为便于理解本申请实施例的技术方案，对本申请相关的多传输接收点(Transmission Reception Point，TRP)的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输方案进行说明。
NR系统中引入了基于多个TRP的下行和上行的非相干传输。其中，TRP之间的backhaul连接可以是理想的或者非理想的，理想的backhaul下TRP之间可以快速动态的进行信息交互，非理想的backhaul下由于时延较大TRP之间只能准静态的进行信息交互。在下行非相干传输中，多个TRP可 以采用不同的控制信道独立调度一个终端的多个PDSCH传输，也可以采用同一个控制信道调度不同TRP的传输，其中不同TRP的数据采用不同的传输层，后者只能用于理想backhaul的情况。
在一些场景中，UE可以向两个TRP以时分复用(time-division multiplexing，TDM)的方式发送PUSCH。
在一些场景中，网络设备可以通过单下行控制信息(Downlink Control Information，DCI)调度终端设备向两个TRP传输PUSCH。向两个TRP传输的PUSCH可以配置独立的传输参数，例如波束和预编码矩阵，但约束向两个TRP传输的PUSCH的传输层数是相同的。终端设备向不同TRP上传输的PUSCH对准相应的TRP进行模拟波束赋形，从而通过空间域区分不同的PUSCH，提供上行的频谱效率。
对于基于码本的PUSCH传输，该单DCI中需要包含两个探测参考信号(Sounding Reference Signal，SRS)资源指示(SRS resource indicator，SRI)域和两个预编码信息和传输层数域，其中，第一个预编码信息和传输层数域用于指示向TRP1发送的PUSCH的预编码信息和传输层数，向TRP2发送的PUSCH的传输层数与第一个预编码信息和传输层数域指示的传输层数相同，第一个SRI域用于指示向TRP1发送的PUSCH的波束方向，第二个SRI域用来指示向TRP2发送的PUSCH的波束方向。其中，网络设备配置2个SRS resource set，通过第一个SRI域和第二个SRI域分别对应2个SRS resource set，用于指示向两个TRP传输的PUSCH的波束方向，第二个预编码信息和层数域只需要指示预编码信息，传输层数默认与第一个预编码信息和层数域指示的传输层数相同。
对于基于非码本的PUSCH传输，该单DCI中需要包含两个SRI域，其中第一个SRI域用于指示向TRP1发送的PUSCH的波束方向和传输层数，第二个SRI域用来指示向TRP2发送的PUSCH的波束方向，向TRP2发送的PUSCH的传输层数与第一个SRI指示的传输层数相同。
在另一些场景中，网络设备也可以通过多个DCI调度终端设备向两个TRP传输PUSCH，该多个DCI可以通过不同的控制资源集(Control Resource Set，CORESET)来承载。网络设备配置多个CORESET组，每个TRP采用各自的CORESET组中的CORESET进行调度，即可以通过CORESET组来区分不同的TRP。例如，网络设备可以为每个CORESET配置一个CORESET组索引，不同的索引对应不同的TRP。
当多TRP的PUSCH的传输方案为TDM方案时，图2示出了一种TDM方案，以基于时隙的TDM重复传输为例，满足以下特征：
重复类型A(基于slot的PUSCH)：在K个连续的时隙的相同符号位置发送两组PUSCH(采用相同或不同的冗余版本(Redundancy Version，RV)版本)，每组PUSCH关联一个SRS资源集合以及传输配置指示(Transmission Configuration Indicator，TCI)状态(state)。
重复类型B(基于mini-slot的PUSCH)：在K次nominal发送机会上发送两组PUSCH(相同或不同的RV版本)，每组PUSCH关联一个SRS资源集合以及TCI state。
为便于理解本申请实施例的技术方案，对本申请相关的上行多天线面板(panel)/TRP传输方案进行说明。
