Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical uplink control channel (PUCCH) resource set configuration including a first subset of PUCCH resources and a second subset of PUCCH resources, wherein PUCCH resources in the first subset of PUCCH resources are configured with a parameter per PUCCH resource, and wherein PUCCH resources in the second subset of PUCCH resources do not include a parameter per PUCCH resource. The UE may identify a parameter to be used for transmitting a PUCCH communication based at least in part on the PUCCH resource set configuration. The UE may transmit one or more repetitions of the PUCCH communication based at least in part on the parameter. Numerous other aspects are described.
