基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和UE11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。

需要说明的是，多个传输接收节点(Multiple Transmission and Reception Point，Multi-TRP)联合传输技术，利用多传输接收点(Transmission and Reception Point，TRP)传输在增强移动宽带(enhanced Mobile Broadband，eMBB)场景下对长期演进(Long Term Evolution，LTE)，长期演进增强(Long Term Evolution-Advanced，LTE-A)和新无线接入技术(NewRadio Access Technology，NR)中传输吞吐量实现了 有效的提升。NR的另一个技术是多面板(即Multi-Panel)传输，它利用多个天线面板进行传输以获得更高的频谱效率。与此同时，通信系统的传输可靠性也必须要得到保证，利用Multi-TRP或Multi panel的重复发送或接收能够提高接收端获取正确信息的概率，有效地提高在超可靠度和低延迟通讯(Ultra-reliable and Low Latency Communications,URLLC)场景下的传输可靠性。

图2为本公开实施例提供的一种波束指示方法的流程示意图。如图2所示，由用户设备(User Equipment，简称UE)执行，该波束指示方法包括以下步骤：
步骤101，基于波束指示信息，为面向基站多个传输接收点TRP联合传输的目标PUCCH资源确定所使用的目标波束，其中，波束指示信息用于指示至少一个目标波束。
本公开实施例中，可以基于多个物理上行控制信道(Physical Uplink Control Channel，简称PUCCH)资源，确定目标PUCCH资源。可选地，可以根据基站等网络设备发送的控制信令，来确定网络设备为UE指示的面向基站多个传输接收点(Transmission Receive Point，简称TRP)联合传输的目标PUCCH资源。进一步地，可以根据波束指示信息，为目标PUCCH资源从多个候选波束中确定所使用的目标波束。
其中，控制信令，携带有网络设备为UE指示的面向基站多个TRP联合传输的目标PUCCH资源。此种情况下，UE获取该控制信令后，可以基于该控制信令确定出网络设备为UE指示的面向基站多个TRP联合传输的目标PUCCH资源。
在本公开的所有实施例中，该方法还可以应用于多个天线面板panel联合传输的技术方案中。也就是说，步骤101为：基于波束指示信息，为面向基站多个天线面板panel联合传输的目标PUCCH资源确定所使用的目标波束，其中，波束指示信息用于指示至少一个目标波束。
需要说明的是，在本公开的所有实施例中，该方法还可以应用于任何联合传输的技术方案中。
在另一个实施例中，可以根据UE发送的控制信令，来确定为UE指示的支持面向基站多个panel联合传输的目标PUCCH资源。在又一个实施例中，可以根据UE发送的控制信令，来确定为UE指示的支持面向基站联合传输的目标PUCCH资源。
上述控制信令可以是高层信令，也可以是物理层信令，高层信令包括无线资源控制(radio resource control，RRC)信令和/或媒体接入控制(medium access control，MAC)控制单元(control element，CE)MAC-CE信令，物理层信令可以是下行控制信息(Downlink Control Information DCI)。
其中，上述目标PUCCH资源可以是一个或者多个，该实施例对此不作具体限定，在实际应用中，可根据实际需求，指示目标PUCCH资源的数量。
在一些实施例中，在目标PUCCH资源为一个时，为了可以实现多个传输，上述目标PUCCH资源可以对应多个不同波束。例如，上述目标PUCCH资源可以对应两个不同波束。即，在一个实施例中，为了实现多TRP传输，该一个目标PUCCH资源可以对应多个不同波束。为了支持多天线面板联合传输，该一个目标PUCCH资源可以对应多个不同波束。
在另一些实施例中，在目标PUCCH资源为多个时，上述多个目标PUCCH资源可以对应一个波束，或者多个不同波束，该实施例对此不作具体限定。
