In order to facilitate understanding of the embodiments of the present application, the basic processes and basic concepts involved in the embodiments of the present application are briefly described below. It should be understood that the basic processes and basic concepts introduced below do not limit the embodiments of the present application.

Device-to-device communication is a side link transmission technology (SL: Sidelink) based on D2D. Different from the traditional cellular system in which communication data is received or sent through the base station, the Internet of Vehicles system adopts terminal-to-device communication. The terminal communicates directly, so it has higher spectrum efficiency and lower transmission delay. There are two transmission modes defined in 3GPP: Mode A and Mode B. Mode A, as shown in Figure 2a, the transmission resources of the terminal device are allocated by the network device 210. The terminal device (terminal device 211 and terminal device 212 in Figure 2a) transmits data on the sidelink according to the resources allocated by the network device 210. To send data; the network device can allocate resources for a single transmission to the terminal, or allocate resources for semi-static transmission to the terminal device. In Figure 2a, a two-way solid arrow is used to represent the side link between the terminal device 211 and the terminal device 212; in Figure 2a, a dotted arrow is used to represent the resource usage of the network device 210 allocating transmission to the terminal device 211 (or the terminal device 212). downlink. Mode B, as shown in Figure 2b, the terminal device, specifically a vehicle-mounted terminal, selects a resource in the resource pool for data transmission. In Figure 2b, a two-way solid line arrow is used to represent the side link between the terminal device 221 and the terminal device 222. As can be seen in Figure 2b, the network device 220 does not allocate transmission information to the terminal device 221 or the terminal device 222. resource.

In the 3rd Generation Partnership Project (3GPP), D2D is divided into different stages for research: ProSe (Proximity based Service): mainly aimed at public safety services; in ProSe, by configuring resource pools The position in the time domain, for example, the resource pool is non-continuous in the time domain, so that the terminal device can send/receive data non-continuously on the sidelink, thereby achieving the effect of power saving. Internet of Vehicles (V2X): Mainly oriented to relatively high-speed vehicle-to-vehicle and vehicle-to-human communication services; in V2X, since the vehicle system has continuous power supply, the delay of data transmission is the main problem, and the system design requires terminal equipment Perform continuous sending and receiving. Wearable devices (FeD2D): Mainly oriented to low mobile speed and low power access scenarios; in FeD2D, during the pre-research stage 3GPP concluded that network equipment can be configured remotely through a relay terminal DRX (Discontinuous Reception, discontinuous reception) parameters of the terminal, but since this topic has not further entered the standardization stage, there is no conclusion on the specific details of how to configure DRX.

Based on LTE V2X, NR V2X is not limited to broadcast scenarios, but further extends to unicast and multicast scenarios, and the application of V2X is studied in these scenarios. Similar to LTE V2X, NR V2X will also define the above two resource authorization modes mode-1/2; further, the terminal device may be in a mixed mode, that is, it can use mode-1 to obtain resources, and at the same time You can use mode-2 to obtain resources. The resource acquisition is indicated through sidelink grant, that is, the sidelink grant indicates the time-frequency location of the corresponding PSCCH and PSSCH resources. Different from LTE V2X, in addition to HARQ retransmission without feedback and independently initiated by the terminal device, NR V2X introduces feedback-based HARQ retransmission, which is not limited to unicast communication, but also includes multicast communication.

Carrier selection in LTE-V2X carrier aggregation is completed by the following mechanism: the upper layer configures the mapping relationship between service type (service type) and carrier, that is, for a certain service, the upper layer indicates the available carriers (set) to the AS layer; further, the AS The layer configures the set of carriers available for each logical channel and the CBR measurement threshold configured for data priority (priority) in each resource pool. The UE measures the CBR value in the resource pool and compares it with the CBR threshold corresponding to the priority of the transmitted data. If the measured value is lower than the threshold, the carrier is considered available.

