource pool according to an embodiment of the present application. As shown in fig. 11, the configuration information of the control channel resources of the resource pool includes a cell ActivatedSubChannel, where the cell ActivatedSubChannel includes a bit map, and a bit in the bit map corresponds to one control channel resource, and is described herein by taking as an example that each control channel resource occupies one subchannel. The relevant examples of the bitmaps can be referred to in the foregoing description of table 2, and will not be repeated here. It follows that each bit in the bit map is used to indicate whether the terminal device monitors the SCI on the control channel resource to which the bit corresponds.
Optionally, the first configuration information further includes an identifier of a positioning reference signal resource corresponding to the first control channel resource, and/or an identifier of a positioning reference signal resource set corresponding to the first control channel resource. For example, one possible format of the first configuration information is described below, specifically as follows:
As can be seen from the above format, the first configuration information includes a cell SL-PRS-ResourceSet, where the cell SL-PRS-ResourceSet is used to indicate an identity of a positioning reference signal resource set corresponding to the first control channel resource.
It should be noted that, alternatively, the names of the cells SL-PRS-resource are just an example, and may be other names specifically, which is not limited by the present application.
For another example, the format of the first configuration information is specifically as follows:
As can be seen from the above format, the first configuration information includes a cell SL-PRS-Resource for indicating an identity of a positioning reference signal Resource corresponding to the first control channel Resource.
Optionally, the first configuration information further includes parameter information of a positioning reference signal resource corresponding to the first control channel resource. For example, the parameter information includes at least one of: a comb size (comb size), a frequency domain offset (offset), or a start symbol (start symbol) of the positioning reference signal resource. The comb size may also be referred to as the comb fraction. The comb size refers to the difference of indexes of any two adjacent subcarriers in subcarriers occupied by the positioning reference signal resource on one time domain symbol, or the number of subcarriers of the interval between any two adjacent subcarriers in subcarriers occupied by the positioning reference signal resource on one time domain symbol plus one. For example, the first configuration information may be expressed as:
As can be seen from the above formats, the first configuration information includes a cell SL-PRS-ResourceOffset, and the cell SL-PRS-ResourceOffset is used to indicate a frequency domain offset of a positioning reference signal resource corresponding to the first control channel resource. That is, in this implementation, the positioning reference signal resource corresponding to the first control channel resource is indicated by the parameter information of the positioning reference signal resource. The format of the first configuration information is merely an example, and the actual first configuration information may further include a comb size of the positioning reference signal resource corresponding to the first control channel resource, or a start time domain symbol, etc., which is not limited in the present application. For example, the first configuration information may be expressed as:
As can be seen from the above format, the first configuration information includes the comb information of the reference signal resource, and is carried by the cell SL-PRS-ResourceCombSize, which indicates the comb size of the positioning reference signal resource corresponding to the first control channel resource. The configuration information of other reference signals is not specifically exemplified.
Optionally, the first control channel resource is used for sending an SCI, and the SCI is used for reserving a positioning reference signal resource or a set of positioning reference signal resources corresponding to the first control channel resource. Thereby realizing the establishment of the association relation between the control channel resource and the positioning reference signal resource or the positioning reference signal resource set. The terminal equipment reserves the positioning reference signal resource or the positioning reference signal resource set corresponding to the first control channel resource through the first control channel resource conveniently.
In the present application, on the other hand, an association is established between the control channel resource and the positioning reference signal resource or the positioning reference signal resource set, and an association is established between the control channel resource and the SCI format or the SCI function. Advantageously, reserving part of the positioning reference signal resources for certain specific SCI formats or specific SCI functions is achieved. For example, the first format of the SCI carried by the first control channel Resource is SCI-2-E, which is used for inter-user cooperation, while the first control channel Resource is associated with two positioning reference signal resources, SL-PRS Resource1 and SL-PRS Resource2, respectively. In this way, 2 positioning reference signal resources are reserved for cooperation between users, and SL-PRS Resource1 and SL-PRS Resource2 can be used only when the terminal needs to perform the user cooperation function. The terminal equipment cannot use the two positioning reference signal resources when executing other functions, so that the normal operation of the user cooperation function and the availability of the resources can be ensured.