在一些场景中，上行多panel/TRP传输支持的方案包括空分复用(Spatial-division multiplexing，SDM)传输方案、单频网络(Single frequency network，SFN)传输方案和TDM传输方案。
图3是一种SDM传输方案的示意性图，SDM传输方案满足如下特征：
一个PUSCH的不同传输层通过UE的不同panel发送给不同的TRP，不同传输层的所占用的上行资源都相同，不同传输层关联的SRS资源集合不同，TCI state不同。
图4是一种SFN传输方案的示意性图，SFN传输方案满足如下特征：
一个PUSCH的重复传输(例如包括PUSCH1和PUSCH2)通过UE的不同的panel发送到不同的TRP，PUSCH1和PUSCH2所占用的上行资源相同关联的SRS资源集合不同，TCI state不同。
在相关技术中，多panel/TRP的传输方案只能终端设备侧部署的每个panel关联相同的终端设备能力，例如，每个panel关联的SRS resource set所关联的如下配置都是相同的：
SRS resource set中的SRS资源的数量；
网络设备所指示的SRS资源的端口数；
SRS resource set所关联的最大传输层数。
具体地，SRS资源集合中的SRS资源数，SRS资源的端口数，以及每个SRS资源集关联的最大传输层数都是通过无线资源控制(Radio Resource Control，RRC)信令配置的，并且配置为相同的值。
在一些场景中，考虑支持终端设备侧部署的不同panel对应不同的终端设备能力，例如关联的SRS端口数不同。如图5至图7所示，终端设备侧部署3个panel，各panel关联的终端设备能力不同，各个panel关联的SRS端口数不同，分别为1个端口，2个端口和4个端口，此情况下可以认为panel 关联的终端设备能力不对称。此情况下，如何进行传输参数配置(例如在动态切换用于发送上行传输和用于接收下行传输的panel时)以保证传输性能是一项亟需解决的问题。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图8是根据本申请实施例的无线通信的方法200的示意性交互图，如图8所示，该方法200包括如下至少部分内容：
S201，终端设备向网络设备上报终端设备能力；
S202，终端设备接收网络设备指示的n个传输参数集合，其中n为正整数。
在一些实施例中，所述n个上行传输可以是PUSCH传输，或者，也可以是其他上行传输，例如PUCCH传输等，本申请对比不作限定。
在一些实施例中，该n个传输参数集合用于所述终端设备的n个上行传输。
例如，n个传输参数集合中的一个传输参数集合用于该n个上行传输中的一个上行传输，即该n个传输参数集合和该n个上行传输一一对应。
在一些实施例中，所述传输参数集合包括以下参数中的一种或多种的组合：
SRS资源集合索引、SRS资源索引、SRS资源的数量、最大SRS端口数、所述SRS资源集合索引对应的最大传输层数。
在一个具体实施例中，一个传输参数集合包括以下参数：
一个SRS资源集合索引、最大传输层数。
在另一个具体实施例中，一个传输参数集合包括以下参数：
一个SRS资源集合索引、最大传输层数，最大SRS端口数。
在又一个具体实施例中，一个传输参数集合包括以下参数：
一个SRS资源集合索引、最大传输层数、SRS资源索引、SRS资源的数量、最大SRS端口数。
在一些实施例中，该SRS资源集合索引为周期性的SRS资源集合索引，半持续的SRS资源集合索引，非周期的SRS资源集合索引。
在一些实施例中，SRS资源索引用于指示该SRS资源集合索引所指示的SRS资源集合中包括的SRS资源。
在一些实施例中，SRS资源的数量用于指示该SRS资源集合索引所指示的SRS资源集合中包括的SRS资源的数量。
在一些实施例中，最大SRS端口数用于指示该SRS资源集合索引所指示的SRS资源集合中包括的SRS资源对应的最大端口数。
在一些实施例中，n＝1。即该n个上行传输可以是单个上行传输，例如，单TRP/panel的上行传输。