Both LTE V2X and NR V2X support CBR/Channel Occupancy Ratio (CR, Channel Occupancy Ratio) measurement, which is mainly used for congestion control in terminal autonomous resource selection mode. The definitions of CBR/CR for LTE V2X and NR V2X are basically the same, except that NR V2X has some differences in parameter values due to its support of multi-subcarrier spacing. The definition of CBR is: the proportion of sub-channels with SL RSSI higher than the configured threshold in the CBR measurement window to the total number of sub-channels in the resource pool, which is equal to 100 sidelink subframes in LTE V2X, and equals to NR V2X based on the parameters configured by the higher layer. 100ms or 100·2 ^μ sidelink time slots. It should be noted that in LTE V2X, since PSSCH and PSCCH may not be adjacent, the corresponding resource pools are configured separately. At this time, CBR measurement can be performed in both the resource pools where PSSCH and PSCCH are located. In NR V2X, the PSCCH and the indicated PSSCH occupy the same resource pool, so CBR measurement does not differentiate based on PSSCH and PSCCH.

Carrier Aggregation (CA) can aggregate multiple component carriers (CC) together and be received or transmitted by a terminal device at the same time. According to the range of aggregated carriers, CA can be divided into intra-band CA (intra-band CA) and cross-band CA (inter-band CA). One of the main uses of Intra-band CA is in scenarios where the cell carrier bandwidth is greater than the single carrier bandwidth capability of the terminal device. In this case, the terminal device can use CA to operate in a "wide carrier" . For example, the network equipment supports a carrier of 300MHz, but the terminal equipment only supports a maximum carrier of 100MHz. At this time, the terminal equipment can use CA mode to achieve broadband operation greater than 100MHz. The aggregated carriers can be adjacent carriers or non-adjacent carriers. carrier.

When terminal equipment and network equipment communicate through Carrier Aggregation (CA), the primary cell and secondary cell (SCell) may be configured at the same time. A beam failure recovery mechanism is designed for the primary cell (PCell) and the secondary primary cell (PSCell). Its main functional modules (or main steps) are divided into 4: Beam Failure Detection (BFD); New beam selection (New Beam Identification, NBI); Beam Failure Recovery ReQest (BFRQ); Network side response. Specifically, the terminal equipment measures the PDCCH (Physical Downlink Control Channel) to determine the link quality corresponding to the downlink transmission beam; if the corresponding link quality is very poor, the downlink beam fails; the terminal equipment A group of candidate beams are measured, and the beam that meets the threshold is selected as a new beam; the terminal device notifies the network of a beam failure through BFRQ information and reports a new beam. After receiving the BFRQ information sent by a terminal device, the network device determines that a beam failure has occurred in the terminal device, and selects to send the PDCCH on a new beam. When the terminal device receives the PDCCH sent by the network device on the new beam, it is determined that the response information from the network side has been correctly received. At this point, the beam failure recovery process is successfully completed.

Sidelink transmission discontinuous reception (DRX, Discontinuous Reception) configuration and terminal behavior: The MAC entity can be configured by RRC (Radio Resource Control) to have the SL (Sidelink, sidelink) DRX function, which controls the UE The SCI (Sidelink Control Information) (i.e., Phase 1 SCI and Phase 2 SCI) monitors activities for unicast, multicast, and broadcast. When operating using SL DRX, the MAC entity shall also monitor SCI (i.e., Phase 1 SCI and Phase 2 SCI) in accordance with the requirements in other provisions of this specification. RRC controls Sidelink DRX operation by configuring the following parameters:

sl-drx-onDurationTimer (sidelink DRX activation timer): the duration of the start of an SL DRX cycle;

-sl-drx-SlotOffset (sidelink DRX slot offset): delay before starting sl-drx-onDurationTimer;

-sl-drx-InactivityTimer (sidelink DRX inactivity timer) (except broadcast transmission): the duration after reception of the first slot of SCI (i.e., first-stage SCI and second-stage SCI), where SCI Indicates new SL transmission for the MAC entity;

-sl-drx-RetransmissionTimer (retransmission timer for sidelink DRX) (per Sidelink process except broadcast transmission): Maximum duration until SL retransmission is received;

-sl-drx-StartOffset (sidelink DRX start offset): the slot where the SL DRX cycle starts;

-sl-drx-Cycle (sidelink DRX cycle): Sidelink DRX cycle;

-sl-drx-HARQ (Hybrid Automatic Repeat reQuest)-RTT (Round-Trip Time)-Timer (per Sidelink process except broadcast transmission): MAC entity expects SL HARQ retransmission The previous minimum duration.

