Description

Transmission configuration method and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a transmission configuration method and a terminal.

Background

In an interface (e.g., a Uu port) between a terminal and a network side device, a user only monitors a Physical Downlink Control Channel (PDCCH) during an activation time, so as to achieve the purpose of saving energy, where the activation time includes a duration (on duration), and an activity timer (activity timer) runs and a retransmission timer (retransmission timer) runs. The Uu DRX does not limit the time of uplink transmission and other downlink transmission of the user, for example, the user may send a Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) to the base station outside the activation time.

A Sidelink (Sidelink, abbreviated as Sidelink, direct communication link, or the like, abbreviated as SL) Semi-Persistent Scheduling (SPS) period may include one or more SL resources, a SL Configuration Grant (CG) period may include one or more SL resources, a SL Downlink Control Information (DCI) for Scheduling SL transmission resources may schedule one or more SL resources, and a Sidelink Control Information (SCI) for Scheduling one or more SL resources that may be reserved for subsequent transmission in a period of time. Each of the above resources may contain SCI, and only part of the resources in the same period or resources scheduled by one DCI or indicated by one SCI may be in the active time, while the other part of the resources are out of the active time. A situation may also occur in which a Physical Sidelink Feedback Channel (PSFCH) corresponding to a resource scheduled by one DCI or indicated by one SCI is outside the activation time in the same period.

If the design of the direct Uu DRX is reused, the user will not receive the SCIs or PSFCHs at this time, resulting in packet loss, low reliability, and low resource utilization.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

In making the description of the embodiments of the present invention, some concepts used in the following description will first be explained.

1. Introduction of Long Term Evolution (LTE) and New Radio (NR) interface between a terminal and a network side device (Uu interface) Discontinuous Reception (DRX)

Both LTE and NR introduce a DRX mechanism to achieve power saving for User Equipment (UE, also called terminal) by configuring DRX on and off times. As shown in fig. 1, the duration (on duration) is a DRX on interval, and if no scheduling is performed, the UE enters an off duration of one DRX cycle (DRX cycle) after the on duration.

2. Introduction to sidelink (translated as sidelink, direct communication link, etc., SL for short)

The sidelink design supports two resource allocation modes, namely a Scheduled resource allocation (Scheduled resource allocation) mode (commonly referred to as mode-1) and an autonomous resource selection (commonly referred to as mode-2). The former is controlled by network side equipment and allocates resources for each UE, and the latter is selected by the UE autonomously. In mode-1, Radio Resource Control (RRC) or Downlink Control Information (DCI) may indicate one or more resources, for example, as shown in fig. 2, for example, Configured periodically-occurring Resource SL Configured grant (SL CG); in mode-2, where a user acquires resources by sensing, one SCI may indicate one or more resources and further may reserve them periodically, for example, as shown in fig. 3. In particular, the terminal selects the resources for its own transmission from the remaining resources by detecting SCI and/or measuring to determine which resources have been occupied by other terminals.

The PSCCH in LTE Sidelink carries SCI, and the PSCCH and PSSCH in NR Sidelink carry part of SCI respectively. SCI is used to schedule the psch. Transmission resources may be indicated in the SCI and further reserved for future transmissions. A Physical Sidelink Feedback Channel (PSFCH) is used for feeding back Sidelink HARQ-ACK information, and after determining the Sidelink HARQ-ACK information, the user may further send the Sidelink HARQ-ACK information to the base station through a PUCCH or a PUSCH.

PSFCH resources

One psch frequency domain occupies N sub-channels (sub-channels), and one PSFCH resource frequency domain occupies only 1 RB, so the number of PSFCH RBs in the same resource pool is much larger than the number of psch bearers.

As shown in fig. 4, a psch resource occupies a sub-channel in the frequency domain, and there are 10 PSFCH RBs in the sub-channel.

PSFCH occast occurs every N slots (sidelink slots), i.e. the period N of PSFCH is 1,2, 4. Thus, some SL slots have PSCCH/PSSCH and PSFCH, and some PSCCH/PSSCH alone have no PSFCH. There are N possible pschacations associated with this pscfh occasion per period, and the pschacession associated with pschacession on slot m is no earlier than m + K, where K is 2, 3.

