Description

Technical Field

The present invention relates to communications technologies, and in particular, to a data transmission method, apparatus, device, storage medium, and program product.

Background

In machine type communications (Machine Type Communication, MTC) and internet of things (Internet of Things, IOT), packet data transmission may be employed.

For SDT of downstream service (Mobile Terminated SDT, MT-SDT), the terminal device may trigger the MT-SDT by Paging (Paging) in general. That is, the terminal device enters a random access procedure, such as a four-step random access (4-Step Random Access), after receiving the page and confirming that the MT-SDT is triggered, and starts the MT-SDT upon receiving Message 4 (Message 4, msg 4) or after receiving Message 4.

Since the terminal device needs to go through the processes of sending Message 1 (Message 1, msg 1), receiving Message 2 (Message 2, msg 2) and sending Message 3 (Message 3, msg 3) from paging to receiving Message 4, the whole process is longer, so that the time delay is larger, and how to reduce the time delay of MT-SDT is a problem to be solved.

Detailed Description

All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

It should be noted that the terms "first," "second," and the like in the embodiments of the present application are used for distinguishing between description and not necessarily for indicating or implying any relative importance, or order of description; the term "plurality" refers to more than two items (including two items).

The IoT network may include, for example, an internet of vehicles. The communication modes in the internet of vehicles system are generally called as Vehicle to other devices (V2X, X may represent anything), for example, the V2X may include: vehicle-to-vehicle (Vehicle to Vehicle, V2V) communication, vehicle-to-infrastructure (Vehicle to Infrastructure, V2I) communication, vehicle-to-pedestrian communication (Vehicle to Pedestrian, V2P) or vehicle-to-network (Vehicle to Network, V2N) communication, etc.

The technical scheme provided by the application can be also suitable for future communication systems, such as a sixth generation mobile communication system and the like. The present application is not limited in this regard.

For a clearer description of the present application, the related art to which the present application relates will be first described below.

In the communication between the terminal device and the base station, when the data amount is small (i.e., packet data), the terminal device can transmit and receive data in an Inactive State or an Idle State, without entering a connection State, so that frequent RRC connection establishment and release can be avoided, network signaling overhead is reduced, and power consumption of the terminal device is reduced, wherein the Inactive State may be an active Mode, an active State or a radio resource control (Radio Resource Control, RRC) active State, the Idle State may be an Idle Mode, an Idle State or an RRC Idle State, and the connection State may be a Connected Mode, a Connected State or RRC Connected State.

In the 5g r17 version, packet data transmissions (Small Data Transmission, SDT) can be categorized into random access packet data transmissions (Random Access SDT, abbreviated RA-SDT) and configuration grant packet data transmissions (Configured Grant SDT, abbreviated CG-SDT). The SDT of R17 is generally referred to as Mobile-originated SDT (MO-SDT). For RA-SDT, the terminal device may send data (e.g., message 3) in a random access channel (Random Access Channel, RACH) procedure (or simply random access procedure). For CG-SDT, the terminal device may transmit data in a Configured Grant (CG) uplink, or in a physical uplink shared channel (Physical Uplink Share Channel PUSCH). Whether RA-SDT or CG-SDT, the terminal device is able to make subsequent continued transmissions, retransmissions or receptions.

In the general case of future mobile terminated SDTs (i.e., MT-SDTs) that will be introduced, the terminal device may trigger the MT-SDT via paging. Specifically, the MT-SDT may be triggered by a paging physical downlink control channel (Physical Downlink Control Channel, PDCCH), may be triggered by a wake-up signal/channel, or may be triggered by a paging message.

The PDCCH is used for bearing resource scheduling information allocated to the terminal equipment, and each terminal equipment monitors the PDCCH allocated to the terminal equipment and acquires the resource scheduling information, so that data can be transmitted only on the time domain frequency domain resource indicated by the resource scheduling information.

The paging PDCCH may be a PDCCH corresponding to a Type2-PDCCH common Search Space Set (SSS) and is generally configured by a paging Search Space parameter (Paging Search Space).

The Wake-up Signal/channel may be a Wake-up Signal (WUS) or a paging advance indication (Paging Early Indication, abbreviated PEI, also known as Early Indication of Paging).

