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 discontinuous reception (Discontinuous Reception, DRX) of an interface (e.g. Uu port) between a terminal and a network side device, a user only listens to a physical downlink control channel (Physical Downlink Control Channel, PDCCH) during an activation time, so as to achieve the purpose of energy saving, where the activation time includes a duration (on duration), an activity timer (activity timer) running and a retransmission timer (retransmission timer) running. Uu DRX does not limit the time of uplink and other downlink transmissions of the user, e.g. the user may send a hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat Request Acknowledge, HARQ-ACK) to the base station outside the activation time.

A sidelink (sidelink, direct communication link, etc., abbreviated as SL) may include one or more SL resources during a Semi-persistent scheduling (Semi-Persistent Scheduling, SPS) period, a SL Configuration Grant (CG) period may include one or more SL resources, a SL downlink control information (Downlink control information, DCI) (DCI for scheduling SL transmission resources) may schedule one or more SL resources, and a sidelink control information (Sidelink Control Information, SCI) may schedule one or more SL resources that may be reserved for subsequent transmission for a period of time. Each resource may include SCI, and only part of the resources may be within the activation time and the other part of the resources may be outside the activation time in the same period or in a DCI scheduled or indicated resource. It may also occur that the physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH) corresponding to a resource scheduled by one DCI or indicated by one SCI is outside the activation time within the same period.

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

Disclosure of Invention

The embodiment of the invention provides a transmission configuration method and a terminal, which are used for solving the problems of packet loss, low reliability and low resource utilization rate caused by the fact that the terminal will not receive one DCI or PSFCH when the PSFCH corresponding to one DCI scheduled or one SCI indicated resource is out of the activation time in the same period.

In order to solve the technical problems, the embodiment of the invention adopts the following scheme:

Detailed Description

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

In describing embodiments of the present invention, some concepts used in the following description are first explained.

1. Discontinuous reception (Discontinuous Reception, DRX) introduction of interface (i.e. Uu port) between long term evolution (Long Term Evolution, LTE) and New radio, NR, terminals and network side devices

Both LTE and NR introduce DRX mechanisms 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) period is the interval of DRX on, and the UE enters an off period of one DRX cycle (DRX cycle) if it is not scheduled after the on duration period.

2. Side link (abbreviated SL) introduction to sidelink, direct communication link, etc

The sidelink design supports two resource allocation modes, a scheduled resource allocation (Scheduled resource allocation) mode (commonly referred to as mode-1) and an autonomous resource selection (autonomous resource selection) mode (commonly referred to as mode-2), respectively. The former is controlled by the network side equipment and allocates resources for each UE, and the latter is autonomously selected by the UE. In mode-1, the radio resource control (Radio Resource Control, RRC) or one downlink control information (Downlink control information, DCI) may indicate one or more resources, e.g., as shown in fig. 2, such as resource SL Configured grant (SL CG) where a configuration period occurs; in mode-2 the user gets the resources through sensing or detection, one SCI may indicate one or more resources, and further they may be reserved periodically, e.g. as shown in fig. 3. In particular, the terminal determines which resources have been occupied by other terminals by detecting SCI and/or measurement, thereby selecting resources for own transmission from the remaining resources.

The PSCCH in LTE Sidelink carries SCI, and the PSCCH and PSSCH in NR Sidelink respectively carry a part of SCI. SCI is used to schedule PSSCH. The SCI may indicate transmission resources and further may reserve these resources for future transmissions. The physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH) is used for feeding back the sidelink HARQ-ACK information, and after the user determines the sidelink HARQ-ACK information, the user can further send the sidelink HARQ-ACK information to the base station through the PUCCH or the PUSCH.

PSFCH resource

One PSSCH frequency domain occupies N sub-channels, and one PSFCH resource frequency domain occupies only 1 RB, so that the number of PSFCH RBs in the same resource pool is far greater than that of PSSCH occasin.

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

PSFCH occasin occurs once every N slot (sidelink slot), i.e., the period n=1, 2,4 of the PSFCH. Thus, some SL slots have PSCCH/PSSCH and PSFCH, and some have no PSFCH only PSCCH/PSSCH. There are N possible PSSCH occlusions associated with the PSFCH occlusions per period, and the time of PSSCH occlusions associated with the PSSCH occlusions on slot m is no earlier than m+k, where k=2, 3.

