DETAILED DESCRIPTION

The development of the new generation of wireless communication –5G New Radio (NR) communication –is a part of a continuous mobile broadband evolution process to meet the requirements of increasing network demand. NR will provide greater throughput to allow more users connected at the same time. Other aspects, such as energy consumption, device cost, spectral efficiency, and latency are also important to meeting the needs of various communication scenarios.

As NR emerges in the wireless domain, UEs will be capable of supporting both protocols at the same time. FIG. 1 shows an exemplary schematic diagram of a system architecture for Dual Connectivity (DC) . The current base station (referred to as the first network element 81) in the core network 103 may select a suitable base station for the UE 80 to function as the second network element 82. For example, the suitable based station can be selected by comparing the channel quality of the base station with a predetermined threshold. Both base stations can provide radio resources to the UE 80 for data transmission on the user plane. On the wired interface side, the first network element 81 and the core network 103 establish a control plane interface 104 for the UE 80. The second network element 82 and the core network 103 may establish a user plane interface 105 for the UE 80. An interface 106 (e.g., Xn interface) inter-connects the two network elements. On the wireless interface side, the first and the second network elements (81 and 82) may provide radio resources using the same or different Radio Access Technologies (RATs) . Each of the network element can schedule transmissions with the UE 80 independently. The network element that has a control plane connection to the core network is referred to as the master node (e.g., the first network element 81) , and the network element that has only a user plane connection with the core network is referred to as the secondary node (e.g., the second network element 82) . In some cases, the UE 80 can be connected to more than two nodes, with one node acting as the primary note and the remaining acting as the secondary nodes.

In some embodiments, a UE can support a LTE-NR dual connection (DC) . For example, one of the typical LTE-NR dual connectivity architectures can be set up as follows: the master node is an LTE RAN node (e.g., eNB) and the secondary node is an NR RAN node (e.g., gNB) . The eNB and the gNB are simultaneously connected the Evolved Packet Core (EPC) network (e.g., LTE core network) . The architecture shown in FIG. 1 can also be modified to include various master/secondary node configurations. For example, a NR RAN node can be the master node and the LTE RAN node can be the secondary node. In such case, the core network for the master NR RAN node is a Next Generation Converged Network (NG-CN) .

UE capabilities for the LTE protocol and the NR protocol in LTE-NR DC include two parts: common capabilities of the UE that are applicable to both LTE and NR protocols for single connectivity scenarios, and band combination capabilities of the UE that are relevant for dual connectivity scenarios. When the UE has multiple simultaneous connections with network nodes, the frequency bands used for different network nodes must cooperate with each other regardless of the RAT type (s) used. Here, the term “cooperate” means that the UE can operate in the frequency bands without any conflicts or substantial interference –that is, the frequency bands can co-exist. For example, the 3rd Generation Partnership Project (3GPP) Standards specify a set of band combinations that can cooperate with each other. If frequency band 1 and frequency band 2 are not specified as a valid band combination, the UE cannot use frequency band 1 in communication with node 1 and frequency band 2 in communication with node 2 and the same time.

This patent document describes techniques that can be implemented to transmit downlink information based on pre-configured dedicated resources for data transmission.

In machine to machine (M2M) communication systems, a terminal (or “User Equipment (UE) ” ) energy power may be consumed during an establishment of a radio resource control (RRC) connection process and data transmission and reception in a RRC connected state. For a NarrowBand-Internet of Things (NB-IoT) small main bearing for data transmission, a terminal may be in an RRC connected state for a short time, and the primary power consumption of the terminal may be during a connection establishment procedure (e.g., a physical random-access channel (PRACH) procedure) . Particularly, in an early data transmission (EDT) , small data packets may be transmitted by the PRACH procedure, and a terminal transmitting small data packets may not have to enter an RRC connected state. Accordingly, in some events, power consumption of a terminal transmitting small data packets may primarily be consumed during the PRACH procedure.

In many cases, a PRACH process in a RRC connection establishment process may be based on PRACH resources, where the process may be divided into four steps. A first step may include a first message from a terminal ( “UE” ) to a base station or communication node (or “eNodeB” ) , which may be represented by: Msg1: UE -> eNodeB. A second step may include a random-access response (RAR) message from the base station to the terminal, which may be represented by: Msg2: eNodeB -> UE. A third step may include a first RRC message from the terminal to the base station, which may be represented by: Msg3: UE-> eNodeB. A fourth step may include a second RRC message from the base station to the terminal, which may be represented by: Msg4: eNodeB -> UE.

The third step (Msg3) may include a UE identifier that identifies a terminal, and the fourth step (Msg4) may complete a contention resolution based on the UE identifier, and the PRACH process may end. In a non-EDT scheme, after the contention resolution is complete, the terminal may enter a RRC connected state and start a terminal-specific data transmission. In an EDT scheme, the third step (msg3) may carry/include uplink data, and the fourth step (Msg4) may include the downlink data. A description of contention completion may indicate that the uplink and/or downlink data has been successfully transmitted to a destination. Upon this completion, the terminal may transition into a RRC idle state.

If a terminal is configured with a dedicated uplink resource in an RRC idle mode, such as a pre-configured uplink resource (PUR) , the data transmission/reception may be performed on the PUR, and contention resolution (UE identification) may be completed based on a pre-configured resource transmitted in the second step (Msg2) . This may shorten the PRACH process and improve efficiency (including energy efficiency) of small data transmission.

