的两个资源可以用于传输两个不同的TB。
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”)，或者其他SCI格式。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：
●源层一标识符。
●目标层一标识符。
●HARQ进程标识(HARQ Process ID)，或者说HARQ进程号(HARQ Process Number)。
●新数据标识(New Data Indicator，NDI)。
●冗余版本(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可以是其所关联的PSSCH的起始子信道。又如，PSCCH的起始资源块可以是其所关联 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调度了相应的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)。
若HARQ反馈已启用，则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)”字段的值为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)。
一个RX UE在进行SL接收时，可以只接收满足SL接收条件的PSCCH和/或PSSCH传输。其中，所述SL接收条件可以包括下面中的一项或多项：
●根据SCI确定的源层一标识符和/或目标层一标识符和/或传播类型(例如单播，又如多播，又如广播)的组合与所述RX UE中允许用于接收的源层一标识符和/或目标层一标识符和/或传播类型的一个组合(例如，一个或多个组合中的一个)一致。
●根据SCI和/或相应的MAC PDU子头(subheader)确定的源层二标识符和/或目标层二标识符和/或传播类型与所述RX UE中允许用于接收的源层二标识符和/或目标层二标识符和/或传播类型的一个组合(例如，一个或多个组合中的一个)一致。
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 PCTCN2022084773-appb-000095
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 PCTCN2022084773-appb-000096
或者
Figure PCTCN2022084773-appb-000097
或者
Figure PCTCN2022084773-appb-000098
或者
Figure PCTCN2022084773-appb-000099
)。其中，
Figure PCTCN2022084773-appb-000100
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(例如参数sl-PSFCH-Config，或者所述参数sl-PSFCH-Config中的一个或多个参数)，或者所述参数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所述参数sl-PSFCH-Config且所述参数sl-PSFCH-Config中配置的PSFCH周期的值不是0，则表示所述资源池已配置PSFCH资源。
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，符号
Figure PCTCN2022084773-appb-000101
可以用作间隔(GAP)符号，或者保护(GUARD)符号；符号

Figure PCTCN2022084773-appb-000107
可以用于自动增益控制(Automatic Gain Control，AGC)。一个PSFCH时隙的其他SL符号可以用于发送其他SL信号/信道，如PSCCH、PSSCH等。