Note that: the subcarrier spacings (SubCarrier Spacing, SCS) of the above parameters may be the same or different, and K and N are logical slots (SL slots), so that the actual distance between K SL slots may be greater than the duration corresponding to K physical slots, and the actual distance between N SL slots may be greater than the duration corresponding to N physical slots. As shown in fig. 5, it is assumed that

physical slots

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

logical slots

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

Cast type and HARQ feedback mode

Three transmission modes of broadcasting, multicasting and unicasting are supported in NR sidelink. The multicast of NR sidelink supports two use cases of connection-based multicast and connectionless multicast, wherein the connection-based multicast refers to the situation that connection is established between multicast UE, and the connectionless mode refers to the situation that the multicast UE does not know other UEs in the group and does not establish connection. For the multicast case, multiple receivers support two mechanisms when performing HARQ feedback:

multicast mechanism one (option 1 NACK-only feedback, or connectionless mechanism control-less): if the data is received but cannot be decoded, NACK is fed back, otherwise no feedback is given.

Multicast mechanism two (option 2 ACK/NACK feedback, or connection-based): if the data is received but not resolved or the SCI is received but not received, a NACK is fed back and if the data is received and resolved correctly, 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 that a terminal will not receive SCI or PSFCH when PSFCH corresponding to a DCI scheduled or indicated resource in the same period is out of activation time.

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

step 601, acquiring a transmission configuration;

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

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

it should be noted that, in the embodiment of the present invention, one possible explanation of the time domain range is a time window, and one possible explanation 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 the 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 include: a response to at least one of a synchronization request, a connection establishment request, a connection recovery request, a link reestablishment request, a reconfiguration request, a retransmission request, etc., e.g., allowing or successfully synchronizing, allowing or successfully establishing a connection, allowing or successfully recovering a link, allowing or successfully reestablishing a link, reconfiguration, retransmission, etc.; allowing or successful synchronization may include: at least one of a synchronization signal, etc., is allowed or successfully transmitted as a synchronization reference (synchronization reference).

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

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

It should be noted that, in the embodiment of the present invention, when in specific implementation, time domain ranges or timers with different lengths may be designed for different target objects, or 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 reception and/or transmission, and may be considered as a side link Discontinuous Reception (DRX) configuration when the transmission configuration at least limits terminal reception.

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

a11, configuring network side equipment;

a12, pre-configuring;

a13, protocol convention;

a14, other terminal instructions;

a15, determining by the first terminal;

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

It should be noted that, because the target parameters are different, the specific execution operation of the first terminal may also be different, and the specific implementation manner of the different target parameters will be described below.

1. When the target parameter is the 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:

Specifically, in this case, the first preset timer includes: a first timer and/or a second timer; the first Timer may be at least one of a round trip time (RTT Timer), a waiting Timer, a non-working Timer (off Timer), a sleep Timer (sleep Timer), etc., and the second Timer may be at least one of a retransmission Timer (ReTX Timer), an activity Timer (activity Timer), a working Timer (on duration Timer), a measurement Timer (measurement Timer), a report Timer (report Timer), a response Timer (response Timer), etc.

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

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

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

Further, for example, the first terminal does not monitor (or not receive) the PSFCH during the round trip delay timer running; the first terminal does not monitor (or not receive) the CSI-RS during the round trip delay timer running; the first terminal does not monitor (or not receive) CSI reports during the round trip delay timer running.

Note that the round trip delay timers corresponding to different target objects may be the same or different.

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 second timer running; the first terminal monitors (or receives) CSI reports during the second timer running.

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 operation of the retransmission timer; 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 operation of the retransmission timer.

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 the target parameter being the first preset time domain range or the first preset timer, the length of the time domain range satisfies at least one of the following parameters or more:

time interval between A31, 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 the SL DCI scheduled 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 scheduled or activated by the SL DCI; for example, the first preset feedback resource is a PSFCH corresponding to a first SL transmission resource scheduled by the SL DCI, and the length of the corresponding time domain range is greater than or equal to a time interval between the SL DCI and 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 of the SL DCI schedule, and the length of the corresponding time domain range is greater than or equal to a time interval between the SL DCI and the PSFCH corresponding to the last SL transmission resource of the SL DCI schedule.

