Device-to-device communication is a D2D-based sidelink transmission technology (Sidelink, SL). Different from the traditional cellular system in which communication data is received or sent through the base station, the Internet of Vehicles system adopts the method of terminal-to-terminal direct communication. , so it has higher spectral efficiency and lower transmission delay.

FIG. 1 is a schematic diagram of a communication system provided by an embodiment of the present application. The transmission resources of the vehicle-mounted terminals (the vehicle-mounted terminal 121 and the vehicle-mounted terminal 122 ) are allocated by the base station 110 , and the vehicle-mounted terminal transmits data on the sidelink according to the resources allocated by the base station 110 .

Optionally, the in-vehicle terminal may randomly select transmission resources, or select transmission resources by means of listening.

The embodiments of the present application may be applied to the communication system shown in FIG. 1 above.

To facilitate a better understanding of the embodiments of the present application, terms related to the present application are described.

Proximity-based Services (ProSe): Device-to-device communication in version 12 (release12, Rel-12) or version 13 (release13, Rel-13) is studied for ProSe scenarios, which are mainly for public Security business.

In ProSe, by configuring the location of the resource pool in the time domain, for example, the resource pool is not continuous in the time domain, so that the UE can send/receive data discontinuously on the sidelink, thereby achieving the effect of power saving.

Internet of Vehicles (V2X): In version 14 (release14, Rel-14) or version 15 (release15, Rel-15), the Internet of Vehicles system has been studied for the scenario of vehicle-to-vehicle communication, which is mainly for relatively high-speed moving vehicles , Vehicle-to-person communication business. In V2X, since the vehicle system has continuous power supply, power efficiency is not the main problem, but the delay of data transmission is the main problem. Therefore, the terminal equipment is required to perform continuous transmission and reception in system design.

Wearable Devices (FeD2D): In Rel-14, this scenario studies the scenario of wearable devices accessing the network through mobile phones, which is mainly oriented to scenarios with low mobile speed and low power access. In FeD2D, in the pre-research stage, 3GPP concluded that the base station can configure the DRX parameters of the remote terminal through a relay terminal.

In order to facilitate a better understanding of the embodiments of the present application, the NR V2X related to the present application is described.

On the basis of LTE V2X, NR V2X is not limited to broadcast scenarios, but is further extended to unicast and multicast scenarios, and the application of V2X is studied in these scenarios.

Similar to LTE V2X, NR V2X also defines two resource authorization modes, Mode 1 (corresponding to the communication system shown in Figure 1 above) and Mode 2 (corresponding to the communication system shown in Figure 2 above); further, users may In a mixed mode, that is, you can use Mode 1 to acquire resources, and you can use Mode 2 to acquire resources at the same time. The resource acquisition is indicated by means of sidelink authorization, that is, the sidelink authorization indicates the corresponding Physical Sidelink Control Channel (PSCCH) and Physical Sidelink Shared Channel (PSSCH) resources time-frequency location.

Unlike LTE V2X, in addition to the non-feedback, UE-initiated Hybrid Automatic Repeat reQuest (HARQ) retransmission, NR V2X introduces feedback-based HARQ retransmission, which is not limited to unicast communication, but also includes group broadcast communication.

Similar to LTE V2X, in NR V2X, since the on-board system has continuous power supply, power efficiency is not the main problem, but the delay of data transmission is the main problem, so the terminal equipment is required to perform continuous transmission and reception in system design.

In order to facilitate a better understanding of the embodiments of the present application, an NR-V2X Mode 1 (Mode 1) resource acquisition method related to the present application is described.

In the resource allocation method based on network scheduling, it is divided into dynamic authorization and configuration authorization (Configured Grant, CG). For dynamic authorization, the network allocates sidelink transmission resources to the terminal through Downlink Control Information (DCI); in Release 16 (release16, Rel-16) NR-V2X, the uplink CG mechanism is introduced, and the sidelink configuration is introduced Licensing (Sidelink CG, SL CG). When the terminal is configured with sideline configuration authorized transmission resources, and when sideline data arrives, the terminal can use the sideline configuration authorized transmission resources to transmit the sideline data without re-applying to the network for transmission resources. Configuring authorized transmission resources can reduce the delay of sideline transmission. The transmission resource authorized by the sideline configuration is a periodic transmission resource, so it can be applied to the transmission of periodic sideline data, and of course, it can also be used to transmit aperiodic sideline data.

When the terminal has sidelink data to send, the terminal sends a resource request to the base station, including a Scheduling Request (SR) and a Buffer Status Report (BSR), and the base station allocates a sidelink to the terminal according to the BSR of the terminal For transmission resources, the terminal sends sideline data on the sideline transmission resources allocated by the base station, as shown in FIG. 3 .

In order to facilitate a better understanding of the embodiments of the present application, a side-line BSR (SL-BSR) mechanism related to the present application is described.