在一些实施例中，n＞1。即该n个上行传输可以是多个上行传输，例如，多TRP/panel的上行传输。该多TRP/panel的上行传输可以是单个DCI调度的，或者，也可以是多个DCI调度的。
也即，本申请实施例可以适用于单TRP/panel的上行传输，或者，也可以适用于多TRP/panel的上行传输，该多TRP/panel的上行传输可以是单DCI调度的，或者，也可以是多DCI调度的，本申请对此不作限定。
在一些实施例中，当n＞1时，该n个传输参数集合中的不同传输参数集合中的传输参数的配置完全相同。此情况可以对应于n个上行传输对应的终端设备能力相同，例如该n个上行传输所使用的panel关联的终端设备能力相同。

在一些实施例中，RRC信令中可以包括所述m个传输参数集合，进一步地，在终端设备上报终端设备能力时，网络设备可以动态指示该m个传输参数集合中的n个传输参数集合，终端设备可以基于该n个传输参数集合发送上行传输。
在另一些实施例中，RRC信令中可以包括所述m个传输参数集合分别对应的索引以及具体的传输参数配置，进一步地，在终端设备上报终端设备能力时，网络设备可以指示激活的或更新的传输参数集合的索引，这样，终端设备可以根据该索引结合从RRC信令获取的该索引对应的传输参数配置确定目标传输参数集合，进一步可以基于该目标传输参数集合发送上行传输。
在一些实施例中，该终端设备的n个上行传输可以包括终端设备待发送的全部上行传输，或者，也可以仅包括待更新传输参数的上行传输，例如终端设备能力发生变化所影响的上行传输。

该实施例1可以适用于单TRP/panel的上行传输、单DCI调度的多TRP/panel的上行传输以及多DCI调度的多TRP/panel的上行传输。
在一些实施例中，在终端设备能力发生变化时，例如终端设备动态切换用于发送上行传输或用于接收下行传输的panel导致终端设备能力发生变化，终端设备可以向网络设备上报更新的终端设备能力，进一步地，网络设备通过MAC CE来更新n个传输参数集合用于终端设备当前的n个上行传输或下行传输，提升了终端设备侧部署不对称能力的panel时进行panel切换的灵活性，并且通过MAC CE动态指示更新的传输参数集合，缩短了切换时延。
在一些实施例中，所述MAC CE可以用于指示以下信息中的一项或多项：

在一些实施例中，在终端设备上报更新的终端设备能力的情况下，网络设备可以根据更新的终端设备能力在m个传输参数集合中选择更新的传输参数集合，进一步通过MAC CE向终端设备指示更新的传输参数集合。例如，网络设备可以根据终端设备上报的更新的SRS端口数选择合适的SRS资源集合索引，例如，选择的SRS资源集合索引指示的SRS资源集合包括的SRS资源的最大SRS端口数大于或等于终端设备上报的SRS端口数。
在一个具体实施例中，网络设备可以通过RRC信令配置大于2个用途‘码本(codebook)’或‘非码本(noncodebook)’的SRS资源集合，分别适配不同的终端设备能力。进一步地，通过MAC CE切换多TRP/panel的上行传输所关联的SRS资源集合(即用于该多TRP/panel的上行传输的SRS资源集合)。网络设备通过MAC CE来指示合适的SRS资源集合，缩短了切换时延，提高终端设备实现的灵活性。
在一些实施例中，该n个传输参数集合可以是通过一个MAC CE指示的，或者，也可以是通过n个MAC CE指示的，例如n个MAC CE中的每个MAC CE用于指示一个传输参数集合。
当n＝1时，例如单TRP/panel的上行传输，网络设备可以通过一个MAC CE指示用于该上行传输的一个传输参数集合。

例如，对于上述场景1，该r个上行传输中的每个上行传输均是单个DCI调度的，则该r个上行传输中的每个上行传输对应的传输参数集合可以通过单独的一个MAC CE指示。其他n-r个上行传输对应的传输参数集合可以通过一个MAC CE指示。
作为一个具体示例，n＝3，p＝2，可以通过一个MAC CE指示两个传输参数集合，通过另一个MAC CE指示一个传输参数集合。
在另一些实施例中，p个MAC CE和n个传输参数集合的对应关系可以是：