When pre-configuring an RRC idle mode dedicated resources for a terminal , the following issues may be considered: strategy considerations for downlink data transmission based on pre-configured dedicated resources, a PUR PDCCH common search space (CSS) configuration method; a PUR UE-specific PDCCH search space (PUR-USS) configuration method, coupling processing method for paging and pre-configured dedicated resources, and PUR dedicated resource configuration method with multi-service pattern overlay.

Example Embodiment 1:

FIGS. 2A-E illustrates an exemplary signaling process of downlink data transmission based on pre-configured dedicated resources. Pre-configured dedicated resources (or “pre-configured uplink resources (PUR) may include a dedicated resource location. A base station 230 (or “eNB” ) may notify a core network node (or “MME” ) 240 of a PUR dedicated resource time (or “time domain location” ) during a PUR resource configuration. In response, the MME 240 may send a paging message that may include downlink data to the eNB 230 at the PUR dedicate resource time.

In FIG. 2A, step 201A illustrates that the eNB 230 may transmit an idle mode data transfer status dedicated pre-configuration message to the terminal 220. The message may include pre-configured idle mode data transfer dedicated resources and a terminal-specific PDCCH search space.

Step 202A: the eNB 230 may transmit a RRC connection release message to the UE 220. This RRC connection release message may include a pre-configured PUR resource) . The UE 220 may transition from the last RRC connection status T1A to the RRC idle state T2A upon receiving the RRC connection release message.

Step 203A: the eNB 230 may transmit a message including a time domain location of the dedicated resource (or “PUR timing” ) is notified to the MME 240 using UE-specific signaling. The UE specific signaling may be a UE CONTEXT RELEASE REQUEST or another dedicated message.

Step 204A: The MME 240 may transmit a UE CONTEXT RELEASE COMMAND to the eNB 230 based on receiving the UE CONTEXT RELEASE REQUEST 203A.

Step 205A: The eNB 230 may transmit a UE CONTEXT RELEASE COMPLETE message to the MME 240 indicating that the UE context release request was completed.

Step 206A: The MME 240 may transmit paging and/or downlink data to the eNB. When the core network 240 has downlink data to be transmitted, one of the following information may be sent to the eNB 230 in the time domain location of the PUR: Paging, Paging and data, data and non-access stratum (NAS) identifier of the UE. The NAS identifier of the UE may be an System Architecture Evolution (SAE) Temporary Mobile Subscriber Identity (STMSI) or an identifier of a similar identifiable UE. The paging and/or downlink data may be transmitted at the pre-configured resource time domain location, where the UE 220 may not transmit any data. At the preconfigured resource time domain location, the UE 220 may switch from an RRC idle state T2A to an RRC idle mode USS monitoring status T3A.

Step 207A: Upon receipt of information transmitted from the MME 240, a downlink PDCCH search space corresponding to a pre-configured dedicated resource may use a dedicated Radio Network Temporary Identifier (RTNI) to perform downlink resource scheduling and/or downlink data transmission to the UE 220. The eNB 230 may transmit downlink data to the UE 220 using a physical downlink control channel (PDCCH) for downlink (DL) grant.

Step 208A: The eNB 230 may transmit a physical downlink shared channel (PDSCH) message to the UE 220. The PDSCH message may include a NAS PDU.

Step 209A: The eNB may transmit an initial UE message to the MME 240. After the eNB 230 receives the information sent by the core network 240, if the UE 220 has a corresponding pre-configured dedicated resource in the eNB 230, the eNB 230 triggers the connection establishment of a UE Specific type of the eNB 230to the MME 240.

Step 210A: The MME 240 may transmit an initial context setup request to the eNB 230.

Step 211A: The eNB 230 may transmit an initial context setup response to the MME 240. This message may be transmitted based on receipt of the initial context setup request 210A.

Step 212A: The MME 240 may transmit a downlink NAS transport message to the eNB 230.

Step 213A: The eNB 230 may transmit an RRC connection release message to the UE 220. The RRC connection release message 213 may request the UE 220 to switch from a RRC idle mode USS monitoring status T3A to a RRC idle mode T4A.

Step 214A: The eNB 230 and MME 240 may communicate via a UE-specific S1 release procedure.

FIG. 2B illustrates a PUR release indication procedure. In Step 201B, the eNB may transmit a PUR resource release message to the UE 220 indicating the UE 220 to release a PUR resource. The UE 220 may switch from a last RRC connection status or a PUR data transfer status T1B to an RRC idle state T2B based on receipt of the PUR resource release message 201B.

Step 202B: After the eNB 230 sends the PUR resource release message 201B to the UE 220, the eNB may transmit a PUR-specific resource release message to the MME 240. The PUR-specific resource release message 202B may include PUR resource release instructions instructing the MME to release the PUR resource. The PUR-specific resource release message 202B may be transmitted using UE-specific signaling, such as a UE CONTEXT RELEASE REQUEST message or other dedicated message sent to the MME 240.

Step 203B: The MME 240 may transmit a UE context release command to the eNB 230.

Step 204B: The eNB 230 may transmit a UE context release complete message to the MME 240 indicating that the release procedure is complete.