Alternatively, the communication device may be a network device, a terminal device, an RSU or a positioning device, which is not limited by the present application. The procedure by which the communication device configures the first control channel resources is described below in connection with the morphology of the communication device.
Implementation 1: the communication equipment is network equipment, and the network equipment sends first configuration information to the terminal equipment through a Uu interface. The first configuration information is carried in RRC signaling. Optionally, the first configuration information is included in the resource pool configuration information. Optionally, the resource pool configuration information includes control channel resource configuration information of the resource pool, and the first configuration information is included in the control channel resource configuration information of the resource pool.
Implementation 2: the communication device is a second terminal device, and the terminal device in the step 601 is referred to as a first terminal device. The second terminal device sends the first configuration information to the first terminal device through the PC5 interface. The first configuration information is carried in RRC signaling.
Implementation 3: the communication device is an RSU that transmits the first configuration information to the terminal device via a side-uplink positioning protocol (sidelink positioning protocol, SLPP).
Implementation 4: the communication device is a positioning device. The positioning device sends first configuration information to the terminal device. The first configuration information is carried in an LTE positioning protocol (LTE positioning protocol, LPP) message.
602. And the terminal equipment determines a first control channel resource according to the first configuration information.
Specifically, the first configuration information includes frequency domain information of the first control channel resource. And the terminal equipment determines the frequency domain resources occupied by the first control channel resources on the frequency domain according to the frequency domain information. For example, as shown in fig. 7, the first control channel resource is a PSCCH1 resource. The frequency domain information of the first control channel resource comprises two sub-channels occupied by the PSCCH1 resource, and a starting sub-channel occupied by the PSCCH1 resource is sub-channel 0. Thus, the terminal device may determine that the first control channel resource occupies sub-channel 0 and sub-channel 1 in the frequency domain.
Optionally, the first configuration information includes control channel resource configuration information of the resource pool. The control channel resource configuration information of the resource pool includes common configuration information of control channel resources in the side-uplink communication system. For example, the common configuration information includes the number of time domain symbols occupied by the control channel resources and the starting time domain symbol occupied. For example, the common configuration information includes three time domain symbols occupied by the control channel resources, and the starting time domain symbol occupied by the control channel resources is time domain symbol 0. Thus, the terminal device may determine that the first control channel resource occupies time domain symbol 0 to time domain symbol 2 in the time domain.
It should be appreciated that the above step 602 is optional.
603. The terminal device transmits the SCI on the first control channel resource.
Optionally, the first configuration information includes first information, where the first information is used to indicate a first format of SCI carried on the first control channel resource and/or a function of SCI carried on the first control channel resource. The format of the SCI in step 603 is the first format, and/or the function of the SCI in step 603 is the function indicated by the first information. For example, the step 603 specifically includes: the terminal device transmits SCI in a first format on a first control channel resource. In one possible implementation, the first format is sci-1-A, and the terminal device may then send sci-1-A on the first control channel resource. Optionally, the sci-1-A is used for resource indication or reservation. In yet another possible implementation, the first format is sci-2-A, and the terminal device may then send sci-2-A on the first control channel resource. Optionally, sci-2-A is used for resource indication or reservation, and inter-user collaboration. In yet another possible implementation, the first format is sci-1-A and sci-2-A, and the terminal device may then transmit sci-1-A and sci-2-A on the first control channel resource.
Optionally, the first configuration information further includes an identification of a positioning reference signal resource corresponding to the first control channel resource. For example, as shown in fig. 10, the first control channel resource is a PSCCH1 resource, and the first configuration information includes an identifier of a positioning reference signal resource 1 corresponding to the PSCCH1 resource. The terminal device transmits SCI on PSCCH1 resources. The SCI is used for reserving the positioning reference signal resource 1 corresponding to the PSCCH1 resource.
Optionally, the first configuration information further includes an identification of a positioning reference signal resource set corresponding to the first control channel resource. For example, as shown in fig. 12, the first control channel resource is a PSCCH1 resource, and the first configuration information includes an identifier of a positioning reference signal resource set 1 corresponding to the PSCCH1 resource. The terminal device transmits SCI on PSCCH1 resources. The SCI is used for reserving a positioning reference signal resource set 1 corresponding to the PSCCH1 resource.
