配置信令用于配置第一终端在上行信道中进行相同数据的重复传输。配置信令包括传输策略，传输策略用于确定需要切换波束方向的相邻两次重复传输所使用的传输资源。第一终端根据配置信令中的传输策略确定该相邻两次重复传输所使用的第一传输资源和第二传输资源，在第一传输资源和第二传输资源上分别进行上行信道中相同数据的相邻两次重复传输。
传输策略用于指示第一终端如何确定相邻两次重复传输的两个传输资源，以使两个传输资源之间间隔有波束切换时间。

示例性的，第一终端基于上行信道的资源配置确定第一传输资源和第二传输资源。终端确定传输资源的方式包括删除和延迟两种。删除是指：第一传输资源和第二传输资源中的至少一个传输资源是采用删除波束切换时间确定的。延迟是指：第二传输资源是在第一传输资源后延迟波束切换时间确定的。
示例性的，上行信道对同一数据的重复传输包括至少两次重复传输。步骤220中的相邻两次重复传输是指至少两次重复传输中，需要进行波束方向切换的相邻的两次重复传输。

示例性的，第一传输资源对应第一传输时机，第二传输资源对应第二传输时机，第一传输时机结束的符号，与第二传输时机开始的符号之间存在时间间隔，时间间隔大于或等于用于切换波束方向的波束切换时间。

步骤240，终端设备接收网络设备发送的配置信令，配置信令包括上行信道的传输策略。
综上所述，本实施例提供的方法，通过为上行信道的相邻两次重复传输分别配置间隔有波束切换时间的两个传输资源，使两次重复传输分别使用不同的发送波束，向同一基站的不同TRP发送，通过在两个传输资源间间隔波束切换时间，充分考虑终端设备在使用不同波束方向向不同TRP进行上行信道的传输时，需要进行波束切换，为波束切换预留出波束切换时间，便于终端设备实现面向同一基站多个TRP的上行信道的重复传输。
通过在基于多TRP的上行增强PUCCH/PUSCH传输方案中，考虑波束切换时间在传输方案中的引入配置方式，从而支持上行传输可配置的波束切换时间的传输策略，从而优化不同具体传输下的传输效率和可靠性。

例如，第一信令中包括第一传输策略，第二信令中包括第二传输策略。第一终端接收第一信令，根据第一传输策略确定第一传输资源和第二传输资源。第一终端接收第二信令，则用第二传输策略替换第一传输策略，根据第二传输策略确定第一传输资源和第二传输资源。

