由用户设备执行的方法以及用户设备Method performed by user equipment and user equipment 技术领域technical field
本发明涉及一种由用户设备执行的方法以及用户设备。The present invention relates to a method performed by a user equipment and the user equipment.
背景技术Background technique
在5G V2X(见非专利文献4)中，网络侧(例如基站等)可以通过为UE配置和/或激活“SL配置许可”，或者通过DCI为UE分配一个或多个PSSCH传输资源。另外，网络侧(例如基站等)可以为UE提供上行资源(例如PUCCH资源，又如PUSCH资源)，用于报告与所述PSSCH传输有关的HARQ-ACK信息。在HARQ-ACK信息上报的机制中，需要解决的问题包括在所有情况下都需要保证上报的每一个HARQ-ACK信息比特都正确地设置一个HARQ-ACK值和/或优先级值。In 5G V2X (see Non-Patent Document 4), the network side (eg, base station, etc.) can allocate one or more PSSCH transmission resources to the UE by configuring and/or activating the "SL configuration license" for the UE, or through DCI. In addition, the network side (eg, base station, etc.) may provide the UE with uplink resources (eg, PUCCH resources, or PUSCH resources) for reporting HARQ-ACK information related to the PSSCH transmission. In the HARQ-ACK information reporting mechanism, the problems to be solved include ensuring that each HARQ-ACK information bit reported is correctly set with a HARQ-ACK value and/or a priority value in all cases.

GNSS的例子可以包括GPS(Global Positioning System，全球定位系 统)、GLONASS(GLObal NAvigation Satellite System，全球导航卫星系统)、BeiDou(北斗导航卫星系统)、Galileo(伽利略导航卫星系统)、QZSS(Quasi-Zenith Satellite System，准天顶卫星系统)等。Examples of GNSS may include GPS (Global Positioning System), GLONASS (GLObal NAvigation Satellite System), BeiDou (Beidou Navigation Satellite System), Galileo (Galileo Navigation Satellite System), QZSS (Quasi-Zenith) Satellite System, quasi-zenith satellite system), etc.
SL载波内可以配置一个或多个(例如一个)SL BWP。对每一个SL BWP，可以通过参数startSLsymbols(或者参数sl-StartSymbol)配置可以用于SL传输的起始符号(例如记所述符号在时隙内的编号为
Figure PCTCN2021108596-appb-000010
)，以及通过参数lengthSLsymbols(或者参数sl-LengthSymbols)配置可以用于SL传输的符号个数(例如记所述符号个数为
Figure PCTCN2021108596-appb-000011
)，其中所述

个符号可以是连续的符号。

例如
Figure PCTCN2021108596-appb-000017
所述“可以用于SL传输的符号”可以称为“SL符号”。记SL符号的集合(按时间先后顺序)为
Figure PCTCN2021108596-appb-000018
则
Figure PCTCN2021108596-appb-000019
Figure PCTCN2021108596-appb-000020
例如，若
Figure PCTCN2021108596-appb-000021
则SL符号的集合为{7，8，9，10，11，12，13}。 One or more (eg, one) SL BWPs may be configured within the SL carrier. For each SL BWP, the start symbol that can be used for SL transmission can be configured through the parameter startSLsymbols (or the parameter sl-StartSymbol) (for example, the number of the symbol in the time slot is
Figure PCTCN2021108596-appb-000010
), and configure the number of symbols that can be used for SL transmission through the parameter lengthSLsymbols (or the parameter sl-LengthSymbols) (for example, record the number of symbols as
Figure PCTCN2021108596-appb-000011
), where the
Figure PCTCN2021108596-appb-000012
symbols can be consecutive symbols.
Figure PCTCN2021108596-appb-000013
The set of values can be written as
Figure PCTCN2021108596-appb-000014
For example
Figure PCTCN2021108596-appb-000015
The set of values can be written as
Figure PCTCN2021108596-appb-000016
For example
Figure PCTCN2021108596-appb-000017
The "symbols available for SL transmission" may be referred to as "SL symbols". Denote the set of SL symbols (in chronological order) as

but
Figure PCTCN2021108596-appb-000019
Figure PCTCN2021108596-appb-000020
For example, if

Then the set of SL symbols is {7, 8, 9, 10, 11, 12, 13}.
