Mechanism and Signalling on Coreset and PUCCH Resource Grouping for Multi-TRP Operation

Abstract:

Systems, devices, and techniques for physical uplink control channel (PUCCH) resource grouping in wireless communication systems that include transmission and reception points (TRPs) are described. A described technique performed by a user equipment (UE) includes receiving a PUCCH resource group configuration associated with TRPs, including a first TRP and a second TRP; and performing PUCCH transmissions to the TRPs in accordance with the PUCCH resource group configuration. The PUCCH resource group configuration can include a configuration for a first group of PUCCH resources associated with the first TRP and a second group of PUCCH resources associated with the second TRP.
