下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的副链路传输处理方法、副链路传输配置方法、装置、终端、网络侧设备和存储 介质进行详细地说明。
请参见图2，图2是本申请实施例提供的副链路传输处理方法的流程图。如图2所示，副链路传输处理方法包括以下步骤：

上述物理副链路第一信道包括物理副链路控制信道(Physical SideLink Control Channel，PSCCH)和物理副链路共享信道(Physical SideLink Shared Channel，PSSCH)中的至少一项，为了描述方便，物理副链路第一信道可表示为PSCCH/PSSCH。
在本申请实施例中，考虑到系统可引入子时隙粒度的副链路传输，终端在副链路传输处理过程中，可先确定物理副链路第一信道的传输粒度，而后再进行副链路资源选择以及副链路传输，这样，终端可根据物理副链路第一信道的传输粒度，采用合适的处理方式进行副链路资源选择以及副链路传输，从而能够提高副链路传输性能。
本申请实施例涉及副链路资源选择、副链路传输和副链路反馈等多个方面，以下对副链路资源选择、副链路传输等方面的实施方式进行说明。
在一些实施例中，所述终端进行副链路资源选择之前，所述方法还包括：
所述终端确定资源选择触发时刻和监听窗口，所述监听窗口的结束位置与目标时隙的开始位置的间隔大于预设值，所述目标时隙为所述资源选择触 发时刻所在的时隙；
所述终端在所述监听窗口的结束位置之前，对PSCCH进行检测，以得到检测结果；
所述终端进行副链路资源选择，包括：
所述终端根据所述检测结果，在所述资源选择触发时刻之后进行副链路资源选择。
相关技术中，副链路资源的分配方式有两种：一种是基于基站调度，另一种是基于终端自主选择。对于终端自主选择的资源分配方式，终端在(预)配置的资源池中选择可用的传输资源。终端在资源选择之前先进行信道监听，根据信道监听结果选择出干扰较小的资源集合，再从资源集合中随机选择用于传输的资源。具体的工作方式如下：终端在资源选择被触发后，首先确定资源选择窗口，资源选择窗口的下边界在资源选择触发时刻之后的T1时间，资源选择窗口的上边界在资源选择触发时刻之后的T2时间，其中T1是终端自主选择的，T1的值不大于Tproc,1(资源选择处理时间)，T2是终端实现的方式在其传输块(Transport Block，TB)传输的包延时预算(Packet Delay Budget，PDB)内选择的值，T2不早于T1。终端在资源选择之前，需要确定资源选择的备选资源结合(candidate resource set)，其中备选资源子信道(sub-channel)的个数由媒体接入控制(Medium Access Control，MAC)层确定，终端根据资源选择窗口内的资源上预估的参考信号接收功率测量值(Reference Signal Received Power，RSRP)与相应的RSRP门限(RSRP threshold)进行对比，如果RSRP高于RSRP threshold，那么对该资源进行资源排除，不能纳入备选资源集合。进行资源排除后资源选择窗口内剩余的资源组成备选资源集合。备选资源集合中的资源在资源选择窗口中的资源的占比要不少于x％，如果少于x％，RSRP threshold需要按照步进值(如3dB)进行增加，再进行上述资源排除操作，直到可以选出不少于x％的资源。备选资源集合确定后，终端随机在备选资源集合中选择传输资源，所选资源的个数根据MAC层的决策确定。上述过程中，终端可通过监听(sensing)窗口中的PSCCH/PSSCH预估RSRP，监听窗口可在资源选择触发时刻的Tproc,0时间之前，Tproc,0为监听结果处理时间。
如前所述，系统可引入子时隙粒度的副链路传输，相比于时隙粒度的副链路传输，终端需要更频繁地处理子时隙，例如，如果一个时隙内存在多个子时隙，则终端解调子时隙的PSCCH的个数会增加，终端处理PSCCH的时长会延后。该实施方式中，终端进行副链路资源选择之前，可基于物理副链路第一信道的传输粒度确定出合适的资源选择触发时刻和监听窗口。
终端确定的资源选择触发时刻可能是某个时隙的开始位置(或结束位置)，也可能是某个时隙的某个子时隙的开始位置(或结束位置)。相应的，终端确定的监听窗口的结束位置可能是某个时隙的开始位置(或结束位置)，也可能是某个时隙的某个子时隙的开始位置(或结束位置)。终端确定资源选择触发时刻和监听窗口可以是在不同的时机下确定，也可以是在同一时机下确定，本申请实施例对此不作限定。
该实施方式中，终端通过确定合适的资源选择触发时刻和监听窗口，能够提高副链路传输性能。
