具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
在5G/NR Rel-16中，主要针对PDSCH传输引入了与多TRP相关的操作，与多TRP相关的操作可以包括单DCI操作和多DCI操作。利用单个DCI，单个PDCCH可用于调度来自多个TRP的多个PDSCH传输。
图1示出了根据本公开实施例的用于下行链路传输的示例性基于单DCI的多TRP相关操作。作为示例，提供两个TRP(TRP#A和TRP#B)以与具有多个天线面板的UE进行通信。如图1所示，对于单DCI操作，来自TRP#A的携带单个DCI的单个PDCCH可以调度从TRP#A到UE的PDSCH传输(PDSCH#1)和从TRP#B到UE的PDSCH传输(PDSCH#2)两者。
如上所述，与多TRP相关的操作可以包括单DCI操作和多DCI操作。另一方面，与多TRP相关的操作可以包括用于下行链路(例如PDSCH)的与多TRP相关的操作和用于上行链路(例如PUSCH)的与多TRP相关的操作。在5G/NR Rel-16中，主要针对PDSCH传输引入了与多TRP相关的操作，但是未定义用于PUSCH传输的与多TRP相关的操作。
在R18中，上行同时传输可能支持的传输方案为对于多天线面板Panel/接收和发送点TRP/传输配置指示TCI的上行同步传输，基于单个DCI(S-DCI)的PUSCH传输的一个传输块(Transport Block，TB)的协作传输，包括多种不同的传输方案，下面对每种传输方案进行简单说明：
一种方案是空分复用(Space Division Multiplexing，SDM)方案：PUSCH的一个TB通过不同panel上分配的各自对应的解调参考信号(Demodulation Reference Signal，DMRS)端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的Panel/TRP/传输时机(Transmission Occasion，TO)分别和不同的TCI state相关联，即与不同的波束相关联。在此基础上，SDM方案又具体分为SDM-A和SDM-B两种方案，其中，在SDM-A方案中，PUSCH的一个TB的不同部分分别通过不同Panel上分配的各自对应的DMRS端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的Panel/TRP/TO分别和不同的TCI状态相关联；在SDM-B方案中，PUSCH的对应不同RV版本的同一个TB的重复通过不同Panel上分配的各自对应的DMRS端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的Panel/TRP/TO分别和不同的TCI状态相关联。
另一种方案是频分复用(Frequency Division Multiplexing，FDM)方案：PUSCH的一个TB通过不同Panel上分配的相同DMRS端口或端口组合分别面向两个不同的TRP在相同时域资源上的不重叠频域资源上进行发送，不同的Panel/TRP/TO分别和不同的TCI状态相关联。在此基础上，FDM方案又具体分为FDM-A和FDM-B两种方案，其中，在FDM-A方案中，PUSCH的一个TB的不同部分分别通过不同Panel上分配的相同DMRS端口或端口组合分别面向两个不同的TRP在相同时域资源上的不重叠频域资源上进行发送，不同的Panel/TRP/TO分别和不同的TCI状态相关联；在FDM-B方案中， PUSCH的对应不同RV版本的同一个TB的重复通过不同Panel上分配的相同DMRS端口或端口组合分别面向两个不同的TRP在相同时域资源上的不重叠频域资源上进行发送，不同的Panel/TRP/TO分别和不同的TCI状态相关联。
又一种方案是空间复用SFN方案：PUSCH的一个TB通过不同Panel上分配的相同DMRS端口或端口组合分别面向两个不同的TRP在相同的时频资源上进行发送，不同的Panel/TRP/TO分别和不同的TCI状态相关联。
