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 to which an embodiment of the present application is applied. 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 . Specifically, the base station 110 may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal.

FIG. 2 is a schematic diagram of another communication system to which the embodiments of the present application are applicable. The vehicle-mounted terminals (the vehicle-mounted terminal 131 and the vehicle-mounted terminal 132 ) independently select transmission resources for data transmission on the resources of the side link. Optionally, the in-vehicle terminal may randomly select transmission resources, or select transmission resources by means of listening.

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 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 system design requires the terminal equipment to perform continuous transmission and reception.

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 can also define 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.

Different from LTE V2X, in addition to the hybrid automatic repeat request (HARQ) retransmission initiated by the UE without feedback, NR V2X introduces feedback-based HARQ retransmission, which is not limited to unicast communication, but can also include Multicast 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.

To facilitate a better understanding of the embodiments of the present application, the resource selection manner in Mode 2 is described. In NR-V2X, some new features are introduced, such as support for a large number of aperiodic services, an increase in the number of retransmissions, and a more flexible resource reservation period. All of these features have a great influence on the mode of autonomous resource selection of terminal equipment. Therefore, based on Mode 4 in LTE-V2X, a resource selection scheme suitable for NR-V2X is re-discussed and designed, which is denoted as Mode 2. In mode 2, the UE selects the resource pool that is not reserved by other UEs or reserved by other UEs but is not reserved by other UEs by decoding the Sidelink Control Information (SCI) sent by other UEs and measuring the received power of the sidelinks. Receive resources with lower power. The resource selection algorithm of NR-V2X mode 2 may include two main steps, that is, the UE first determines a candidate resource set, and then selects resources from the candidate resource set to send data.

Step 1: The UE determines a candidate resource set.

Specifically, the UE takes all available resources in the resource selection window as the resource set A. First, the UE determines whether the resource is reserved by other UEs according to the listening result in the resource listening window. The UE performs resource exclusion according to the unlistened time slot and the first-order SCI heard. After completing the resource exclusion, if the number of remaining resources in the resource set A is less than a certain proportion, the UE increases the RSRP threshold by 3dB, and repeats the steps. 1 until the number of remaining resources in resource set A is greater than or equal to this ratio. Compared with the fixed ratio of 20% in LTE-V2X, the value of this ratio in NR-V2X is more flexible, and its possible values are {20, 35, 50}%, etc. The specific ratio is based on resource Pools are configured or preconfigured by the network in units. Finally, the resource set A after resource exclusion is the candidate resource set of the UE.

Step 2: The UE selects a transmission resource from the candidate resource set.

The UE randomly selects one or more transmission resources in resource set A with moderate probability.

It should be noted that, when the UE selects the multiple transmission resources, the following restrictions in the time domain must be satisfied:

First, after some exceptions, the UE shall enable the selected certain retransmission resource to be indicated by the previously sent first order SCI. The above exceptions include at least one of the following:

After the UE performs resource exclusion, it cannot select a resource that satisfies the time domain restriction from the resource set A;

Due to factors such as resource preemption, congestion control, and conflict with uplink services, the UE abandons transmission, so that the transmission resources of a certain retransmission are not indicated by the first-order SCI sent previously.

Second, the UE should ensure any two selected time-frequency resources. If the previous transmission resource among them requires HARQ feedback, the two resources are separated by at least Z in the time domain. When the resource selection cannot meet the time domain restriction, such as when the PDB is short but the number of retransmissions is large, depending on the implementation of the UE, the selection of some retransmission resources may be abandoned or the HARQ feedback may be deactivated for certain transmissions.

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.

As mentioned above, the UE can perform the corresponding DRX behavior according to the DRX configuration of the network equipment. During the sidelink transmission, the terminal equipment also needs to save power. In this case, how to implement DRX on the sidelink is an urgent need. solved problem.