p个MAC CE中的每个MAC CE用于指示多个传输参数集合，例如用于指示两个传输参数集合。
例如，对于上述场景2，该s个上行传输对应的传输参数集合可以通过一个MAC CE指示。对于其他n-s个上行传输中的每个上行传输对应的传输参数集合可以通过单独的一个MAC CE指示。

在一些实施例中，对于p个MAC CE中的指示一个传输参数集合的MAC CE可以参考实施例1-1中的MAC CE结构设计，为了简洁，这里不再赘述。
在一些实施例中，对于p个MAC CE中的指示多个传输参数集合的MAC CE可以参考实施例1-2中的MAC CE结构设计，为了简洁，这里不再赘述。
图10是本申请实施例提供的基于实施例1中的传输参数集合的更新方式的示意性交互图。如图10可以包括如下步骤：
S211，网络设备通过RRC信令给终端设备配置多个传输参数集合，该多个传输参数集合对应不同的终端设备能力。例如该多个传输参数集合对应不同的天线端口能力。
S212，终端设备上报终端设备能力。
例如，终端设备初始上报终端设备能力，或者，在终端设备能力发生变化时，上报变化后的终端设备能力，或者说，更新的终端设备能力。
S213，网络设备通过MAC CE指示目标传输参数集合(对应于前文中的n个传输参数集合)。
例如，网络设备可以根据上报的终端设备能力，确定目标传输参数集合。
该目标传输参数集合可以是初始激活的传输参数集合，或者，也可以是更新的传输参数集合。
在一些具体实施例中，对于单TRP/panel的上行传输，网络设备可以通过一个MAC CE指示用于该上行传输的目标传输参数集合。例如，可以采用实施例1-1中所示例的MAC CE结构(例如示例1或示例2)指示目标传输参数集合。
在另一些具体实施例中，对于多DCI调度的多TRP/panel的上行传输，网络设备可以通过多个MAC CE指示用于该多个上行传输中的每个上行传输的目标传输参数集合。例如，可以采用实施例1-1中所示例的MAC CE结构(例如示例3)指示目标传输参数集合，或者，也可以通过实施例1-2中所示例的MAC CE结构指示目标传输参数集合。或者，也可以通过实施例1-3中所述的方式指示目标传输参数集合。
在又一些具体实施例中，对于单DCI调度的多TRP/panel的上行传输，网络设备可以通过一个MAC CE指示用于该多个上行传输中的每个上行传输的目标传输参数集合。例如，可以采用实施例1-2中所示例的MAC CE结构指示目标传输参数集合。或者，也可以通过实施例1-3中所述的方式指示目标传输参数集合。
S214，终端设备根据指示的目标传输参数集合发送上行传输。
因此，在该实施例1中，网络设备通过MAC CE指示目标传输参数集合，能够使得网络设备能够动态的根据终端设备能力激活或更新用于上行传输的传输参数集合，使得激活或更新后的传输参数集合与上报的终端设备能力更加匹配，提升上行传输的可靠性。
实施例2：通过DCI指示传输参数集合。
在一些实施例中，所述n个传输参数集合属于k个传输参数集合，所述k个传输参数集合属于m个传输参数集合，所述m个传输参数集合是通过RRC信令配置的，所述k个传输参数集合是通过MAC CE在所述m个传输参数集合中激活的，其中，m为大于2的正整数，k≤m，n≤k。
例如，网络设备可以通过RRC信令给终端设备配置m个传输参数集合，进一步通过MAC CE指示激活的k个传输参数集合，进一步通过DCI指示该k个传输参数集合中用于上行传输的目标传输参数集合。
在一个具体实施例中，m＝4。
在一个具体实施例中，k＝2。
因此，在本申请实施例中，在动态切换用于发送上行传输或用于接收下行传输的panel的情况下，网络设备通过DCI来更新合适的传输参数集合，缩短了切换时延，提高终端设备实现的灵活性。
在一些实施例中，在终端设备能力发生变化时，例如终端设备动态切换用于发送上行传输或用于接收下行传输的panel导致终端设备能力发生变化，终端设备可以向网络设备上报更新的终端设备能力，进一步地，网络设备可以根据更新的终端设备能力激活k个传输参数集合，进一步通过DCI向终端设备指示该k个传输参数集合中的目标传输参数集合(即所述n个传输参数集合)，用于终端设备当前的n个上行传输或下行传输，提升了终端设备侧部署不对称能力的panel时进行panel切换的灵活性，并且通过DCI动态指示更新的传输参数集合，缩短了切换时延。