基于多panel的上行PUSCH同时传输通常会支持上述方案中的一种或多种。
在基于单个PDCCH调度多天线面板/多TRP传输时，为了使得多点协作传输更加有用，实现在单TRP和多TRP传输之间的切换是极为重要的。
在本申请中，提供了一种技术方案，能够实现在单TRP和多TRP之间的切换以使得多点协作传输更加有效，从而能够有效提高数据传输的可靠性和吞吐率。
下面结合附图对本申请所提供的预编码指示方法及装置进行详细地介绍。
图2示出了根据本公开实施例的一种预编码指示方法的流程示意图。如图2所示，该方法可由网络设备执行，且可以包括以下步骤。
S201，向UE发送单个DCI，该单个DCI中包括TCI波束指示信息和传输配置信息，其中，TCI波束指示信息用于指示UE进行传输所使用的波束信息，当TCI波束指示信息指示一个波束时，传输配置信息包括用于单天线面板单TRP传输的一组信息指示域，以及当TCI波束指示信息指示两个或更多个波束时，传输配置信息包括用于多天线面板多TRP传输的两组或更多组信息指示域。每组信息指示域包括SRI指示域以及TPMI指示域中的至少一个。
在本实施例中，在DCI中除了包括TCI波束指示信息以及传输配置信息，其中根据TCI波束指示信息指示一个波束还是指示两个或更多个波束，传输配置信息可以动态地包括一组信息指示域或包括两组或更多组信息指示域。当传输配置信息包括一组信息指示域时，该DCI可以用于单天线面板单TRP传输，而传输配置信息包括两组或更多组信息指示域，该DCI可以用于多天线面板多TRP传输。其中，每组信息指示域可以为SRI指示域和TPMI指示域中的至少一个，但本申请并不限于此，每组信息指示于还可以包括除SRI指示域和TPMI指示域的其他信息指示域。
在一些实施例中，单个DCI中的TCI波束指示信息指示一个波束且传输配置信息可以包括一个TPMI指示域，其中该TPMI指示域用于指示该波束方向上的PUSCH传输的预编码矩阵，则该单个DCI用于单天线面板单TRP传输，且该单天线面板单TRP传输为基于码本的PUSCH传输。
在一些实施例中，单个DCI中的TCI波束指示信息指示两个或更多个波束且传输配置信息可以包括两个或更多个TPMI指示域，其中每个TPMI指示域用于指示相应的波束方向上的PUSCH传输的预编码矩阵，则该单个DCI用于多天线面板多TRP传输，且该多天线面板多TRP传输为基于码本的PUSCH传输。针对每个波束方向上的PUSCH传输，由一个TPMI指示域指示在该PUSCH传输所使用的预编码矩阵。
在一些实施例中，单个DCI中的TCI波束指示信息指示一个波束且传输配置信息可以包括一个SRI指示域，其中该SRI指示域用于指示该波束方向上的PUSCH传输所被分配的SRS资源集合中的一个或多个携带预编码信息的SRS资源，则该单个DCI用于单天线面板单TRP传输，且该单天线面板单TRP传输为基于非码本的PUSCH传输。
在一些实施例中，单个DCI中的TCI波束指示信息指示两个或更多个波束且传输配置信息可以包括两个或更多个SRI指示域，其中每个SRI指示域用于相应的波束方向上的PUSCH传输所被分配的SRS资源集合中的一个或多个携带预编码信息的SRS资源，则该单个DCI用于多天线面板多TRP传输，且该多天线面板多TRP传输为基于非码本的PUSCH传输。针对每个波束方向上的PUSCH传输，由一个SRI指示域指示从该PUSCH传输所被分配的SRS资源集合中选择的一个或多个SRS资源。对于基于码本的PUSCH传输中，通过SRI指示为PUSCH传输选择相应的空间滤波器(Spatial Filter)，即PUSCH使用SRI选择的SRS资源对应的空间关系信息(TCI或Spatial Relation Info)作为发送使用的空间滤波。对于基于非码本的PUSCH传输中，通过一个SRS资源集合中的多个单端口SRS资源携带了终端计算并建议使用的PUSCH预编码信息，每个SRS资源携带对应一层数据使用的预编码信息，基站通过测量对于终端上报的预编码信息进行调度选择并通过SRI指示对预编码信息进行选择，即在对应的SRS资源集合中选择一个或多个SRS资源，终端在接收到基站的SRI指示后，就使用一个或多个对应的SRS资源对应的预编码作为PUSCH发送使用的预编码。