在一些实施例中，所述副链路资源选择的粒度为时隙粒度；
所述监听窗口的结束位置包括以下任一项：
所述目标时隙之前的第N个时隙中的第i个子时隙的开始位置；
所述目标时隙之前的第N个时隙中的第i个子时隙PSCCH的结束位置；
所述目标时隙之前的第N个时隙中的第i个子时隙PSCCH的开始位置；
所述目标时隙之前的第N个时隙的时隙PSCCH的结束位置；
其中，所述N和所述i中的至少一者基于协议约定或由网络配置或预配置；所述子时隙PSCCH为以子时隙粒度传输的PSSCH所关联的PSCCH，所述时隙PSCCH为以时隙粒度传输的PSSCH所关联的PSCCH。
相关技术中，终端可对监听窗口的结束位置之前的PSCCH进行检测，由于系统可引入子时隙粒度的副链路传输，因此，在监听窗口的结束位置之前的PSCCH既可以包括时隙PSCCH，还可以包括子时隙PSCCH，在包括子时隙PSCCH的情况下，终端处理子时隙PSCCH的处理时间可能不足，例如，假设监听窗口的最后一个或多个时隙存在子时隙PSCCH，则可能由于终端硬件条件的限制而导致终端处理子时隙PSCCH的处理时间不足。
鉴于此，该实施方式中，可以对监听窗口的结束位置进行适当地调整， 以解决终端处理子时隙PSCCH的处理时间不足的问题。
在一些示例中，监听窗口的结束位置可以是目标时隙之前的第N个时隙中的第i个子时隙的开始位置，将监听窗口的结束位置设置为子时隙的开始位置，可以确保监听窗口内的第N个时隙不包含子时隙PSCCH，解决了终端处理子时隙PSCCH的处理时间不足的问题。
假设相关技术中监听窗口的结束位置为slot n-Tproc,0(对应图3中A所在的位置，即slot n-1的开始位置或slot n-2的结束位置)，则该实施方式中，监听窗口的结束位置为slot n-Tproc,0’(对应图3中A’所在的位置)，其中，Tproc,0’基于sub-slot为粒度定义，例如Tproc,0’＝Tproc,0+number of sub-slot。
在另一些示例中，监听窗口的结束位置可以是目标时隙之前的第N个时隙中的第i个子时隙PSCCH的结束位置，将监听窗口的结束位置设置为第i个子时隙PSCCH的结束位置，可以确保该监听窗口内的第N个时隙不包含第i+1个子时隙PSCCH及以后的子时隙PSCCH，从而解决了终端处理子时隙PSCCH的处理时间不足的问题。
假设相关技术中监听窗口的结束位置为slot n-Tproc,0(对应图4中A所在的位置，即slot n-1的开始位置或slot n-2的结束位置)，则该实施方式中，监听窗口的结束位置为slot n-2中的第一个子时隙PSCCH的结束位置(对应图4中A’所在的位置)。
在另一些示例中，监听窗口的结束位置可以是目标时隙之前的第N个时隙中的第i个子时隙PSCCH的开始位置，将监听窗口的结束位置设置为第i个子时隙PSCCH的开始位置，可以确保该监听窗口内的第N个时隙不包含第i个子时隙PSCCH及以后的子时隙PSCCH，从而解决了终端处理子时隙PSCCH的处理时间不足的问题。
假设相关技术中监听窗口的结束位置为slot n-Tproc,0(对应图5中A所在的位置，即slot n-1的开始位置或slot n-2的结束位置)，则该实施方式中，监听窗口的结束位置为slot n-2中的第一个子时隙PSCCH的开始位置(对应图5中A’所在的位置)。
在又一些示例中，监听窗口的结束位置可以是目标时隙之前的第N个时隙的时隙PSCCH的结束位置，将监听窗口的结束位置设置为时隙PSCCH的 结束位置，可以确保该监听窗口内的第N个时隙仅包含时隙PSCCH而不包含子时隙PSCCH，从而解决了终端处理子时隙PSCCH的处理时间不足的问题。
假设相关技术中监听窗口的结束位置为slot n-Tproc,0(对应图6中A所在的位置，即slot n-1的开始位置或slot n-2的结束位置)，则该实施方式中，监听窗口的结束位置为slot n-2中的时隙PSCCH的结束位置(对应图6中A’所在的位置)。
该实施方式，通过对监听窗口的结束位置进行适当地调整，能够解决终端处理子时隙PSCCH的处理时间不足的问题。
需要说明的是，监听窗口的结束位置可以是由终端自主确定，也可以是由终端基于协议约定或网络侧配置或预配置确定。该实施方式既可以适用于以时隙为时域粒度的副链路传输，也可以适用于以子时隙为时域粒度的副链路传输。
在一些实施例中，所述副链路资源选择的粒度为时隙粒度；
在所述监听窗口的最后M个时隙中包括第一PSCCH的情况下，所述方法还包括：
所述终端确定是否对所述第一PSCCH进行检测；