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

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

specifically, the first preset transmission resource includes one of the following:

a41, an a-th transmission resource among transmission resources contained in a side link 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 an a-th side link control information (SCI), an a-th physical side link control channel (PSCCH), and an a-th physical side link shared channel (PSSCH) among transmission resources included in the SL SPS; preferably, the a-th transmission resource refers to an a-th PSSCH among transmission resources included in the SL SPS.

A42, B-th transmission resource among transmission resources included in a side link configuration grant (SL CG);

specifically, B is a positive integer, that is, B refers to any one transmission resource. Further, in this case, at least one of a B-th SCI, a B-th PSCCH, and a B-th PSCCH in transmission resources included in the SL CG is referred to; preferably, the B-th transmission resource refers to a B-th PSSCH among transmission resources included in the SL CG.

Further, in this case, at least one of the D SCI, the D PSCCH, and the D PSSCH in the transmission resource indicated by the SCI is referred to; preferably, the D-th transmission resource refers to a D-th PSSCH in the transmission resource indicated by the SCI.

A45, E-th transmission resource in 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 pscsch among transmission resources reserved for SCIs; preferably, the E-th transmission resource refers to the E-th PSSCH in the transmission resource reserved by the SCI.

A46, the F-th 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 the following:

a321, a time interval between feedback resources corresponding to the H transmission resource and the J transmission resource;

note that H, J is a positive integer, that is, H, J refers to any one transmission resource. For example, if the feedback resource corresponding to the J-th transmission resource is the 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 J-th transmission resource is the PSFCH corresponding to the last SL transmission resource of the SL DCI schedule, the time interval may be the time interval between the first transmission resource of the SL DCI schedule and the PSFCH corresponding to the last SL transmission resource of the SL DCI schedule.

A322, the time interval between the transmission resource 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 the PSFCH corresponding to the first transmission resource; for example, the time interval is a 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, whether the target parameter is the first preset time domain range or the target parameter is the first preset timer, the transmission configuration method in the embodiment of the present invention further includes:

acquiring a first target time, wherein the first target time is a first preset time or the first target time is a time when the first preset time deviates from the first preset time by a first deviation amount (namely, the first target time=the first preset time+the first deviation amount);

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

The first offset may be obtained by any of the methods a11 to a15 described above.

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

a501, the situation of preempted resources;

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

It should be noted that, the preempted resource herein refers to a resource indicated by or reserved by another terminal being preempted, or a preempted resource refers to a desired transmission resource being preempted.

A502, receiving SL DCI;

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

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

A503, carrying out second preset transmission;

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

Optionally, 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 feedback of the transmission in a time before the PSFCH time corresponding to the certain transmission, the first terminal (may also be regarded as PSSCH/PSCCH TX UE) may not monitor the PSFCH, thereby saving energy.

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

A504, sending SCI;

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

A505, transmitting PSCCH;

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

A506, sending PSSCH;

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

A507, sending a first request;

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

It should be noted that the first request may include: at least one of a synchronization request, a reference signal request, a measurement report request (e.g., at least one of CSI report request, RSRP report request, RSRQ report request, 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 condition of the target object;

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

A509, receiving a confirmation response;

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

Here, the term "ACK" refers to a case where an ACK is received.

Specifically, this case includes: for multicast mechanism two (multicast option 2) 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 the ACKs of the associated terminals at different time points, respectively.

The sidelink grant may be understood as a transmission resource indicated or reserved by at least one of SL DCI, SL SPS, SL CG and SCI.

For example, SCI indicates three transmission resources, denoted as transmission resource 1, transmission resource 2 and transmission resource 3, and the first terminal (which may be regarded as PSSCH/PSCCH TX UE) receives ACKs of all second terminals (which may be regarded as PSSCH/PSCCH RX UE) on the PSFCH corresponding to transmission resource 2, and the PSSCH/PSCCH TX UE may not monitor the PSFCH corresponding to transmission resource 3 anymore and/or the first terminal starts the first timer. At this time, the PSSCH/PSCCH TX UE considers that the TB transmission corresponding to the transmission resource is successful, so PSFCH may not be monitored any more.