在一个具体实施例中，网络设备可以通过RRC信令配置大于2个用途‘码本(codebook)’或‘非码本(noncodebook)’的SRS资源集合，分别适配不同的终端设备能力，然后通过MAC CE激活其中的k个SRS资源集合。进一步地，通过DCI指示待发送的上行传输所关联的SRS资源集合(即用于待发送上行传输的SRS资源集合)。网络设备通过DCI来指示合适的SRS资源集合，缩短了切换时延，提高终端设备实现的灵活性。
在一些实施例中，该n个传输参数集合可以是通过一个DCI指示的。
例如，对于单TRP/panel的上行传输，即n＝1，网络设备可以通过一个DCI指示用于该上行传输的一个传输参数集合。该一个DCI可以是调度该上行传输的DCI。
再例如，对于单DCI调度的多TRP/panel的上行传输，即n＞1，网络设备可以通过一个DCI指示该n个传输参数集合。例如，该一个DCI可以是调度该多个上行传输的DCI。
在另一些实施例中，该n个传输参数集合也可以是通过n个DCI指示的，例如n个DCI中的每个DCI用于指示一个传输参数集合。
例如，对于多DCI调度的多TRP/panel的上行传输，即n＞1，网络设备可以通过n个DCI指示该n个传输参数集合，其中，该n个DCI中的一个DCI用于指示一个传输参数集合。例如一个DCI 可以是用于该DCI调度该上行传输的传输参数集合。
在又一些实施例中，该n个传输参数集合也可以是通过q个DCI指示的，其中，n＞2，q＞1并且q小于n。
在一些实施例中，q个DCI和n个传输参数集合的对应关系可以是：
q个DCI中的s个DCI中的每个s个DCI用于指示一个传输参数集合，其他p-r个DCI中的每个DCI用于指示多个传输参数集合，例如用于指示两个传输参数集合，其中，s为正整数，并且s小于q；或者
q个DCI中的每个DCI用于指示多个传输参数集合，例如用于指示两个传输参数集合，其中，s为正整数，并且s小于q。
作为一个具体示例，n＝3，q＝2，可以通过一个DCI指示两个传输参数集合，通过另一个DCI指示一个传输参数集合。
作为一个具体示例，n＝4，q＝2，可以通过两个DCI指示4个传输参数集合，其中每个DCI用于指示2个传输参数集合。

例如，该多个DCI中包括第一DCI和第二DCI，第一DCI用于调度第一上行传输，第二DCI用于调度第二上行传输，则网络设备可以通过第一DCI指示用于第一上行传输的传输参数集合，通过第二DCI指示用于第二上行传输的传输参数集合。
实施例2-2：第一信息域用于指示多个传输参数集合，该多个传输参数集合中的每个传输参数集合用于一个上行传输。该实施例2-2可以适用于单DCI调度的多TRP/panel的上行传输和多DCI调度的多TRP/panel的上行传输。可选地，该多个传输参数集合和多个TRP/panel一一对应，例如，第一个传输参数集合用于向TRP1发送的上行传输，第二个传输参数集合用于向TRP2发送的上行传输。
在一些实施例中，该第一信息域用于指示n个传输参数集合，该n个传输参数集合中的每个传输参数集合用于n个上行传输中的一个上行传输，其中，n大于1。
例如，对于单DCI调度的多TRP/panel的上行传输，网络设备可以通过一个DCI指示用于多个上行传输中的每个上行传输的传输参数集合，该一个DCI可以是调度该多个上行传输的DCI。对应地，终端设备可以通过该单个DCI获取用于多个上行传输中的每个上行传输的传输参数集合。
又例如，对于多DCI调度的多TRP/panel的上行传输，网络设备可以通过一个DCI指示用于多个上行传输中的每个上行传输的传输参数集合，该一个DCI可以是调度该多个上行传输的多个DCI中的一个。对应地，终端设备可以通过该一个DCI获取用于多个上行传输中的每个上行传输的传输参数集合。

在一些实施例中，第一信息域包括q个比特，共2q个码点，每个码点可以对应MAC CE激活的k个传输参数集合中的一个传输参数集合或两个传输参数集合，其中，q为正整数。