其中，所述第一PSCCH为以子时隙粒度传输的PSSCH所关联的PSCCH，M为大于或等于1的整数。
该实施方式中，如果监听窗口的最后M个时隙中包括第一PSCCH(即子时隙PSCCH)，则终端可以确定是否对第一PSCCH进行检测。
作为示例，如图7所示，假设slot n-2为监听窗口的最后一个时隙，该时隙中包括子时隙PSCCH，则终端可确定是否对该子时隙PSCCH进行检测，以解决终端处理子时隙PSCCH的处理时间不足的问题。
在一些实施例中，所述终端确定是否对所述第一PSCCH进行检测，包括以下至少一项：
所述终端基于终端实现，确定是否对所述第一PSCCH进行检测；
所述终端基于协议约定或网络配置信息或预配置信息，确定是否对所述第一PSCCH进行检测；
所述终端根据所述第一PSCCH至所述目标时隙的开始位置的时长，确定是否对所述第一PSCCH进行检测。
作为示例，如图7所示，终端可以确定slot n-Tproc,0的前一个slot(即slot n-2)内的子时隙PSCCH不需要检测，或者，靠近slot n的某些子时隙PSCCH不需要检测，或者基于终端实现(UE implementation)决定是否检测子时隙PSCCH。或者，终端可以根据子时隙PSCCH到slot n的时长，决定是否检测子时隙PSCCH，例如，当时长大于预设时间单元(预设时间单元可以包括slot、sub-slot、ms(即毫秒)、μs(即微秒)或symbol等等)时，终端检测子时隙PSCCH，否则，终端不检测子时隙PSCCH。
需要说明的是，该实施方式既可以适用于以时隙为时域粒度的副链路传输，也可以适用于以子时隙为时域粒度的副链路传输。
在一些实施例中，所述副链路资源选择的粒度为子时隙粒度，且所述副链路传输的粒度为子时隙粒度；
所述终端进行副链路资源选择，包括：
所述终端根据预设的编号规则，以子时隙粒度对时域资源进行编号；
所述终端根据时域资源的编号，进行副链路资源选择。
该实施方式中，副链路资源选择的粒度以sub-slot为粒度定义，例如，Tproc,0以及Tproc,1均以sub-slot为粒度定义，以精确地保证PSCCH/PSSCH的处理时间(processing time)需求。
终端在进行副链路资源选择时，可以根据预设的编号规则，以sub-slot为时域粒度对时域资源进行索引编号，并根据时域资源的索引编号，进行副链路资源选择。
在一些实施例中，所述终端根据时域资源的编号，进行副链路资源选择，包括：
所述终端根据时域资源的编号，确定副链路资源选择时间参数；
所述终端根据所述副链路资源选择时间参数，进行副链路资源选择；
其中，所述副链路资源选择时间参数包括以下至少一项：
监听窗口的开始位置；
监听窗口的结束位置；
资源选择窗口的开始位置；
资源选择触发时刻；
资源重评估(re-evaluation)时刻；
资源抢占检查(pre-emption check)时刻。
例如，监听窗口的结束位置可以是slot n-Tproc,0’，Tproc,0’基于sub-slot为粒度定义，或者，re-evaluation时刻可以是至少在待传输或待预留的sub-slot前的T个sub-slot，或者，pre-emption check时刻可以是至少在待传输或待预留的sub-slot前的K个sub-slot。
以上为副链路资源选择和副链路传输等方面的相关实施方式，以下对副链路反馈的相关实施方式进行说明。
在一些实施例中，所述方法还包括：
所述终端确定第一物理副链路反馈信道(Physical SideLink Feedback Channel，PSFCH)，所述第一PSFCH为第一PSSCH对应的PSFCH，所述第一PSSCH为以子时隙粒度传输的PSSCH。
如前所述，系统可引入子时隙粒度的副链路传输，如果子时隙粒度的PSCCH/PSSCH传输和时隙粒度的PSCCH/PSCCH传输同时存在，则终端需要区分相应的PSFCH资源，否则终端在解调PSFCH时可能产生误解。
该实施方式中，终端能够确定以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH反馈资源，从而确保终端在正确的PSFCH资源上进行副链路混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)反馈，从而能够提高副链路传输性能。
在一些实施例中，所述终端确定第一PSFCH，包括以下至少一项：
所述终端根据所述第一PSSCH的时隙标识，确定所述第一PSFCH；
