Association of transmission configuration indicator states to physical cell identities

A method for wireless communication at a base station, comprising:

• identifying an association between a plurality of physical cell identifiers (PCIs) and a plurality of transmission configuration indicator (TCI) states for a user equipment (UE), the plurality of PCIs identifying a plurality of transmission reception points (TRPs);
• transmitting, to the UE, an indication of the identified association;
• and
• transmitting, to the UE based at least in part on transmitting the indication of the identified association, a downlink transmission encoded according to a first PCI or a second PCI based at least in part on the identified association.

An apparatus for wireless communication as a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• receive, using one or more receive beams associated with a transmission configuration indicator (TCI) state, a downlink transmission from a plurality of transmission reception points (TRPs) identified by a plurality of physical cell identifiers (PCIs);
• identify, based at least in part on the TCI state and an association between the plurality of PCIs and a plurality of TCI states, a first PCI of the plurality of PCIs to use to decode the received downlink transmission;
• and
• decode the received downlink transmission using the identified first PCI.