在一些实施例中，MAC CE还用于指示DCI中的第一信息域的每个码点对应MAC CE激活的k个传输参数集合中的传输参数集合的数量n。
例如，MAC CE还包括指示字段，用于指示DCI中的第一信息域的每个码点对应MAC CE激活的k个传输参数集合中的传输参数集合的数量n。
在一个具体实施例中，指示字段可以用于指示第一信息域中的每个码点对应MAC CE激活的k个传输参数集合中的一个还是两个传输参数集合。
以下结合具体实施例，说明该实施例2中的MAC CE的结构设计。
在一些实施例中，MAC CE可以用于指示如下内容：
激活的k个SRS资源集合索引；
每个SRS资源集合索引关联的一组传输参数，例如包括最大传输层数，最大传输层数、SRS资源索引、SRS资源的数量、最大SRS端口数中的一项或多项；
第一信息域的多个码点中的每个码点和SRS资源集合索引(或者说，传输参数集合)的对应关系。
在一个具体实施例中，所述MAC CE用于指示以下信息中的一项或多项：
所述第一信息域的多个码点中的每个码点和SRS资源集合索引的对应关系；
SRS资源集合索引对应的最大传输层数。
作为一个具体示例(记为示例7)，MAC CE包括以下信息：
Serving Cell ID，BWP ID，第一个码点对应的第一SRS资源集合索引，第一SRS资源集合索引对应的最大传输层数，第二个码点对应的第三SRS资源集合索引，第三SRS资源集合索引对应的最大传输层数，……，第2q个码点对应的第2q+1-1SRS资源集合索引，第2q+1-1SRS资源集合索引对应的最大传输层数，预留比特。
在该示例7中，可以认为第一SRS资源集合索引和第一SRS资源集合索引对应的最大传输层数组成一个传输参数集合，第三SRS资源集合索引和第三SRS资源集合索引对应的最大传输层数组成一个传输参数集合，……，第2q+1-1SRS资源集合索引和第2q+1-1SRS资源集合索引对应的最大传输层数组成一个传输参数集合，一个码点对应一个传输参数集合。
在该示例7中，不同码点对应的SRS资源集合索引可以相同，或者，也可以不同。
即，第一SRS资源集合索引，第三SRS资源集合索引，…，第2q+1-1SRS资源集合索引的资源集合索引值可以相同或不同，例如，第一SRS资源集合索引为i的SRS资源集合，第三SRS资源集合索引可以是索引为i的SRS资源集合，也可以是索引为j的SRS资源集合。
作为另一具体示例(记为示例8)，MAC CE包括以下信息：
Serving Cell ID，BWP ID，第一个码点对应的第一SRS资源集合索引，第一SRS资源集合索引对应的最大传输层数，第一个码点对应的第二SRS资源集合索引，第二SRS资源集合索引对应的最大传输层数，第二个码点对应的第三SRS资源集合索引，第三SRS资源集合索引对应的最大传输层数，第二个码点对应的第四SRS资源集合索引，第四SRS资源集合索引对应的最大传输层数，……，第2q个码点对应的第2q+1-1SRS资源集合索引，第2q+1-1SRS资源集合索引对应的最大传输层数，第2q个码点对应的第2q+1SRS资源集合索引，第2q+1SRS资源集合索引对应的最大传输层数，预留比特。
在该示例8中，可以认为第一SRS资源集合索引和第一SRS资源集合索引对应的最大传输层数组成一个传输参数集合，第二SRS资源集合索引和第二SRS资源集合索引对应的最大传输层数组成一个传输参数集合，第三SRS资源集合索引和第三SRS资源集合索引对应的最大传输层数组成一个传输参数集合，……，第2q+1-1SRS资源集合索引和第2q+1-1SRS资源集合索引对应的最大传输层数组成一个传输参数集合，第2q+1SRS资源集合索引和第2q+1SRS资源集合索引对应的最大传输层数组成一个传输参数集合，一个码点对应两个传输参数集合，分别用于不同的上行传输。
在该示例8中，同一码点对应的两个SRS资源集合索引不同。
即，第一SRS资源集合索引和第二SRS资源集合索引不同，第三SRS资源集合索引和第四SRS资源集合索引不同，……，第2q+1-1SRS资源集合索引和第2q+1SRS资源集合索引不同。