所述终端根据所述第一PSSCH的编号，确定所述第一PSFCH，所述第一PSSCH的编号与所述第一PSFCH存在预设映射关系。
网络侧设备可以独立配置sub-slot PSCCH/PSSCH的PSFCH资源，也可以统一配置PSFCH资源(即sub-slot PSCCH/PSSCH与slot PSCCH/PSSCH配有统一的PSFCH资源)。
该实施方式中，无论网络侧设备是独立配置sub-slot PSCCH/PSSCH的 PSFCH资源，还是统一配置PSFCH资源，终端均可按照版本16(Rel-16)中约定的PSFCH反馈资源确定流程来确定第一PSFCH，即：根据PSCCH/PSSCH的时隙标识，确定第一PSFCH，具体的，确定第一PSFCH的时域(occasion)和频域(如PSFCH RB set等)。
而如果统一配置PSFCH资源，终端可以根据第一PSSCH的编号确定第一PSFCH，第一PSSCH的编号与第一PSFCH存在预设映射关系。具体示例如下：
对一组slot PSCCH/PSSCH资源和sub-slot PSCCH/PSSCH资源进行逻辑编号。编号的方式例如可以是：slot PSCCH/PSSCH编号为#1到#n，sub-slot PSCCH/PSSCH编号为#n+1到#2*n，如果slot内有多个sub-slot，sub-slot继续编号#2*n+1到#3*n，依次类推。编号的方式例如还可以是：一个slot PSCCH/PSSCH编号为#m，slot内的sub-slot PSCCH/PSSCH编号为#m+1，如果slot内有多个sub-slot，sub-slot继续编号#m+2，依此类推，再继续下一个slot的编号。第一PSSCH的编号与第一PSFCH存在的映射关系例如可以是：第一个编号的PSCCH/PSSCH资源对应到一个PRB#1到PRB#n的PSFCH资源，第二个编号的PSCCH/PSSCH资源对应到一个PRB#n+1到PRB#2*n的PSFCH，依此类推。其中，PRB是指物理资源块(Physical Resource Block)。
在一些实施例中，所述终端确定第一PSFCH，包括：
在所述第一PSSCH传输的数据为有效数据的情况下，所述终端确定第一PSFCH。
如果第一PSSCH传输无效数据(dummy data)，则终端无需进行PSFCH反馈，也就无需确定第一PSFCH。
在一些实施例中，所述方法还包括：
所述终端获取所述第一PSFCH的配置参数，所述第一PSFCH的配置参数通过协议约定或通过网络侧设备配置或预配置，所述配置参数包括资源配置参数和反馈时序配置参数中的至少一项；
所述终端确定第一PSFCH，包括：
所述终端根据所述第一PSFCH的配置参数，确定所述第一PSFCH。
在一些实施例中，所述第一PSFCH的配置参数与第二PSFCH的配置参 数互相独立，所述第二PSFCH为第二PSSCH对应的PSFCH，所述第二PSSCH为以时隙粒度传输的PSSCH。
在一些实施例中，所述第一PSFCH的配置参数包括以下至少一种：
所述第一PSFCH的时域资源配置参数；
所述第一PSFCH的频域资源配置参数；
所述第一PSFCH的码域资源配置参数；
所述第一PSSCH与所述第一PSFCH的最小时间间隔。
以下就第一PSFCH(即以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH)和第二PSFCH(即以slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH)的资源配置参数的两种主要情况进行具体说明。
情况一：以slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH，与以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH映射到不相同的PSFCH occasion。即独立配置以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH occasion，例如，PSCCH/PSSCH与对应的PSFCH occasion的最小间隔、PSFCH周期和PSFCH周期开始的偏移量(offset)中的至少一项独立配置。
可选地，以slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH，与以sub-slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH映射到不同的PSFCH资源块集(PSFCH RB set)。即独立配置以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH的资源块集(Resource block set，RB set)。