Note that: the SubCarrier Spacing (SCS) of the above parameters may be the same or different, and K and N are local slots (SL slots), so the actual distance between K SL slots may be greater than the duration corresponding to K physcil slots, and the actual distance between N SL slots may be greater than the duration corresponding to N physcil slots. As shown in FIG. 5, assume that

physical slots

2 and 4 of the 5 physical slots are used for SL, so the local slot numbers or SL slots of the two SL slots are 1 and 2. At this time, the actual distance between

local slots

1 and 2 is 2physical slots, which is longer than the duration corresponding to 1 slot.

Cast type and HARQ feedback mode

Three transmission modes of broadcast, multicast and unicast are supported in NR sidelink. The NR sidelink multicast supports two use cases of connection-based multicast and connectionless multicast, the connection-based multicast means that connection is established between multicast UEs, and the connectionless mode means that the multicast UEs do not know other UEs in the group and do not establish a connection scene. For the multicast case, the multiple receiving ends support two mechanisms when performing HARQ feedback:

multicast mechanism one (option1 NACK-only feedback, or connectionless-less): if the data is received but can not be solved, NACK is fed back, and the data is not fed back in other cases.

Multicast mechanism two (option2 ACK/NACK feedback, or connectivity-based): if the data is received but cannot be resolved or if the SCI is received but no data is received, a NACK is fed back and if the data is received and correctly resolved, an ACK is fed back.

The invention provides a transmission configuration method and a terminal, aiming at the problems of packet loss, low reliability and low resource utilization rate caused by the fact that a terminal cannot receive a resource corresponding to a resource scheduled by DCI or indicated by SCI in the same period when the PSFCH is out of the activation time.

As shown in fig. 6, an embodiment of the present invention provides a transmission configuration method, applied to a first terminal, including:

601, acquiring transmission configuration;

it should be noted that the transmission configuration is used for configuring a target parameter, and specifically, the target parameter includes: a first predetermined time domain range or a first predetermined timer

Step 602, according to the transmission configuration, executing a transmission control behavior of a target object in a time domain range corresponding to the target parameter;

it should be noted that, one possible interpretation of the time domain range mentioned in the embodiments of the present invention is a time window, and one possible interpretation is a time domain resource set (resource set), where the time domain resource set includes at least one time domain resource, and if there are multiple time domain resources in the set, these resources may be continuous or discrete in time domain, for example, the time domain range includes at least one sidelink slot.

The target object includes: at least one of a first response, a feedback resource (e.g., a Physical Sidelink Feedback Channel (PSFCH)), a Reference Signal (RS), and a measurement report;

specifically, the first response may comprise: a response to at least one of a synchronization request, a connection establishment request, a connection restoration request, a link reestablishment request, a reconfiguration request, a retransmission request, etc., for example, at least one of an allowance or successful synchronization, an allowance or successful establishment of a connection, an allowance or successful restoration of a link, an allowance or successful reestablishment of a link, a reconfiguration, a retransmission, etc.; allowing or successfully synchronizing may include: permission or success as a synchronization reference (synchronization reference), permission or success in transmitting synchronization signals, and the like.

The reference signal may include: at least one of CSI-RS, PT-RS, uplink sounding signal (SRS), Positioning Reference Signal (PRS), etc.;

the measurement report may be, for example: at least one of a channel state information report (CSI report), a reference signal received power report (RSRP report), a reference signal received quality report (RSRQ report), a received signal strength indication report (RSSI report), a PT-RS measurement report, and the like.

It should be noted that, in a specific implementation, the time domain ranges or timers with different lengths may be designed for different target objects, or the time domain ranges or timers with the same length may be designed for different target objects.

It should be further noted that, in the embodiments of the present invention, the transmission configuration may limit receiving and/or transmitting, and when the transmission configuration at least limits receiving of the terminal, it may be regarded as a side link Discontinuous Reception (DRX) configuration.