S401，获取秩指示信息，其中秩指示信息用于指示UE在每个波束方向上的PUSCH传输使用的TRI。
在一些实施例中，秩指示信息根据以下中任一项获取：单个DCI的解调参考信号(Demodulation Reference Signal，DMRS)域；单个DCI的任一指示域的保留码点或扩展码点；单个DCI的新增指示域以及单个DCI支持的码字数。
DCI的DMRS域中可以指示对应每个波束方向上的PUSCH传输使用的DMRS端口信息，例如，对于指示的DMRS端口为{0,1}且对应的传输方案为FDM或SFN传输，则对应每个波束方向的PUSCH传输的DMRS端口都使用端口{0,1}，即TRI为2。例如，对应指示的DMRS端口为{0，1}且对应的传输方案为SDM传输时，则也可以根据预定义的规则分别确定在每个TCI波束方向上PUSCH传输对应的DMRS端口，可能的端口分配是，第一个波束方向上的PUSCH传输使用DMRS端口为{0}，且对应的TRI为1，第二个波束方形上的PUSCH传输使用DMRS端口{1}，且对应的TRI为1。

其中，TPMI子表从码本预配置表中根据相应的波束方向上的PUSCH传输使用的TRI确定，码本预配置表根据相应的波束方向上的PUSCH传输的码本参数配置以及相应的波束方向上的PUSCH传输的码本子集限制确定。每个TPMI指示域占用的比特数根据码本预配置表中与每个可用TRI对应的可用TPMI组合数量的最大值N1 max确定，其中每个可用TRI根据相应的波束方向上的PUSCH传输的码本参数配置以及相应的波束方向上的PUSCH传输的码本子集限制确定。
在本实施例中，网络设备向UE发送的单个DCI中携带的TCI波束指示信息指示两个或更多个波束以及传输配置信息包括两个或更多个TPMI指示域，则该单个DCI用于多天线面板多TRP传输，且该多天线面板多TRP传输为基于码本的PUSCH传输。每个波束方向上的基于码本的PUSCH传输对应一个TPMI指示域，即一个TPMI指示域可以指示在一个波束方向上的基于码本的PUSCH传输的预编码矩阵。网络设备能够确定每个波束方向上的PUSCH传输的码本参数配置以及码本子集限制，由此可以确定用于每个波束方向上的PUSCH传输的码本预配置表，此外网络设备能够获取每个波束方向上的PUSCH传输使用TRI，由此可以从确定的码本预配置表中确定TPMI子表，网络设备向UE发送的DCI 中携带的传输配置信息中包括的每个TPMI指示域可以携带索引，该索引用于根据TPMI子表指示TPMI。TPMI指示域占用的比特数根据相应的码本预配置表中与每个可用TRI对应的可用TPMI组合数量中的最大值确定。
码本参数配置可以对天线端口数、是否使用变换预编码以及maxRank进行配置，而码本子集限制包括三种，分别为：全部、部分和非相关；部分和非相关；非相关。
在一个示例中，对于关联一个天线面板/TRP/PUSCH传输时机/TCI波束方向的PUSCH传输，当网络设备确定该波束方向上的PUSCH传输的码本参数配置为：4个天线端口、不使用变换预编码、maxRank＝2或3或4(for 4 antenna ports,if transform precoder is disabled,maxRank＝2 or 3 or 4)，以及该波束方向上的PUSCH传输的码本子集限制为部分和非相关时，网络设备可以确定该波束方向上的PUSCH传输的码本预配置表为上表1中的由黑体字对应的表格。此外，网络设备获取到该波束方向上的PUSCH传输使用的TRI的值，则网络设备可以确定相应的TPMI子表为该表格中TRI为该值的子集，例如，若获取到TRI＝3，则网络设备可以确定相应的TPMI子表为该表格中TRI＝3(3layers)的子集，该TPMI子表中的索引重新排序，即如表3所示；又如，若获取到TRI＝2，则网络设备可以确定相应的TPMI子表为该表格中TRI＝2(2layers)的子集，该TPMI子表中的索引重新排序，即如表4所示。用于指示该波束方向上的PUSCH传输的预编码矩阵的TPMI指示域可以根据该TPMI子表来指示TPMI，例如，在根据TRI＝3确定的表3中，若TPMI指示域携带索引1，则指示TPMI＝1，若TPMI指示域携带索引2，则指示TPMI＝2。