FIG. 2C illustrates a user plane (UP) PUR release indication procedure. In step 201C, the eNB 230 may transmit an idle mode data transfer status dedicated pre-configuration message to the terminal 220. The message may include pre-configured idle mode data transfer dedicated resources and a terminal-specific PDCCH search space.

Step 202C: The eNB 230 may transmit a RRC connection release message to the UE 220. The UE 220 may switch from the last RRC connection status T1C to the RRC idle state T2C based on receiving the RRC connection release message 202C.

Step 203C: The eNB 230 may transmit a message to a MME 240 that includes the time domain location of the dedicated PUR resource. After the eNB 230 pre-configures the PUR dedicated resource to the UE 220, the time domain location of the dedicated resource may be sent to the MME 240 by using the UE specific signaling. The UE Specific signaling may be a UE CONTEXT SUSPEND REQUEST message or another dedicated message sent to the MME 240.

Step 204C: The MME 240 may transmit a UE context suspend response to the eNB in response to receiving the UE context suspend request 203C from the eNB 230.

Step 205C: The MME 240 may transmit paging and/or downlink data to the eNB 230. When the core network 240 has downlink data to be transmitted, one of the following information may be sent to the eNB 230 in the time domain location of the PUR: Paging information, Paging information and data, data and the NAS identifier of the UE 220. The NAS identifier of the UE 220 may be an STMSI or an identifier of a similar identifiable UE. The paging and downlink data 205C may be transmitted at the preconfigured resource location, where UE 220 may not need to transmit uplink data. The UE 220 may transition from the RRC idle state T2C to a RRC idle mode USS monitoring status T3C at the preconfigured resource location.

Step 206C: The eNB 230 may transmit a PDCCH for DL grant to the UE 220. When the eNB 230 receives the paging and/or downlink data sent by the core network, a downlink PDCCH search space corresponding to the pre-configured dedicated resource may use a dedicated RNTI to perform downlink resource scheduling and/or downlink data transmission to the UE 220.

Step 207C: The eNB 230 may transmit a PDSCH message to the UE 220 that may include downlink (DL) data.

Step 208C: After the eNB 230 receives the information sent by the core network 240, if the UE 220 has a corresponding pre-configured dedicated resource in the eNB 230, the eNB 230 may trigger the connection establishment of the UE Specific type of the eNB 230 to the MME 240. The eNB 230 may transmit a UE context resume message or another similar message to the MME 240.

Step 209C: The eNB 230 may transmit a UE context resume response to the MME 240. This message may be transmitted based on receipt of the UE context resume request 208C.

Step 210C: The MME 240 may transmit a downlink NAS transport message to the eNB 230.

Step 211C: The eNB 230 may transmit a RRC connection release message to the UE 220. The UE 220 may transition from an RRC idle mode USS monitoring status T3C to a RRC idle state T4C based on the UE 220 receiving the RRC connection release 211C.

Step 212C: After the eNB 230 sends the pre-configured PUR-specific resource release indication to the MME 240, the eNB 230 may send the pre-configured PUR-specific resource release indication to the MME 240 by using the UE specific signaling. The UE Specific signaling may be a UE CONTEXT SUSPEND REQUEST message or another dedicated message sent to the MME 240.

Step 213C: The MME 240 may transmit a UE context suspend release message to the eNB 230 based on receiving the UE context suspend request 212C from the eNB 230.

FIG. 2D illustrates a user plane PUR release indication. In step 201D, the eNB 230 may transmit pre-configured PUR resource release indication to the UE 220. This indication 201D may request the UE 220 to transition from a last RRC connection state or PUR resource transfer status T1D to an RRC idle state T2D.

Step 202D: After the eNB 230 sends the pre-configured PUR-specific resource release indication 201D to the UE 220, the eNB 230 may send the pre-configured PUR-specific resource release indication to the MME 240 by using the UE specific signaling. The UE Specific signaling may be a UE CONTEXT SUSPEND REQUEST message or another dedicated message sent to the MME 240. The UE context suspend request message may include PUR resource release instructions.

Step 203D: The MME 240 may transmit a UE context suspend responds to the eNB 230 based on receiving the UE context suspend request from the eNB 230.

FIG. 2E illustrates a dedicated signaling release for a PUR resource. In Step 201E, the eNB 230 may transmit a message indicating a request to configure or reconfigure PUR resources to the UE 220. The UE 220 may transition from the last RRC connection state or PUR transfer status T1E to an RRC idle state T2E based on receipt of message 201E.

Step 202E: A PUR resource reconfiguration or release request may transition the UE 220 from the RRC idle state T2E to an RRC idle mode USS monitoring status T3E.

Step 203E: The eNB 230 mat transmit a PUR resource reconfiguration or release indication to the UE, where the UE 220 may transition from the RRC idle mode USS monitoring status T3E to the RRC idle state T4E.

Step 204E: When the dedicated PUR resource is updated or released, the PUR resource time domain location update or the PUR resource release indication is notified to the MME 240. In an embodiment, there is no terminal-specific connection between the eNB 230 and the MME 240, and a UE identifier and the reconfiguration/release indication may be included in a message.