示例性的，上行信道可以是PUCCH(Physical Uplink Control Channel，物理上行控制信道)或PUSCH(Physical Uplink Shared Channel，物理上行共享信道)。
基于多TRP的上行信道增强方案，主要基于R16(Release 16)的PUCCH/PUSCH重复传输方案。首先介绍R16的上行传输方案，即PUCCH仅支持在时隙间的重复传输，PUSCH支持时隙间的重复传输类型A方式，以及可跨时隙传输的重复传输类型B方式。
一、PUCCH时隙内的重复传输。
在R15(Release 15)/16考虑上行覆盖问题，对PUCCH(对应PUCCH格式1/3/4)引入了在多个时隙(slot)中进行重复传输的机制，不同的PUCCH资源在每个slot的不同传输时机中按照相同的传输符号长度进行传输，如图6所示。一个PUCCH重复传输只能使用一个PUCCH资源，该PUCCH资源配置一个波束(beam)方向spatialRelationInfo(空间关系信息)，并且应用于所有的传输时机上。网络设备通过RRC(Radio Resource Control，无线资源控制)高层信令为PUCCH格式(PUCCH format)配置支持的相应的重复传输次数，指示的重复传输次数的范围定义为{1,2,4,8}，不同的PUCCH资源可能对应不同的PUCCH格式。
二、PUSCH时隙间重复传输。
上行PUSCH时域重复传输增强的两种方式分别是：R16引入的重复类型A传输方式和重复类型B传输方式。
1)PUSCH重复类型A传输方式。
R16的时隙级别的Slot Aggregation(聚合)PUSCH传输适用于某些时延要求很低可靠性要求很高的情况。一个PUSCH在连续的K个时隙中传输，即K个传输时机，从起始时隙中的第S个符号上开始传输，每个传输时机持续L个符号，同时S+L不同超过时隙边界。例如，如图7所示，S等于1，L等于4。第一终端在第一个时隙的第1个符号至第4个符号进行第1次重复传输，在第二个时隙的第1个符号至第4个符号进行第2次重复传输。
2)PUSCH重复类型B传输方式。
为了降低时延提高可靠性，R16支持以Mini-slot(迷你时隙，也可以称为“子时隙”)为单位的PUSCH重复传输方案，且允许PUSCH传输跨时隙可以进一步降低时延。在时域上，一个PUSCH在起始时隙中的第S个符号上开始传输，连续发送K个传输时机(nominal repetition)，每个传输时机都连续(back-to-back)占用L个符号，传输S+L可以跨时隙边界。
如图8所示，当S等于1，L等于4，第一终端被配置为进行2次上行信道的重复传输。第一终端在第一个时隙的第1个符号至第4个符号进行第1次重复传输，在第一个时隙的第5个符号至第8个符号进行第2次重复传输。
在传输时机出现跨时隙边界的情况下，传输会被重新分割。
如图9所示，当S等于1，L等于4，第一终端被配置为进行4次上行信道的重复传输。 第一终端在第一个时隙的第1个符号至第4个符号进行第1次重复传输，在第一个时隙的第5个符号至第8个符号进行第2次重复传输。由于根据配置信息，第3次重复传输的4个符号跨过了时隙的时隙边界，则将第3次重复传输分割为两次重复传输，在第一个时隙的第9个符号至第10个符号进行第3次重复传输，在第二个时隙的第1个符号至第2个符号进行第4次重复传输。在第二个时隙的第3个符号至第7个符号进行第5次重复传输。即，第一终端实际进行了5次重复传输，每次重复传输发送相同的数据。
如图10所示，当S等于1，L等于14，第一终端被配置为进行1次上行信道的重复传输。由于一个时隙的长度为10个符号，每个传输时机却要占用14个符号，则第1次重复传输的14个符号会跨过时隙边界，将第1次重复传输分割为两次重复传输，在第一个时隙的第1个符号至第10个符号进行第1次重复传输，在第二个时隙的第1个符号至第4个符号进行第2次重复传输。即，第一终端实际进行了2次重复传输，每次重复传输发送相同的数据。
对于整个传输来讲，时隙L*K表示PUSCH传输的时域资源窗口长度，DL(Downlink，下行信道)符号被丢弃不用于PUSCH的传输。基站可以配置SFI(Short Elementary File Identifier，短基本文件标识符)半静态Flexible(可变的)符号为动态UL(Uplink，上行信道)符号或动态DL符号，因此半静态Flexible符号对PUSCH可能是可用符号，也可能是不可用符号。其中，当存在不可用符号时，第一终端需要丢弃不可用符号，之后在剩余的可用符号上传输。基站还可以通过信令配置UE(User Equipment，用户设备)不可使用的无效符号图样，即在信令指示的无效符号上，UE不传输上行数据。
在R16的标准化中，主要定义了下行PDSCH采用的基于多点协作传输的增强传输方案，基站多TRP/PANEL(面板)的应用利用多个TRP或面板之间的协作，从多个角度的多个波束进行信道的传输/接收，可以更好的克服各种遮挡/阻挡效应，保障链路连接的鲁棒性，适合URLLC(Ultra Reliable Low Latency Communication，超可靠低延迟通信)业务提升传输质量和满足可靠性要求。R17需要继续利用多TRP技术增强上行传输，其中包括上行控制信道PUCCH和上行数据信道PUSCH。在R17multi-TRP(多TRP)增强中，PUCCH/PUSCH支持在以上定义的传输方式下在不同的传输时机(TO,Transmission Occasion)上向不同的TRP方向上协作发送同一传输块(Transport Block，TB),以进一步应用空间复用传输提高传输可靠性。
对于PUCCH信道传输，R17增强的可能方案为：
一、PUCCH时隙间(inter-slot)的重复传输。
同R15/R16的TDM(Time Division Multiplexing，时分复用)重复传输方式，实现在面向多个TRP的多个波束方向上在多个时隙上分时协作发送。
二、PUCCH时隙内(intra-slot)的重复传输。
即面向多个TRP的多个波束方向上在一个时隙内分时联合传输。
1)基于时隙内sub-slot(子时隙)的传输方案：
即在时隙内以sub-slot为单位进行PUCCH的重复发送。例如，如图11所示，在时隙内进行两次上行信道的重复传输，在时隙内相同频域的两个物理资源块上，分别使用第1波束301、第2波束302向不同TRP发送相同数据。
2)基于时隙内跳频发送为基础的传输方案：
即在一个PUCCH资源内，时隙内前后两跳(hop)对应的不同符号组(或称“物力资源块”)上分别对应不同的beam发送。例如，如图12所示，在时隙内进行两次上行信道的重复传输，在时隙内不同频域的两个物理资源块上，分别使用第1波束301、第2波束302向 不同TRP发送相同数据。
其中，第一终端面向不同TRP发送的PUCCH/PUSCH的波束发送方向和不同的传输时机之间的映射关系有多种映射方案可以考虑，下面举例3种典型方案：
方案a：周期映射。两个波束方向依次循环映射到配置的多个传输时机上，例如，进行4次重复传输时，波束方向映射的图样可以是#1#2#1#2，其中，#1对应第一波束方向，#2对应第二波束方向。
方案b：连续映射。两个波束方向连续循环映射到配置的多个传输时机上，例如，进行4次重复传输时，波束方向映射的图样可以是#1#1#2#2；对于4次以上的重复传输，则重复该图样，如对于8次重复传输，则波束方向映射的图样可以是#1#1#2#2#1#1#2#2。
方案c：对半映射。两个波束方向连续映射到配置的多个传输时机上，例如，进行8次重复传输时，波束方向映射的图样可以是#1#1#1#1#2#2#2#2。
传输策略包括删除波束切换时间的策略、延迟波束切换时间的策略中一种。
示例性的，删除波束切换时间的策略是指：第一传输资源和第二传输资源中的至少一个传输资源是采用删除波束切换时间确定的。延迟波束切换时间的策略是指：第二传输资源是在第一传输资源后延迟波束切换时间确定的。
删除可以理解为从网络设备为两次重复传输配置的名义传输时机中删除波束切换时间后，确定两个传输资源。延迟可以理解为将在后一次重复传输对应的名义传输时机延迟波束切换时间之后，得到实际传输时机。
结合上述PUCCH在时隙内的重复传输方式，以及PUSCH的重复类型B传输方式，可以至少得到以下十二种传输策略：