只有满足一定的条件的时隙才可以用于SL传输。例如，所述时隙中至少符号
Figure PCTCN2021108596-appb-000022
符号
Figure PCTCN2021108596-appb-000023
符号
Figure PCTCN2021108596-appb-000024
是上行符号(例如通过SIBl中的servingCellConfigCommon中的tdd-UL-DL-ConfigurationCommon配置的满足所述条件的时隙)。又如，所述时隙必须在一个已配置的资源池(resource pool)的时隙集合中。 Only time slots that meet certain conditions can be used for SL transmission. For example, at least symbols in the slot
Figure PCTCN2021108596-appb-000022
symbol
Figure PCTCN2021108596-appb-000023
symbol
Figure PCTCN2021108596-appb-000024
is an uplink symbol (for example, a time slot that satisfies the condition configured through tdd-UL-DL-ConfigurationCommon in servingCellConfigCommon in SIB1). As another example, the timeslots must be in a set of timeslots in a configured resource pool.
一个SL BWP内可以配置一个或多个资源池，其中，在每一个资源池内，One or more resource pools can be configured in an SL BWP, and in each resource pool,
●在频域，可以通过参数startRB-Subchannel(或者参数sl-StartRB-Subchannel)配置所述资源池在SL BWP内的起始子 信道的起始资源块的位置。● In the frequency domain, the position of the starting resource block of the starting subchannel of the resource pool in the SL BWP can be configured through the parameter startRB-Subchannel (or the parameter s1-StartRB-Subchannel).
●在频域，每个子信道可以由一个或多个资源块组成，具体的资源块个数(称为子信道的大小，例如记为n subChannelSize)可以通过参数subchannelsize(或者参数sl-SubchannelSize)配置。所述n subChannelSize个资源块在频域上可以是连续的。 ●In the frequency domain, each subchannel can be composed of one or more resource blocks, and the specific number of resource blocks (called the size of the subchannel, for example, denoted as n subChannelSize ) can be configured by the parameter subchannelsize (or parameter sl-SubchannelSize) . The n subChannelSize resource blocks may be contiguous in the frequency domain.
●在频域，可以通过参数numSubchannel(或者参数sl-NumSubchannel)配置所述资源池占用的子信道的个数(记为
Figure PCTCN2021108596-appb-000025
)。所述
Figure PCTCN2021108596-appb-000026
个子信道在频域上可以是连续的。 ● In the frequency domain, the number of subchannels occupied by the resource pool can be configured through the parameter numSubchannel (or the parameter sl-NumSubchannel) (denoted as
Figure PCTCN2021108596-appb-000025
). said
Figure PCTCN2021108596-appb-000026
The subchannels may be contiguous in the frequency domain.
●在频域，可以通过参数sl-RB-Number配置所述资源池占用的PRB的个数(记为
Figure PCTCN2021108596-appb-000027
)。可选地，UE可以假定所述
Figure PCTCN2021108596-appb-000028
个PRB中的最后
Figure PCTCN2021108596-appb-000029
个PRB不会被使用。 ● In the frequency domain, the number of PRBs occupied by the resource pool can be configured through the parameter sl-RB-Number (denoted as
Figure PCTCN2021108596-appb-000027
). Alternatively, the UE may assume that the
Figure PCTCN2021108596-appb-000028
the last of the PRBs
Figure PCTCN2021108596-appb-000029
PRBs will not be used.
●在频域，按频率从小到大的顺序，一个资源池内的各个子信道可以分别编号为
Figure PCTCN2021108596-appb-000030
其中，编号为i的子信道可以称为“子信道i”
Figure PCTCN2021108596-appb-000031
●In the frequency domain, in order of frequency from small to large, each sub-channel in a resource pool can be numbered as
Figure PCTCN2021108596-appb-000030
Among them, the sub-channel numbered i can be called "sub-channel i"
Figure PCTCN2021108596-appb-000031
●在时域，可以通过参数timeresourcepool(或者参数sl-TimeResource)配置一个时隙位图，用于指示在一个候选时隙集合中哪个或哪些时隙属于所述资源池。可以看出，在一个资源池内连续的两个时隙在时间上可以不连续(例如，一个帧内的时隙0和时隙6可以是一个资源池中连续的两个时隙)。为方便起见，一个资源池中的时隙集合可以记为{r 0，r 1，r 2，...}。 ● In the time domain, a time slot bitmap can be configured through the parameter timeresourcepool (or parameter sl-TimeResource) to indicate which time slot or time slots in a candidate time slot set belong to the resource pool. It can be seen that two consecutive time slots in one resource pool may be discontinuous in time (eg, time slot 0 and time slot 6 in one frame may be two consecutive time slots in one resource pool). For convenience, the set of time slots in a resource pool can be denoted as {r 0 , r 1 , r 2 , ...}.