例如，上述目标PUCCH资源为两个，每个目标PUCCH资源为各自一个波束，或者，每个目标PUCCH资源各自对应两个波束，或者，两个目标PUCCH资源中的一个目标PUCCH资源对应一个波束，而另一个目标PUCCH资源对应两个波束。
根据本公开实施例的一种波束指示方法，用户设备可以通过基于波束指示信息，为面向基站多个传输接收点TRP联合传输的目标PUCCH资源确定所使用的目标波束，其中，波束指示信息用于指示至少一个目标波束，以实现波束指示，使得能够支持面向基站多个传输点TRP或天线面板多个不同的PUCCH资源的联合重复传输，进而通过多个PUCCH资源的联合重复传输，能够带来更好的空间分集增益，更可靠的传输以及更加灵活的配置实现。
需要说明的是，本公开中，可以根据PUCCH资源指示信息PRI，确定目标PUCCH资源，进而确定波束指示信息。
作为一种可能的实现方式，如图3所示，该波束指示方法，具体包括以下步骤：
步骤201，接收基站发送的下行控制信息DCI，其中，DCI中指示并确定至少一个PUCCH资源指示信息PRI。
本公开实施例中，基站可以向UE发送下行控制信令(Downlink Control Information，简称DCI)， 相应地，UE可以接收DCI，并根据DCI，获取指示并确定的PRI。
步骤202，将PRI所指示的PUCCH资源作为目标PUCCH资源。
需要说明的是，每个PRI均能够指示至少一个PUCCH资源，由此，本公开实施例中，在获取到PRI之后，可以将每个PRI所指示的PUCCH资源作为目标PUCCH资源。例如，PRI1所指示的PUCCH为PUCCH1，则PUCCH1可以作为目标PUCCH资源。
步骤203，确定与目标PUCCH资源存在关联关系的波束指示信息。
本公开实施例中，在确定目标PUCCH资源后，可以按照预先设定的规则和联合传输中使用的PUCCH资源之间确定关联关系，并根据关联关系确定与目标PUCCH资源对应的波束指示信息。
其中，对应DCI中的PRI，可以得到对应独立指示的波束指示信息，例如，PRI对应spatialRelationInfo；也可以得到对应联合指示的波束指示信息，例如，针对PRI1和PRI2，确定的波束对应关系为，PRI1对应spatialRelationInfo1，PRI2对应spatialRelationInfo2。
步骤204，基于波束指示信息，为面向基站多个传输接收点TRP的联合传输的目标PUCCH资源确定所使用的目标波束，其中，波束指示信息用于指示至少一个目标波束。
在本公开的所有实施例中，该方法还可以应用于多个天线面板panel联合传输的技术方案中。也就是说，步骤204为：基于波束指示信息，为面向基站多个天线面板panel联合传输的目标PUCCH资源确定所使用的目标波束，其中，波束指示信息用于指示至少一个目标波束。
进一步地，本公开中，UE可以通过多种方式确定波束指示信息。可选地，UE可以接收基站发送的无线资源控制RRC信令；可选地，UE可以接收基站发送的媒体接入控制层控制单元MAC CE信令。
作为一种可能的实现方式，UE可以接收基站发送的无线资源控制RRC信令，其中，RRC信令中配置候选波束集合或候选波束组合的集合，至少一个目标波束属于候选波束集合或候选波束组合的集合。
可选地，可以通过RRC配置PUCCH资源可选的波束集合，其中，波束集合包括多个候选波束，且候选波束相互独立，即言，RRC信令以集合的形式下发。
可选地，可以通过RRC配置可用于PUCCH联合传输的候选波束组合的集合。其中，每一项均可以包括{spatialRelationInfo1，spatialRelationInfo2}的联合指示。
需要说明的是，候选波束至少包括可用于面向基站多个TRP联合传输的波束。可选地，候选波束组合的集合中只包含Multi-TRP对应的候选波束组合；可选地，候选波束组合的集合中可同时包含single-TRP对应的可配置候选波束组合。在另一个实施例中，候选波束至少包括可用于面向基站多个panel联合传输的波束。可选地，候选波束组合的集合中只包含多个panel对应的候选波束组合；可选地，候选波束组合的集合中可同时包含单个panel对应的可配置候选波束组合。需要说明的是，RRC信令也可以以组的形式下发，其中，组内的波束存在关联关系。由此，本公开中，可以基于波束管理(Beam Management)或其他已知信息，通过RRC配置可用于PUCCH联合传输的候选波束组合的集合。