After the eNB 230 sends the pre-configured PUR dedicated resource time domain reconfiguration or the PUR resource release indication to the UE 220, the eNB 230 may send the time domain location reconfiguration information or the PUR resource release indication of the preconfigured PUR dedicated resource to the MME 240 by using the UE specific signaling. The UE specific signaling may carry at least one of the following messages: a UE NAS identifier (such as S-TMSI) , and the time domain location information or the PUR resource release indication of the pre-configured PUR dedicated resource.

Step 205E: After receiving the PUR dedicated resource time domain reconfiguration or PUR resource release indication, the MME 240 may transmit a PUR resource time domain location update or PUR resource release and may send a response or acknowledgement message to the eNB 230. The reconfiguration or release process of the PUR resource may end upon transmission of the PUR resource update or release response 205E. The RRC idle mode USS monitoring state may include to a PDCCH search space corresponding to an uplink dedicated resource of the idle mode, and the UE may monitor the PDCCH search space corresponding to the uplink dedicated resource at the resource location.

Example Embodiment 2:

FIGS. 3A-D illustrate examples of data transmission based on pre-configured dedicated resources. In FIG. 3A, step 301A illustrates that the eNB 330 may transmit an idle mode data transfer status dedicated pre-configuration message to the terminal 320. The message may include pre-configured idle mode data transfer dedicated resources and a terminal-specific PDCCH search space.

Step 302A: the eNB 330 may transmit a RRC connection release message to the UE 320. This RRC connection release message may include a pre-configured PUR resource. The UE 320 may transition from the last RRC connection status T1A to the RRC idle state T2A upon receiving the RRC connection release message.

Step 303A: the eNB 330 may transmit a message to the MME 340 using UE-specific signaling. The UE specific signaling may be a UE CONTEXT RELEASE REQUEST or another dedicated message.

Step 304A: The MME 340 may transmit a UE CONTEXT RELEASE COMMAND to the eNB 330 based on receiving the UE CONTEXT RELEASE REQUEST 303A.

Step 305A: The eNB 330 may transmit a UE CONTEXT RELEASE COMPLETE message to the MME 340 indicating that the UE context release request was completed.

Step 306A: The eNB 330 may transmit an initial UE message before or at a time domain location of the dedicated resource (or “PUR timing” ) to the MME 340. After the eNB 330 receives the information sent by the core network 340, if the UE 320 has a corresponding pre-configured dedicated resource in the eNB 330, the eNB 330 may trigger the connection establishment of a UE Specific type of the eNB 330 to the MME 340. The UE 220 mat transition from a RRC idle state T2A to a RRC idle mode USS monitoring status T3A at the preconfigured resource location.

The eNB 330 may trigger the establishment of a connection to the MME 340 via an interface (e.g., a S1 interface) . Establishing such a connection to the MME 340 may not depend on the receipt of uplink data resources at the PUR timing (preconfigured time domain location) . Upon establishing an interface, such as a S1 interface, the MME 340 may transmit downlink data to the eNB 330. The eNB 330 may utilize downlink resource scheduling for the downlink PDCCH search space and resources RNTI PUR to transmit downlink data to the UE 320.

Step 307A: The MME 340 may transmit an initial context setup request to the eNB 330.

Step 308A: The eNB 330 may transmit an initial context setup response to the MME 340. This message may be transmitted based on receipt of the initial context setup request 307A.

Step 309A: The MME 340 may transmit a downlink NAS transport message to the eNB 330.

Step 310A: The eNB 330 may transmit an PDCCH message for a downlink (DL) grant to the terminal.

Step 311A: The eNB 330 may transmit an PDSCH message to the UE 320 that includes a NAS PDU.

Step 312A: The eNB 330 may transmit an RRC connection message to the UE 320. The UE 320 may transition from a RRC idle mode USS monitoring status T3A to a RRC idle state T4A based on receiving the RRC connection message 312A.

Step 313A: the eNB 330 may transmit a message to the MME 340 using UE-specific signaling. The UE specific signaling may be a UE CONTEXT RELEASE REQUEST or another dedicated message.

Step 314A: The MME 340 may transmit a UE CONTEXT RELEASE COMMAND to the eNB 330 based on receiving the UE CONTEXT RELEASE REQUEST 313A.

Step 315A: The eNB 330 may transmit a UE CONTEXT RELEASE COMPLETE message to the MME 340 indicating that the UE context release request was completed.

FIG. 3B illustrates pre-configured data transfer for dedicated resources in idle mode. In FIG. 3B, step 301B illustrates that the eNB 330 may transmit an idle mode data transfer status dedicated pre-configuration message to the terminal 320. The message may include pre-configured idle mode data transfer dedicated resources and a terminal-specific PDCCH search space.

Step 302B: the eNB 330 may transmit a RRC connection release message to the UE 320. This RRC connection release message may include a pre-configured PUR resource. The UE 320 may transition from the last RRC connection status T1B to the RRC idle state T2B upon receiving the RRC connection release message.

Step 303B: the eNB 330 may transmit a message to the MME 340 using UE-specific signaling. The UE specific signaling may be a UE CONTEXT SUSPEND REQUEST or another dedicated message.

Step 304B: The MME 340 may transmit a UE CONTEXT SUSPEND RESPONSE to the eNB 330.

Step 305B: the eNB 330 may transmit a UE CONTEXT RESUME REQUEST before or at a time domain location of the dedicated resource (or “PUR timing” ) to the MME 340. The location of a CP PUR resource may trigger the establishment of an S1 interface connection between eNB 330 and MME 340.