在SL资源分配模式2中，可以使用一种或多种方式确定所分配的SL资源。例如，可以使用不同的方式确定“可用资源”(或者“空闲资源”)的集合，然后从所述“可用资源”(或者“空闲资源”)的集合中选择(例如随机选择)一个或多个SL资源用于SL传输。在本发明的实施例和实施方式中，将确定“可用资源”的集合的方式可以称为“资源选择机制”(resource selection mechanism)，或者“资源选择方法”(resource selection method)，或者“资源选择方案”(resource selection scheme)，或者“资源确定机制”(resource determination mechanism)，或者“资源确定方法”(resource determination method)，或者“资源确定方案”(resource determination scheme)，或者“资源分配机制”(resource allocation mechanism)，或者“资源分配方法”(resource allocation method)，或者“资源分配方案”(resource allocation scheme)，或者为上述名称加上前缀“SL”(例如，“SL资源选择机制”)，等等。或者，将确定所分配的SL资源的所有操作的集合称为“资源选择机制”。或者，将确定所分配的SL资源 的部分操作的集合称为“资源选择机制”。
若UE在SL资源分配模式2中使用某个资源选择机制，则可以说UE基于该资源选择机制执行SL资源分配模式2。
SL资源分配模式2所对应的操作可以包括，由高层协议实体(例如MAC层协议实体)在时隙n向物理层协议实体请求根据一个输入参数集合(例如记为P A)确定一个可以从中选择资源的资源子集(例如记为S A)，并由物理层协议实体向高层协议实体(例如MAC层协议实体)报告所述资源子集S A。
所述输入参数集合P A可以包含下面中的一项或多项：
●用于进行资源选择的资源池(例如记为u sel)。例如，所述资源子集S A可以是所述资源池u sel中的一个候选资源集合的一个子集。
●优先级(例如层一优先级，或者说物理层优先级，例如记为prio TX)。
●剩余分组延迟预算(remaining packet delay budget)。
●资源的大小。例如，所述“资源的大小”可以包括每一个资源所占用的子信道个数(例如连续的子信道个数)，例如记为L subCH。又如，所述“资源的大小”可以包括每一个资源所占用的时隙个数(例如连续的时隙个数)，例如记为L slot。可选地，L subCH和/或L slot可以是预定义或配置或预配置的值，例如L slot＝1(此时可以称所述资源为单时隙资源，single-slot resource)。
●资源预留间隔(resource reservation interval)，例如记为P rsvp_TX。
●一个用于重评估(re-evaluation)操作的资源集合，例如记为(r 0，r 1，r 2，...)。
●一个用于抢占(pre-emption)操作的资源集合，例如记为(r′ 0，r′ 1，r′ 2，...)。
为确定所述资源子集S A，可以将集合S A初始化为所有的候选资源组成的集合(例如记为S all)，然后从集合S A中去掉不可用的资源(例如已被其他UE预留的资源)，最后得到的集合S A即为所请求的资源子集。
所述“所有的候选资源组成的集合S all”可以是资源选择窗口(例如，时间间隔[n+T 1，n+T 2]对应的时间窗口)内的、在所述资源池u sel中的、所有对应L subCH个子信道和L slot个时隙的资源的集合，或者该集合的一个子集(例如，只包含可用于传输PSCCH和/或PSSCH的时隙中的资源。例如，若所述资源池u sel中的某个时隙中配置的SL符号集合中，可以用于传输PSCCH和/或PSSCH的SL符号的个数没有对应的PSSCH DMRS模式，则所述时隙无法用于传输PSCCH和/或PSSCH，从而所述时隙中的资源可以不属于所述集合S all)。其中，T 1和T 2可以是由UE确定的、满足一定条件的两个数值，例如，T 1可以与UE的处理能力有关，T 2可以与剩余分组延迟预算有关。
对于一个应用SL资源分配模式2的UE，所述从集合S A中去掉的“不可用的资源”可以包括下面中的一项或多项：
●由于所述UE的传输能力限制而无法在其上进行SL传输的资源。例如，由于所述UE支持的同时进行的传输的个数的限制，导致当所述UE在其他载波上进行传输时无法在所述集合S A对应的SL载波上进行SL传输。又如，由于所述UE支持的载波组合的限制导致当所述UE在其他载波上进行传输时无法在所述集合S A对应 的SL载波上进行SL传输。又如，由于调谐到所述集合S A中的某个资源所需要的时间的要求超出了所述UE的能力而导致所述UE无法在所述资源进行SL传输。
●所述UE通过感测(sensing)操作识别出的不可用的资源。例如，通过监听(monitor)或检测(detect)或接收(receive)SL链路上发送的(例如其他UE发送的)资源预留信息(例如SCI中的资源预留信息)，进而确定的已被预留的资源集合和/或无法确定是否已被预留的资源集合和/或可能产生冲突的资源集合和/或已被分配的资源集合和/或不可用于分配的资源集合，等等。