The paging message may be carried by a physical downlink shared channel (Physical Downlink Share Channel, PDSCH for short) scheduled by the paging PDCCH. The paging message may be a Layer3 (L3) message, also referred to as an RRC message.

After the MT-SDT is triggered, the terminal equipment firstly enters a random access process and then starts the SDT, and the whole process is longer, so that the transmission delay of packet data is larger.

For four-step random access, the terminal device may start MT-SDT in or after receiving message 4, since the terminal device may confirm that the resource contention is successful or that the contention is resolved in or after receiving message 4. That is, when the terminal device is triggered by paging confirmation MT-SDT, the terminal device initiates a random access procedure and receives an initial transmission of MT-SDT in message 4 or after message 4 (Initial Transmission), and continues to receive subsequent transmissions of MT-SDT (Subsequent Transmission). However, since the terminal device needs to go through the processes of sending the message 1, receiving the message 2 and sending the message 3 from receiving the paging message to receiving the message 4, the whole process is longer, resulting in a larger transmission delay of the packet data.

One possible way is to advance the transmission of the MT-SDT, i.e. start the transmission in message 2, message 2 being a random access response (Random Access Response, RAR). However, the terminal device does not determine whether the contention itself is successful or cannot confirm whether the contention has been resolved when the MT-SDT starts transmission, and it is easy for the MT-SDT to fail.

In order to solve the above problem, for the physical random access channel PRACH (Physical Random Access Channel, abbreviated as PRACH) resource, the terminal device may use a contention-free random access (Contention Free Random Access, CFRA) resource to perform packet data transmission of the uplink service.

Therefore, the embodiment of the application provides a data transmission method, which reduces the time delay of MT-SDT and improves the communication efficiency by configuring CFRA resources to realize the packet data transmission of downlink service.

Among them, CFRA resources can be understood as that a base station allocates specific random access resources to terminal devices, and the base station can identify specific terminal devices through random access preambles (Random Access Preamble) and/or PRACH occasions (opportunities) to achieve communication.

The PRACH is an access channel when the terminal equipment starts to initiate a call, and when the terminal equipment is initially accessed, the terminal equipment can send an RRC connection establishment request message on the PRACH channel according to the information indicated by the base station to establish RRC connection. PRACH is the only way for users to make initial connections, switch, connection re-establishment and resume uplink synchronization.

For easy understanding, an application scenario to which the embodiments of the present application are applicable is described below in conjunction with the example of fig. 1.

The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following specific embodiments may exist alone or in combination with one another, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a flowchart of a data transmission method according to an embodiment of the present application, where the method may be performed by a terminal device, and referring to fig. 2, the method includes the following steps.

S201, acquiring configuration information of CFRA resources.

The configuration information of CFRA resources may be carried by any one of the following information:

(1) Paging messages.

(2) A radio resource control, RRC, release message.

When the configuration information of the CFRA resource is carried by the paging message, the terminal equipment can initiate random access by using the CFRA resource after receiving the paging message, and start receiving MT-SDT in RAR, thereby reducing the time delay of packet data transmission of downlink service.

When the configuration information of the CFRA resource is carried by the RRC release message, the terminal equipment is converted from a connection state to an idle state or an inactive state after receiving the RRC release message, and can initiate random access by using the CFRA resource in the idle state or the inactive state, and start receiving MT-SDT in RAR, so that the delay of packet data transmission of downlink service is reduced.

Alternatively, the configuration information of the CFRA resource may be carried by a resource configuration parameter (Rach-ConfigDedicated) of the dedicated random access channel. In this way, the resource configuration parameters of the dedicated random access channel can be reused, and the signaling overhead can be reduced.

Alternatively, the paging message may contain the resource configuration parameters of the dedicated random access channel. When the paging message contains the resource configuration parameters of the dedicated random access channel, the CFRA resources may be carried by the resource configuration parameters of the dedicated random access channel in the paging message.

Alternatively, the RRC release message may contain the resource configuration parameters of the dedicated random access channel. That is, when the RRC release message contains the resource configuration parameters of the dedicated random access channel, CFRA resources may be carried by the resource configuration parameters of the dedicated random access channel in the RRC release message.

The configuration information of the CFRA resource may include one synchronization signal block list or a plurality of synchronization signal block lists. In general, the synchronization signal block may be represented by a synchronization signal block index.