上述十二种传输策略的排序不分先后。
示例性的，基于不同的应用场景，网络设备可以为第一终端配置不同的传输策略。
例如，响应于PUCCH中用于进行一次重复传输的子时隙的符号数小于阈值，网络设备向第一终端发送第一配置信令，第一配置信令包括上行信道的传输策略，该传输策略为延迟波束切换时间的策略。当子时隙内的符号数较少时，采用延迟发送的策略可以保证上行数据传输的可靠性。
再如，响应于PUCCH中用于进行一次重复传输的子时隙的符号数大于阈值，网络设备向第一终端发送第二配置信令，第二配置信令包括上行信道的传输策略，该传输策略为删除波束切换时间的策略。当子时隙内的符号数较多时，采用删除发送的策略可以降低上行传输的时延。
再如，响应于PUSCH中时延要求高于阈值，网络设备向第一终端发送第二配置信令，第二配置信令包括上行信道的传输策略，该传输策略为删除波束切换时间的策略。当上行传输对时延要求较高时，采用删除发送的策略可以降低上行传输的时延。
再如，响应于PUSCH中时延要求低于阈值，网络设备向第一终端发送第一配置信令，第一配置信令包括上行信道的传输策略，该传输策略为延迟波束切换时间的策略。当上行传输对时延要求较低时，采用延迟发送的策略可以提高上行数据传输的可靠性。
示例性的，网络设备还可以基于其他场景或需求，为第一终端配置不同的传输策略。例如，基于对传输的具体方式、时隙资源分配情况、业务的时延要求、信道性能要求、波束映射方式等多种场景，网络设备可以对应地配置适合的传输策略进行上行信道的重复传输。