When configuring SL DRX, activity time includes the following times: sl-drx-onDurationTimer or sl-drx-InactivityTimer is running; or, sl-drx-RetransmissionTimer is running; or, when no SL-CSI report MAC CE is received , the sl-LatencyBound (delay bound) CSI (channel state information)-Report (report) cycle configured by RRC; or, in the case of receiving the SL-CSI report MAC CE, from sending the SL-CSI report request to receiving The time between SL-SCI reporting MAC CEs; alternatively, the time slot associated with periodic transmissions announced by the UE sending SL-SCH data.

When configuring one or more SL DRXs, the MAC entity shall:

1> If multiple SL-QoS-Profiles associated with multicast and broadcast have target Layer 2 (L2) IDs (identifications) and multiple SL DRX cycles for the broadcast type mapping of interest:

2>Select the sl-drx-Cycle with the shortest sl-drx-cycle length among multiple SL DRX Cycles mapped to multiple SL-QoS-Profiles associated with the target layer 2 (L2) ID:

3>After sl-drx-HARQ-RTT-Timer expires, start sl-drx-RetransmissionTimer in the Sidelink process corresponding to the first slot.

When the broadcast type is multicast or broadcast as indicated by the upper layer, sl-drx-StartOffset and sl-drx-SlotOffset are derived from the following equation:

sl-drx-StartOffset(ms)=target layer 2 (L2) ID modulo sl-drx-Cycle(ms).

sl-drx-SlotOffset(ms)=target layer 2 (L2) ID modulo sl-drx-onDurationTimer(ms).

1>If SL DRX cycle is used, and [(DFN×10)+subframe number] modulo (sl-drx-Cycle)=sl-drx-StartOffset:

2>Start sl-drx-onDurationTimer after sl-drx-SlotOffset starting from subframe.

4>Start sl-drx-HARQ-RTT-Timer for the corresponding Sidelink process in the time slot after the end of PSSCH transmission (that is, the currently received PSSCH).

3>If PSFCH resources are configured for the SL authorization associated with SCI:

4>If SCI enables HARQ feedback and the cast type indicator in SCI is set to unicast; or

4>If SCI enables HARQ feedback and the cast type indicator in SCI is set to groupcast and positive and negative confirmation is selected;

5>In the first time slot after the corresponding PSFCH transmission carrying SL HARQ feedback ends, start the sl-drx-HARQ-RTT-Timer corresponding to the Sidelink process; or

5> When SL HARQ feedback is not sent due to UL/SL prioritization, start the sl-drx-HARQ-RTT-Timer of the corresponding Sidelink process in the first time slot after the end of the corresponding PSFCH resource of SL HARQ feedback;

5>Start sl-drx-HARQ-RTT-Timer for the corresponding Sidelink process in the time slot after the PSSCH transmission (that is, the currently received PSSCH) ends.

Note: When the SCI indicates the next retransmission resource, the sl-drx-HARQ-RTT-Timer is derived from the retransmission resource timing (i.e., the next retransmission resource indicated in the SCI). When the SCI does not indicate the next retransmission resource, the UE uses sl-drx-HARQ-RTT-Timer to configure according to the regulations in TS 38.331[5].

In some possible implementations, the first terminal determines to use the first listening duration and the second listening duration to conduct side link monitoring during the listening period; or, the first terminal determines to use the second listening duration to conduct side link monitoring during the listening period. Line link monitoring. That is, the first terminal keeps using the second listening duration to perform sidelink monitoring during the monitoring period, but will further determine whether to increase the second listening duration to perform sidelink monitoring.

The first terminal first needs to determine the first listening duration and the second listening duration.

Optionally, the method further includes: the first terminal receiving first information, the first information including: configuration information of a first timer, and the configuration information of the first timer is used to determine the The startup duration of the first timer; wherein the startup duration of the first timer is equal to the first listening duration.

The first information may be configured by the network device, configured by the second terminal, or preset.

Wherein, when the first information is network device configuration, the first information is carried by one of the following: RRC message, system message, MAC CE, downlink control information DCI. Alternatively, in the case where the first information is configured by the second terminal, the first information may be carried by one of: sidelink MAC CE, SCI, and sidelink RRC messages.