Specifically, the acquisition mode of the transmission configuration includes at least one of the following:

a11, configuring network side equipment;

a12, pre-configuration;

a13, agreement;

a14, other terminal indication;

a15, determined by the first terminal;

for example, the first terminal calculates the time domain range or the duration of the timer according to the resource pool configuration and the indication information in the sidelink downlink control information (SL DCI, i.e. DCI for scheduling, activating or deactivating SL transmission resources).

It should be noted that, the specific operation executed by the first terminal may be different due to different target parameters, and specific implementation manners of different target parameters are described below.

Firstly, when the target parameter is a first preset time domain range

Specifically, in this case, the first preset time domain range includes: a first time domain range and/or a second time domain range; further, the specific implementation manner of step 602 includes at least one of the following:

a211, in the first time domain range, the first terminal does not monitor or receive the target object;

for example, the first terminal does not monitor (or receive) the PSFCH within the first time domain; the first terminal does not monitor (or receive) the CSI-RS within the first time domain range; the first terminal does not monitor (or receive) CSI reports in the first time domain.

It should be noted that the first time domain ranges corresponding to different target objects may be the same or different.

A212, in the second time domain range, the first terminal monitors or receives the target object;

for example, the first terminal monitors (or receives) the PSFCH in a second time domain; the first terminal monitors (or receives) the CSI-RS in a second time domain range; the first terminal monitors (or receives) CSI reports in a second time domain range.

It should be noted that the second time domain ranges corresponding to different target objects may be the same or different.

Further, the specific implementation manner of step 602 includes at least one of the following:

a213, during the running period of the first timer, the first terminal does not monitor or receive the target object;

for example, the first terminal does not monitor (or receive) the PSFCH during the first timer run; the first terminal does not monitor (or receive) the RS during the first timer running; the first terminal does not monitor (or receive) the measurement report during the first timer run.

It should be noted that the first timers corresponding to different target objects may be the same or different.

It should be noted that the round trip time timers corresponding to different target objects may be the same or different.

A214, during the running period of the second timer, the first terminal monitors or receives the target object.

For example, the first terminal monitors (or receives) the PSFCH during the second timer running; the first terminal monitors (or receives) the CSI-RS during the operation of the second timer; the first terminal monitors (or receives) the CSI report during the second timer run.

It should be noted that the second timers corresponding to different target objects may be the same or different.

Further, for example, the first terminal monitors (or receives) the PSFCH during the retransmission timer running; the first terminal monitors (or receives) the RS during the operation of the retransmission timer; the first terminal monitors (or receives) the measurement report during the retransmission timer running.

It should be noted that the retransmission timers corresponding to different target objects may be the same or different.

It should be further noted that, for a target parameter being a first preset time domain range or a first preset timer, the length of each time domain range is greater than or equal to at least one of the following parameters:

a31, a time interval between the SL DCI and the first preset feedback resource;

specifically, the first preset feedback resource is a feedback resource corresponding to an xth SL transmission resource in SL DCI scheduling or activated SL transmission resources, where X is a positive integer, and in this case, the first preset feedback resource is a feedback resource corresponding to any one of the SL transmission resources in SL DCI scheduling or activated SL transmission resources; for example, the first preset feedback resource is a PSFCH corresponding to a first SL transmission resource scheduled by the SL DCI, and correspondingly, the length of the time domain range is greater than or equal to a time interval from the SL DCI to the PSFCH corresponding to the first SL transmission resource scheduled by the SL DCI; for example, the first preset feedback resource is a PSFCH corresponding to a last SL transmission resource scheduled by the SL DCI, and correspondingly, the length of the time domain range is greater than or equal to a time interval from the SL DCI to the PSFCH corresponding to the last SL transmission resource scheduled by the SL DCI.

Preferably, the length of the timing duration of the first timer or the first time domain range satisfies this condition.

A32, time interval between the first preset transmission resource and the second preset feedback resource;

specifically, the first preset transmission resource includes one of:

a41, the a-th transmission resource among the transmission resources included in the sidelink semi-persistent scheduling (SL SPS);

specifically, a is a positive integer, that is, a refers to any one transmission resource. Further, in this case, at least one of the a-th Sidelink Control Information (SCI), the a-th Physical Sidelink Control Channel (PSCCH), and the a-th physical sidelink shared channel (PSCCH) among transmission resources included in the SL SPS is referred to; preferably, the a-th transmission resource refers to an a-th psch among transmission resources included in the SL SPS.

