Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a transmission type for a physical downlink shared channel, wherein the transmission type is a multicast transmission type or a unicast transmission type. The UE may determine, based at least in part on the transmission type for the physical downlink shared channel, a transmission configuration indicator state, of a plurality of possible transmission configuration indicator states, that corresponds to a quasi-co-location assumption, of a plurality of possible quasi-co-location assumptions, for the physical downlink shared channel. The UE may decode the physical downlink shared channel based at least in part on the transmission configuration indicator state. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a broadcast or a multicast (broadcast/multicast) scheduling configuration for a physical downlink control channel (PDCCH), the broadcast/multicast scheduling configuration identifying, for receiving broadcast/multicast communications, at least one of: a plurality of radio network temporary identifiers that are respectively associated with a plurality of beams, or one or more bandwidth parts. The UE may receive a broadcast/multicast communication associated with a broadcast/multicast control channel or a broadcast/multicast traffic channel via a physical downlink shared channel in accordance with the broadcast/multicast scheduling configuration for the PDCCH. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, from a plurality of search space sets associated with a plurality of control resource sets, a subset of the plurality of search space sets to monitor. The UE may monitor the subset of the plurality of search space sets, to receive a downlink control information message, for a physical downlink control channel beam associated with the subset of the plurality of search space sets. Numerous other aspects are provided.