与SL操作有关的资源(例如时域资源，又如频域资源，又如码域资源)的分配方式可以分类如下：The allocation of resources related to SL operations (such as time domain resources, or frequency domain resources, or code domain resources) can be classified as follows:
●模式1(Mode 1)：基站调度用于SL传输的资源。● Mode 1 (Mode 1): The base station schedules resources for SL transmission.
●模式2(Mode 2)：UE确定用于SL传输的资源(即基站不参与用于SL传输的资源的调度)。例如，执行SL传输操作的UE自主确定用于SL传输的资源。● Mode 2 (Mode 2): The UE determines the resources for SL transmission (ie, the base station does not participate in the scheduling of resources for SL transmission). For example, a UE performing an SL transmission operation autonomously determines resources for SL transmission.
UE可以通过SCI(Sidelink Control Information，直行控制信息)调度数据的传输。SL操作可以支持“两阶段SCI”(two-stage SCI)，其中第一阶段SCI(1 st-stage SCI)可以包含资源预留和/或资源分配等信息，以便于所有正在监测(monitor)SL链路的UE对于资源预留和/或资源分 配情况进行检测(sensing)；第二阶段SCI(2 nd-stage SCI)可以包含其他信息，例如和HARQ反馈相关的信息等。下文中如未特别说明，在单独提到“SCI”时，在适用的情况下，可以指第一阶段SCI，或者第二阶段SCI，或者第一阶段SCI以及第二阶段SCI。 The UE may schedule data transmission through SCI (Sidelink Control Information, direct control information). SL operation can support "two-stage SCI" (two-stage SCI), where the first stage SCI (1 st -stage SCI) can contain information such as resource reservation and/or resource allocation, so that all monitoring (monitor) SL The UE of the link performs sensing (sensing) on resource reservation and/or resource allocation; the second-stage SCI ( 2nd -stage SCI) may include other information, such as information related to HARQ feedback. Hereinafter, unless otherwise specified, when referring to "SCI" alone, where applicable, it may refer to the first stage SCI, or the second stage SCI, or the first stage SCI and the second stage SCI.
第一阶段SCI的格式可以是SCI格式1-A(或者写成“SCI格式1_A”)。下面是SCI格式1-A中可以包含的信息的一些例子：The format of the first stage SCI may be SCI format 1-A (or written as "SCI format 1_A"). The following are some examples of information that can be included in SCI Format 1-A:
●优先级(Priority)。● Priority (Priority).
●频率资源分配(Frequency resource assignment)。● Frequency resource assignment (Frequency resource assignment).
●时间资源分配(Time resource assignment)。● Time resource assignment (Time resource assignment).
●资源预留周期(Resource reservation period)。●Resource reservation period (Resource reservation period).
●DMRS模式(DMRS pattern)。● DMRS pattern (DMRS pattern).
●第二阶段SCI格式(2 nd-stage SCI format)。 ●The second stage SCI format ( 2nd -stage SCI format).
第二阶段SCI的格式可以是SCI格式2-A(或者写成“SCI格式2_A”)，或者SCI格式2-B(或者写成“SCI格式2_B”)。下面是SCI格式2-A和/或SCI格式2-B中可以包含的信息的一些例子：The format of the second-stage SCI may be SCI format 2-A (or written as "SCI format 2_A"), or SCI format 2-B (or written as "SCI format 2_B"). The following are some examples of information that can be included in SCI Format 2-A and/or SCI Format 2-B:
●源层一标识符(Source Layer-1 ID，或者称为Layer-1 Source ID，层一源标识符，或者称为Physical Layer Source ID，物理层源标识符，或者(在上下文清楚的情况下)称为Source ID，源标识符)。Source Layer-1 ID (Source Layer-1 ID, or Layer-1 Source ID, Layer-1 Source Identifier, or Physical Layer Source ID, Physical Layer Source Identifier, or (where the context is clear) ) is called Source ID, source identifier).
●目标层一标识符(Destination Layer-1 ID，或者称为Layer-1 Destination ID，层一目标标识符，或者称为Physical Layer Destination ID，物理层目标标识符，或者(在上下文清楚的情况下)称为Destination ID，目标标识符)。Destination Layer-1 ID, or Layer-1 Destination ID, Layer-1 Destination Identifier, or Physical Layer Destination ID, Physical Layer Destination Identifier, or (where the context is clear ) is called Destination ID, destination identifier).
●HARQ进程标识(HARQ Process ID)，或者说HARQ进程号(HARQ Process Number)。●HARQ process identification (HARQ Process ID), or HARQ process number (HARQ Process Number).
●新数据标识(New Data Indicator，NDI)。● New Data Indicator (New Data Indicator, NDI).
●冗余版本(Redundancy Version，RV)。●Redundancy Version (Redundancy Version, RV).