A42, B transmission resource in the transmission resources contained in the side link configuration authorization (SL CG);

Further, in this case, at least one of the bsh SCI, the bsch, and the bssch in the transmission resources included in the SL CG is referred to; preferably, the B-th transmission resource refers to a B-th psch among transmission resources included in the SL CG.

A43, C transmission resource in the transmission resource scheduled by SL DCI;

specifically, C is a positive integer, that is, C refers to any one transmission resource. Further, in this case, at least one of the C-th SCI, the C-th PSCCH, and the C-th PSCCH in the transmission resources scheduled by the SL DCI is referred to; preferably, the C-th transmission resource refers to a C-th psch among transmission resources scheduled by the SL DCI.

A44, D transmission resource in the transmission resources indicated by SCI;

specifically, D is a positive integer, that is, D refers to any one transmission resource. Further, in this case, at least one of a D-th SCI, a D-th PSCCH, and a D-th PSCCH in the transmission resources indicated by the SCI is referred to; preferably, the D-th transmission resource refers to a D-th psch among transmission resources indicated by the SCI.

A45, E transmission resource in the transmission resources reserved by SCI;

specifically, E is a positive integer, that is, E refers to any one transmission resource. Further, in this case, at least one of an E-th SCI, an E-th PSCCH, and an E-th PSCCH in the transmission resources reserved by the SCIs is referred to; preferably, the E-th transmission resource refers to an E-th psch among transmission resources reserved for SCI.

A46, F transmission resource in the transmission resources corresponding to one Transmission Block (TB);

specifically, F is a positive integer, that is, F refers to any one transmission resource.

Specifically, it should be noted that the time interval between the first preset transmission resource and the second preset feedback resource includes one of:

a321, time interval from the H transmission resource to the J transmission resource;

it should be noted that H, J are all positive integers, that is, H, J all refer to any transmission resource. For example, if the feedback resource corresponding to the jth transmission resource is a PSFCH corresponding to the first SL transmission resource scheduled by the SL DCI, the time interval may be a time interval between the first transmission resource scheduled by the SL DCI and the PSFCH corresponding to the first SL transmission resource scheduled by the SL DCI; for example, if the feedback resource corresponding to the jth transmission resource is a PSFCH corresponding to the last SL transmission resource scheduled by the SL DCI, the time interval may be a time interval between the first transmission resource scheduled by the SL DCI and the PSFCH corresponding to the last SL transmission resource scheduled by the SL DCI.

A322, time interval from the Kth transmission resource to the feedback resource corresponding to the Kth transmission resource;

it should be noted that K is a positive integer, that is, K refers to any one transmission resource. For example, the time interval is a time interval between a first transmission resource in the SL transmission resources scheduled by the SCI and a PSFCH corresponding to the first transmission resource; for example, the time interval is the time interval between the last transmission resource in the SL transmission resources scheduled by the SCI and the PSFCH corresponding to the last transmission resource.

It should be further noted that, in the case that the target parameter is the first preset time domain range or the target parameter is the first preset timer, the transmission configuration method according to the embodiment of the present invention further includes:

acquiring a first target time, where the first target time is a first preset time, or the first target time is a time when the first preset time deviates by a first deviation amount (that is, the first target time is the first preset time + the first deviation amount);

wherein the first target time is a starting point of the time domain range.

The first offset may be obtained by any one of the methods a11 to a 15.

Specifically, the first preset time is related to at least one of the following cases (it should be noted that each of the following cases specifically refers to a specific time point, that is, the first preset time is determined by the following case:

a501, resource occupation is performed;

specifically, the first preset time is when the resource is preempted, or the first preset time is after the resource is preempted.

It should be noted that the preempted resource here means that a resource indicated by or reserved by other terminals is preempted, or the preempted resource means that a desired transmission resource is preempted.