If the UE 320 monitors the PDCCH search space corresponding to a PUR resource, the eNB 330 may trigger the establishment of the UE Specific connection between the eNB 330 and the core network 340 as long as the PUR resource location is reached. If the UE 320 does not send uplink data over the PUR resource, the uplink data to eNB 330, but the UE 320 still monitors the PDCCH search space corresponding PUR resource, the eNB 330 may establish a UE Specific connection between the eNB 330 and the core network 340 at the PUR resource location.

Step 306B: The MME 340 may transmit a UE CONTEXT RESUME RESPONSE to the eNB 330 based on receiving the UE CONTEXT RESUME REQUEST 305B.

Step 307B: The MME 340 may transmit a downlink NAS transport message to the eNB 330.

Step 311B: the eNB 330 may transmit a message to the MME 340 using UE-specific signaling. The UE specific signaling may be a UE CONTEXT SUSPEND REQUEST or another dedicated message.

Step 312B: The MME 340 may transmit a UE CONTEXT SUSPEND RESPONSE 312B to the eNB 330 based on receiving the UE CONTEXT SUSPEND REQUEST 311B.

FIG. 3C illustrates a determinization of whether paging can include user data based on preconfigured dedicated resource configurations. In Step 301C, the eNB 330 transmits a configure/reconfigure PUR resources message to the UE 320. The UE 320 may transition from a last RRC connection status T1C to a RRC idle state T2C.

Step 302C: the eNB 330 may transmit a PUR resource configuration/reconfiguration request to the MME 340. When the eNB configures or reconfigures the PUR resource, the eNB 330 may send the PUR resource configuration or reconfiguration information to the MME 340.

The sending of the PUR resource configuration or reconfiguration information to the MME may be performed by one of the following: a UE Specific S1 interface signaling sent by the eNB 330 to the MME 340 (e.g., UE CONTEXT RELEASE REQUEST, UE CONTEXT RELEASE COMPLETE, UE CONTEXT MODIFICATION RESPONSE, UE CONTEXT MODIFICATION FAILURE, UE RADIO CAPABILITY MATCH RESPONSE, UE CONTEXT MODIFICATION INDICATION, UE CONTEXT SUSPEND REQUEST, UE CONTEXT RESUME REQUEST, INITIAL UE MESSAGE, NAS NON DELIVERY INDICATION, NAS DELIVERY INDICATION, etc. ) . The PUR resource configuration or reconfiguration information may be time domain location information of the PUR resource, PUR resource presence indication information, or other information related to the PUR resource configuration.

Step 303C: The MME 340 may transmit paging information to the eNB 330. When the MME 340 has downlink data to be sent to the UE 220, if the UE 320 has the PUR resource configuration, the MME 340 may include the data in the Paging message. If the UE 320 does not have the PUR resource configuration, the MME 340 may first send the eNB 330 paging message is sent, and then transmit the downlink data to the eNB 330 after receiving a message in response to the first paging message.

Step 304C: the eNB 330 may transmit a PDCCH associated with a common RNTI over PDCCH common search space (CSS) to the UE 320. When the eNB 330 receives a paging message (with or without user data) message, if the UE 320 has a pre-configured PUR resource, the UE 320 may perform DL Grant scheduling on the CSS-Paging and send the DL Grant to the UE 320. The common RNTI may include at least one of: a Paging-RNTI, a common RNTI for Paging with data, a common RNTI for data. The PDCCH common search space may include at least one of: a PDCCH search space for paging, a PDCCH common search space for Paging with data, a PDCCH common search space for data. The PDCCH common search space may include at least one of: sent by a SIB, sent by a dedicated RRC signaling, a CSS set sent by SIB and a UE specific index to the CSS sent by a dedicated RRC signaling, a CSS sent by SIB and a UE specific PDCCH repetition number sent by a dedicated RRC signaling.

Step 305C: The eNB 330 may transmit a PDSCH message to the UE 320. The PDSCH channel may carry dedicated resource configuration information and/or downlink user data in a paging message. The dedicated resource configuration information may include at least one of the following: a UE-specific RNTI (such as a C-RNTI) , an uplink grant resource (UL Grant) used for at least one of Scheduling Request (SR) , Buffer Size Report (BSR) , ack for the DL user data, a PDCCH search space (such as a USS) corresponding to the dedicated resource, and a PDCCH search space monitoring time.

Step 306C: The UE 320 may transmit a PUSCH message to the eNB 330. When the UE 320 receives the PDSCH channel, if data is carried on the PDSCH channel, the UE 320 may confirm the data by using the PUSCH over UL Grant. If there is no data on the PDSCH channel, the UE 320 may send a message to the eNB 320 through the PUSCH over UL Grant including at least one of a RRC Msg3, a SR, a BSR, a Paging Acknowledge. This message may trigger the S1 interface UE Specific connection establishment so that the MME 340 may transmit downlink data to the eNB 330.

Step 307C: The eNB 330 may transmit a PDCCH message to the UE 330.

Step 308C: The eNB 330 may transmit a paging response message to the MME 340. When the eNB 330 receives the acknowledgment of the data from the UE 320 through the PUSCH over UL Grant, the eNB 330 may transmit a Paging acknowledgment to the MME 340 and the downlink data transmission is completed.