第一阶段SCI可以携带在PSCCH上。第二阶段SCI可以和要传输的数据一起复用在PSCCH关联的(或者说调度的)PSSCH上。PSCCH及其所关联的PSSCH可以通过一定的方式复用在为SL传输分配的时域和/ 或频域资源上(例如，PSCCH的起始资源块所在的子信道是其所关联的PSSCH的起始子信道。又如，PSCCH的起始资源块是其所关联的PSSCH的起始子信道的起始资源块)。另外，可以认为第一阶段SCI和/或相应的第二阶段SCI调度了PSSCH(或者说调度了PSSCH的传输，或者说调度了PSSCH中携带的TB的传输)。The first stage SCI can be carried on PSCCH. The second stage SCI can be multiplexed on PSCCH-associated (or scheduled) PSSCH together with the data to be transmitted. PSCCH and its associated PSSCH can be multiplexed on the time domain and/or frequency domain resources allocated for SL transmission in a certain way (for example, the subchannel where the starting resource block of PSCCH is located is the starting point of its associated PSSCH). The starting subchannel. For another example, the starting resource block of the PSCCH is the starting resource block of the starting subchannel of its associated PSSCH). In addition, it can be considered that the first stage SCI and/or the corresponding second stage SCI schedules the PSSCH (or schedules the transmission of the PSSCH, or schedules the transmission of the TB carried in the PSSCH).
“PSSCH传输时机”可以是与PSSCH传输和/或接收有关的(例如一个或多个PSSCH传输和/或接收所使用的)一个或多个时域和/或频域和/或码域资源。例如，下面中的一项：A "PSSCH transmission occasion" may be one or more time-domain and/or frequency-domain and/or code-domain resources associated with PSSCH transmission and/or reception (eg, used by one or more PSSCH transmissions and/or receptions). For example, one of the following:
●在一个资源池中的一个时隙。• A time slot in a resource pool.
●在一个资源池中的一个时隙中，与PSSCH传输有关的一个或多个符号。• One or more symbols related to PSSCH transmission in one slot in one resource pool.
●在一个资源池中的一个或多个时隙。• One or more time slots in a resource pool.
●在一个资源池中的一个或多个时隙中，与PSSCH传输有关的一个或多个符号。• One or more symbols related to PSSCH transmission in one or more time slots in a resource pool.
“PSSCH传输时机”也可以称为“PSCCH-PSSCH传输时机”。The "PSSCH transmission occasion" may also be referred to as the "PSCCH-PSSCH transmission occasion".
“PSSCH传输时机”的定义可以只应用于一个资源池(即在每一个资源池内分别定义“PSSCH传输时机”)，也可以应用于多个资源池(例如一个“PSSCH传输时机”可以包括多个资源池内的时域和/或频域和/或码域资源)。The definition of "PSSCH transmission opportunity" can only be applied to one resource pool (that is, "PSSCH transmission opportunity" is defined separately in each resource pool), or it can be applied to multiple resource pools (for example, one "PSSCH transmission opportunity" can include multiple time domain and/or frequency domain and/or code domain resources within the resource pool).
“PSSCH接收时机”可以是与PSSCH传输和/或接收有关的(例如一个或多个PSSCH传输和/或接收所使用的)一个或多个时域和/或频域和/或码域资源。例如，下面中的一项：A "PSSCH reception occasion" may be one or more time-domain and/or frequency-domain and/or code-domain resources associated with (eg used by one or more PSSCH transmissions and/or receptions) PSSCH transmission and/or reception. For example, one of the following:
●在一个资源池中的一个时隙。• A time slot in a resource pool.
●在一个资源池中的一个时隙中，与PSSCH传输和/或接收有关的一个或多个符号。• One or more symbols related to PSSCH transmission and/or reception in a slot in a resource pool.
●在一个资源池中的一个或多个时隙。• One or more time slots in a resource pool.
●在一个资源池中的一个或多个时隙中，与PSSCH传输和/或接收有关的一个或多个符号。• One or more symbols related to PSSCH transmission and/or reception in one or more time slots in a resource pool.
“PSSCH接收时机”也可以称为“PSCCH-PSSCH接收时机”。"PSSCH reception timing" may also be referred to as "PSCCH-PSSCH reception timing".
“PSSCH接收时机”的定义可以只应用于一个资源池(即在每一个 资源池内分别定义“PSSCH接收时机”)，也可以应用于多个资源池(例如一个“PSSCH接收时机”可以包括多个资源池内的时域和/或频域和/或码域资源)。The definition of "PSSCH reception opportunity" can only be applied to one resource pool (that is, the "PSSCH reception opportunity" is defined in each resource pool), or it can be applied to multiple resource pools (for example, a "PSSCH reception opportunity" can include multiple time domain and/or frequency domain and/or code domain resources within the resource pool).