A502, receiving SL DCI;

specifically, the first preset time is when the SL DCI is received, or the first preset time is after the SL DCI is received.

Optionally, at this time, the time domain range is greater than or equal to a time interval between the SL DCI and the first preset feedback resource.

A503, performing second preset transmission;

specifically, the first preset time is when second preset transmission is performed, or the first preset time is after second preset transmission is performed.

Optionally, at this time, the time domain range is greater than or equal to a time interval between the first preset transmission resource and the second preset feedback resource.

It should be noted that, for the above cases a502 and a503, since there is no feedback of the TB corresponding to a certain transmission or no feedback of the transmission in a time before the PSFCH time corresponding to the transmission, the first terminal (which may also be regarded as a psch/PSCCH TX UE) may not monitor the PSFCH, thereby saving energy.

Specifically, the second predetermined transmission resource is the transmission resource indicated in the above-mentioned a41-a 46.

A504, SCI transmission;

specifically, the first preset time is when the SCI is sent, or the first preset time is after the SCI is sent.

A505, transmitting PSCCH;

specifically, the first preset time is when the PSCCH is transmitted, or the first preset time is after the PSCCH is transmitted.

A506, the situation of transmitting PSSCH;

specifically, the first preset time is when the psch is transmitted, or the first preset time is after the psch is transmitted.

A507, the situation of sending a first request;

specifically, the first preset time is when the first request is sent, or the first preset time is after the first request is sent.

It should be noted that the first request may include: a synchronization request, a reference signal request, a measurement report request (e.g., at least one of a CSI report request, an RSRP report request, an RSRQ report request, an RSSI report request), a connection establishment request, a connection recovery request, a link reestablishment request, a reconfiguration request, a retransmission request, and the like.

A508, receiving the target object;

specifically, the first preset time is when the target object is received, or the first preset time is after the target object is received.

A509, receiving the confirmation response;

specifically, the first preset time is when an acknowledgement is received, or the first preset time is after the acknowledgement is received.

It should be noted that, here, the case where ACK is received is referred to.

Specifically, such cases include: for multicast mechanism two (multicast option2) or unicast, at least one acknowledgement is received. For example, the first terminal receives at least one ACK for each associated terminal of a certain sidelink grant (sidelink grant) or a certain TB, where it should be noted that receiving at least one ACK may refer to receiving ACKs of the associated terminals at different time points, respectively.

Wherein, the sidelink grant can be understood as at least one of the transmission resources indicated or reserved by the SL DCI, the SL SPS, the SL CG and the SCI.

For example, the SCI indicates three transmission resources, which are denoted as transmission resource 1, transmission resource 2 and transmission resource 3, the first terminal (which may be regarded as psch/PSCCH TX UE) receives ACKs from all the second terminals (which may be regarded as psch/PSCCH RX UE) on the PSFCH corresponding to transmission resource 2, the psch/PSCCH TX UE may not monitor the PSFCH corresponding to transmission resource 3, and/or the first terminal starts the first timer at this time. It should be noted that, at this time, the psch/PSCCH TX UE considers that the TB corresponding to the transmission resource is successfully transmitted, so the PSCCH and PSCCH TX UE may not monitor the PSFCH.

A510, the situation that the target object is not monitored or received;

specifically, the first preset time is when the target object is not monitored (or not received), or the first preset time is after the target object is not monitored (or not received).

Specifically, in this case, one of the following items is specifically included:

a5101, for a first multicast mechanism (multicast option1), the first terminal does not monitor or receive the target object of the associated terminal on the feedback resources corresponding to all the transmission resources;

for example, for the first multicast mechanism, the first terminal does not monitor (or does not receive) the PSFCH of the associated terminal on the PSFCH corresponding to all transmission resources.

For example, for the first multicast mechanism, the PSFCHs of all pschs/PSCCH RX UEs at the time of the PSFCH corresponding to a certain sidelink grant or a first transmission resource to a last transmission resource of a certain TB are not detected.

