Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive signaling indicating a set of multicast configurations for a set of multicast modes supported by the UE. Each multicast mode of the set of multicast modes may be associated with one or more radio resource control (RRC) states. The UE may determine a multicast configuration of the set of multicast configurations based on an RRC state according to which the UE is operating. The UE may receive, while operating according to the RRC state, multicast data according to the determined multicast configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a configured set of control channel elements (CCEs) for physical downlink control channel (PDCCH) decoding for a scheduled cell of a set of scheduled cells, wherein the configured set of CCEs is on a per scheduled cell basis or a per carrier indicator field value basis. The UE may decode downlink control information (DCI) in one or more CCEs of the monitored configured set of CCEs. Numerous other aspects are described.

Abstract: A base station multicasts a physical downlink shared channel (PDSCH) transmission and transmits downlink control associated with the PDSCH, wherein the downlink control comprises different parameters for uplink transmissions to multiple user equipments (UEs). A UE receives the associated the PDSCH, where the downlink control comprises different parameters for uplink transmissions to multiple UEs including an uplink transmission parameter for the UE. The UE receives the multicast PDSCH and transmits the uplink transmission based on the uplink transmission parameter for the UE and the multicast PDSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration for monitoring one or more physical downlink control channels (PDCCHs) for downlink control information (DCI) that schedules physical downlink shared channel (PDSCH) communications on each carrier included in a set of carriers and for DCI that schedules physical uplink shared channel (PUSCH) communications on one or more carriers. The UE may monitor the one or more PDCCHs for DCI in accordance with the configuration. The UE may receive DCI that schedules a PUSCH communication on the one or more carriers based at least in part on the monitoring. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARM) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: A wireless communication device can flexibly change subcarrier spacing (SCS) and/or cyclic prefix (CP) in wireless communication. The wireless communication device can transmit, in a first sidelink resource of a sidelink resource pool, a first sidelink transmission using a first configuration of subcarrier spacing (SCS) and cyclic prefix (CP). The wireless communication device can further transmit, in a second sidelink resource of the sidelink resource pool, a second sidelink transmission using a second configuration of SCS and CP, the second configuration being different from the first configuration in terms of at least one of an SCS or a CP. The techniques allow more efficient switching between SCS and CP configurations within a resource pool in the same bandwidth part.