Optionally, the embodiment shown in fig. 6 further includes steps 604 to 606. There is no fixed execution sequence between step 604 to step 606 and step 601 to step 603. Steps 601 to 603 may be performed first, and steps 604 to 606 may be performed later; or steps 604 to 606 may be performed first, and steps 601 to 606 may be performed later; or step 601 to step 603 and step 604 to step 606 are performed simultaneously according to circumstances, and the present application is not limited thereto.
604. The communication device transmits the second configuration information to the terminal device. Correspondingly, the terminal device receives the second configuration information from the communication device.
The second configuration information is used to configure the second control channel resources. The second configuration information includes at least one of: frequency domain information of the second control channel resource, or second information. The second information is used to indicate a second format of SCI carried on the second control channel resource and/or to indicate a function of SCI carried on the second control channel resource.
It should be understood that the second configuration information is configuration information of the second control channel resources for configuring the second control channel resources. Optionally, the second configuration information is independent of the resource pool configuration information; or the second configuration information is contained in the resource pool configuration information; or the second configuration information is included in the control channel resource configuration information of the resource pool, and the control channel resource configuration information is included in the resource pool configuration information. The resource pool refers to a resource pool where the control channel resource or the positioning reference signal resource is located.
The frequency domain information of the second control channel resource includes at least one of: the frequency domain bandwidth occupied by the second control channel resource or the initial frequency point occupied by the second control channel resource.
The frequency domain bandwidth occupied by the second control channel resource characterizes the bandwidth size occupied by the second control channel resource on the frequency domain. For example, the frequency domain bandwidth occupied by the second control channel resource includes the number of REs occupied by the second control channel resource, the number of RBs occupied, or the number of subchannels occupied. Or the frequency domain information of the second control channel resource includes a second scale value. The second ratio value is the ratio between the sub-channel occupied by the second control channel resource and the bandwidth of the resource pool. And therefore, the frequency domain bandwidth occupied by the second control channel resource is represented by the second proportion value. Or the frequency domain bandwidth occupied by the second control channel resource may be indicated in other manners, which is not limited in the present application. The technical scheme of the application is mainly described by taking the number of sub-channels occupied by the second control channel as an example and taking the frequency domain bandwidth occupied by the second control channel resource as an example. For example, as shown in fig. 7, the second control channel resource is a PSCCH3 resource. One subchannel occupied by PSCCH3 resources.
Optionally, the frequency domain bandwidth occupied by the second control channel resource is equal to the bandwidth of the sub-channel.
Optionally, the second control channel resources occupy a frequency domain bandwidth that is greater than the bandwidth of the sub-channels.
Optionally, the specific determination manner of the frequency domain bandwidth occupied by the second control channel resource may be referred to in the foregoing description of the frequency domain bandwidth occupied by the first control channel resource.
The starting frequency point occupied by the second control channel resource comprises: the starting RE, the starting RB, the starting subchannel, the ARFCN, the absolute frequency point value, the offset value of the starting RE with respect to the fixed frequency, or the offset value of the starting RB with respect to the fixed frequency occupied by the second control channel resource, or may be another starting frequency point indicating the second control channel resource occupation, which is not limited in the present application.
Optionally, the starting frequency point of the second control channel resource may also be a default starting frequency point, which is not limited in the present application. For example, the default starting frequency point is a starting RB in the default subchannel or a starting RE in the default subchannel. In this implementation, the frequency domain information of the first control channel resource may not include the starting frequency point of the first control channel resource.
Optionally, in the side-uplink communication system, each sub-channel includes a control channel resource, so the control channel resource does not independently configure the start frequency point. In this implementation, the frequency domain information of the second control channel resource may not include a starting frequency point occupied by the second control channel resource.
In a possible implementation, the second information includes format information and/or function information of SCI carried on the second control channel resource. In this implementation, the second information is similar to the first information described above, and reference may be made to the description related to the first information described above.
In another possible implementation manner, the second information is second indication information, and the second indication information is similar to the first indication information, and specific reference may be made to the description related to the first indication information.