For example, for multicast option1, the SCI indicates three transmission resources, the psch/PSCCH TX UE does not detect the PSFCH of any psch/PSCCH RX UE on the PSFCH corresponding to 3 transmission resources, and the psch/PSCCH TX UE may start a first preset timer. It should be noted here that, at this time, the psch/PSCCH TX UE considers the TB corresponding to the transmission resource to be successful, so the psch/PSCCH TX UE may no longer monitor the PSFCH.

A5102, for the first multicast mechanism, the first terminal does not monitor or receive the condition of the target object of the associated terminal on the feedback resource corresponding to the lth transmission resource;

specifically, L is a positive integer, and L denotes any transmission resource. For example, for the first multicast mechanism, the first terminal does not monitor (or receive) the target object of the associated terminal on the PSFCH corresponding to the first transmission resource.

For example, for the first multicast mechanism, the PSFCH of all pschs/PSCCH RX UEs at the time of the PSFCH corresponding to any transmission resource of a certain sidelink grant or a certain TB is not detected.

A5103, for the first multicast mechanism, the first terminal does not monitor or receive the condition of the target object of the associated terminal on the feedback resource corresponding to the last transmission resource;

for example, for the first multicast mechanism, the first terminal does not monitor (or receive) the target object of the associated terminal on the PSFCH corresponding to the last transmission resource.

For example, for the first multicast mechanism, the PSFCH of all pschs/PSCCH RX UEs at the time of the PSFCH corresponding to the last transmission resource of a certain sidelink grant or a certain TB is not detected.

For example, for multicast option1, the SCI indicates three transmission resources, the psch/PSCCH TX UE does not detect the PSFCH of any psch/PSCCH RX UE on the PSFCH corresponding to the 3 rd transmission resource, and the psch/PSCCH TX UE may start a first preset timer. It should be noted here that, at this time, the psch/PSCCH TX UE considers the TB corresponding to the transmission resource to be successful, so the psch/PSCCH TX UE may no longer monitor the PSFCH.

A511, the condition that the non-acknowledgement response is not monitored or received;

specifically, the first preset time is when no non-acknowledgement response is monitored (or not received), or the first preset time is after no non-acknowledgement response is monitored (or not received).

It should be noted that this refers to the case where no NACK is received or monitored.

a5111, for the first multicast mechanism, the first terminal does not monitor or receive the non-acknowledgement response of the associated terminal on the feedback resources corresponding to all the transmission resources;

for example, for the first multicast mechanism, the first terminal does not monitor (or receive) NACK of associated terminals on the PSFCH corresponding to all transmission resources.

For example, for the first multicast mechanism, NACK for all psch/PSCCH RX UEs at the time of the PSFCH corresponding to a certain sidelink grant or a certain TB from the first transmission resource to the last transmission resource is not detected.

A5112, for the first multicast mechanism, the first terminal does not monitor or receive the non-acknowledgement response of the associated terminal on the feedback resource corresponding to the mth transmission resource;

specifically, M is a positive integer, and M denotes any transmission resource. For example, for the first multicast mechanism, the first terminal does not monitor (or receive) the NACK of the associated terminal on the PSFCH corresponding to the first transmission resource.

For example, for the first multicast mechanism, NACK of all pschs/PSCCH RX UEs at the time of the PSFCH corresponding to any transmission resource of a certain sidelink grant or a certain TB is not detected.

A5113, for the first multicast mechanism, the first terminal does not monitor or receive the non-acknowledgement response of the associated terminal on the feedback resource corresponding to the last transmission resource;

For example, for the first multicast mechanism, NACK for all pschs/PSCCHs RX UEs at the time of the PSFCH corresponding to the last transmission resource of a certain sidelink grant or a certain TB is not detected.

For example, for multicast option1, where the SCI indicates three transmission resources, the psch/PSCCH TX UE does not detect any NACK for the psch/PSCCH RX UE over 3 transmissions of the corresponding PSFCH, and the psch/PSCCH TX UE may start a first preset timer. It should be noted here that, at this time, the psch/PSCCH TX UE considers the TB corresponding to the transmission resource to be successful, so the psch/PSCCH TX UE may no longer monitor the PSFCH.