情况二：以slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH，与以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH映射到相同的PSFCH occasion。
在此情况下，以slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH，与以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH映射到相同的PSFCH RB set。可选地，独立配置以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH的码域资源(如循环移位(cyclic shift,CS))。或者，以slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH，与以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH映射到相同的码域资源(如CS)。
或者，以slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH，与以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH映射到不同的PSFCH RB set。即独立配置以sub-slot为基本单元传输的PSCCH/PSSCH对应的PSFCH的RB set。
上述两种情况各有优势，其中，情况一能够有效的处理sub-slot PSCCH/PSSCH解调带来的额外处理时间开销，情况二能够节省PSFCH资源开销，避免PSFCH与PSSCH的半双工冲突以及自动增益控制(Automatic Gain Control，AGC)变动等问题，前提是终端额外处理sub-slot PSCCH/PSSCH的时间和处理slot PSCCH/PSSCH的时间在相当的时间量级。额外的，情况一和情况二中，以slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH资源和以sub-slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH资源的资源配置参数可以相同，这能够节省配置不同参数的信令的开销。情况二中，独立配置以sub-slot为基本时间单元传输的PSCCH/PSSCH对应的PSFCH资源，还能够降低PSFCH的碰撞概率，即能够降低以不同的基本时间单元传输的PSCCH/PSSCH对应的PSFCH发生碰撞的概率，提高PSFCH的发射效率。
以下就第一PSFCH和第二PSFCH的反馈时序配置参数的情况进行具体说明：
以slot为基本时间单元传输的PSCCH/PSSCH资源对应于其至少P个slot后的第一个PSFCH occasion(即第二PSSCH与第二PSFCH的最小时间间隔为P个slot)，以sub-slot为基本时间单元传输的PSCCH/PSSCH资源对应于其至少Q个slot或Q个sub-slot后的第一个PSFCH occasion(即第一PSSCH与第一PSFCH的最小时间间隔为Q个slot或Q个sub-slot)。P和Q的值可以分别预配置。
在一些实施例中，所述副链路传输的粒度为子时隙粒度；
所述终端确定第一PSFCH，包括：
所述终端根据预设的编号规则，以子时隙粒度对时域资源进行编号；
所述终端根据时域资源的编号，确定第一PSFCH反馈资源。
该实施方式中，副链路传输的粒度为子时隙粒度，例如，PSSCH到PSFCH的反馈间隔以sub-slot粒度定义，以精确地保证PSCCH/PSSCH的处理时间需 求。
终端可以以sub-slot为时域粒度对时域资源进行索引编号，HARQ反馈相关的时间参数可以根据该索引编号确定，从而终端可基于HARQ反馈相关的时间参数确定第一PSFCH反馈资源。HARQ反馈相关的时间参数例如可以包括：第一PSFCH周期、第一PSFCH开始的偏移量(offset)、PSFCH反馈的occasion等等。
综上，本申请实施例通过以上实施方式，能够使终端适应sub-slot为粒度的副链路传输处理的时间要求，从而能够提高副链路传输性能。