The configuration information of the CFRA resource may include a random access preamble and/or PRACH occasion. In general, PRACH occasions may be represented by PRACH Mask indexes (PRACH Mask indexes), and random access preambles may be represented by random access preamble indexes (Random Access Preamble Index). In general, one random access preamble within a CFRA resource corresponds to one synchronization signal block. In general, one PRACH occasion within a CFRA resource corresponds to a set of synchronization signal blocks.

The terminal device may select one synchronization signal block and its corresponding random access preamble and/or PRACH occasion as the resources for MT-SDT.

It should be noted that the CFRA resource may be divided into a plurality of parts, each part corresponding to one synchronization signal block, for example, the CFRA resource may be divided into a plurality of random access preambles, each corresponding to one synchronization signal block. Wherein, the synchronization signal block index can be configured by a synchronization signal block resource list (SSB-ResourceList), and the random access preamble can be configured by a parameter random access preamble.

Optionally, the synchronization signal block list has a correspondence with the physical random access channel timing mask index, that is, one synchronization signal block list corresponds to one physical random access channel timing mask index. When one synchronization signal block can be mapped to a plurality of PRACH occasions, the base station can indicate that all the synchronization signal blocks in the synchronization signal block list are mapped to the same or a plurality of PRACH occasions, and the terminal equipment can determine the PRACH occasion indicated by the base station, so that the base station is prevented from excessively blindly detecting the PRACH occasions. Wherein the PRACH occasion may be configured by a PRACH occasion mask index (PRACH Occasion Mask Index).

One CFRA resource set may include a plurality of CFRA resources. The base station may further instruct the terminal device, via the set of CFRA resources, that one CFRA resource may be selected for the resources of the MT-SDT.

Illustratively, the PRACH occasion mask index has 4 bits (bits) corresponding to 16 code points (Codepoints), and the 16 code points include all PRACH occasion indexes, 8 PRACH occasion indexes (1 synchronization signal block may correspond to at most 8 PRACH occasions), all even PRACH occasion indexes, all odd PRACH occasion indexes, and 5 reserved code points, i.e., 16 total, where the PRACH occasion mask index corresponds to a Table (Table) in the meaning visible standard 38.321 of 7.4-1.

S202, transmitting data on the CFRA resources according to the configuration information of the CFRA resources.

After the terminal equipment acquires the CFRA resource, packet data of downlink service can be received on the CFRA resource, so that downlink data transmission between the terminal equipment and the base station is realized.

In this embodiment, the terminal device obtains the configuration information of the CFRA resource sent by the base station, and transmits data on the CFRA resource according to the configuration information, so that the delay of packet data transmission of the downlink service is effectively reduced, and the communication efficiency is improved.

The base station may further define whether CFRA resources are available when configuring CFRA resources for the terminal device, so that the terminal device uses the CFRA resources according to indication information of the base station, which will be described below by way of a second embodiment.

Fig. 3 is a flowchart of another data transmission method provided in the second embodiment of the present application, where the method may be executed by a terminal device, and referring to fig. 3, the method includes the following steps.

S301, acquiring configuration information of CFRA resources.

(1) SIB messages.

(2) Paging messages.

(3) RRC release message.

When the configuration information of the CFRA resource is carried by the SIB message, all terminal devices in an idle state or an inactive state can use the CFRA resource.

When the configuration information of the CFRA resource is carried by the paging message, all terminal devices in an idle state or inactive state can update the configuration information of the CFRA resource and can use the CFRA resource when receiving the paging message. After receiving the paging message, the terminal equipment initiates random access by using the CFRA resource and starts to receive MT-SDT in RAR, thereby reducing the time delay of packet data transmission of downlink service.

When the configuration information of the CFRA resource is carried by the RRC release message, all terminal apparatuses in an idle state or inactive state may update the configuration information of the CFRA resource and may use the CFRA resource when receiving the RRC release message. After receiving the RRC release message, the terminal equipment initiates random access by using the CFRA resource and starts to receive MT-SDT in RAR, thereby reducing the time delay of packet data transmission of downlink service.