FIG. 3D illustrates transmitting paging information and downlink data to the terminal 320. In Step 301D, the eNB 330 may transmit a message to configure or reconfigure PUR resources to the UE 320. The UE 320 may transition from the last RRC connection status T1D to a RRC idle state T2D based on receiving the message 301D.

Step 302D: the MME 340 may transmit a paging message to the eNB 330 (without carrying any downlink user data) .

Step 303D: The eNB 330 may directly trigger the establishment or recovery of the UE Specific signaling of the S1 interface based on the PUR resource configuration information, so that the MME 340 sends the user data to the eNB 330. Establishing the S1 interface may be triggered by one of the following messages: UE CONTEXT RESUME REQUEST, INITIAL UE MESSAGE or another newly added SI port UE Specific signaling.

Step 304D: After the S1 interface connection establishment or recovery of the UE is completed, the MME 340 may send the downlink data to the eNB 330.

Step 305D: After receiving the downlink data of the user, the eNB 330 may perform DL Grant scheduling on the UE 320 through PDCCH associated with a common RNTI over PDCCH common search space (CSS) . The common RNTI may include at least one of: a Paging-RNTI, a common RNTI for Paging with data, a common RNTI for data. The PDCCH common search space may include at least one of: a PDCCH search space for paging, a PDCCH common search space for Paging with data, a PDCCH common search space for data.

Step 306D: The eNB 330 may transmit a PDSCH message over a PDSCH channel on the DL Grant. The PDSCH channel may carry dedicated resource configuration information and downlink user data. The dedicated resource configuration information may include at least one of the following: a UE-specific RNTI (such as a C-RNTI) , an uplink grant resource (UL Grant) used for at least one of Scheduling Request (SR) , Buffer Size Report (BSR) , ack for the DL user data, a PDCCH search space (such as a USS) corresponding to the dedicated resource, and a PDCCH search space monitoring time.

Step 307D: the UE 320 may transmit a PUSCH message over the UL grant to the eNB 330. The message 307D may include at least one of a RRC Msg3, a SR, a BSR, a Paging Acknowledge, a DL data Acknowledge.

Step 308D: The eNB 330 may transmit a PDCCH message to the UE 320.

Step 309D: After the uplink and downlink data transmission is completed, the eNB 330 may trigger the S1 interface UE specific connection release or suspension process with the MME 340. The S1 interface UE specific may be released based on receiving one of the following messages: a UE CONTEXT SUSPEND REQUEST, a UE CONTEXT RELEASE REQUEST or another newly added SI interface UE Specific signaling.

Example Embodiment 3:

FIGS. 4A-C illustrates examples of processing a coupling between paging information and preconfigured dedicated resources. FIG. 4A illustrates an example of paging and PUR coupling. The eNB 430 may receive a paging message (paging 403A) from a MME 440 within a predefined time period before a valid preconfigured dedicated resource (e.g., PUR) . In other words, the time interval between the paging message and the preconfigured dedicated resource is less than a predetermined time length. The eNB 430 may determine to delay the paging message (paging 403A) based on the PUR.

If the UE 420 still monitors the terminal-specific PUR search space (PUR-USS) even it does not transmit uplink data on the PUR, the eNB 430 may initiate a UE specific S1 connection establishment or recovery (e.g., S1 connection establishment or recovery 404A upon receiving a paging message (paging 403A) from a MME 440 before the PUR resource location.

The eNB 430 may receive downlink data (e.g., downlink data 405A) from the MME 440 on the UE specific S1 connection. The eNB 430 may send PDCCH with the PDCCH search space that corresponds to a relevant PUR resource, where the downlink PDCCH may include using a dedicated RNTI to perform downlink resource scheduling for downlink data transmission to the UE 420.

FIG. 4B illustrates an example of paging and PUR coupling. A preconfigured dedicated resource-specific PDCCH search space (PUR-USS) may not be monitored if the UE 420 does not transmit data (uplink data) at the PUR resource location (e.g., preconfigured resource location 406B) . If the eNB 430 receives uplink data on the PUR resource (e.g., at the preconfigured resource location 406B) , the eNB 430 may trigger an establishment of an S1 interface with the MME 440 (S1 connection establishment or recovery 404B) . In this event, the eNB 430 may not transmit a paging message to the UE 420.

FIG. 4C illustrates an example of paging and PUR coupling when a terminal 420 does not transmit data. The eNB 430 may not receive uplink data on the PUR resource from the UE 420 (e.g., preconfigured resource location (uplink data not sent) 404C) . In this event, the eNB 430 may not monitor a PDCCH search space corresponding with the PUR. After the ending of the PUR resource (or preconfigured resource location) , the eNB 430 may schedule a paging message (paging 406C) to be sent to the UE 420 through CSS-paging.

In any of FIGS. 4A-C, the predefined time period may include a duration that does not exceed a MME 440 paging retransmission timer (e.g., 15 seconds) if the paging message does not carry a paging eDRX parameter. The predefined time period may be a duration that does not exceed a minimum (e.g., the MME 440 paging retransmission timer, paging time window (PTW) length) if the paging messages carrier a eDRX parameter. The valid PUR resource may identify that the PUR resource may be configured for the UE 420, and the PUR resource is available (e.g. TA is valid, and the cell reselection does not occur etc) . The paging retransmission timer may be defined by a communication node and/or sent from the core network, and the communication node may be configured to define and/or modify the predetermined time duration.