对于一个包含PSCCH和/或PSSCH的SL传输，发送方可以称为TX UE，接收方可以称为RX UE。若HARQ反馈已启用，RX UE可以通过PSFCH反馈与PSCCH和/或PSSCH接收有关的信息(例如称为“HARQ-ACK信息”)。例如，当RX UE在一个资源池中接收一个PSSCH，且相应的SCI中的“HARQ反馈使能/去使能指示符(HARQ feedback enabled/disabled indicator)”的值为1时，所述RX UE在所述资源池中通过PSFCH传输提供HARQ-ACK信息。这种HARQ-ACK信息可以称为“在SL上报告的与SL传输有关的HARQ-ACK信息”。在一些配置下，在SL上报告的与SL传输有关的HARQ-ACK信息可以指示肯定应答(ACK，Acknowledgement，或者Positive Acknowledgement)，例如表示可以正确解码相应的PSCCH和/或PSSCH所携带的数据，或者指示否定应答(NACK，或者NAK，Negative Acknowledgement)，例如表示无法正确解码相应的PSCCH和/或PSSCH所携带的数据；在另一些配置下，在SL上报告的与SL传输有关的HARQ-ACK信息可以只指示NACK(例如在可以正确解码相应的PSCCH和/或PSSCH所携带的数据时，不发送任何HARQ反馈；在无法正确解码相应的PSCCH和/或PSSCH所携带的数据时，发送NACK)。“ACK”和“NACK”可以称为HARQ-ACK值(HARQ-ACK value)。For an SL transmission containing PSCCH and/or PSSCH, the sender may be referred to as a TX UE and the receiver may be referred to as an RX UE. If HARQ feedback is enabled, the RX UE may feed back information related to PSCCH and/or PSSCH reception (eg, referred to as "HARQ-ACK information") over the PSFCH. For example, when the RX UE receives one PSSCH in one resource pool, and the value of the "HARQ feedback enabled/disabled indicator" in the corresponding SCI is 1, the RX UE HARQ-ACK information is provided through PSFCH transmission in the resource pool. Such HARQ-ACK information may be referred to as "HARQ-ACK information related to SL transmission reported on SL". In some configurations, the HARQ-ACK information related to SL transmission reported on the SL may indicate an acknowledgment (ACK, Acknowledgement, or Positive Acknowledgement), for example, indicating that the data carried by the corresponding PSCCH and/or PSSCH can be correctly decoded, Or indicate a negative acknowledgment (NACK, or NAK, Negative Acknowledgement), for example, indicating that the data carried by the corresponding PSCCH and/or PSSCH cannot be correctly decoded; in other configurations, reported on the SL HARQ-ACK related to SL transmission The information can only indicate NACK (for example, when the data carried by the corresponding PSCCH and/or PSSCH can be correctly decoded, no HARQ feedback is sent; when the data carried by the corresponding PSCCH and/or PSSCH cannot be correctly decoded, NACK is sent) . "ACK" and "NACK" may be referred to as HARQ-ACK values (HARQ-ACK values).
“PSSCH传输时机”和“PSSCH接收时机”可以认为分别是从TX UE和RX UE的角度定义的，例如，一个“PSSCH传输时机”从RX UE的角度看可以认为就是一个“PSSCH接收时机”，一个“PSSCH接收时机”从TX UE的角度看可以认为就是一个“PSSCH传输时机”。"PSSCH transmission opportunity" and "PSSCH reception opportunity" can be considered to be defined from the perspectives of TX UE and RX UE respectively. For example, a "PSSCH transmission opportunity" can be regarded as a "PSSCH reception opportunity" from the perspective of RX UE, A "PSSCH reception opportunity" can be regarded as a "PSSCH transmission opportunity" from the perspective of the TX UE.
