在多TRP场景中，一个终端设备可能与多个TRP通信。终端设备重复发送PUCCH时，需要分别向多个TRP重复发送PUCCH，因此，现有的单TRP场景中在一个PUCCH资源上重复传输PUCCH的方法无法适用于多TRP场景下的PUCCH重复传输。
基于上述的问题，本申请实施例提供一种可以适用于多TRP场景的PUCCH重复传输方法，由终端设备在多个PUCCH资源上分别重复发送PUCCH，以实现向多个TRP重复发送PUCCH。

另一种示例中，第一无线接入网设备根据预先的配置信息确定终端设备需要向与终端设备通信的多个无线接入网设备中的部分无线接入网设备重复发送PUCCH，在这种情况下，第一无线接入网设备所指示的PUCCH资源的数量可以小于同终端设备通信的无线接入网设备的数量，终端设备使用这些PUCCH资源分别向上述部分无线接入网设备重复发送PUCCH。

本实施例中，由无线接入网设备向终端设备指示至少两个PUCCH资源，终端设备相应地在该至少两个PUCCH资源上向至少两个无线接入网设备重复发送PUCCH，从而可以实现在多TRP场景下终端设备重复发送PUCCH。

可选的，第一无线接入网设备在发送上述指示信息之前，可以首先确定用于终端设备重复传输PUCCH的至少两个PUCCH资源，每个PUCCH资源具有唯一的PUCCH资源索引。第一无线接入网设备再根据PUCCH资源指示与PUCCH资源索引的对应关系，确定该至少两个PUCCH资源对应的目标PUCCH资源指示，并根据该目标PUCCH资源指示，生成上述指示信息。通过上述指示信息指示该目标PUCCH资源指示。
S302、终端设备根据PUCCH资源指示与PUCCH资源索引的对应关系，确定与上述目标PUCCH资源指示对应的上述至少两个PUCCH资源的索引。

示例性的，PUCCH资源的资源标识包括空域信息和符号数，则终端设备可以按照该空域信息和符号数，在该PUCCH资源上重复发送PUCCH。

另外，如上述步骤S303中所述，无线接入网设备可以预先配置每个PUCCH资源所对应的资源标识。
终端设备在接收到上述指示信息后，通过解析指示信息，可以获知至少两个PUCCH资源的索引，进而，终端设备根据PUCCH资源的索引与资源标识的对应关系，可以相应获知PUCCH资源的资源标识。进而，终端设备基于资源标识，在PUCCH资源上重复发送PUCCH。
示例性的，PUCCH资源的资源标识为空域信息，则终端设备可以按照该空域信息，在该PUCCH资源上重复发送PUCCH。

在一个具体示例中，假设资源标识包括空域信息和资源的符号数，假设第一无线 接入网设备指示了三个PUCCH资源，该三个PUCCH资源的资源标识均相同，可以指该三个PUCCH资源的空域信息均相同。而三个PUCCH资源的符号数可以两两不同，也可以部分相同，也可以均相同。
如前文所述，在上述两种可选的实施方式中，一个PUCCH资源的索引可以对应于一个资源标识。这种对应关系可以预先由无线接入网设备配置并发送给终端设备。在一些场景下，无线接入网设备可能并未预先配置PUCCH资源的索引与资源标识的对应关系，或者，终端设备并未获取到PUCCH资源的索引与资源标识的对应关系。本申请实施例中，将这些场景称为PUCCH资源的资源标识未配置的场景。在这些场景下，终端设备可以将预设资源标识作为上述至少两个PUCCH资源的资源标识。
以PUCCH资源的资源标识包括空域信息或TCI状态QCL-TypeD信息为例，若PUCCH资源的资源标识未配置空域信息或TCI状态QCL-TypeD信息，则预设空域信息或TCI状态QCL-TypeD信息可以为包括两个活跃TCI状态的TCI编号或者码点中最小TCI编号或者码点对应的活跃TCI状态。