If the second timer is the activation timer of the sidelink DRX, the first timer may be called the new activation timer of the sidelink DRX (sl-drx-new-onDurationTimer); it should be understood that here only is a possible name for the first timer. In actual processing, as long as the first timer's startup duration is used for the first terminal to control a new startup duration in addition to the second timer's startup duration, It is within the protection scope of this embodiment. If the second timer is the retransmission timer of the sidelink DRX, the first timer may be called the new retransmission timer of the sidelink DRX (sl-drx-new-RetransmissionTimer); it should be understood that here It is also only a possible name. In actual processing, as long as the startup duration of the first timer is a new startup duration in addition to the startup duration of the second timer, it is within the protection scope of this embodiment. .

Specifically, the first terminal uses the first listening duration and/or the second listening duration to perform sidelink monitoring during the monitoring period, including:

When the first terminal performs sidelink monitoring within the starting duration of the second timer of the monitoring cycle, if the first condition is met, all the processes are started at the first moment of the monitoring cycle. The first timer performs sidelink monitoring within the startup duration of the first timer; and/or the first terminal performs sidelink monitoring within the startup duration of the second timer of the listening period. During the sidelink monitoring process, if the first condition is not met, the sidelink monitoring of the monitoring period ends at the end of the start duration of the second timer.

The aforementioned first moment may refer to the moment when or after the start duration of the second timer ends. That is to say, after the first terminal receives the aforementioned first information and second information, it can determine whether to extend the listening duration in each listening period. For example, when the first terminal uses the second listening duration (i.e., the starting duration of the second timer) to monitor the sidelink during the listening period, it determines whether the first condition is met, and if so, determines to extend the listening duration. , when or after the end of the second listening duration in the listening period, start sidelink monitoring within the first listening duration (starting duration of the first timer); if the first condition is not met, it is determined not to To extend the listening period, the first terminal determines to end monitoring of the sidelink in the listening period when the second listening period (ie, the start time of the second timer) ends in the listening period. After completing the foregoing processing, the first terminal can enter the next listening cycle and adopt the same processing as mentioned above, without repeated explanation.

In this embodiment, unless otherwise specified, the starting duration of the first timer has the same definition as the first listening duration, and the starting duration of the second timer has the same definition as the second listening duration, and the description will not be repeated.

The first listening duration and the second listening duration may be the same or different, but the starting times corresponding to the first listening duration and the second listening duration are different. That is, the starting time or starting time of the first timer and the second timer are different.

The start time of the second timer may be specified by the protocol. For example, the second timer is sl-drx-onDurationTimer, and its start time can be determined by: when the broadcast type is multicast or broadcast, if the SL DRX cycle is used, and [(DFN×10)+subframe number] Modulo (sl-drx-Cycle)=sl-drx-StartOffset, then sl-drx-onDurationTimer is started after sl-drx-SlotOffset starting from the subframe. Among them, sl-drx-StartOffset and sl-drx-SlotOffset are derived from the following equation: sl-drx-StartOffset(ms) = target layer 2 (L2) ID modulo sl-drx-Cycle(ms); sl-drx- SlotOffset(ms)=target layer 2 (L2) ID modulo sl-drx-onDurationTimer(ms).

For another example, the second timer is sl-drx-RetransmissionTimer, and the method of determining its start time may include: if the sl-drx-HARQ-RTT-Timer expires and the data of the corresponding side link process is not successfully decoded, then After the sl-drx-HARQ-RTT-Timer expires, the sl-drx-RetransmissionTimer is started in the sidelink process corresponding to the first time slot. Alternatively, if the sl-drx-HARQ-RTT-Timer expires and no HARQ feedback is transmitted for unicast due to UL/SL priority (i.e. negative acknowledgment), then after the sl-drx-HARQ-RTT-Timer expires, The sidelink process corresponding to the first time slot starts sl-drx-RetransmissionTimer.

The start time of the first timer is the first time, and the first time is related to the end time of the start duration of the second timer. The aforementioned first time refers to the relative time in the listening period.

Optionally, the first time is the end time of the start duration of the second timer. For example, see Figure 4. After the second timer is turned on in the first listening cycle, sidelink monitoring is performed for the start time of the second timer. If the first condition is not met, the first timer is not turned on in the first listening cycle. The timer determines to end the sidelink monitoring in the first listening period at the end of the start duration of the second timer. After starting the second timer in the second listening cycle, the start duration of the second timer is entered for sidelink link monitoring. If the first condition is met, the end time of the start duration of the second timer in the second listening cycle is As the aforementioned first moment, the first timer is started at the first moment, the start time of the first timer is entered to perform side link monitoring, and at the end time of the start time of the first timer, it is determined to end the second monitoring Sidelink monitoring during the cycle.