Example Embodiment 4:

FIG. 5 illustrates a pre-configured dedicated resource PDCCH common search space configuration. In Step 501: The eNB 530 configures a PDCCH common search space (CSS) corresponding to the PUR resource for the UE 520. The PUR-CSS configuration information may be sent to the UE 520 via a system information block (SIB) . The PDCCH CSS may include at least one of a PDCCH monitoring mode sets with different enhanced coverage level configurations, a PDCCH monitoring mode without enhanced coverage level differentiation.

Each PDCCH monitoring mode may include a starting position of PDCCH monitoring or a parameter for determining a PDCCH monitoring starting position, a time interval for PDCCH monitoring, a parameter for determining a PDCCH monitoring time interval, and a maximum number of repetitions of the PDCCH.

Step 502A: The eNB 530 may configure a PUR dedicated resource and at least one of a PUR-CSS index and a PDCCH repetition number corresponding to the PUR dedicated resource. The eNB 530 may transmit the configuration to UE 520 during the last RRC connection state when configuring the PUR dedicated resource for idle mode data transmission. The UE 520 may monitor a monitoring duration of the PUR-CSS from the PUR dedicated resource location. The eNB 530 may transmit an idle Mode data Transfer status dedicated resource pre-configuration that includes a re-configured idle mode data transfer dedicated resource and a PUR-CSS index.

Step 502B: The eNB 530 may configure the PUR-specific resource and at least one of a PUR-CSS index and a PDCCH repetition number corresponding to the PUR specific resource and the monitoring duration of the PUR-CSS by using the RRC connection release message in the RRC connection state or the PUR resource-based data transmission state. The PUR-CSS index corresponding to the PUR dedicated resource may include a coverage level index at which the UE 520 is located.

Example Embodiment 5:

FIGS. 6A-H illustrate various terminal-specific pre-configured dedicate resource configuration methods. The eNB 630 may configure a PUR resource for a terminal 620, where the terminal 620 may be configured to configure at least one of a UE-specific PUR PDCCH search space, a maximal monitoring during (PUR-USS-Duration) and a monitoring timer (PUR-USS-Timer) , UE specific RNTI corresponding to the PUR PDCCH search space. Wherein the UE specific RNTI corresponding to the PUR PDCCH is valid only when the terminal 620 monitors the PUR PDCCH search space or during the pur-USS-Duration from the beginning of PUR-USS monitoring.

The UE-specific PUR PDCCH search space (PUR USS) may include a start position of PDCCH monitoring or a parameter for determining a PDCCH monitoring start position, a time interval for PDCCH monitoring, a parameter for determining a PDCCH monitoring time interval, and a PDCCH maximum number of repetitions. The UE 620 may start or restart the PUR-USS-Timer when the PUR-USS monitoring starts or when there is no data transmission and reception. If the PUR-USS-Timer times out, the UE 620 may enter a RRC idle mode.

In FIG. 6A, if the UE does not send data on the PUR resource (e.g., pre-configured resource location (UE does not send data) 602A) , the timer (PUR-USS-Timer) may be started in the PUR resource location, and the UE 620 may enter the PUR-USS monitoring state T3A. If the timer expires and the PDCCH scheduling information is not monitored, the UE 620 enters an idle state T4A.

In FIG. 6B, if a UE 620 does not transmit any data on the PUR (or preconfigured resource location) and also monitors a terminal-specific preconfigured PDCCH search space (PUR-USS) , a preconfigured resource timer (PUR-USS-Timer) may start at a PUR resource location. If the PDCCH scheduling information is monitored before the timer expires, the UE 620 may perform data transmission and reception based on the scheduling information. When data is sent and received, the UE 620 may start or restart the timer (PUR-USS-Timer) , and if the timer expires, the UE 620 may enter an idle state T4B.

In FIG. 6C, if the UE 620 does not monitor a PUR-USS without transmitting data on the PUR, if the UE 620 does not send data on the PUR resource, the UE 620 may enter an idle mode. For example, monitoring the idle mode may include scheduling the paging space CSS-Paging.

In FIG. 6D, if the UE 620 performs data transmission on the PUR resource, the timer (PUR-USS-Timer) may be started or restarted after the data transmission and reception is completed. If the timer expires, the UE may enter an idle state T4B. If the eNB 630 wants the UE 620 to stop PUR-USS monitoring before the timer expires, or if it wishes to reconfigure the PUR resource, the eNB 630 may send an instruction (PDCCH for ack or DL grant 603D) to the UE 620 to notify the PUR-USS to stop monitoring before the timer expires. The instruction may be indicated by a PDCCH DCI, a downlink MAC CE scheduled by the PUR-USS, an RRC dedicated signaling scheduled by the PUR-USS, or an acknowledgement indication of the uplink data. After receiving the relevant indication, the UE 620 may perform an indication response, and/or stops monitoring of the PDCCH search space.