在所确定的码本预配置表中，可用TRI为1、2、3、4。当TRI＝1时，可用TPMI组合数量为12个，当TRI＝2时，可用TPMI组合数量为14个，当TRI＝3时，可用TPMI组合数量为3个，当TRI＝4时，可用TPMI组合数量为3个，则TPMI指示域所占用的比特数可以确定为

在另一个示例中，对于一个波束方向上的PUSCH传输，当网络设备确定该波束方向上的PUSCH传输所支持的上行最大传输层数为3(L max＝3)，以及该波束方向上的PUSCH传输的所被分配的SRS资源集合中的SRS资源数量为4(N SRS＝4)时，网络设备可以确定该波束方向上的PUSCH传输的SRI预配置表为上表7中的由黑体字对应的表格。此外，网络设备获取到该波束方向上的PUSCH传输使用的TRI的值，则网络设备可以确定相应的SRI子表为该表格中TRI为该值的子集，例如，若获取到TRI＝3，则网络设备可以确定相应的SRI子表为该表格中TRI＝3(3个SRI)的子集，该SRI子表中的索引重新排序，即如表10所示；又如，若获取到TRI＝2，则网络设备可以确定相应的SRI子表为该表格中TRI＝2(2个SRI)的子集，该SRI子表中的索引重新排序，即如表11所示。用于指示该波束方向上的PUSCH传输的SRS资源的SRI指示域可以根据该SRI子表来指示SRI，例如，在根据TRI＝2确定的表11中，若SRI指示域携带索引1，则指示SRI＝0,2，若SRI指示域携带索引2，则指示SRI＝1,2。
在所确定的SRI预配置表中，可用TRI为大于等于1小于等于L max与N SRS中的较小者(在此示例中，min{L max,N SRS}＝3)，即1、2、3。当TRI＝1时，可用SRI组合数量为3个，当TRI＝2时，可用SRI组合数量为6个，当TRI＝3时，可用SRI组合数量为4个，则SRI指示域所占用的比特数可以确定为

对于TRI＝2，其中6个码点分别表示相应的码本预配置表中的TRI＝2的SRI取值，而剩余的2位为保留位，如上表11所示。

UE能够确定每个波束方向上的PUSCH传输所支持的上行最大传输层数以及每个波束方向上的PUSCH传输所被分配的SRS资源集合中的SRS资源数量，由此可以确定用于每个波束方向上的PUSCH传输的SRI预配置表。UE在接收到该单个DCI后，根据该单个DCI中携带的传输配置信息包括的每个SRI指示域中指示的SRI和TRI、以及SRI预配置表来确定用于每个波束方向上的PUSCH传输的SRS资源。
例如，UE接收到网络设备发送的DCI中携带的TCI波束指示信息指示两个波束，即第一波束方向和第二波束方向，且传输配置信息包括两个SRI指示域，即第一SRI指示域和第二SRI指示域，其中第一SRI指示域携带索引6以及第二SRI指示域指示索引1。当UE确定该第一波束方向上的PUSCH传输所支持的上行最大传输层数为4(L max＝4)，以及该第一波束方向上的PUSCH传输的所被分配的SRS资源集合中的SRS资源数量为3(N SRS＝3)，以及UE确定该第二波束方向上的PUSCH传输所支持的上行最大传输层数为3(L max＝3)，以及该第二波束方向上的PUSCH传输的所被分配的SRS资源集合中的SRS资源数量为4(N SRS＝4)时，则UE确定用于第一波束方向上的PUSCH传输的SRI预配置表为上表6中的由黑体字对应的表格，而用于第二波束方向上的PUSCH传输的码本预配置表为上表7中的由黑体字对应的表格。然后，UE可以根据第一SRI指示域携带索引6以及用于第一波束方向上的PUSCH传输的SRI预配置表，确定该第一波束方向上的PUSCH传输的SRS资源为TRI＝3，SRI＝0,1,2指示的SRS资源，并根据第二SRI指示域携带索引1以及用于第二波束方向上的PUSCH传输的SRI预配置表，确定该第二波束方向上的PUSCH传输的SRS资源为TRI＝1，SRI＝1指示的SRS资源。
