1. A non-transitory computer readable storage medium comprising a set of instructions, wherein the set of instructions when executed by a processor cause the processor of a user equipment (UE) to perform operations, comprising:
receiving a physical downlink control channel (PDCCH) transmission configured with downlink control information (DCI) in a single-DCI, multi-transmission/reception point (TRP) operation, wherein the DCI is received on a first serving cell and schedules reception of a physical downlink shared channel (PDSCH) transmission on a second serving cell;
determining whether or not a TCI field is configured in the DCI;
when the TCI field is not configured in the DCI, determining a default beam based on a control resource set (CORESET) with the lowest ID in the PDCCH;
when the TCI field is configured in the DCI, determining whether the TCI field indicates a TCI codepoint includes two TCI states; and
determining a default beam on which the UE receives the PDSCH.