此种情况下，波束指示信息为对应候选波束组合的码点，其中，每个候选波束组合至少包括一个候选波束，此种情况下，可以基于码点，从候选波束组合的集合中确定目标波束组合，其中，目标波束属于目标波束组合。
本公开实施例中，为了可以基于码点，从候选波束组合的集合中确定目标波束组合，可以通过RRC信令进行配置。
可选地，响应于UE中存在码点以及波束组合之间的映射关系，针对每个波束组合，可基于从DCI中得到的码点以及该波束组合，通过查询映射关系，获取与码点匹配的波束组合，以从候选波束组合的集合中确定目标波束组合。
作为另一种可能的实现方式，UE可以接收基站发送的媒体接入控制层控制单元MAC CE信令，其中，MAC CE信令指示波束指示信息用于激活联合传输所使用的目标波束。
可选地，可以通过MAC-CE在可选波束内配置一个或者至多两个用于multi-TRP联合传输的spatialRelationInfo，例如，可以为spatialRelationInfo1，spatialRelationInfo2。该用于联合传输的波束信息独立指示，分别对应MAC-CE激活的适合联合传输的PUCCH资源所在的一个或者两个PUCCH资源集合。可选地，若激活一个或者两个PUCCH资源集合，此种情况下，可以配置两个spatialRelationInfo，对应multi-TRP传输；可选地，若激活一个PUCCH资源集合，此种情况下，可以配置一个spatialRelationInfo，对应single-TRP传输。
进一步地，可以在使用目标波束的目标PUCCH资源上面向基站多个TRP联合重复传输上行控制信息UCI。在另一个实施例中，可以在使用目标波束的目标PUCCH资源上面向基站多个panel联合重复传输上行控制信息UCI。
其中，可以理解的是，不同的PUCCH资源可能对应不同的PUCCH格式。
PUCCH是NR系统中上行链路的一个物理信道，其中承载上行控制信息(Uplink Control Information，UCI)。
为了支持不同UCI比特数范围的传输，NR系统中定义了5中PUCCH帧格式，其中，PUCCH格式下PUCCH的参数示例，如表1所示。
表1 PUCCH格式下PUCCH的参数
PUCCH格式 符号长度 资源块(resource block，RB)个数 承载比特数
0 1–2 1 ≤2
1 4–14 1 ≤2
2 1–2 1,2,..,16整数 >2
3 4–14 1,2,3,4,5,6,8,9,10,12,15,16 >2
4 4–14 1 >2
通过上述表1可以看出，其中，PUCCH格式(PUCCH format)0和1只能承载小于等于2bit的数据，而PUCCH格式2/3/4可承载大于2bit的数据。
可以理解的是，表1中的每一个元素、每一条对应关系，都是独立存在的；这些元素、对应关系被示例性的列在同一张表格中，但是并不代表表格中的所有元素、对应关系必须根据表格1中所示的同时存在。其中每一个元素的值和每一对应关系，是不依赖于表1中任何其他元素值或对应关系。因此本领域内技术人员可以理解，该表1中的每一个元素的取值、每一条对应关系，各种都是一个独立的实施例。
在本申请的一些示例性的实施方式中，上述PUCCH资源包括下列参数：
pucch-ResourceId：PUCCH资源索引
startingPRB(Physical Resource Block，物理资源块)：起始PRB索引
intraSlotFrequencyHopping：时隙间跳频方式
format：配置的PUCCH格式，从format 0到format 4。
在上述目标PUCCH资源为多个的情况下，为了提高传输质量，上述多个目标PUCCH资源之间在时频域完全不重叠。当然，在上述目标PUCCH资源为多个的情况下，上述多个目标PUCCH资源之间在时频域不完全重叠。
在一些实施例中，在为UE指示一个目标PUCCH资源传输UCI，并且采用一个时隙进行重复发送的业务场景中，UE可根据目标PUCCH资源的重复发送次数N，在预设多个时隙(例如一个时隙)内对目标PUCCH资源进行重复发送，以实现对UCI的重传。
例如，目标PUCCH资源为一个，并且重复发送次数为两次的情况下，承载有相同UCI的目标PUCCH资源在一个时隙进行重复发送的示例，如图4所示。
其中，需要说明的是，在本实施例中，上述目标PUCCH资源对应为支持面向基站多个传输接收点TRP联合传输的多个不同波束。
其中，不同波束对应的传输时机的传输次数可以是根据预设规则，对目标PUCCH资源的重复发送次数N进行划分而得到。