●其他UE或基站指示的不可用的资源。例如，其他UE通过监听或检测或接收SL链路上发送的资源预留信息(例如SCI中的资源预留信息)，从而确定的已被预留的资源集合和/或无法确定是否已被预留的资源集合和/或可能产生冲突的资源集合和/或已被分配的资源集合和/或不可用于分配的资源集合和/或非优先分配的资源集合，等等。其他UE可以通过SL传输中携带的信令向所述UE指示与这些资源有关的信息。
SL资源分配模式2所对应的操作可以包括，从所述资源子集S A中选择用于一个PSSCH/PSCCH传输(例如PSSCH传输，又如PSCCH传输，又如复用在同一个资源中的PSSCH传输和PSCCH传输)的资源。
SL资源分配模式2所对应的操作可以包括，从所述资源子集S A中选择用于多个PSSCH/PSCCH传输的资源。
SL资源分配模式2所对应的操作可以包括，从所述资源子集S A中选 择用于一个传输块的传输资源，例如从所述资源子集S A中选择用于所述传输块的初始传输以及每一次重传所需的资源。
SL资源分配模式2所对应的操作可以包括，从所述资源子集S A中选择用于多个传输块的传输资源，例如从所述资源子集S A中选择用于所述多个传输块中的每一个传输块的初始传输以及每一次重传所需的资源。
在SL资源分配模式2中，在从所述资源子集S A中选择资源时，可以使用“随机选择”的方式，例如，按等概率的方式从所述资源子集S A中选择一个资源。
若一个资源选择机制通过感测操作识别出不可用的资源，则可以认为该资源选择机制是一种“基于感测的资源选择机制”。其中，感测操作可以是“全感测”(full sensing，或者简称为“感测”，sensing)，例如，UE必须监听感测窗口(例如，时间间隔
Figure PCTCN2022084773-appb-000108
对应的时间窗口，和/或按其他方式定义的时间窗口)内的属于(或者，可以属于)所述资源池u sel的、除了因为一些例外情况而无法监听的那些时隙(例如，由于半双工限制而无法在执行SL传输时监听的那些时隙)和/或一些特殊时隙(例如，无法用于传输PSCCH和/或PSSCH的时隙)以外的所有时隙；其中，T 0可以通过高层参数(例如参数sl-SensingWindow)进行配置，
Figure PCTCN2022084773-appb-000109
可以与UE的处理能力有关。相应的资源选择机制可以称为“基于全感测的资源选择机制”，或者“基于全感测的资源选择”，或者简称为“全感测”，或者在不引起混淆的情况下简称为“基于感测的资源选择机制”，或者“基于感测的资源选择”，或者简称为“感测”。
感测操作也可以是“部分感测”(partial sensing)，例如，UE只需要 监听所述感测窗口内的属于(或者，可以属于)所述资源池u sel的部分时隙(例如，周期性出现的部分时隙)。相应的资源选择机制可以称为“基于部分感测的资源选择机制”，或者“基于部分感测的资源选择”，或者简称为“部分感测”。
若一个资源选择机制不涉及(或者不执行)感测操作，则可以认为该资源选择机制是一种“不基于感测的资源选择机制”。例如，所述集合S A可以等于所述“所有的候选资源组成的集合S all”，或者等于在所述“所有的候选资源组成的集合S all”中排除一些特殊的资源而得到的集合。其中，所述特殊的资源可以包括下面中的一项或多项：
●无法用于传输PSCCH/PSSCH的时隙中的资源。
●由于所述UE的传输能力限制而无法在其上进行SL传输的资源。
●其他UE或基站指示的不可用的资源。
相应的资源选择机制可以称为“随机资源选择”(random resource selection)，或者简称为“随机选择”(random selection)，或者，称为“不基于感测的随机资源选择”。
另外，也可以存在“基于感测的随机资源选择”。例如，在基于感测的资源选择机制中，若由于某种原因无法应用感测结果，或者只是应用部分的感测结果，则可以认为是“基于感测的随机资源选择”。
不同的UE可以支持不同的资源选择机制集合。例如，所有UE都支持“随机资源选择”。又如，一部分UE只支持“全感测”和“随机资源选择”。又如，一部分UE只支持“部分感测”和“随机资源选择”。又如，一部分UE支持“全感测”、“部分感测”和“随机资源选择”。 UE支持的资源选择机制的集合可以记为M cap。
