1. A user equipment (UE), comprising:
a transceiver configured to:
receive configuration information for a list of transmission configuration indication (TCI) states associated with a first entity and one or more second entities, wherein:
the first entity is a serving cell, and
each of the one or more second entities is a neighboring cell or a cell with a physical cell identity (PCI) different from a PCI of the serving cell,
receive TCI state code points activated by a medium access control-control element (MAC CE), wherein the MAC CE activates TCI states belonging to different entities, and
receive downlink (DL) control information (DCI) indicating at least one of the activated TCI state code points; and
a processor operably coupled to the transceiver, the processor configured to:
determine a TCI state to apply to at least one of DL channels and uplink (UL) channels within at least one entity, and
update one or more spatial filters for at least one of the DL channels and the UL channels based on the determined TCI state,
wherein the transceiver is further configured to at least one of receive and transmit the DL channels and the UL channels of the at least one entity, respectively, based on the updated one or more spatial filters,
wherein the TCI state includes a source reference signal, and
wherein the source reference signal is identified by a physical cell identity (PCI) index of a cell other than the serving cell and a corresponding synchronization signal/physical broadcast channel (SS/PBCH) block.