It should be understood that the startup duration of the first timer should be less than the period duration of the sidelink DRX minus the startup duration of the second timer, and then minus the sidelink DRX time slot offset.

Optionally, the first time is after the end time of the start duration of the second timer, and there is a time domain offset from the end time of the start duration of the second timer. Wherein, the time domain offset is preset, or determined by the first terminal, or configured by the network device, or configured by the second terminal.

That is, in the listening period, the first terminal delays the end time of the start duration of the second timer to the time after the time domain offset as the first time, starts the first timer at the first time, and enters the first time. The start duration of the timer is the first listening duration. For example, see Figure 5. After the second timer is turned on in the first listening cycle, sidelink monitoring is performed for the start time of the second timer. If the first condition is not met, the first timer is not turned on in the first listening cycle. The timer determines to end the sidelink monitoring in the first listening period at the end of the start duration of the second timer. After starting the second timer in the second listening cycle, the start duration of the second timer is entered for sidelink link monitoring. If the first condition is met, the end time of the start duration of the second timer in the second listening cycle is The time after the delay time domain offset is used as the aforementioned first time. At this first time, the first timer is started, and the side link monitoring is performed during the start time of the first timer. At the end of the start time of the first timer, time, it is determined to end the sidelink monitoring in the second listening cycle.

It should be understood that the start time of the first timer should be less than the cycle time of the sidelink DRX minus the start time of the second timer, minus the time slot offset of the sidelink DRX, and subtract the aforementioned time domain offset.

The first condition includes at least one of the following: the inactivation timer is not started; the first indication information is not received; the second indication information is received.

Wherein, the first terminal may determine whether the first condition is met during the sidelink monitoring using the second listening duration (i.e., the starting duration of the second timer), and then use the second listening duration (i.e., the second timer startup duration) to determine whether the first condition is met. When the sidelink monitoring is completed (the start time of the timer), it is judged whether the first condition is met. For example, the aforementioned second indication information may be obtained within the start-up time of the second timer. When the second indication information is received, it can be determined that the first condition is met. Alternatively, monitoring can be maintained during the start-up period of the second timer, and when the start-up period of the second timer ends, it is judged whether the aforementioned first condition is met, and the judgment result is obtained.

Here, the inactivity timer specifically refers to the inactivation timer (sl-drx-InactivityTimer) of the sidelink DRX. Not starting the inactivation timer may refer to that the first terminal does not start the inactivation timer within the starting time of the second timer in the listening period.

The inactivation timer of the sidelink DRX is the timer specified in the protocol. The method of starting the inactivation timer of the sidelink DRX can be: if the SL DRX is in the active time, the SCI indicates a new SL Transmission, SCI's Source Layer-1 (source layer 1, source L1) ID is equal to the 8 least significant bits (LSB) of the expected target L2 ID and the source L1 ID of the SCI is equal to 8 of the expected source L2 ID LSB, and the mandatory type indicator in the SCI is set to unicast, then after the first SCI reception slot, start or restart sl-drx-InactivityTimer for the corresponding source L2 ID and target L2 ID pair. and/or, if the SL DRX is active, the SCI indicates a new SL transmission, the target L1 ID of the SCI (i.e., the Phase 2 SCI) is equal to 8 LSBs of the expected target L1 ID, and the broadcast type indicator in the SCI is set to For multicast, after the first SCI receiving time slot, start or restart sl-drx-InactivityTimer for the corresponding target L2 ID.

Optionally, when the second timer is an activation timer for sidelink discontinuous reception DRX, the first indication information is sidelink control information SCI used to indicate newly transmitted data; and /Or, the second indication information is used to indicate at least one of the following: listen before sending LBT failure; extended monitoring.

The aforementioned first indication information should be sent by the second terminal to the first terminal. The aforementioned SCI indicating newly transmitted data can be used by the first terminal to determine to start the inactivation timer; therefore, the first terminal has not received the side link control information SCI indicating newly transmitted data, and the aforementioned first terminal has not received the side link control information SCI indicating newly transmitted data. The conditions for starting the inactivation timer are similar. During actual configuration, you can configure both conditions, or only any one of them.