Alternatively, the configuration information of the CFRA resource may be carried by a resource configuration parameter of the dedicated random access channel. In this way, the dedicated random access channel resource configuration parameters can be reused, and signaling overhead can be reduced.

Optionally, the configuration information of the CFRA resource may include one or more synchronization signal block lists, where the synchronization signal block list has a correspondence with the physical random access channel occasion mask index. For a specific description that the configuration information of the CFRA resource contains one synchronization signal block column or contains a plurality of synchronization signal block lists, reference may be made to embodiment one.

It should be noted that, when the configuration information of the CFRA resource includes a plurality of synchronization signal block lists, the base station may instruct, through the indication information, the terminal device to select one synchronization signal block bundle and its corresponding CFRA resource as a resource for receiving MT-SDT.

S302, determining whether CFRA resources are available according to the indication information.

The terminal device may also receive indication information sent by the base station, where the indication information is used to indicate whether CFRA resources are available. That is, after the terminal device obtains the configuration information of the CFRA resource, the terminal device cannot use the CFRA resource, and needs to determine whether the CFRA resource is available according to the indication information, and the base station dynamically indicates whether the CFRA resource is available for the terminal device through the indication information, thereby reducing network resource overhead and improving flexibility.

The indication information may be carried by any one of the following information:

(1) A wake-up signal.

(2) PDCCH order.

(3) Paging PDCCH.

(4) Paging messages.

(5) SDT-related PDCCH.

When the indication information is carried by the wake-up signal, the terminal device in the energy-saving mode (Power Saving Mode, PSM) can monitor the wake-up signal, so that the terminal device can be switched from the energy-saving mode to MT-SDT reception, and by using CFRA resources, the power saving of the terminal device is ensured, and the low time delay of the MT-SDT is ensured, wherein the energy-saving mode is a mode in which the terminal device is in extremely low power consumption.

When the indication information is carried by the PDCCH order, the PDCCH order may instruct a certain terminal device to use one CFRA resource by means of terminal device assignment (UE specificity), sharing is avoided, and the terminal device does not need to decode the PDSCH (because the PDCCH order has no scheduling information of the PDSCH), and the terminal device assignment may be, for example: a Cell radio network temporary identity (Cell-Radio Network Temporary Identifier, C-RNTI) scrambles a cyclic redundancy check code (Cyclic Redundancy Check, CRC).

When the indication information is carried by the paging PDCCH, the terminal equipment in Deep Sleep (Deep Sleep) can monitor the wake-up signal, so that the terminal equipment can be switched from Deep Sleep to MT-SDT reception, and by using CFRA resources, the power saving of the terminal equipment is ensured, and the low time delay of the MT-SDT is ensured. The deep sleep is also a state in which the terminal device is in a low power consumption state, but consumes little power compared to the power saving mode, but can wake up faster. The advantage of the indication information carried by the paging PDCCH is that the terminal device can receive the indication information without decoding the PDSCH, but for a Group of terminal devices (UE Group) or a Subgroup of terminal devices (UE Subgroup), a Group of terminal devices share CFRA resources. Generally, a subset of terminal devices is a subset of the group of terminal devices. Generally, a terminal device Group is a Group of terminal devices corresponding to Paging Occasions (POs), which are also called Paging occasions (PO Group), paging groups (Paging Group), or Paging terminal groups (Paging UE Group). Generally, a subset of terminal devices is a subset of the set of terminal devices to which paging occasions correspond.

When the indication information is carried by the paging message, the terminal equipment in deep sleep can monitor the wake-up signal, so that the terminal equipment can be switched from deep sleep to MT-SDT reception, and by using CFRA resources, the power saving of the terminal equipment is ensured, and the low time delay of the MT-SDT is ensured. The advantage of the indication information carried by the paging message is that the information in the paging message can indicate that a certain terminal device uses one CFRA resource, avoiding sharing, but requiring the terminal device to decode PDSCH.

When the indication information is carried by the PDCCH related to the SDT, the PDCCH related to the SDT can instruct a certain terminal device to use a CFRA resource in a mode appointed by the terminal device, so that sharing is avoided, and in the SDT service, the terminal device generally needs to monitor the PDCCH related to the SDT and acquire a usefulness indication without extra power consumption. The manner of the terminal device specification may be, for example: the C-RNTI scrambles the CRC.

