Quasi co-location related priority rules for multi-downlink control information based multi-transmission/reception point
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a particular control resource set (CORESET), downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The UE may be configured with multi-DCI based multi-transmission/reception point (TRP) operation. The UE may determine, based at least in part on the UE being configured with multi-DCI based multi-TRP operation, a fixed higher layer index that identifies a CORESET group with which the particular CORESET is associated. The UE may perform an operation, associated with receiving the PDSCH or transmitting the PUSCH, based at least in part on the fixed higher layer index identifying the CORESET group with which the particular CORESET is associated. Numerous other aspects are provided.