FIG. 3 is a schematic interaction diagram of a method for wireless communication according to an embodiment of the present application. As shown in FIG. 3 , the method 300 may include at least some of the following contents:

S310: The terminal device receives a DRX configuration of the network device, where the DRX configuration is used to configure at least one DRX parameter.

In this embodiment of the present application, the at least one DRX parameter may include any DRX parameter used for sideline discontinuous transmission.

In some embodiments of the present application, the at least one DRX parameter includes at least one of the following:

DRX cycle, DRX offset, DRX counter.

Optionally, the DRX offset may be an offset relative to a start position of a DRX cycle, such as a slot offset, a time offset, or a symbol offset, and the like.

In some embodiments, the DRX cycle includes at least one of the following: DRX short cycle, DRX long cycle.

In some embodiments, the DRX offset includes at least one of the following: DRX long cycle start offset, DRX short cycle start offset.

In some embodiments, the DRX timer includes at least one of the following:

Further, as shown in FIG. 3, the method 300 further includes:

S320, the terminal device determines the target resource corresponding to the at least one DRX parameter according to the type of the resource in the resource pool;

S330: Perform lateral transmission according to the target resource corresponding to the at least one DRX parameter.

In some embodiments of the present application, the resource pool may be a resource pool configured by a network device, or a preconfigured resource pool.

In some embodiments, the types of resources in the resource pool may include, but are not limited to, at least one of the following:

A resource that can be used to transmit sideline data, for example, it can carry a Physical Sidelink Shared Channel (PSSCH) or a Physical Sidelink Control Channel (PSCCH);

Resources used for sideline physical sidelink broadcast channel (Physical Sidelink Broadcast Channel, PSBCH) transmission;

resources that cannot be used to carry PSSCH;

resources that cannot be used to carry PSCCH;

Resources that cannot be used for sideline transmission, such as reserved frames, uplink subframes (UL subframes), etc.

Therefore, the resources in the resource pool may include resources that cannot be used to transmit sideline data, denoted as the first type of resources, and resources that can be used to transmit sideline data, such as resources that can carry PSSCH or PSCCH.

Optionally, the resources of the first type may include time-domain resources of the first type, such as subframes (subframes), time slots or symbols, which are not limited in this application.

The specific implementation of determining the target resource corresponding to the DRX parameter according to the resource type is described below with reference to specific embodiments.

Example 1:

Optionally, in this embodiment 1, the S320 may include:

When determining the target resource corresponding to at least one DRX parameter, the terminal device does not exclude the first type of resource in the resource pool.

For example, when determining the target resource corresponding to the DRX parameter, if the resource of the first type is encountered, the terminal device may include the resource of the first type into the target resource corresponding to the DRX parameter.

In some embodiments, the terminal device does not exclude the first type of resources in the resource pool when determining the target resource corresponding to at least one DRX parameter, including:

Determine the candidate resource corresponding to the first DRX parameter according to the first DRX parameter;

If the candidate resource corresponding to the first DRX parameter includes the resource of the first type, the terminal device determines that the target resource corresponding to the first DRX parameter includes the resource of the first type.

With reference to the example in FIG. 4 , if the target count value corresponding to the first DRX parameter is 10, that is, starting from the starting position corresponding to the first DRX parameter, 10 time units need to be counted to obtain the candidate resources of the first DRX parameter. , if the candidate resources of the first DRX parameter include resources of the first type, the resources of the first type are counted, that is, the target resources of the first DRX parameter may include the resources of the first type.

It should be understood that the counting manner in FIG. 4 is only an example, and in other embodiments, the countdown may also start from 10, which is not limited in this application.

It should be understood that in the following examples, only the time unit is a subframe and a time slot as an example for description, but the application is not limited to this, which can be flexibly adjusted according to actual needs or the function of the DRX parameter, which is not made in this application. limited.

As an example, the first DRX parameter includes the length of the DRX cycle, and the determining the candidate resource corresponding to the first DRX parameter according to the first DRX parameter may include:

Starting from the starting position of the DRX cycle, the resource of the length of the DRX cycle is determined as the candidate resource corresponding to the DRX cycle.