The second indication information may be sent by the second terminal to the first terminal. For example, the second terminal needs to perform LBT before sending new data. If the second terminal fails LBT, it will send the aforementioned second instruction information to the first terminal. The second indication information may be a direct LBT failure indication, or may also be an extended listening indication. In some examples, the instruction to extend listening may be an instruction to start (or start) the first timer.

It should be understood that in this case, the first timer is a new activation timer of the sidelink DRX. The description of the new activation timer of the sidelink DRX is the same as the previous embodiment and will not be repeated.

Optionally, when the second timer is a sidelink retransmission timer, the first indication information is an SCI used to indicate retransmission of data; and/or the second indication information is Extend monitoring on instructions.

The aforementioned first indication information should also be sent by the second terminal to the first terminal. The second indication information may be sent by the second terminal to the first terminal. The second instruction information may directly be an instruction to extend monitoring. In some examples, the instruction to extend listening may be an instruction to start (or start) the first timer.

It should be understood that in this case, the first timer is a new retransmission timer of the sidelink DRX. The description of the new retransmission timer of the sidelink DRX is the same as the previous embodiment and will not be repeated.

It should be noted that, in actual use, all of the aforementioned first conditions may be configured and used, or only at least one of them may be configured and used, which are all within the protection scope of this embodiment and will not be described in detail here.

In some possible examples, the first listening duration includes: one or more first listening durations under the target granularity; the second listening duration includes: one or more second listening durations under the target granularity.

The method further includes: the first terminal receiving third information, where the third information includes: configuration information of each third timer in one or more third timers at a target granularity; wherein, The configuration information of different third timers is used to determine the start duration of different third timers, and different third timers are associated with different objects of the sidelink at the target granularity.

The method further includes: the first terminal receiving fourth information, the fourth information including configuration information of each fourth timer in one or more fourth timers under the target granularity; wherein, The configuration information of different fourth timers is used to determine the start duration of different fourth timers, and the different fourth timers are associated with different objects of the sidelink at the target granularity.

Wherein, the target granularity is one of the following: target address, sidelink quality of service QoS profile, transmission mode, and terminal.

The target address may refer to the target L2 address, and the target address may be related to the service. The first terminal can use the target address as a unit to divide multiple target addresses, and different target addresses are associated with different third timers and different fourth timers. That is to say, the first terminal can be divided based on the target address as a unit, and use the third timer and the fourth timer associated with different target addresses to perform related processing of sidelink monitoring.

The sidelink QoS profile (Profile) can be finer-grained than the aforementioned target address. For example, different sidelink QoS profiles (Profiles) are associated with different third timers and different fourth timers. That is, the first terminal can be divided based on the side link QoS profile (Profile) as a unit, and use the third timer and the fourth timer associated with different side link QoS profiles (Profile) to perform side link Related processing of road monitoring.

The transmission mode may include unicast, multicast, and broadcast, that is, the first terminal may determine which configuration of the third timer and fourth timer is currently used based on the transmission mode used.

The aforementioned target granularity includes terminals. For example, when a first terminal performs sidelink transmission with multiple second terminals, different terminals associated with different third timers and different fourth timers may be determined. That is to say, the first terminal can be divided based on terminal units, and the third timer and the fourth timer associated with different terminals can be used to perform related processing of sidelink monitoring.

It should be noted that after dividing based on the target granularity, one or more objects under the target granularity can be obtained; the object may specifically refer to the object monitored by the first terminal on the side link, or may refer to the object monitored on the side link. The object for signal transmission on the uplink. For example, if the target granularity is a terminal, one or more terminals under the target granularity of the terminal can be divided, and the one or more terminals are one or more objects under the target granularity; for example, if the target granularity is a target address, then one or more terminals can be divided into One or more target addresses under the target granularity of the target address are divided, and the one or more target addresses are one or more objects under the target granularity. No more exhaustiveness here.