在时域(time domain)，PSFCH资源可以在一个资源池中周期性地出现，例如相应的周期(例如称为“PSFCH周期”或者“PSFCH资源周期”，例如记为
Figure PCTCN2021108596-appb-000032
例如单位为时隙个数)可以通过参数periodPSFCHresource(或者参数sl-PSFCH-Period)进行配置，例如配置为
Figure PCTCN2021108596-appb-000033
或者
Figure PCTCN2021108596-appb-000034
或者
Figure PCTCN2021108596-appb-000035
或者
Figure PCTCN2021108596-appb-000036
)。其 中，
Figure PCTCN2021108596-appb-000037
可以用于指示相应的资源池中没有配置PSFCH资源。例如，若一个资源池未配置PSFCH相关的参数(例如通过sl-PSFCH-Config进行配置的参数)或者参数sl-PSFCH-Config中配置的PSFCH周期为0，则表示所述资源池未配置PSFCH资源。又如，若一个资源池已配置参数sl-PSFCH-Config且参数sl-PSFCH-Config中配置的PSFCH周期大于0时隙，则表示所述资源池已配置PSFCH资源。 In the time domain (time domain), PSFCH resources may appear periodically in a resource pool, such as a corresponding period (for example, referred to as "PSFCH period" or "PSFCH resource period", such as denoted as
Figure PCTCN2021108596-appb-000032
For example, the unit is the number of time slots) can be configured through the parameter periodPSFCHresource (or parameter sl-PSFCH-Period), for example, configure as
Figure PCTCN2021108596-appb-000033
or
Figure PCTCN2021108596-appb-000034
or
Figure PCTCN2021108596-appb-000035
or
Figure PCTCN2021108596-appb-000036
). in,
Figure PCTCN2021108596-appb-000037
It can be used to indicate that there is no PSFCH resource configured in the corresponding resource pool. For example, if a resource pool is not configured with PSFCH-related parameters (for example, parameters configured through sl-PSFCH-Config) or the PSFCH period configured in the parameter sl-PSFCH-Config is 0, it means that the resource pool is not configured with PSFCH resources . For another example, if the parameter s1-PSFCH-Config has been configured in a resource pool and the PSFCH period configured in the parameter s1-PSFCH-Config is greater than 0 timeslots, it means that the resource pool has been configured with PSFCH resources.
一个配置了PSFCH资源的时隙可以称为“PSFCH时隙”。在一个PSFCH时隙内，与PSFCH传输有关的符号可以是所述时隙的最后一个或多个SL符号，例如对于PSFCH格式0，可以是最后三个SL符号(例如符号
Figure PCTCN2021108596-appb-000038

Figure PCTCN2021108596-appb-000044
可以用于PSFCH传输；符号
Figure PCTCN2021108596-appb-000045
可以用作间隔(GAP)符号，或者保护(GUARD)符号。一个PSFCH时隙的其他符号可以用于发送其他SL信号/信道，如PSCCH、PSSCH等。 A time slot in which PSFCH resources are configured may be referred to as a "PSFCH time slot". Within a PSFCH slot, the symbols related to PSFCH transmission may be the last one or more SL symbols of the slot, eg, for PSFCH format 0, may be the last three SL symbols (eg the symbol

在一个已配置PSFCH资源的资源池中，
Figure PCTCN2021108596-appb-000046
个时隙(例如称这样的时隙为“PSSCH时隙”)可以关联到一个PSFCH时隙。例如，所述关联的方式可以如下： In a resource pool with configured PSFCH resources,
Figure PCTCN2021108596-appb-000046
Timeslots (eg, such timeslots are referred to as "PSSCH timeslots") may be associated with one PSFCH timeslot. For example, the association can be as follows:

“PSFCH接收时机”的定义可以只应用于一个资源池(即在每一个资源池内分别定义“PSFCH接收时机”)，也可以应用于多个资源池(例如一个“PSFCH接收时机”可以包括多个资源池内的时域和/或频域和/或码域资源)。The definition of "PSFCH reception opportunity" can only be applied to one resource pool (that is, the "PSFCH reception opportunity" is defined in each resource pool), or it can be applied to multiple resource pools (for example, a "PSFCH reception opportunity" can include multiple time domain and/or frequency domain and/or code domain resources within the resource pool).
“PSFCH传输时机”和“PSFCH接收时机”可以认为分别是从TX UE和RX UE的角度定义的，例如，一个“PSFCH传输时机”从RX UE的角度看可以认为就是一个“PSFCH接收时机”，一个“PSFCH接收时机”从TX UE的角度看可以认为就是一个“PSFCH传输时机”。"PSFCH transmission opportunity" and "PSFCH reception opportunity" can be considered to be defined from the perspectives of TX UE and RX UE respectively. For example, a "PSFCH transmission opportunity" can be regarded as a "PSFCH reception opportunity" from the perspective of RX UE, A "PSFCH reception opportunity" can be regarded as a "PSFCH transmission opportunity" from the perspective of the TX UE.