Optionally, the second format includes a first level SCI format, a second level SCI format, or both. For the first level SCI format and the second level SCI format, refer to the relevant description in the technical terminology above.
The format of the second configuration information may refer to the format of the first configuration information, which is not described herein.
Alternatively, the first configuration information and the second configuration information may be included in the same signaling or included in different signaling, which is not limited in the present application.
Optionally, the frequency domain bandwidth occupied by the first control channel resource is the same as or different from the frequency domain bandwidth occupied by the second control channel resource.
For example, as shown in fig. 7, the first control channel resource is a PSCCH1 resource and the second control channel resource is a PSCCH3 resource. The PSCCH1 resource occupies two sub-channels and the PSCCH3 resource occupies one sub-channel. Thus, the frequency domain bandwidth occupied by PSCCH1 resources is not the same as the frequency domain bandwidth occupied by PSCCH3 resources. As can be seen from fig. 7, PSCCH1 resources and PSCCH2 resources occupy a larger bandwidth, respectively. Thus, the PSCCH1 resource and the PSCCH2 resource can each carry SCI with a greater number of bits. And the PSCCH3 resource, the PSCCH4 resource and the PSCCH5 resource occupy smaller frequency domain bandwidths respectively and can carry SCI with smaller bit numbers respectively. For example, both PSCCH1 resources and PSCCH2 resources may carry SCIs in the second level SCI format. The PSCCH3 resources to PSCCH5 resources may each carry SCI in the first level SCI format. Alternatively, SCI carried on PSCCH1 and PSCCH2 resources respectively have more functionality. SCI carried on PSCCH1 and PSCCH2 resources, respectively, are used for resource indication or reservation, and collaboration between users, for example. SCI carried on PSCCH3 resources to PSCCH5 resources, respectively, are used for resource indication or reservation.
For example, as shown in fig. 7, the first control channel resource is a PSCCH3 resource and the second control channel resource is a PSCCH4 resource. The PSCCH1 resource occupies one subchannel and the PSCCH4 resource occupies one subchannel. Thus, the frequency domain bandwidth occupied by PSCCH3 resources is the same as the frequency domain bandwidth occupied by PSCCH4 resources.
Optionally, the starting frequency point occupied by the first control channel resource is the same as or different from the starting frequency point occupied by the second control channel.
For example, as shown in fig. 7, the first control channel resource is a PSCCH1 resource and the second control channel resource is a PSCCH3 resource. The initial sub-channel occupied by PSCCH1 resource is sub-channel 0, and the initial sub-channel occupied by PSCCH3 resource is sub-channel 4. It can be seen that the initial subchannel occupied by PSCCH1 resources is not the same as the initial subchannel occupied by PSCCH3 resources.
It should be noted that, if the frequency domain bandwidth occupied by the first control channel resource is the same as the frequency domain bandwidth occupied by the second control channel resource, and the starting frequency point occupied by the first control channel resource is the same as the starting frequency point occupied by the second control channel resource. Then the first control channel resource is the same control channel resource as the second control channel resource. Multiple users may transmit SCI on the same control channel resource in a code division, comb division, or time division manner. Thereby realizing SCI sent by the receiving terminal device by a plurality of users in code division mode. The combing mode means that the bandwidths occupied by the control channel resources used by different users are the same, the occupied time domain symbols are the same, but the frequency domain offsets occupied by the control channel resources used by the users are different.
Optionally, the first format is the same as or different from the second format. For example, as shown in fig. 7, the first control channel resource is a PSCCH1 resource and the second control channel resource is a PSCCH3 resource. SCI in the second level SCI format may be carried on PSCCH1 resources. The PSCCH3 resources may carry SCI in a first level SCI format. According to the technical scheme, SCIs with various formats can be supported to be sent in the positioning resource pool. The configuration information for each control channel resource indicates the format of the SCI carried on that control channel resource. The receiving end device does not need to blindly detect SCI of different formats on the control channel resource, but detects SCI of specific SCI format on the control channel resource according to the configuration information of the control channel resource. Thereby reducing the blind detection overhead of the receiving terminal equipment and improving the cruising ability of the receiving terminal equipment.