In FIG. 6E, if the UE 620 performs data transmission on the PUR resource, the timer (PUR-USS-Timer) may be started or restarted after the data transmission and reception is completed. If the eNB 630 wants the UE 620 to transition to the RRC connection state T4E, a status indication command (e.g., RRC reconfiguration or RRC setup/resume 604E) may be sent to the UE 620 before the PUR-USS-Timer may time out, indicating that the UE 620 transitions to the RRC connected state. The status indication command 604E may be a RRC connection establishment message, RRC connection resume message, RRC connection reconfiguration message, a newly defined RRC dedicated downlink signaling message, a medium access control (MAC) control element (CE) including the indication command, or a PDCCH DCI including the indication command. The RRC reconfiguration or RRC setup/resume message 604E may carry a C-RNTI.

If the UE 620 receives the indication command, the UE 620 may transition to the RRC connection state based on the indication command 604E. If the C-RNTI is carried in the instruction 604E, the UE 620 may use the C-RNTI in the RRC connected mode T4E. If the C-RNTI is not carried in the instruction 604E, the UE 620 may use the RNTI (aPDCCH that scrambles the original RNTI) that the UE used before receiving the indication 604E.

In FIG. 6F, in the PUR-USS monitoring process, even if the eNB 630 sends a PDCCH Order 604F to the UE 620, the PUR-USS is still monitored.

In FIG. 6G and FIG. 6H, during the PUR-USS monitoring process, the PUR-USS may be monitored even if the eNB 630 sends a PDCCH order message to the UE 620. During the PUR-USS monitoring process, if the eNB 630 sends a PDCCH Order (PDCCH order 604G) to the UE 620, the UE 620 may be switched from PUR-USS monitoring to CSS-RA monitoring (if the PUR-USS-Timer is running, it may stop) . When the UE receives a RAR or TA Update indication (607) (for example: Timing Advance Command MAC CE) or the UE sends uplink data or contention completion indication (such as C-RNTI MAC CE) to the UE after receiving the RAR, then CSS-RA monitoring ends, the UE 620 may start monitoring the PUR-USS.

Example Embodiment 6:

FIG. 7 illustrates an example PUR pattern. When a PUR resource is configured for the UE 720, the PUR pattern corresponding to the traffic pattern may be configured for the UE 720. The PUR Pattern may include a PUR transmission start time, a periodic PUR transmission interval, a maximum valid duration of a periodic PUR resource, a valid timer, and superposition information of a plurality of service patterns.

The PUR transmission start time may be expressed by absolute time (for example: PUR transmission start time PUR-TransmissionStartTime, such as YY: MM: DD: HH: MM: SS; radio frame RF and radio subframe SF at which PUR resource transmission starts. In an embodiment, the PUR transmission start time may be expressed by relative time, such as an offset value relative to an absolute time.

The superposition of the plurality of service modes may include a transmission time sequence expressed in a valid bit sequence (e.g., dayofWeek BIT STRING (SIZE (7 ) ) or dayofMonth BIT STRING (SIZE (31 ) ) , hourofDay BIT STRING (SIZE (24 ) ) ) . The superposition of the plurality of service modes may include a set of configuration sets of multiple service patterns, where each set of service patterns corresponds to a configuration index and is used for reconfiguration, release, scheduling, etc., of the service pattern. The superposition of the plurality of service patterns may include the superposition of a transmission time series with multiple sets of service pattern configuration sets.

As an example, a PUR-TransmissionStartTime is set to: 2019-01-01 00: 00: 00 RF=0, SF=0, and dayofWeek is set to: 118000. The periodic PUR-Duration is set to: 30 days. Then, from the 2019-01-01 00: 00: 00, the first occurrence of the RF0, SF0 is the starting position of the first PUR resource. Thereafter, the RF0, SF0, which appears for the first time after 00: 00: 00 on Monday, Tuesday, and Wednesday, has a PUR resource location. The PUR resource appears in this pattern and does not appear until 2019-01-30 23: 59: 59.

The transmission sequence of the one UE may also be split into multiple sets of PUR resource configuration sets. For example, three resource sequences can be expressed as:

{PUR configuration index 1:

The start time of PUR resource block 1; //2019-01-01 00: 00: 00;

Period and/or interval of PUR resource block 1; //1 week;

Scheduling information of PUR resource block 1;

PUR resource block 1 valid duration; //29～30 days;

PUR configuration index 2:

The start time of PUR resource block 2; //2019-01-02 00: 00: 00;

Period and/or interval of PUR resource block 2; //1 week;

Scheduling information of PUR resource block 2;

PUR resource block 2 valid duration; //28～29 days

PUR configuration index 3:

The start time of PUR resource block 3; //2019-01-07 00: 00: 00;

Period and/or interval of PUR resource block 3; //1 week;

Scheduling information of PUR resource block 3;

PUR resource block 3 valid duration; //22～24 days

}.

For example, three resource sequences can also be expressed as:

{

The start time of PUR resource;

PUR resource valid duration;

{

PUR configuration index 1:

Time offset of PUR resource block 1 start time relative to the start time of PUR resource: 0 seconds;

Period and/or interval of PUR resource block 1; //1 week;

Scheduling information of PUR resource block 1;

PUR configuration index 2:

Time offset of PUR resource block 2 start time relative to the start time of PUR resource: : //1 day;

Period and/or interval of PUR resource block 2; //1 week;

Scheduling information of PUR resource block 2;

PUR configuration index 3:

Offset of PUR resource block 3 start time relative to the start time of PUR resource; //6 days;

Period and/or interval of PUR resource block 3; //1 week;

Scheduling information of PUR resource block 3

}

}.