S1003，在每个波束方向上使用相应的SRS资源携带的预编码信息进行基于非码本的PUSCH传输。
UE在确定用于每个波束方向上的PUSCH传输的SRS资源之后，UE在每个波束方向上使用所确定的SRS资源携带的预编码信息进行基于非码本的PUSCH传输。
在一些实施例中，SRI指示域与SRS资源集合中的关联关系可以是预定义的或通过单个DCI中的SRS资源集合指示域来指示。
假设网络设备发送的单个DCI中携带的TCI波束指示信息指示三个波束(分别对应第一波束方向、第二波束方向以及第三波束方向)，该单个DCI中携带的传输配置信息包括三个SRI指示域(分别为第一SRI指示域、第二SRI指示域以及第三SRI指示域)，在一个示例中，网络设备和UE可以预定义该第一SRI指示域指示从第一波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源，即第一SRI指示域指示用于第一波束方向上的PUSCH传输的SRS资源，该第二SRI指示域指示从第二波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源，而该第三SRI指示域指示从第三波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源；在另一示例中，网络设备可以通过该单个DCI中的SRS资源集合指示域来进行指示，例如，在该单个DCI中新增SRS资源集合指示域，该SRS资源集合指示域指示该第一SRI指示域指示从第一波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源，该第二SRI指示域指示从第二波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源，而该第三SRI指示域指示从第三波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源。
根据本公开实施例的预编码指示方法，网络设备向UE发送承载TCI波束指示信息和传输配置信息的单个DCI，UE根据该单个DCI进行PUSCH传输，其中TCI波束指示信息用于指示UE进行传输所使用的波束信息，TCI波束指示信息指示两个或更多个波束且传输配置信息包括两个或更多个SRI指示域，其中每个SRI指示域既指示SRI又指示TRI。由此，该单个DCI中可用基于码本的多天线面板多TRP传输，从而使得多点协作传输更加有效，由此有效地提高数据传输的可靠性和吞吐率。
图11示出了根据本公开实施例的一种预编码指示方法的流程示意图。如图11所示，该方法可由网络设备执行，且可以包括以下步骤。
S1101，接收网络设备发送的单个DCI，该单个DCI中包括TCI波束指示信息和传输配置信息，其中，TCI波束指示信息用于指示UE进行传输所使用的波束信息，TCI波束指示信息指示两个或更多个波束，以及传输配置信息包括用于多天线面板多TRP传输的两个或更多个SRI指示域，并且每个SRI指示域根据SRI子表表指示SRI。
其中，SRI子表从码本预配置表中根据相应的波束方向上的PUSCH传输使用的TRI确定，SRI预配置表根据相应的波束方向上的PUSCH传输所支持的上行最大传输层数以及相应的波束方向上的PUSCH传输所被分配的SRS资源集合中的SRS资源数量确定。每个SRI指示域占用的比特数根据SRI预配置表中与每个可用TRI对应的可用SRI组合数量的最大值N2 max确定，其中每个可用TRI根据相应的波束方向上的PUSCH传输所支持的上行最大传输层数以及相应的波束方向上的PUSCH传输所被分配的SRS资源集合中的SRS资源数量中的较小者确定。