在各种SL资源选择机制中，可以认为“全感测”对电量(或能源)的消耗比较大，比较适用于对能耗不敏感的UE(例如在V2V通信中，安装在汽车上的UE)，而“部分感测”、“随机资源选择”等的能耗消耗相对比较小，比较适用于对能耗敏感的UE和/或对能耗敏感的通信场景(例如V2P通信中“Pedestrian”对应的手持设备)。另一方面，“随机资源选择”可以作为一种异常处理机制或者其他资源选择机制(例如“全感测”)的一种回退机制(例如，在V2V通信中，当暂无感测结果可用时，可以从“全感测”回退至“随机资源选择”)，所以，“随机资源选择”也可以应用于对能耗不敏感的UE。当然，“部分感测”、“随机资源选择”等SL资源选择机制的缺点是增加了不同UE选择的资源发生冲突的概率。
“部分感测”、“随机资源选择”等SL资源选择机制可以作为“SL节能”特性的一部分应用到SL通信中。例如，只有在使能(或者说打开，或者说配置)“SL节能”的情况下，才可以使用“部分感测”，等等。
在使能“SL节能”的情况下，UE可以处于多个与“SL节能”有关的状态(例如称为SL状态，或者SL模式，或者SL通信方式，等等)中的一个，例如：
●第一SL状态。例如，第一SL状态可以是“SL非节能状态”，例如，处于这一SL状态的UE对电量(或能源)的消耗不敏感，相应地，所使用的资源选择机制不需要特别考虑电量(或能源)的消耗。第一SL状态也可以称为“第一SL模式”，或“第一 SL通信方式”，等等。SL非节能状态也可以称为“SL非节能模式”，或“SL非节能通信方式”，等等。SL非节能通信方式的一个例子可以是一些特定的V2X通信方式(例如，V2V)。
●第二SL状态。第二SL状态可以是“SL节能状态”，例如，处于这一SL状态的UE对电量(或能源)的消耗比较敏感或者非常敏感，相应地，所使用的资源选择机制需要考虑电量(或能源)的消耗，例如，避免或减少使用耗电量高的资源选择机制。第二SL状态也可以称为“第二SL模式”，或“第二SL通信方式”，等等。SL节能状态也可以称为“SL节能模式”，或“SL节能通信方式”，等等。SL节能通信方式的一个例子可以是一些特定的V2X通信方式(例如，V2P)。SL节能通信方式的另一个例子可以是用于公共安全的SL通信方式。
可以通过一个高层协议参数(例如称为sl-powerSavingConfig)使能(或者说“打开”，或者说“配置”)或去使能(或者说关闭)“SL节能”。例如，若所述参数sl-powerSavingConfig不存在(或者说未配置)，则表示“SL节能”未使能或已去使能。又如，若所述参数sl-powerSavingConfig存在(或者说已配置)，则表示“SL节能”已使能。又如，若所述参数sl-powerSavingConfig(或所述参数sl-powerSavingConfig对应的信息元素中的某个参数)的取值为一个预定义的值(例如，“disabled”，“false”等)，则表示“SL节能”未使能或已去使能。又如，若所述参数sl-powerSavingConfig(或所述参数sl-powerSavingConfig对应的信息元素中的某个参数)的取值为一个预定义的值(例如， “enabled”，“true”等)，则表示“SL节能”已使能。
若“SL节能”未使能，可以认为UE总是处于第一SL状态。
UE支持的资源选择机制的集合M cap可以与所述UE所处的SL状态有关。例如，若UE处于第一SL状态，则所述集合M cap等于集合M cap，1；又如，若所述UE处于第二SL状态，则所述集合M cap等于集合M cap，2。其中，可选地，所述集合M cap，1和所述集合M cap，2可以相同，也可以不同。例如，所述集合M cap，1是{全感测}；又如，所述集合M cap，1是{全感测，随机资源选择}；又如，所述集合M cap，1是{全感测，部分感测，随机资源选择}；又如，所述集合M cap，2可以是{随机资源选择}；又如，所述集合M cap，2可以是{部分感测，随机资源选择}。
在SL通信中可以支持UE间协作(inter-UE coordination)功能，例如，用于两个或更多个UE之间在资源(例如SL资源)分配和/或预留和/或指示上的协作。具体地，例如，一个UE(例如，称为UE A)可以向一个或多个其他UE(例如，统一称为UE B)传输“UE间协作消息”，其中可以指示一个(或者多个)资源集合。
一个从UE A向UE B传输的UE间协作消息中指示的每个资源可以对应一个“资源类型”(或者“资源状态”，或者“资源特征”，或者“资源用途”)，例如，下面中的一项：
●“已预留的资源”(或者“正在预留的资源”，或者“将要预留的资源”，或者“用于预留的资源”，或者“已分配的资源”，或者“正在分配的资源”，或者“将要分配的资源”，或者“用于分配的资源”)。例如，所述资源已被所述UE A预留(或者 分配)。具体地，所述资源可以是所述UE A为一个特定的UE预留的，例如所述UE A自己，又如所述UE B。