在另一些实施例中，在采用一个目标PUCCH资源传输UCI，并且多个时隙间面向基站多个TRP重复发送UCI，UE可根据目标PUCCH资源的重复发送次数N，在多个时隙中重复发送承载有UCI的目标PUCCH资源。在另一些实施例中，在采用一个目标PUCCH资源传输UCI，并且多个时隙间面向基站多个panel重复发送UCI，UE可根据目标PUCCH资源的重复发送次数N，在多个时隙中重复发送承载有UCI的目标PUCCH资源。其中，N为大于1的整数。
可以理解的是，为了提高传输的可靠性，上述多个时隙是依次相邻的，也就是说上述多个时隙是连续的。
在又一些实施例中，在采用多个目标PUCCH资源传输UCI，以及采用多个时隙进行重复发送的场景中，UE可获取每个目标PUCH资源的重复发送次数，并基于每个目标PUCH资源的重复发送次数，在多个时隙内面向基站多个TRP重复发送UCI。在又一些实施例中，在采用多个目标PUCCH资源传输UCI，以及采用多个时隙进行重复发送的场景中，UE可获取每个目标PUCH资源的重复发送次数， 并基于每个目标PUCH资源的重复发送次数，在多个时隙内面向基站多个panel重复发送UCI。
在又一些实施例中，在采用多个目标PUCCH资源传输UCI，以及在一个时隙内进行重复发送的场景中，UE可获取每个目标PUCH资源的重复发送次数，并基于每个目标PUCH资源的重复发送次数，在一个时隙内面向基站多个TRP重复发送UCI。在又一些实施例中，在采用多个目标PUCCH资源传输UCI，以及在一个时隙内进行重复发送的场景中，UE可获取每个目标PUCH资源的重复发送次数，并基于每个目标PUCH资源的重复发送次数，在一个时隙内面向基站多个panel重复发送UCI。
其中，需要说明的是，上述每个目标PUCH资源各自对应的重复发送次数可以是相同的，或者，是均不相同，还可以是部分相同的，该实施例对此不作具体限定。
例如，上述目标PUCCH资源的数量为两个，分别为第一目标PUCCH资源对应的重复发送次数为2次，第二目标PUCC资源对应的重复发送次数为1次，可在一个时隙内，结合第一目标PUCCH资源对应的重复发送次数，使用第一目标PUCCH资源面向基站多个TRP重复发送上行控制信息UCI以及结合第二目标PUCCH资源对应的重复发送次数，使用第二目标PUCCH资源面向基站多个TRP重复发送上行控制信息UCI。其中，上述第一目标PUCCH资源以及第二目标PUCCH资源所承载的DUI是相同的。
其中，重复发送次数N为大于或者等于1的整数，例如，重复发送次数可以为2、4或者8等，该实施例对此不作具体限定。
在一些实施例中，上述重复发送次数可以是通过高层信令为UE配置的。
具体而言，UE可接收UE发送的高层信令，其中，高层信令携带有目标PUCCH资源的重复发送次数。对应地，UE在确定需要传输UCI时，UE根据目标PUCCH资源的重复发送次数，对目标PUCCH资源进行重复发送。
其中，上述是采用时隙内重复发送方式，还是时隙间重复发送方式，在一些实施例中，可以是基于基站发送的指示信令而确定出的，其中，指示信令中包括重复发送方式，重复发送方式为时隙内重复发送方式或者时隙间重复发送方式。在另一些实施例中，还可以是UE基于UE与基站所采用通信协议标准中的重复发送规则而确定出的。
在一些实施例中，上述高层信令可以为RRC信令。在另一些实施例中，上述高层信令为RRC信令和MAC CE信令。
根据本公开实施例的一种波束指示方法，UE可以在使用目标波束的目标PUCCH资源上面向基站多个TRP联合重复传输上行控制信令UCI，由此，利用多TRP或者panel增强上行控制信息的传输和反馈，并通过联合对应不同波束方向的不同PUCCH资源对UCI进行重复发送，可提升上行控制信息的传输质量和可靠性，从而满足了超高可靠超低时延通信业务的通信要求。
图5为本公开实施例提供的另一种波束指示方法的流程示意图。如图5所示，由基站执行，该波束指示方法包括以下步骤：

在本公开的所有实施例中，该方法还可以应用于多个天线面板panel联合传输的技术方案中。也就是说，步骤401为：向UE发送波束指示信息，以指示UE基于所述波束指示信息，为面向基站的多个panel联合传输的目标PUCCH资源确定所使用的目标波束，其中，波束指示信息用于指示至少一个目标波束。
需要说明的是，在本公开的所有实施例中，该方法还可以应用于任何联合传输的技术方案中。