Optionally, the PDCCH related to SDT includes a PDCCH corresponding to the search space of SDT, and in general, the terminal device may receive the search space of SDT through a specified manner (such as scrambling the CRC with the C-RNTI), so that a certain terminal device may be instructed to use a CFRA resource, thereby avoiding sharing.

Alternatively, the search space of the SDT may be configured by any one of the following information:

(1) SDT search space parameter (SDT-SearchSpace).

(2) The SDT configures an authorized search space parameter (SDT-CG-SearchSpace).

(3) Search space parameters for MT-SDT.

When the search space of the SDT is configured by the SDT search space parameter or the SDT configuration authorization search space parameter, since these two parameters are existing parameters (for MO-SDT), they can be directly used, reducing signaling overhead. In general, SDT search space parameters may be used to configure a common search space (Common Search Space, CSS) in either RA-SDT or CG-SDT, and SDT configuration authorization search space parameters may be used to configure a terminal device specified search space (UE specific Search Space, USS) in CG-SDT.

The search space of the SDT may also be configured by the search space parameters used by the MT-SDT.

S303, when the CFRA resource is determined to be available, transmitting data on the CFRA resource according to the configuration information of the CFRA resource.

After the terminal equipment acquires the CFRA resource, when the CFRA resource is determined to be available, packet data of downlink service can be received on the CFRA resource, so that downlink data transmission between the terminal equipment and the base station is realized.

In one possible implementation, when the indication information indicates that CFRA resources are available, the CFRA resources are available within a first time window, such that the CFRA resources are valid within the first time window, that is, the CFRA resources may be released in time, reducing CFRA resource overhead.

The first time window includes a window start position and a window length, where the window start position may be an end symbol of a signal or a channel carrying the indication information, or the window start position may be a first symbol of an end slot of the signal or the channel carrying the indication information, and the window length may be configured by a high-layer parameter. So that both the base station and the terminal equipment can agree on the window starting position.

In another possible implementation, when the indication information indicates that the CFRA resource is available, the CFRA resource is available in the running time of the first timer, so that the CFRA resource is valid in the running time of the first timer, that is, the CFRA resource can be released in time, thereby reducing the CFRA resource overhead.

The starting running time of the first timer is at the ending symbol of the signal or the channel carrying the indication information, or the starting running time of the first timer is at the first symbol of the ending time slot of the signal or the channel carrying the indication information, and the running time of the first timer is configured by high-level parameters. So that both the base station and the terminal equipment can agree on the window starting position.

In this embodiment, the terminal device obtains the configuration information of the CFRA resource sent by the base station, and then determines whether the CFRA resource is available according to the indication information sent by the base station, and when it is determined that the CFRA resource is available, the terminal device can transmit data on the CFRA resource according to the configuration information, thereby effectively reducing the delay of packet data transmission of downlink service, reducing network resource overhead, and improving flexibility.

When the terminal device acquires CFRA resources, it may monitor the PDCCH related to SDT at a preset time to acquire transmission resources, and this will be described in the third embodiment.

Alternatively, the first time may be the first symbol of the SDT-related PDCCH after transmission of the PRACH. After the terminal device sends the PRACH on a certain PRACH occasion, it waits for the first symbol (monitoring occasion) of the SDT-related PDCCH after that, and starts to monitor the SDT-related PDCCH at the first moment by using the symbol as the first moment, and it can be understood that the base station also starts to send the SDT-related PDCCH at the first moment by using the symbol as the first moment.

The first symbol of the SDT-related PDCCH may be the first symbol of the earliest CORESET used for carrying the SDT-related PDCCH, and when different CORESETs are associated with different SDT-related PDCCHs, the first symbol of the earliest CORESET is used as the first time, so that the base station and the terminal device reach consensus, and communication efficiency is improved.

Optionally, the terminal device monitors the PDCCH related to the SDT, and may acquire the resource scheduling information carried on the PDCCH, and receive the packet data of the downlink service on the time-frequency domain resource indicated by the resource scheduling information, so as to implement downlink data transmission between the terminal device and the base station.

In this embodiment, after the first time, the terminal device may monitor the PDCCH related to the SDT to realize transmission of packet data of the downlink service, and meanwhile, may achieve the purpose of power saving.
