Apparatuses and methods for transmission modes configuration in a wireless communication system. A method for operating a user equipment (UE) includes receiving a configuration for one or more of a plurality of physical uplink control channel (PUCCH) resources that are associated with one or more of a plurality of entity identities (IDs), respectively, and receiving information for associating the one or more PUCCH resources with the one or more entity IDs, respectively. The method further includes determining, based on the configuration and the information, a PUCCH resource for a target entity ID, from the plurality of entity IDs and transmitting the PUCCH resource for the target entity ID. The target entity ID corresponds to at least one of: a physical cell ID (PCI), a CORESETPoolIndex value, a PCI index pointing to a PCI, a reference signal (RS) resource ID, a RS resource set ID, and a RS resource setting ID.