Optionally, the SCI carried on the first control channel resource has the same or different functionality as the SCI carried on the second control channel resource. For example, as shown in fig. 7, the first control channel resource PSCCH1 resource and the second control channel resource PSCCH3 resource. SCI that can be carried on PSCCH1 resources is used for resource indication or reservation, and collaboration between users. SCI carried on PSCCH3 resources is used for resource indication or reservation. According to the technical scheme of the application, the SCI with multiple functions is supported to be sent in the positioning resource pool. The configuration information for each control channel resource indicates the function of the SCI carried on that control channel resource. The receiving end device detects SCI of specific function on the control channel resource according to the configuration information of the control channel resource.
Optionally, the first control channel resource and the second control channel resource are two adjacent control channel resources in the frequency domain, and the frequency domain position occupied by the first control channel resource is discontinuous with the frequency domain position occupied by the second control channel resource.
For example, as shown in fig. 8, the first control channel resource is a PSCCH1 resource and the second control channel resource is a PSCCH2 resource. The PSCCH1 resource and the PSCCH2 resource are two control channel resources that are adjacent in the frequency domain. But PSCCH1 resources do not occupy sub-channel 0 and sub-channel 1, but rather occupy portions of the bandwidth corresponding to sub-channel 0 and sub-channel 1, respectively. The PSCCH2 resource does not occupy sub-channel 2 and sub-channel 3, but rather occupies a portion of the bandwidth respectively corresponding to sub-channel 2 and sub-channel 3. Thus, there is a GAP between PSCCH1 resources and PSCCH2 resources.
Optionally, the second configuration information is included in the resource pool configuration information. For the resource pool configuration information, please refer to the related description above, and the detailed description is omitted here. Optionally, the resource pool configuration information includes control channel resource configuration information of the resource pool, and the second configuration information is included in the control channel resource configuration information, for example, as shown in fig. 9, and the second configuration information is included in the control channel resource configuration information of the resource pool.
Alternatively, the communication device may be a network device, a terminal device, an RSU or a positioning device, which is not limited by the present application. The process of the communication device configuring the second control channel resource for the terminal device is similar to the process of the communication device configuring the first control channel resource for the terminal device, and specific reference may be made to the description related to the process of the communication device configuring the first control channel resource for the terminal device, which is not repeated herein.
In this way, in the technical scheme of the application, the communication equipment can configure each control channel resource through independent configuration information. The different control channel resources may configure independent frequency domain resources. For example, the frequency domain bandwidth occupied by the control channel resources may be less than, greater than, or equal to the bandwidth of the subchannels. Different control channel resources may be associated with different SCI formats and/or different control channel resources may carry SCI for different functions. Thereby enabling transmission of SCIs of different formats and/or transmission of SCIs of different functions in the positioning resource pool. The terminal equipment monitors the SCI carried on the control channel resource according to the SCI format associated with the control channel resource and/or the function of the SCI carried on the control channel resource. And the blind detection of terminal equipment on SCIs with different SCI formats or different functions is avoided, so that the blind detection overhead is reduced. Further, the communication device configures the frequency domain bandwidth occupied by each control channel resource through independent configuration information. For control channel resources carrying the first level SCI or SCIs with less functionality, the communication device may allocate less frequency domain bandwidth for the control channel resources. Thereby improving the spectrum efficiency and the multiuser multiplexing capacity.
It should be appreciated that the above illustrates a second format in which the second information is indicative of SCIs carried on the second control channel resources, and an implementation of the functionality of SCIs carried on the second control channel resources. I.e. the format and function of the SCI carried on the second control channel resource is indicated by a field in the second configuration information. In practical applications, the format and function of SCI carried on the second control channel resource may also be indicated by a plurality of fields in the second configuration information. The application is not particularly limited. For example, the second information is used to indicate a second format of SCI carried on the second control channel resource, and the second configuration information further includes sixth information, which is used to indicate a function of SCI carried on the second control channel resource.
In a possible implementation, the second configuration information further includes fourth information. The fourth information is used to indicate whether the terminal device monitors or perceives SCI carried on the second control channel resource. The fourth information is similar to the third information described above, and reference may be made to the description of the third information described above.