●“已释放的资源”(或者“正在释放的资源”，或者“将要释放的资源”，或者“用于释放的资源”)。例如，所述UE A希望释放其在先前传输的SCI中预留的资源，其中，释放所述资源的原因可以是，所述资源是为一个TB的若干次重传中的一次(例如，最后一次)所选择的资源，而所述UE A在所述资源对应的时隙到来之前已经接收到了对所述TB的确认)。
●“有冲突的资源”。例如，所述UE A检测到所述资源所在的时隙和/或一个或多个子信道上存在资源预留冲突。其中，可选地，所述“冲突”可以是一个已经过去的时隙上的冲突，相应的冲突检测可以称为“冲突后检测”(post-collision detection)；可选地，所述“冲突”可以是一个将来的时隙上的冲突(或者称为“潜在冲突”)，相应的冲突检测可以称为“冲突前检测”(pre-collision detection)。
●“优先资源”。例如，所述UE A希望所述UE B在进行资源选择时选择(或优先选择)所述资源(例如，当所述UE B向所述UE A进行SL传输时)。
●“非优先资源”。例如，所述UE A希望所述UE B在进行资源选择时排除(或优先排除)所述资源(例如，当所述UE B向所述UE A进行SL传输时)。
一个UE间协作消息可以由传输所述UE间协作消息的UE自主触发。 例如，若UE A检测到UE B1和UE B2分别指示(或者预留，或者分配)的资源存在冲突，则所述UE A可以传输一个UE间协作消息，用于指示所述存在冲突的资源。其中，所述UE间协作消息可以用广播或组播的方式传输，或者用单播的方式分别向UE B1和UE B2传输。
一个UE间协作消息可以由一个或多个其他UE传输的“UE间协作请求消息”触发。此时，所述UE间协作消息又可以称为“UE间协作响应消息”。例如，UE B向UE A传输“UE间协作请求消息”，而UE A则向UE B传输“UE间协作响应消息”作为回应。
一个UE间协作消息可以是一个物理层消息。例如，所述UE间协作消息可以包含在SCI(例如，第一阶段SCI；又如，第二阶段SCI)中。又如，所述UE间协作消息可以复用在PSSCH中(例如，和第二阶段SCI和/或SL-SCH复用在同一个PSSCH传输中)。又如，所述UE间协作消息可以复用在PSCCH中(例如，和第一阶段SCI复用在同一个PSCCH传输中)。
一个UE间协作消息可以是一个高层(例如MAC层，又如RRC层)消息。例如，所述UE间协作消息可以携带在一个MAC CE中。又如，所述UE间协作消息可以是一个RRC消息。
一个UE间协作请求消息可以是一个物理层消息。例如，所述UE间协作请求消息可以包含在SCI(例如，第一阶段SCI；又如，第二阶段SCI)中。又如，所述UE间协作请求消息可以复用在PSSCH中(例如，和第二阶段SCI和/或SL-SCH复用在同一个PSSCH传输中)。又如，所述UE间协作请求消息可以复用在PSCCH中(例如，和第一阶段SCI复用 在同一个PSCCH传输中)。
一个UE间协作请求消息可以是一个高层(例如MAC层，又如RRC层)消息。例如，所述UE间协作请求消息可以携带在一个MAC CE中。又如，所述UE间协作请求消息可以是一个RRC消息。
在UE间协作消息中指示的协作资源可以通过一个或多个在SL链路上检测到的SCI(例如，在“感测”等操作中检测到的一个或多个SCI)确定，例如，通过多个SCI确定一个资源已被多个其他UE预留；又如，通过多个SCI确定多个其他UE预留的资源互相重叠(例如在一个或多个RE上重叠)。
可以通过一个高层协议参数(例如称为sl-ueCoordConfig)打开(或者说“使能”，或者说“配置”)或关闭(或者说去使能)UE间的协作功能。例如，若所述参数sl-ueCoordConfig不存在(或者说未配置)，则表示UE间的协作功能未打开。又如，若所述参数sl-ueCoordConfig存在(或者说已配置)，则表示UE间的协作功能已打开。又如，若所述参数sl-ueCoordConfig(或所述参数sl-ueCoordConfig对应的信息元素中的某个参数)的取值为一个预定义的值(例如，“disabled”，“false”等)，则表示UE间的协作功能未打开。又如，若所述参数sl-ueCoordConfig(或所述参数sl-ueCoordConfig对应的信息元素中的某个参数)的取值为一个预定义的值(例如，“enabled”，“true”等)，则表示UE间的协作功能已打开。
