1. A method for wireless communications performed by a user equipment (UE), comprising:
receiving a single medium access control (MAC) control element (CE) that activates a plurality of physical downlink shared channel (PDSCH) transmission configuration indicator (TCI) state identifiers (IDs);
receiving a single downlink control information (DCI) scheduling a PDSCH transmission for a frequency resource in a first set of frequency resources, wherein the DCI comprises a single TCI code point value;
determining, based on the TCI code point value, at least two activated PDSCH TCI state IDs of the plurality of activated PDSCH TCI state IDs, wherein:
a first activated PDSCH TCI state ID of the at least two activated PDSCH TCI state IDs is associated with the first set of frequency resources, and
a second activated PDSCH TCI state ID of the at least two activated PDSCH TCI state IDs is associated with a second set of frequency resources, different from the first set of frequency resources; and
processing the PDSCH transmission according to the first activated PDSCH TCI state ID.