在本实施例中，网络设备向UE发送的单个DCI中携带的TCI波束指示信息指示两个或更多个波束以及传输配置信息包括两个或更多个SRI指示域，则该单个DCI用于多天线面板多TRP传输，且该多天线面板多TRP传输为基于非码本的PUSCH传输。每个波束方向上的基于非码本的PUSCH传输对应一个SRI指示域，即一个SRI指示域可以指示在一个波束方向上的基于非码本的PUSCH传输的SRS资源。网络设备能够确定每个波束方向上的PUSCH传输所支持的上行最大传输层数以及每个波束方向上的PUSCH传输所被分配的SRS资源集合中的SRS资源数量，由此可以确定用于每个波束方向上的PUSCH传输的SRI预配置表，此外网络设备能够获取每个波束方向上的PUSCH传输使用TRI，由此可以从确定的SRI预配置表中确定SRI子表，网络设备向UE发送的DCI中携带的传输配置信息中包括的每个SRI指示域可以携带索引，该索引用于根据SRI子表指示SRI。SRI指示域占用的比特数根据相应的SRI预配置表中与每个可用TRI对应的可用SRI组合数量中的最大值确定。
例如，对于一个波束方向上的PUSCH传输，当网络设备确定该波束方向上的PUSCH传输所支持的上行最大传输层数为4(L max＝4)，以及该波束方向上的PUSCH传输的所被分配的SRS资源集合中的SRS资源数量为4(N SRS＝4)时，网络设备可以确定该波束方向上的PUSCH传输的SRI预配置表为表6中的由黑体字对应的表格。此外，网络设备获取到该波束方向上的PUSCH传输使用的TRI的值，则网络设备可以确定相应的SRI子表为该表格中TRI为该值的子集，例如，若获取到TRI＝3，则网络设备可以确定相应的SRI子表为该表格中TRI＝3(3个SRI)的子集，该SRI子表中的索引重新排序，即如表8所示；又如，若获取到TRI＝2，则网络设备可以确定相应的SRI子表为该表格中TRI＝2(2个SRI)的子集，该SRI子表中的索引重新排序，即如表9所示。用于指示该波束方向上的PUSCH传输 的SRS资源的SRI指示域可以根据该SRI子表来指示SRI，例如，在根据TRI＝3确定的表8中，若SRI指示域携带索引1，则指示SRI＝0,1,3，若SRI指示域携带索引2，则指示SRI＝0,2,3。
在所确定的SRI预配置表中，可用TRI为大于等于1小于等于L max与N SRS中的较小者(在此示例中，L max＝N SRS＝4)，即1、2、3、4。当TRI＝1时，可用SRI组合数量为4个，当TRI＝2时，可用SRI组合数量为6个，当TRI＝3时，可用SRI组合数量为4个，当TRI＝4时，可用SRI组合数量为1个，则SRI指示域所占用的比特数可以确定为

表示向上取整。
如上所示，虽然根据TRI＝3确定出的SRI子表中的可用SRI组合仅包括0,1,2；0,1,3；0,2,3；1,2,3四种，但该SRI子表的码点数为相应的码本预配置表中的所有可用TRI对应的可用SRI组合数量中的最大值确定，即由TRI＝2对应的可用SRI组合数量6确定，由此，该SRI子表的码点位数为8位。
在一些实施例中，对于特定TRI，SRI子表中的码点数为2^M2，其中K2个码点分别表示相应的SRI预配置表中的与特定TRI对应的K2个SRI取值，剩余(2^M2-K2)个码点为保留值，其中M2为

例如，参考以上示例，对于TRI＝3，其中4个码点分别表示相应的码本预配置表中TRI＝3的SRI取值，而剩余4位为保留位，如上表8所示。
对于TRI＝2，其中6个码点分别表示相应的码本预配置表中的TRI＝2的SRI取值，而剩余的2位为保留位，如上表9所示。
S1102，根据两个或更多个SRI指示域中的每个SRI指示域中所指示的SRI、以及SRI子表，确定用于每个波束方向上的PUSCH传输的SRS资源。
UE能够确定每个波束方向上的PUSCH传输所支持的上行最大传输层数以及每个波束方向上的PUSCH传输所被分配的SRS资源集合中的SRS资源数量，由此可以确定用于每个波束方向上的PUSCH传输的SRI预配置表，此外可以根据每个波束方向上的PUSCH传输使用的TRI可以从SRI预配置表中确定用于每个波束方向上的PUSCH传输的SRI子表。UE在接收到该单个DCI后，根据该单个DCI中携带的传输配置信息包括的每个SRI指示域中指示的SRI、以及SRI子表来确定用于每个波束方向上的PUSCH传输的SRS资源。