在该示例8中，不同码点对应的第一个SRS资源集合索引可以相同，或者，也可以不同，不同码点对应的第二个SRS资源集合索引可以相同，或者，也可以不同。
即，第一SRS资源集合索引，第三SRS资源集合索引，…，第2q+1-1SRS资源集合索引的资源集合索引值可以相同或不同，例如，第一SRS资源集合索引为i的SRS资源集合，第三SRS资源集合索引可以是索引为i的SRS资源集合，也可以是索引为j的SRS资源集合。
第二SRS资源集合索引，第四SRS资源集合索引，…，第2q+1SRS资源集合索引的资源集合索引值可以相同或不同，例如，第二SRS资源集合索引为i的SRS资源集合，第四SRS资源集合索引可以是索引为i的SRS资源集合，也可以是索引为j的SRS资源集合。
可选地，在一些实施例中，所述MAC CE还可以包括指示比特，用于指示第一信息域的每个码点对应MAC CE激活的k个SRS资源集合索引中的一个还是两个传输参数集合。
以q＝2比特为例，第一信息域的码点和传输参数集合的关联关系示例如下：
码点codepoint 00：指示上行传输关联第一组传输参数集合；
码点codepoint 01：指示上行传输关联第二组传输参数集合；
码点codepoint 10：指示上行传输关联第三组传输参数集合；

在一些实施例中，一组传输参数集合中包括的传输参数集合的数量可以由指示字段确定。
例如，在示例7中，一组传输参数集合包括一个传输参数集合，在示例8中，一组传输参数集合包括两个传输参数集合。
在一些实施例中，对于多DCI调度的多TRP/panel的上行传输，例如，多个DCI包括第一DCI和第二DCI，第一DCI和第一CORSET组索引关联，第二DCI与第二CORSET组索引关联，第一DCI用于调度第一上行传输，第二DCI用于调度第二上行传输。
此情况下，传输参数集合的更新方式可以有如下三种：
方式1：第一DCI指示的传输参数集合仅用于第一DCI调度的上行传输，或者说，与第一CORSET组索引关联的第一DCI指示的传输参数集合仅用于与第一CORSET组索引关联的上行传输。
方式2：第一DCI指示的传输参数集合用于所述多个DCI(包括第一DCI和第二DCI)调度的上行传输，或者，与第一CORSET组索引关联的第一DCI指示的传输参数集合用于与第一CORSET组索引关联的上行传输，以及与第二CORSET组索引关联的上行传输。
方式3：第一DCI指示的传输参数集合用于第二DCI调度的上行传输，或者，与第一CORSET组索引关联的第一DCI指示的传输参数集合用于与第二CORSET组索引关联的上行传输。
对于方式1，第一DCI中的第一信息域的一个码点对应一个传输参数集合，例如，对应一个SRS资源集合索引以及关联的一组传输参数，相应地，MAC CE可以采用示例7中的结构。
对于方式2，第一DCI中的第一信息域的一个码点对应多个传输参数集合(例如n个传输参数集合，用于该n个上行传输)，例如，对应2个SRS资源集合索引以及每个SRS资源集合索引关联的一组传输参数，相应地，MAC CE可以采用示例8中的结构。
对于方式3，第一DCI中的第一信息域的一个码点对应一个传输参数集合，例如，对应一个SRS资源集合索引以及关联的一组传输参数，相应地，MAC CE可以采用示例7中的结构。
在本申请一些实施例中，所述方法200还包括：

例如，第一指示信息用于指示第一CORSET组索引关联的DCI指示的传输参数集合用于第一CORESET组索引所关联的上行传输，还是所述第一CORSET组索引以及第二CORSET组索引关联的上行传输，还是第二CORSET组索引关联的上行传输。
在一些实施例中，第一指示信息可以通过RRC信令或MAC CE发送，或者，也可以通过DCI发送。
图11是本申请实施例提供的基于实施例2中的传输参数集合的更新方式的示意性交互图。如图11可以包括如下步骤：
S221，网络设备通过RRC信令给终端设备配置m个传输参数集合，该m个传输参数集合对应不同的终端设备能力，m为大于2的正整数。例如该多个传输参数集合对应不同的天线端口能力。
S222，终端设备上报终端设备能力。