A512, the first terminal determines the condition of successful transmission;

specifically, the first preset time is when the first terminal determines that the transmission is successful, or the first preset time is after the first terminal determines that the transmission is successful.

A513, the first terminal cannot transmit the target object;

specifically, the first preset time is when the first terminal cannot transmit the target object, or the first preset time is after the first terminal cannot transmit the target object.

For example, due to half-duplex limitation, or due to simultaneous presence of higher priority transmissions or receptions, e.g., at least one of higher priority Uu transmissions, higher priority other channel transmissions, high priority transmissions of other RATs, the terminal cannot transmit the target object.

Specifically, the fact that the first terminal cannot transmit the target object means that the first terminal cannot receive the PSFCH for a sidelink grant or a TB.

For example, the terminal may not be able to receive the PSFCH due to half-duplex limitations, or due to simultaneous higher priority transmissions or receptions, e.g., at least one of a higher priority Uu transmission, a higher priority other channel transmission, a high priority transmission of other RATs.

A514, the first terminal can not transmit SCI;

specifically, the first predetermined time is when the first terminal cannot transmit the SCI, or the first predetermined time is after the first terminal cannot transmit the SCI.

A515, the first terminal can not transmit PSSCH;

specifically, the first preset time is when the first terminal cannot transmit the PSSCH, or the first preset time is after the first terminal cannot transmit the PSSCH.

A516, the first terminal cannot transmit the PSCCH;

specifically, the first preset time is when the first terminal cannot transmit the PSCCH, or the first preset time is after the first terminal cannot transmit the PSCCH.

It should be noted that, when the first preset time is a508, a510, or a511, the first terminal further performs at least one of the following operations:

a61, the first terminal determines that the transmission is successful;

a62, the first terminal does not monitor feedback resources any more;

specifically, the first terminal no longer listens to the PSFCH.

It should be further noted that, when the target parameter is a first preset timer, after the obtaining of the first preset time, the method further includes:

and starting the first preset timer at the first target moment.

It should be further noted that, when the target parameter is a first preset time domain range, the method includes: in a first time domain range or a second time domain range, a first target time of the first time domain range is different from a first target time of the second time domain range.

It should be noted that the implementation procedure corresponding to the embodiment of the present invention may include:

1. UE1 requests UE2 to send CSI-RS, UE2 to send CSI-RS, UE1 to monitor CSI-RS (like PSCCH/PSSCH TX UE sends SCI, PSCCH/PSSCH RX UE feeds back PSFCH, PSCCH/PSSCH TX monitors PSFCH);

2. the UE2 sends CSI-RS and/or the UE2 requests UE1 CSI report, UE1 feeds back CSI report, UE2 monitors CSI-RS report (similar to PSCCH/PSCCH TX UE sending SCI, PSCCH/PSCCH RX UE feeding back PSFCH, PSCCH/PSCCH TX monitoring PSFCH).

Here UE1 and PSCCH/PSCCH TX UE refer to the first terminal described above.

It should be noted here that a sending user of a TB needs to detect a feedback corresponding to the TB, that is, a PSCCH/PSCCH associated PSFCH where the TB is located, and a receiving user of the TB needs to send a feedback corresponding to the TB on the associated PSFCH. A user may be a transmitting user or a receiving user, respectively, at different times. That is, the psch/PSCCH TX UE mentioned above indicates a user transmitting psch/PSCCH, a PSCCH TX UE indicates a user transmitting PSCCH, a psch/PSCCH TX UE indicates a user receiving psch/PSCCH, and a PSCCH TX UE indicates a user receiving PSCCH.

It should be noted that, the associated terminal mentioned in the embodiment of the present invention refers to a terminal that expects to receive the resource sent by the first terminal, or a terminal that the first terminal expects to be able to receive the target object, for example, when the first terminal sends a certain multicast packet, the associated terminal may be all other member terminals in the group, and the first terminal expects to receive the target object sent by the member terminals.

It should be further noted that the transmission configuration in the embodiment of the present invention may have a corresponding relationship with the resource pool, for example, the resource pool 1 corresponds to the transmission configuration 1, and the resource pool 2 corresponds to the transmission configuration 2.