网络侧(例如基站等)可以为UE(例如，TX UE)配置一个或多个“SL配置许可”(SL configured grant，或者在上下文清楚的情况下简称为SL grant)，例如通过参数sl-ConfiguredGrantConfigList进行配置。每个SL配置许可可以关联周期性的PSSCH传输资源(或者说可以调度周期性的PSSCH传输)，其中，相应的周期可以通过参数sl-PeriodCG进行配置，每个周期内可以分配一个或多个PSSCH传输资源(或者说调度一个或多个PSSCH传输)。SL配置许可可以分为SL配置许可类型-1和SL配置许可类型-2，其中前者关联的资源可以通过半静态的信令(例如RRC信令)配置和/或激活和/或去激活，后者关联的资源可以通过半静态的信令(例如RRC信令)配置，所配置的资源可以动态地(例如通过DCI)激活和/或去激活。The network side (eg, base station, etc.) can configure one or more "SL configuration grants" (SL configured grants, or SL grants for short when the context is clear) for the UE (eg, TX UE), for example, through the parameter sl-ConfiguredGrantConfigList to configure. Each SL configuration grant can be associated with periodic PSSCH transmission resources (or can schedule periodic PSSCH transmission), wherein the corresponding period can be configured through the parameter sl-PeriodCG, and one or more PSSCH can be allocated in each period Transmission resources (or scheduling of one or more PSSCH transmissions). SL configuration permission can be divided into SL configuration permission type-1 and SL configuration permission type-2, where the resources associated with the former can be configured and/or activated and/or deactivated through semi-static signaling (such as RRC signaling), and the latter The associated resources may be configured through semi-static signaling (eg, RRC signaling), and the configured resources may be activated and/or deactivated dynamically (eg, through DCI).
网络侧(例如基站等)可以通过DCI(例如DCI格式3_0)为UE(例 如，TX UE)分配一个或多个PSSCH传输资源(或者说调度一个或多个PSSCH传输)。这种资源分配方式可以称为“动态许可”(dynamic grant)，以区别于“配置许可”(configured grant)。The network side (such as a base station, etc.) may allocate one or more PSSCH transmission resources (or schedule one or more PSSCH transmissions) to a UE (such as a TX UE) through DCI (such as DCI format 3_0). This resource allocation method can be called "dynamic grant" (dynamic grant), to distinguish it from "configured grant" (configured grant).
网络侧(例如基站等)可以为UE(例如，TX UE)提供(例如通过RRC配置提供，又如通过DCI指示)上行资源(例如PUCCH资源，又如PUSCH资源)，用于报告与SL传输有关的HARQ-ACK信息，例如，用于指示SL配置许可或DCI所分配的SL资源上的数据和/或控制信息的发送和/或接收情况。这种HARQ-ACK信息可以称为“在UL上报告的与SL传输有关的HARQ-ACK信息”。The network side (eg, base station, etc.) may provide (eg, provided by RRC configuration, eg, indicated by DCI) uplink resources (eg, PUCCH resources, eg, PUSCH resources) for the UE (eg, TX UE) for reporting related to SL transmission. The HARQ-ACK information, for example, is used to indicate the SL configuration grant or the transmission and/or reception of data and/or control information on the SL resources allocated by the DCI. Such HARQ-ACK information may be referred to as "HARQ-ACK information related to SL transmission reported on UL".
具体地，在UL上报告的与SL传输有关的HARQ-ACK信息可以来自(或者说基于)UE在直行链路上的一个或多个接收和/或发送操作，例如包括下面中的一项或多项：Specifically, the HARQ-ACK information related to the SL transmission reported on the UL may come from (or be based on) one or more receiving and/or transmitting operations of the UE on the direct link, for example including one of the following or Multiple:
●PSFCH接收(PSFCH reception，或者PSFCH receptions)。例如，TX UE在基站通过DCI指示的SL资源上发送PSSCH后，通过在所述PSSCH所在的时隙关联的PSFCH时隙上接收RXUE发送的PSFCH，获取在SL上报告的与SL传输有关的HARQ-ACK信息，并由此确定相应的在UL上报告的与SL传输有关的HARQ-ACK信息。• PSFCH reception (PSFCH reception, or PSFCH receptions). For example, after the TX UE sends the PSSCH on the SL resource indicated by the DCI, the TX UE obtains the HARQ related to the SL transmission reported on the SL by receiving the PSFCH sent by the RX UE on the PSFCH time slot associated with the time slot where the PSSCH is located. - ACK information and thereby determine the corresponding HARQ-ACK information reported on the UL related to the SL transmission.