Further, if the candidate resource corresponding to the DRX cycle includes the resource of the first type, the terminal device includes the resource of the first type into the target resource corresponding to the DRX cycle. That is, when determining the DRX cycle, the terminal device counts the resources of the first type. In this case, the target resource of the DRX cycle may include the resource of the first type.

For example, if the starting position of the DRX cycle is subframe 2 and the length is 10 subframes, the resources from subframe 2 to subframe 11 are the candidate resources corresponding to the DRX cycle. If subframe 4 is the first type of resource, then The target resources corresponding to the DRX cycle may include resources from subframe 2 to subframe 11.

As another example, the first DRX parameter includes a DRX offset, and the determining the candidate resource corresponding to the first DRX parameter according to the first DRX parameter may include:

From the starting position of the DRX cycle, the resource whose length is the DRX offset is determined as the candidate resource corresponding to the DRX offset.

Further, if the candidate resource corresponding to the DRX offset includes the resource of the first type, the terminal device includes the resource of the first type into the count value of the DRX offset. That is, when the terminal device counts the DRX offset, it can count the resources of the first type. In this case, the target resource of the DRX offset may include the resource of the first type.

For example, if the starting position of the DRX cycle is time slot 0 and the DRX offset is 2 time slots, the resources of time slot 0 and time slot 1 are the candidate resources corresponding to the DRX offset. If the resource of the first type is used, the target resource corresponding to the DRX offset may include resources of time slot 0 and time slot 1.

As yet another example, the first DRX parameter includes a DRX counter, and the determining the candidate resource corresponding to the first DRX parameter according to the first DRX parameter may include:

Starting from the start time of the DRX counter, the resource between the stop time of the DRX counter is determined as the candidate resource corresponding to the DRX counter.

It should be understood that, in the embodiment of the present application, the start condition and the stop condition of the DRX counter are designed according to the function of the timer, which is not limited in the present application.

In some embodiments, if the candidate resource corresponding to the DRX counter includes the resource of the first type, the terminal device counts the resource of the first type into the count value of the DRX counter. That is, when the terminal device counts the DRX counter, it counts the resources of the first type.

For example, if the count value of the DRX counter is 8, the unit is time slot, and the start time of the DRX counter is time slot 2, the resources from time slot 2 to time slot 9 are the candidate resources corresponding to the DRX counter. If time slot 6 includes resources of the first type, the target resource corresponding to the DRX counter may include resources from time slot 2 to time slot 9 .

Further, in the case of counting the resources of the first type, the S330 may include:

The terminal device does not perform lateral transmission and/or lateral reception on the resource of the first type on the target resource.

For example, if the running period of the DRX persistence timer includes the resources of the first type, the terminal device does not perform lateral transmission and/or lateral transmission on the resources of the first type during the running period of the DRX persistence timer. take over.

Further, in some embodiments, the terminal device may perform lateral transmission and/or lateral reception on available resources after the first type of resources on the target resource, so as to ensure that the terminal device can Delay requirements for line transmission. Optionally, the available resources may refer to resources available for transmitting sideline data, such as resources capable of carrying PSSCH or PSCCH. As an example, the available resource may be the first available resource after the first type of resource. For example, the terminal device may send sidelink data on the first available subframe after the first type of resource, or perform sidelink data on the first available subframe after the first type of resource data reception.

Optionally, in Embodiment 1, the resource pool may include one or more resource pools configured on a terminal device, or may also include all resource pools configured on the terminal device.

Optionally, the first type of resources is established for at least one resource pool, for example, one or all resource pools configured on the terminal device.

Example 2

Optionally, in Embodiment 2, the S320 may include:

When determining the target resource corresponding to at least one DRX parameter, the terminal device excludes the first type of resource in the resource pool.