S223，网络设备通过MAC CE指示激活的k个传输参数集合，其中k小于或等于m。
该MAC CE中还可以指示DCI中的第一信息域中的多个码点和传输参数集合的对应关系，例如，可以指示该多个码点中的每个码点分别对应的SRS资源集合索引以及SRS资源集合索引关联的一组传输参数。
S224，网络设备通过DCI指示该k个传输参数集合中的传输参数集合，或者说，用于当前上行传输的目标传输参数集合。
例如，网络设备可以根据设备的终端设备能力，确定目标传输参数集合。
在一些具体实施例中，对于单TRP/panel的上行传输，网络设备可以通过调度该上行传输的DCI指示用于该上行传输的目标传输参数集合，例如通过该DCI中的第一信息域的码点指示用于该上行传输的一个传输参数集合。对应地，终端设备可以根据该DCI的第一信息域的码点确定一个传输参数集合，例如，1个SRS资源集合索引以及关联的传输参数。
在另一些具体实施例中，对于多DCI调度的多TRP/panel的上行传输，网络设备可以通过调度该多个上行传输的多个DCI分别指示其所调度的上行传输的所使用的传输参数集合，例如通过DCI中的第一信息域的码点指示用于该DCI调度的上行传输的一个传输参数集合，此情况下，MAC CE可以采用示例7中的结构设计。或者，也可以通过该多个DCI中中一个DCI指示该多个上行传输分别对应的传输参数集合，此情况下，MAC CE可以采用示例8中的结构设计。
在又一些具体实施例中，对于单DCI调度的多TRP/panel的上行传输，网络设备可以通过该单DCI指示用于该多个上行传输中的每个上行传输的目标传输参数集合，例如通过DCI中的第一信息域的码点指示多个传输参数集合，该多个上行传输用于该DCI调度的多个上行传输，此情况下，MAC CE可以采用示例8中的结构设计。
S225，终端设备根据更新的传输参数集合发送上行传输。
因此，在该实施例2中，网络设备通过DCI指示目标传输参数集合，能够使得网络设备能够动态的根据终端设备能力激活或更新用于上行传输的传输参数集合，使得激活或更新后的传输参数集合与上报的终端设备能力更加匹配，提升上行传输的可靠性。
实施例3：所述n个传输参数集合是通过第一RRC信令配置的。
例如，对于单TRP/panel的上行传输，第一RRC信令中可以包括用于该上行传输的传输参数集合。
又例如，对于多TRP/panel的上行传输，该第一RRC信令中可以包括用于该多个上行传输的传输参数集合。
在一些实施例中，所述方法200还包括：
在接收到所述第一RRC信令到所述第一RRC信令指示的传输参数集合生效之间的第一时长内，所述终端设备根据目标最大传输层数发送上行传输，其中，目标最大传输层数是所述终端设备上报的支持的最大传输层数和第二RRC信令配置的最大传输层数中的较小值，所述第二RRC信令是网络设备上一次配置传输参数集合的RRC信令。
例如，如图12所示，终端设备在t1时刻向网络设备上报更新的终端设备能力，在t2时刻接收到网络设备的第一RRC信令，第一RRC信令中携带更新的传输参数集合，由于RRC信令配置的传输参数生效需要一定的时间，t3时刻传输参数生效，则在t2到t3之间的这一段时间内，基于终端设备当前支持的最大传输层数和网络设备上一次配置的最大传输层数中的较小值进行上行传输，有利于避免终端设备能力和RRC配置不匹配的问题，保证上行传输的可靠性。
综上，在本申请实施例中，终端设备可以向网络设备上报n个上行传输的所支持的终端设备能力时，例如，在用于终端设备的n个上行传输的终端设备能力发生变化时，具体例如终端设备动态切换用于发送上行传输或用于接收下行传输的panel导致终端设备能力发生变化时，终端设备可以向网络设备上报终端设备能力。进一步地，网络设备指示用于该n个上行传输的n个传输参数集合，其中，该n个传输参数集合和该n个上行传输一一对应，即，网络设备可以针对每个上行传输分别配置对应的传输参数集合，一方面提升了终端设备侧部署不对称能力的panel时进行panel切换的灵活性，另一方面通过给每个上行传输分别配置对应的传输参数集合，有利于保证该n个上行传输中的每个上行传输的性能。