The first terminal may maintain different third timers and different fourth timers associated with different objects under the same target granularity at the same moment. For example, assuming that the target granularity is a terminal, and the first terminal performs sidelink communication with three second terminals at the same time, the third timer 1 and the third timer 1 associated with the second terminal 1 under the target granularity of the terminal can be maintained. Four timers 1, the third timer 2 and the fourth timer 2 associated with the second terminal 2, the third timer 3 and the fourth timer 3 associated with the second terminal 3. For example, assuming that the target granularity is a target address, when the first terminal performs sidelink communication with two target addresses at the same time, the third timer 1 and the fourth timer 1 can be maintained to be associated with the target address 1, and the third timer 1 can be associated with the target address 1. Timer 2 and fourth timer 2 are associated with target address 2.

The following describes the processing performed by any object under the target granularity. Any object under the target granularity is called the target object:

The first terminal uses the first listening duration and/or the second listening duration to perform sidelink monitoring during the monitoring period, including:

During the process of monitoring the signal transmitted by the target object on the sidelink within the starting duration of the fourth timer associated with the target object under the target granularity of the listening period, the first terminal satisfies the second requirement. If conditions exist, start a third timer associated with the target object at the first moment of the listening cycle, and monitor the signal transmitted by the target object within the start duration of the third timer associated with the target object; wherein , the startup duration of the fourth timer associated with the target object is equal to the second listening duration, and the startup duration of the third timer associated with the target object is equal to the first listening duration.

And/or, the first terminal is in the process of monitoring the signal transmitted by the target object at the target granularity on the side link within the starting duration of the fourth timer associated with the target object in the listening period. , if the second condition is not met, end the side link monitoring of the listening period at the end of the start duration of the fourth timer associated with the target object.

Alternatively, the fourth timer is a sidelink retransmission timer; and/or the third timer is a sidelink new retransmission timer. .

Wherein, the time domain offset is preset, or determined by the first terminal, or configured by the network device, or configured by the second terminal.

The aforementioned time domain offset can also be configured as one or more time domain offsets, that is, different time domain offsets can be configured for different objects at the target granularity. Correspondingly, the first time may be after the end time of the start duration of the fourth timer associated with the target object, and there is a time domain offset in the end time of the start duration of the fourth timer associated with the target object. shift.

The second condition includes at least one of the following: the inactivation timer associated with the target object is not started; the first indication information associated with the target object is not received; the second indication information associated with the target object is received .

Here, the inactivation timer also refers to the inactivation timer of the sidelink DRX; the only difference from the previous embodiment is that different inactivation timers of the sidelink DRX can be configured for different objects under the target granularity. . For example, the target granularity is the target address, and there are currently two target addresses. Inactivation timer 1 is configured for target address 1, and inactivation timer 2 is configured for target address 2. Correspondingly, during the first terminal's process of monitoring the signal transmitted by the target address 2 on the sidelink within the startup duration of the second second timer of the listening cycle, if the second inactive timer, it is determined that the first condition mentioned above is met. Other descriptions about the inactivation timer are similar to the previous embodiments and will not be described again.

In this embodiment, since signals transmitted by different objects in the target granularity of the sidelink are monitored, the first indication information and the second indication information are also related to different objects in the target granularity. Specifically, in the process of monitoring the signal transmitted by the target object at the target granularity on the sidelink, the first indication information is related to the target object; similarly, the second indication information is related to the target object. related to the target object.

Optionally, when the fourth timer associated with the target object is sidelink discontinuous reception DRX, the first indication information may specifically refer to the first indication information related to the target object, that is, the first indication information is SCI used to indicate the newly transmitted data of the target object at the target granularity.

Other relevant descriptions about the first instruction information and the second instruction information are the same as the foregoing implementation and will not be described again.

It should be understood that in this case, the third timer associated with the target object is the sidelink new retransmission timer, and the description of the new retransmission timer of the sidelink DRX is the same as the previous embodiment. No further details will be given.

In the solution provided in the above embodiments, the first terminal can use the first listening duration and the second listening duration within a listening period, or only use the second listening duration to perform sidelink monitoring. In this way, the first terminal can The terminal may increase the listening time during the listening cycle, thereby reducing the problem of continuous reception failures by the first terminal and increasing the possibility of successfully receiving data.

In some possible implementations, the first terminal uses the first listening duration or the second listening duration to perform sidelink monitoring during the listening period.

That is to say, the first terminal may predetermine to use one of the first listening duration and the second monitoring duration to perform sidelink monitoring during the monitoring period. In this implementation manner, the first listening duration is longer than the second listening duration. In each listening period, the starting moments of the first listening duration and the second listening duration may be the same.