In another possible implementation, the second configuration information further includes a bit map, bits in the bit map corresponding to one or more control channel resources. One or more bits in the bit map are used to indicate whether the terminal device monitors or perceives SCI carried on the control channel resource to which the one or more bits correspond. The second control channel resource belongs to the one or more control channel resources. In this implementation, the second control channel resources may be a second type of control channel resources, the second type of control channel resources including one or more control channel resources. Bits in the bit map in the second configuration information correspond to the one or more control channel resources. For this bitmap, please refer to the related description above, and the description is omitted here.
In yet another possible implementation, the second configuration information is included in the resource pool configuration information. The resource pool configuration information includes a bit map. The bits in the bit map correspond to control channel resources in the side-link communication system. One or more bits in the bit map are used to indicate whether the terminal device monitors or perceives SCI carried on the control channel resource to which the one or more bits correspond. For this bitmap, please refer to the related description above, and the description is omitted here.
Optionally, the second configuration information further includes an identifier of a positioning reference signal resource corresponding to the second control channel resource, and/or an identifier of a positioning reference signal resource set corresponding to the second control channel resource. In this implementation, the format of the second configuration information is similar to that of the first configuration information, and reference may be made to the description related to the format of the first configuration information.
Optionally, the second configuration information further includes parameter information of a positioning reference signal resource corresponding to the second control channel resource. For the parameter information about the positioning reference signal resource corresponding to the second control channel resource, please refer to the related description above. The format of the second configuration information is similar to that of the first configuration information, and reference may be made to the description of the format of the first configuration information.
The second control channel resource is used for transmitting an SCI for reserving a corresponding positioning reference signal resource or a corresponding set of positioning reference signal resources for the second control channel resource. Thereby realizing the establishment of the association relation between the control channel resource and the positioning reference signal resource or the positioning reference signal resource set.
For example, as shown in fig. 12, the first control channel resource is a PSCCH1 resource and the second control channel resource is a PSCCH5 resource. PSCCH1 resource associated positioning reference signal resource set 1 and PSCCH5 resource associated positioning reference signal resource set 2. The positioning reference signal resource set 1 occupies a larger bandwidth than the positioning reference signal resource 2, so that higher positioning accuracy can be realized. The frequency domain bandwidth occupied by the PSCCH1 resource is also larger, so that the PSCCH1 resource supports transmission of SCI containing more bits, thereby implementing reservation of a larger bandwidth set of positioning reference signal resources. Thereby realizing high-precision positioning. And the PSCCH5 resources occupy smaller frequency domain bandwidth, and the reservation of the positioning reference signal resources 2 can be realized through the PSCCH3 resources, so that the basic positioning function is ensured. Therefore, when the terminal equipment has high-precision positioning requirement, the terminal equipment can reserve the positioning reference signal resource with larger bandwidth through the control channel resource with larger frequency domain bandwidth. Thereby ensuring the positioning accuracy.
It should be noted that the first configuration information and the second configuration information may be carried in the same cell or may be carried in different cells, and the present application is not limited thereto.
605. And the terminal equipment determines second control channel resources according to the second configuration information.
Step 605 is similar to step 602 described above, and reference is made specifically to the description of step 602 described above.
It should be appreciated that the above step 605 is optional.
606. The terminal device transmits the SCI on the second control channel resource.
Optionally, the second configuration information includes second information, where the second information is used to indicate a second format of SCI carried on the second control channel resource and/or a function of SCI carried on the second control channel resource. The SCI format in step 606 is the second format, and/or the SCI function in step 606 is the second information indicating function. For example, the step 606 specifically includes: the terminal device transmits the SCI in the second format on the second control channel resource. For example, as shown in fig. 12, the second control channel resource is a PSCCH1 resource and the second format is sci-2-a. Thus, the terminal device transmits sci-2-A on PSCCH1 resources. Optionally, sci-2-A is used for resource indication or reservation, and collaboration between users.