The terminal device sends a scheduling request (SR or random access) to the base station, and then sends an SL-BSR. As shown in Figure 4, the BSR can at least include a destination address index (destination index), a logical channel group identity (Logical Channel Group Identity, LCG ID) and buffer size. Based on the sidelink BSR, the base station can determine that the terminal device has data to transmit for sidelink communication and estimate the resources required to transmit the data. The base station may use the configured radio network temporary identity (Radio Network Temporary Identity, RNTI) for sidelink to schedule transmission resources for sidelink communication.

For the trigger of SL-BSR, there are the following trigger conditions:

The new data to be transmitted appears in the Radio Link Control (Radio Link Control, RLC) entity or the Packet Data Convergence Protocol (PDCP) entity (if there is other data to be transmitted, the new data has a higher priority than the same Any logical channel group of the target address has a higher priority for data to be transmitted, or agrees that the target address has no other data to be transmitted at present);

After allocating the resource grant space for the data and triggering the padding BSR for the uplink channel, the number of remaining bits is equal to or greater than the size of the sidelink BSR (buffer information of at least one logical channel group containing at least one target address);

The sidelink BSR retransmission timer expires, and the media access control (Media Access Control, MAC) entity has data available for sidelink transmission;

The sidelink BSR periodic timer expires;

The sidelink BSR can also be triggered when the terminal device is configured from the autonomous resource selection mode to the network scheduling resource selection mode.

For better understanding of the embodiments of the present application, the DRX related to the present application is described.

The UE will discontinuously monitor the Physical Downlink Control Channel (PDCCH) according to the DRX configuration to save power. When the PDCCH carries the Cell Radio Network Temporary Identity (C- RNTI), cancel indication RNTI (Cancellation indication RNTI, CI-RNTI), configure scheduling RNTI (Configured Scheduling RNTI, CS-RNTI), interrupt transmission indication RNTI (Interrupted transmission indication RNTI, INT-RNTI), time slot format indication RNTI ( Slot Format Indication RNTI, SFI-RNTI), Semi-Persistent Channel State Information Radio Network Temporary Identity, SP-CSI-RNTI), Transmission Power Control Physical Uplink Control Channel RNTI (Transmit Power Control Physical Uplink Control Channel RNTI, TPC-PUCCH-RNTI), Transmit Power Control Physical Uplink Shared Channel RNTI (Transmit Power Control Physical Uplink Shared Channel RNTI, TPC-PUSCH-RNTI), Transmit Power Control Sounding Reference Signal RNTI (Transmit Power Control Sounding) Reference Signal RNTI, TPC-SRS-RNTI) and artificial intelligence RNTI (Artificial Intelligence RNTI, AI-RNTI), the UE will perform corresponding DRX operations according to the control information. The network controls the UE's DRX behavior by configuring a series of parameters, including:

DRX Duration Timer (drx-onDurationTimer), DRX Slot Offset (drx-SlotOffset), DRX Deactivation Timer (drx-InactivityTimer), Downlink DRX Retransmission Timer (drx-RetransmissionTimerDL), Uplink DRX Retransmission Timer (drx-RetransmissionTimerUL), DRX long cycle start offset (drx-LongCycleStartOffset), DRX short cycle (drx-ShortCycle) parameters (optional): short DRX cycle (the Short DRX cycle), DRX short cycle timer ( drx-ShortCycleTimer) (optional), Downlink HARQ Round Trip Time Timer (Downlink HARQ Round Trip Time Timer, HARQ-RTT-TimerDL), Uplink DRX HARQ RTT Timer (Uplink DRX HARQ RTT, drx-HARQ-RTT- TimerUL), power saving wakeup (Power Saving Wakeup, ps-Wakeup) (optional), power saving transmission of other periodic channel state information (Power Saving Transmit Other Periodic Channel State Information, ps-TransmitOtherPeriodicCSI) (optional), power saving transmission Periodic layer 1 reference signal received power (Power Saving Transmit Periodic L1 Reference Signal Received Power, ps-TransmitPeriodicL1-RSRP) (optional).

Among them, the UE will be in the DRX active state in the following cases:

During the operation of drx-onDurationTimer or drx-InactivityTimer;

During operation of drx-RetransmissionTimerDL or drx-RetransmissionTimerUL;

During the operation of the random access contention resolution timer (ra-ContentionResolutionTimer) or the message B response window (msgB-ResponseWindow);

There are unprocessed scheduling requests (Scheduling Request, SR);

The PDCCH indicates that there is a new transmission period.

In order to facilitate a better understanding of the embodiments of the present application, the technical problems solved by the present application are described.

In the mode 1 (mode 1) mechanism, the network does not know which target address the sideline authorization resource sent to the originating device is used to transmit data, so the network cannot know the DRX inactivity timer (drx-InactivityTimer) of multiple target addresses. ) or the running status of the DRX retransmission timer (drx-RetransmissionTimer), but cannot accurately determine the reasonable sidelink grant time.

Based on the above problems, the present application proposes a solution for sideline communication. The network device can configure reasonable sideline authorization resources, thereby optimizing the sideline communication.