For example, when determining the target resource corresponding to the DRX parameter, if the resource of the first type is encountered, the terminal device does not include the resource of the first type into the target resource corresponding to the DRX parameter.

In some embodiments, when determining the target resource corresponding to at least one DRX parameter, the terminal device excludes the first type of resources in the resource pool, including:

If the candidate resource corresponding to the first DRX parameter includes the resource of the first type, the terminal device determines that the target resource corresponding to the first DRX parameter does not include the resource of the first type.

With reference to the example in FIG. 5 , if the target count value corresponding to the first DRX parameter is 10, that is, starting from the starting position corresponding to the first DRX parameter, 10 time units need to be counted to obtain the candidate for the first DRX parameter. Resource, if the candidate resource of the first DRX parameter includes the resource of the first type, the resource of the first type is not counted, that is, the counting is suspended, or in other words, the resource of the first type is skipped and counted again. In this case, The target resource corresponding to the first DRX parameter does not include the resource of the first type.

It should be understood that the counting manner in FIG. 5 is only an example, and in other embodiments, the countdown may also start from 10, which is not limited in this application.

Further, if the candidate resource corresponding to the DRX cycle includes the resource of the first type, the terminal device does not include the resource of the first type into the target resource corresponding to the DRX cycle. That is, when the terminal device determines the DRX cycle, it does not count the resources of the first type. In this case, the target resource of the DRX cycle does not include the resource of the first type.

For example, if the starting position of the DRX cycle is subframe 2 and the length is 10 subframes, the resources from subframe 2 to subframe 11 are the candidate resources corresponding to the DRX cycle. If subframe 4 is the first type of resource, then The target resources corresponding to the DRX cycle may include resources from subframe 2 to subframe 12, and do not include resources in subframe 4.

Further, if the candidate resource corresponding to the DRX offset includes the resource of the first type, the terminal device does not include the resource of the first type into the count value of the DRX offset. That is, when the terminal device counts the DRX offset, it does not count the resources of the first type. In this case, the target resource of the DRX offset does not include the resource of the first type.

For example, if the starting position of the DRX cycle is time slot 0 and the DRX offset is 2 time slots, the resources of time slot 0 and time slot 1 are the candidate resources corresponding to the DRX offset. If the resource of the first type is used, the target resource corresponding to the DRX offset may include the resources of time slot 0 and time slot 2.

In some embodiments, if the candidate resource corresponding to the DRX counter includes the resource of the first type, the terminal device does not count the resource of the first type into the count value of the DRX counter. That is, when the terminal device counts the DRX counter, it does not count the resources of the first type.

For example, if the count value of the DRX counter is 8, the unit is time slot, and the start time of the DRX counter is time slot 2, the resources from time slot 2 to time slot 9 are the candidate resources corresponding to the DRX counter. If time slot 6 is the resource of the first type, the target resource corresponding to the DRX counter may include resources from time slot 2 to time slot 10 and does not include time slot 6 .

Further, in the case of not counting the resources of the first type, the S330 may include:

The terminal device performs lateral transmission and/or lateral reception on the target resource.

Optionally, in Embodiment 2, the resource pool may include one or more resource pools configured on a terminal device, or may also include all resource pools configured on the terminal device.

Therefore, in this embodiment 2, when determining the target resources corresponding to the DRX parameters, the first type of resources in the resource pool is not counted, that is, the determined target resources corresponding to the DRX parameters are all resources that can be used to transmit sideline data , which is conducive to ensuring the number of target resources (or effective resources) corresponding to the DRX parameters. In this way, when performing sideline transmission, the target resources corresponding to the DRX parameters can be directly used for sideline transmission, which is conducive to satisfying the sideline transmission. need.

To sum up, the terminal device determines the target resource corresponding to the DRX parameter according to the resource type in the resource pool, and further performs sidelink transmission based on the target resource corresponding to the DRX parameter, which can control the DRX behavior on the sidelink, which is beneficial to Meet the power saving needs of the terminal.