Optionally, the second configuration information further includes an identification of a positioning reference signal resource corresponding to the second control channel resource. For example, as shown in fig. 7, the first control channel resource is a PSCCH1 resource and the second control channel resource is a PSCCH5 resource. The frequency domain bandwidth occupied by PSCCH1 resources is greater than the frequency domain bandwidth occupied by PSCCH5 resources, so SCIs containing a greater number of bits can be carried on the PSCCH resources. The first configuration information includes an identification of a positioning reference signal resource 1 corresponding to the PSCCH1 resource. The second configuration information includes an identification of the positioning reference signal resource 2 corresponding to the PSCCH5 resource. The bandwidth of the positioning reference signal resource 1 is larger than the bandwidth of the positioning reference signal resource 2. The terminal device transmits the second level SCI on PSCCH1 resources. Thereby realizing that the terminal equipment reserves the positioning reference signal resource 1 through the second stage SCI. Thereby facilitating high-precision positioning of the terminal equipment. The terminal equipment sends the first-stage SCI on the PSCCH5 resource, thereby realizing that the terminal equipment reserves the positioning reference signal resource 2 through the first-stage SCI, and being beneficial to guaranteeing the basic positioning function of the terminal equipment.
Optionally, the second configuration information further includes an identification of a positioning reference signal resource set corresponding to the second control channel resource. For example, as shown in fig. 12, the first control channel resource is a PSCCH1 resource and the second control channel resource is a PSCCH5 resource. The frequency domain bandwidth occupied by PSCCH1 resources is greater than the frequency domain bandwidth occupied by PSCCH5 resources, so SCIs containing a greater number of bits can be carried on the PSCCH resources. The first configuration information includes an identification of a set of positioning reference signal resources 1 corresponding to PSCCH1 resources. The second configuration information includes an identification of a set of positioning reference signal resources 2 corresponding to PSCCH5 resources. The terminal device transmits the second level SCI on PSCCH1 resources. Thereby realizing that the terminal equipment reserves the positioning reference signal resource set 1 through the second stage SCI. The terminal equipment sends the first-stage SCI on the PSCCH5 resource, thereby realizing that the terminal equipment reserves the positioning reference signal resource set 2 through the first-stage SCI, and being beneficial to guaranteeing the basic positioning function of the terminal equipment.
It should be understood that the terminal device may transmit SCI on the first control channel resource and the second control channel resource simultaneously, or not simultaneously, and the present application is not limited in particular. In other words, the terminal device may transmit the SCI separately or together on the first control channel resource and the second control channel resource, and the present application is not limited thereto.
The embodiment shown in fig. 6 above describes the technical solution of the present application by taking the process of configuring the first control channel resource and the second control channel resource for the terminal device by the communication device as an example. In practical applications, the communication device may configure more control channel resources. Each of the further control channel resources may be configured by the communication device with separate configuration information. Thereby realizing the function of flexibly configuring the frequency domain information of each control channel resource, the format of SCI carried on the control channel resource and/or SCI carried on the control channel resource. The configurations of different control channel resources may be different or the same, and the present application is not limited in particular. It should be understood that the more control channel resources may be understood as more control channel resources, and may also be understood as more types of control channel resources, and the present application is not limited thereto.
In the embodiment of the application, the terminal equipment receives the first configuration information. The first configuration information includes a configuration of first control channel resources. The configuration of the first control channel includes at least one of: frequency domain information of the first control channel resource, or first information. The first information is used to indicate a first format of SCI carried on the first control channel resource and/or to indicate a function of SCI carried on the first control channel resource. The terminal device transmits the SCI on the first control channel resource. Therefore, the technical scheme of the application realizes the configuration of the first control channel resources through the first configuration information. And the configuration of the first control channel includes at least one of: frequency domain information of the first control channel resource, or first information. The first information is used to indicate a first format of SCI carried on the first control channel resource and/or to indicate a function of SCI carried on the first control channel resource. Thereby, flexible configuration of the frequency domain information of the first control channel resource, the first format of the SCI carried on the first control channel resource, and/or a function for indicating the SCI carried on the first control channel resource is achieved. Therefore, the frequency domain information of the control channel resource, the format of the SCI carried on the control channel resource, and/or the function of the SCI carried on the control channel resource can be flexibly configured in the positioning dedicated resource pool. Rather than control channel resources, only support transmission of the first stage SCI and fixed frequency domain bandwidth.