●无PSFCH接收(absence of PSFCH reception，或者absence of PSFCH receptions)。例如，由于执行其他更高优先级的任务(如执行更高优先级的UL传输)而无法在本来需要接收PSFCH的时隙中执行PSFCH的接收。又如，调度直行链路上的数据传输的SCI指示不需要接收所述数据传输的UE发送HARQ-ACK(例如通过PSFCH携带的HARQ-ACK)。又如，由于未检测到调度相应的PSCCH和/或PSSCH传输的DCI(例如DCI格式3_0)而未发送PSCCH和/或PSSCH，相应地也没有接收PSFCH。又如，相应的资源池中没有配置PSFCH资源。又如，在相应的PSFCH接收时机未检测到PSFCH。● No PSFCH reception (absence of PSFCH reception, or absence of PSFCH receptions). For example, the reception of the PSFCH cannot be performed in a time slot that would otherwise need to receive the PSFCH due to performing other higher priority tasks (eg, performing higher priority UL transmission). As another example, the SCI that schedules the data transmission on the direct link indicates that the UE receiving the data transmission is not required to send a HARQ-ACK (eg, HARQ-ACK carried over the PSFCH). For another example, the PSCCH and/or PSSCH are not transmitted because the DCI scheduling the corresponding PSCCH and/or PSSCH transmission (eg, DCI format 3_0) is not detected, and accordingly the PSFCH is not received. For another example, no PSFCH resource is configured in the corresponding resource pool. For another example, the PSFCH is not detected at the corresponding PSFCH reception occasion.
●PSCCH和/或PSSCH发送。例如，TX UE在基站通过DCI指示的SL资源上发送PSCCH和/或PSSCH。• PSCCH and/or PSSCH transmission. For example, the TX UE sends the PSCCH and/or PSSCH on the SL resource indicated by the base station through the DCI.
●无PSCCH和/或PSSCH发送。例如，由于执行其他更高优先级的任务(如执行更高优先级的UL传输)而无法在本来需要发送PSCCH和/或PSSCH的时隙中执行PSCCH和/或PSSCH的发送。又如，由于未检测到调度相应的PSCCH和/或PSSCH传输的DCI(例如DCI格式3_0)而未发送PSCCH和/或PSSCH。• No PSCCH and/or PSSCH transmission. For example, transmission of PSCCH and/or PSSCH cannot be performed in a time slot where PSCCH and/or PSSCH would otherwise be transmitted due to performing other higher priority tasks (eg, performing higher priority UL transmission). As another example, the PSCCH and/or PSSCH are not sent because the DCI scheduling the corresponding PSCCH and/or PSSCH transmission (eg, DCI format 3_0) is not detected.
作为对比，UE还可以在上行资源(例如PUCCH，又如PUSCH)上报告与DL传输有关的HARQ-ACK信息(相应地，使用与DL传输有关的HARQ-ACK码本)，用于反馈下行链路上的数据和/或控制信息的发送和/或接收情况(例如，发送和/或接收状态；又如，发送和/或接收结果；又如，未执行发送；又如，未执行接收；等等)。这种HARQ-ACK信息可以称为“在UL上报告的与DL传输有关的HARQ-ACK信息”。具体地，在UL上报告的与DL传输有关的HARQ-ACK信息可以来自(或者说基于)UE在下行链路上的一些接收操作，例如包括下面中的一项或多项：In contrast, the UE can also report HARQ-ACK information related to DL transmission on uplink resources (eg, PUCCH, or PUSCH) (correspondingly, use the HARQ-ACK codebook related to DL transmission) for feedback downlink. Sending and/or receiving of data and/or control information on the road (for example, sending and/or receiving status; another example, sending and/or receiving result; another example, not performing transmission; another example, not performing reception; etc). Such HARQ-ACK information may be referred to as "HARQ-ACK information related to DL transmission reported on UL". Specifically, the HARQ-ACK information related to DL transmission reported on the UL may come from (or be based on) some reception operations of the UE on the downlink, for example, including one or more of the following:
●有相应的PDCCH接收的PDSCH接收。• PDSCH reception with corresponding PDCCH reception.
●无相应的PDCCH接收的PDSCH接收(例如，SPS PDSCH接收)。• PDSCH reception without corresponding PDCCH reception (eg SPS PDSCH reception).
●PDCCH接收。例如，PDCCH所携带的DCI中指示“SPS PDSCH释放”指示。又如，PDCCH所携带的DCI中指示“SCell休眠”(SCell dormancy)。• PDCCH reception. For example, the "SPS PDSCH release" indication is indicated in the DCI carried by the PDCCH. For another example, the DCI carried by the PDCCH indicates "SCell dormancy".
在本发明的所有实施例和实施方式中，如未特别说明，“HARQ-ACK信息”指的是在UL上报告的与SL传输有关的HARQ-ACK信息。In all embodiments and implementations of the present invention, "HARQ-ACK information" refers to HARQ-ACK information related to SL transmission reported on the UL, unless otherwise specified.