例如，UE接收到网络设备发送的DCI中携带的TCI波束指示信息指示两个波束，即第一波束方向和第二波束方向，且传输配置信息包括两个SRI指示域，即第一SRI指示域和第二SRI指示域，其中第一SRI指示域携带索引2以及第二SRI指示域指示索引5。当UE确定该第一波束方向上的PUSCH传输所支持的上行最大传输层数为4(L max＝4)，以及该第一波束方向上的PUSCH传输的所被分配的SRS资源集合中的SRS资源数量为3(N SRS＝3)，以及UE确定该第二波束方向上的PUSCH传输所支持的上行最大传输层数为3(L max＝3)，以及该第二波束方向上的PUSCH传输的所被分配的SRS资源集合中的SRS资源数量为4(N SRS＝4)时，则UE确定用于第一波束方向上的PUSCH传输的SRI预配置表为上表6中的由黑体字对应的表格，而用于第二波束方向上的PUSCH传输的码本预配置表为上表7中的由黑体字对应的表格。然后，UE可以根据第一波束方向上的PUSCH传输使用的TRI＝2可以从相应的码本预配置表中确定用于第一波束方向上的PUSCH传输的SRI子表为上表9，并根据第二波束方向上的PUSCH传输使用的TRI＝2可以从相应的码本预配置表中确定用于第二波束方向上的PUSCH传输的SRI子表为上表11。然后，UE可以根据第一SRI指示域携带索引2以及用于第一波束方向上的PUSCH传输的SRI预配置表，确定该第一波束方向上的PUSCH传输的SRS资源为SRI＝1,2指示的SRS资源，并根据第二SRI指示域携带索引5以及用于第二波束方向上的PUSCH传输的SRI预配置表，确定该第二波束方向上的PUSCH传输的SRS资源为SRI＝2,3指示的SRS资源。
S1103，在每个波束方向上使用相应的SRS资源携带的预编码信息进行基于非码本的PUSCH传输。
UE在确定用于每个波束方向上的PUSCH传输的SRS资源之后，UE在每个波束方向上使用所确定的SRS资源携带的预编码信息进行基于非码本的PUSCH传输。
在一些实施例中，SRI指示域与SRS资源集合中的关联关系可以是预定义的或通过单个DCI中的SRS资源集合指示域来指示。
假设网络设备发送的单个DCI中携带的TCI波束指示信息指示三个波束(分别对应第一波束方向、第二波束方向以及第三波束方向)，该单个DCI中携带的传输配置信息包括三个SRI指示域(分别为第一SRI指示域、第二SRI指示域以及第三SRI指示域)，在一个示例中，网络设备和UE可以预定义该第一SRI指示域指示从第一波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源，即第一SRI指示域指示用于第一波束方向上的PUSCH传输的SRS资源，该第二SRI指示域指示从第二波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源，而该第三SRI指示域指示从 第三波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源；在另一示例中，网络设备可以通过该单个DCI中的SRS资源集合指示域来进行指示，例如，在该单个DCI中新增SRS资源集合指示域，该SRS资源集合指示域指示该第一SRI指示域指示从第一波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源，该第二SRI指示域指示从第二波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源，而该第三SRI指示域指示从第三波束方向上的PUSCH传输所被分配的SRS资源集合中选择SRS资源。
根据本公开实施例的预编码指示方法，网络设备获取UE的每个波束方向上的PUSCH传输使用的TRI，并向UE发送承载TCI波束指示信息和传输配置信息的单个DCI，UE根据该单个DCI进行PUSCH传输，其中TCI波束指示信息用于指示UE进行传输所使用的波束信息，TCI波束指示信息指示两个或更多个波束且传输配置信息包括两个或更多个SRI指示域，其中每个SRI指示域仅指示SRI。由此，该单个DCI中可用基于码本的多天线面板多TRP传输，从而使得多点协作传输更加有效，由此有效地提高数据传输的可靠性和吞吐率。