进一步地，本公开中，基站可以通过多种方式向UE发送波束指示信息，可选地，基站可以向UE发送RRC信令；可选地，基站可以向UE发送MAC CE信令。
作为一种可能的实现方式，基站可以向UE发送RRC信令，其中，RRC信令中配置候选波束集合或候选波束组合的集合，至少一个目标波束属于候选波束集合或候选波束组合的集合。相应地，UE可以接收RRC信令；可选地，可以通过RRC配置PUCCH资源可选的波束集合，其中，候选波束至少为 可用于面向基站多个TRP联合传输的波束。可选地，候选波束至少为可用于面向基站多个panel联合传输的波束。其中，波束集合包括多个候选波束，且候选波束相互独立，即言，RRC信令以集合的形式下发；可选地，可以通过RRC配置可用于PUCCH联合传输的候选波束组合的集合。其中，每一项均可以包括{spatialRelationInfo1，spatialRelationInfo2}的联合指示。

本公开实施例中，基站可以向UE发送DCI，其中，DCI中指示并确定至少一个PUCCH资源指示信息PRI。相应地，UE可以接收DCI，并根据DCI确定每个PRI所指示的PUCCH资源作为目标PUCCH资源，然后确定与目标PUCCH资源存在关联关系的波束指示信息，进而基于波束指示信息，为面向基站多个TRP的联合传输的目标PUCCH资源确定所使用的目标波束。
在一些实施例中，基站可以向UE发送DCI，其中，DCI中指示并确定至少一个PUCCH资源指示信息PRI。相应地，UE可以接收DCI，并根据DCI确定每个PRI所指示的PUCCH资源作为目标PUCCH资源，然后确定与目标PUCCH资源存在关联关系的波束指示信息，进而基于波束指示信息，为面向基站多个panel的联合传输的目标PUCCH资源确定所使用的目标波束。
需要说明的是，响应于目标波束为两个及两个以上，此种情况下，可以向UE发送波束指示信息以进行独立指示或者联合指示。
可选地，可以向UE发送用于联合传输的第一波束指示信息；可选地，可以向UE分别发送每个目标波束对应的第二波束指示信息。
需要说明的是，RRC信令也可以以组的形式下发，其中，组内的波束存在关联关系。由此，本公开中，可以基于Beam Management或其他已知信息，通过RRC配置可用于PUCCH联合传输的候选波束组合的集合。
此种情况下，每个候选波束组合至少包括一个候选波束，波束指示信息为对应候选波束组合的码点，码点用于指示UE从候选波束组合的集合中确定目标波束组合，其中，目标波束属于目标波束组合。
进一步地，基站可以接收目标PUCCH资源使用目标波束面向基站多个TRP或pane联合重复传输的UCI。
其中，可以理解的是，不同的PUCCH资源可能对应不同的PUCCH格式。
PUCCH是新无线(New Radio，NR)系统中上行链路的一个物理信道，其中承载UCI。
在目标PUCCH资源为多个的情况下，为了提高传输质量，上述多个目标PUCCH资源之间在时频域完全不重叠。
在一些实施例中，在为UE指示一个目标PUCCH资源传输UCI，并且采用一个时隙进行重复发送的业务场景中，UE可根据目标PUCCH资源的重复发送次数N，在一个时隙内对目标PUCCH资源进行重复发送，以实现对UCI的重传。

在一些实施例中，上述重复发送次数可以是通过高层信令为UE配置的。
具体而言，UE可接收UE发送的高层信令，其中，高层信令携带有目标PUCCH资源的重复发送次数。对应地，UE在确定需要传输UCI时，UE根据目标PUCCH资源的重复发送次数，对目标PUCCH资源进行重复发送。

本公开实施例中，可选地，基站可以响应于采用多TPR联合传输，则指示UE激活至少一个PUCCH资源集，且向UE发送的波束指示信息用于指示至少一个目标波束；可选地，基站可以响应于采用单TPR传输，则指示UE激活一个PUCCH资源集，且向UE发送的波束指示信息用于指示一个目标波束。
在另一实施例中，基站可以响应于采用多plane联合传输，则指示UE激活至少一个PUCCH资源集，且向UE发送的波束指示信息用于指示至少一个目标波束；可选地，基站可以响应于采用单plane传输，则指示UE激活一个PUCCH资源集，且向UE发送的波束指示信息用于指示一个目标波束。
综上所述，本公开提出的波束指示方法，可以支持面向基站多个传输点TRP或天线面板的多个不同的PUCCH资源的联合重复传输方案，进一步地，多个PUCCH资源的联合传输方式可以带来更好的空间分集增益，更可靠的传输及更加灵活的配置实现。