A510, the condition 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 after the target object is not monitored (or not received).

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

a5101, for a first multicast mechanism (multicast option 1), the first terminal does not monitor or receive the situation of the target object of the associated terminal on the feedback resources corresponding to all the transmission resources;

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

For example, for multicast mechanism one, no PSFCH of all PSSCH/PSCCH RX UEs is detected at the PSFCH time corresponding to the first to last transmission resource for a certain sidelink grant or a certain TB.

For example, for multicast 1, SCI indicates three transmission resources, PSSCH/PSCCH TX UE does not detect any PSFCH of PSSCH/PSCCH RX UE on PSFCH corresponding to 3 transmission resources, and PSSCH/PSCCH TX UE may start the first preset timer. Here, the PSSCH/PSCCH TX UE considers that the TB corresponding to the transmission resource is successful, so the PSSCH/PSCCH TX UE may not monitor the PSFCH.

A5102, for the multicast mechanism I, the first terminal does not monitor or receive the situation of the target object of the associated terminal on the feedback resource corresponding to the L-th transmission resource;

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

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

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

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

For example, for multicast mechanism one, no PSFCH for all PSSCH/PSCCH RX UEs at the PSFCH time corresponding to the last transmission resource for a certain sidelink grant or a certain TB is detected.

For example, for multicast 1, SCI indicates three transmission resources, PSSCH/PSCCH TX UE does not detect any PSFCH of PSSCH/PSCCH RX UE on PSFCH corresponding to 3 rd transmission resources, and PSSCH/PSCCH TX UE may start the first preset timer. Here, the PSSCH/PSCCH TX UE considers that the TB corresponding to the transmission resource is successful, so the PSSCH/PSCCH TX UE may not monitor the PSFCH.

A511, a condition in which no non-acknowledgement is monitored or received;

specifically, the first preset time is when the non-acknowledgement is not monitored (or not received), or after the non-acknowledgement is not monitored (or not received).

Note that this refers to a case where NACK is not received or not monitored.

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

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

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

For example, for multicast mechanism one, no NACK is detected for all PSSCH/PSCCH RX UEs at the PSFCH time corresponding to a certain sidelink grant or a certain TB from the first transmission resource to the last transmission resource.

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

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

For example, for multicast mechanism one, no NACK for all PSSCH/PSCCH RX UEs at the PSFCH time corresponding to any transmission resource for a certain sidelink grant or a certain TB is detected.

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

For example, for multicast mechanism one, no NACK for all PSSCH/PSCCH RX UEs at the PSFCH time corresponding to the last transmission resource for a certain sidelink grant or a certain TB is detected.

For example, for multicast option1, SCI indicates three transmission resources, no NACK for any PSSCH/PSCCH RX UE is detected by the PSSCH/PSCCH TX UE on the PSFCH corresponding to the 3 transmissions, and the PSSCH/PSCCH TX UE may start the first preset timer. Here, the PSSCH/PSCCH TX UE considers that the TB corresponding to the transmission resource is successful, so the PSSCH/PSCCH TX UE may not monitor the PSFCH.

A512, the first terminal determines the successful transmission condition;

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

A513, wherein the first terminal cannot transmit the target object;

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

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

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

A514, the situation that the first terminal cannot transmit SCI;

Here UE1 and PSCCH/pscsch TX UE are referred to as the first terminal described above.

It should be noted here that a transmitting user of a TB needs to detect feedback corresponding to the TB, i.e. the PSFCH associated with the PSCCH/PSSCH where the TB is located, and a receiving user of a TB needs to send feedback corresponding to the TB on the associated PSFCH. One user may be a transmitting user or a receiving user, respectively, at different times. That is, the above-mentioned PSSCH/PSCCH TX UE means a user transmitting PSSCH/PSCCH, PSFCH TX UE means a user transmitting PSFCH, PSSCH/PSCCH TX UE means a user receiving PSSCH/PSCCH, and PSFCH TX UE means a user receiving PSFCH.
