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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of one of: a quantity of physical uplink control channel (PUCCH) resources in a PUCCH slot for negative acknowledgement (NACK)-only-based multicast feedback, or a quantity of transport blocks (TBs) with the NACK-only-based multicast feedback to be multiplexed in the PUCCH slot. The UE may determine, based at least in part on the indication, the quantity of PUCCH resources in the PUCCH slot for the NACK-only-based multicast feedback. The UE may determine a physical downlink shared channel (PDSCH) processing timeline. The UE may transmit, to the network node, the NACK-only-based multicast feedback using the quantity of PUCCH resources and based at least in part on the PDSCH processing timeline. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication for a reference signal to be transmitted on a first carrier, wherein the UE is configured for reference signal carrier switching between the first carrier and a second carrier associated with uplink data channel or control channel transmission. The UE may receive an indication for uplink transmission switching between the second carrier and a third carrier. The UE may transmit, or suspend transmission, on the third carrier during a time associated with transmission of the reference signal on the first carrier based at least in part on the UE being configured for reference signal carrier switching and uplink transmission switching. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information including a carrier indicator field (CIF) value identifying one or more cells on which the downlink control information is configured to schedule resources. The UE may communicate on the one or more cells based at least in part on a mapping between the CIF value and the one or more cells. Numerous other aspects are described.

Abstract: Certain aspects are directed to a user equipment (UE) configured to receive reference signals from a network node via multiple resource element groups (REGs) including at least one REG carrying a downlink transmission. In some examples, the UE may be configured to receive, from the network node, communication parameters for a downlink transmission, the communication parameters indicative of a first resource element group (REG) bundle and a second REG bundle. In some examples, the UE may receive the downlink transmission via the first REG bundle. In some examples, the UE may be configured to perform channel estimation of the downlink transmission based on reference signals transmitted via the first REG bundle and the second REG bundle.

Abstract: Aspects described herein relate to indicating search spaces and/or control information formats for receiving multicast/broadcast service (MBS) downlink control information (DCI). A device can receive a search space configuration defining one or more search spaces for detecting communications intended for a group of one or more user equipment (UEs), determine a priority for detecting control information transmitted over a control channel based on the one or more search spaces, and perform, based on the priority, detection for the control information over the control channel based on the one or more search spaces and/or the other defined search spaces.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, an uplink grant for a physical uplink shared channel (PUSCH) that is to overlap in time with a physical uplink control channel (PUCCH) used for hybrid automatic repeat request (HARQ) feedback for at least multicast, the uplink grant including a downlink assignment index (UL-DAI) indication that indicates at least one of: whether the HARQ feedback of the PUCCH is to be multiplexed on the PUSCH, or a size for the HARQ feedback. The apparatus may communicate, with the network entity, in accordance with the UL-DAI indication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, configuration information associated with a semi-static hybrid automatic repeat request (HARQ) feedback codebook for multicast messages. The UE may receive, from the network entity, a physical downlink control channel (PDCCH) message, associated with a radio network temporary identifier (RNTI), scheduling one or more multicast physical downlink shared channel (PDSCH) messages. The UE may transmit, to the network entity, one or more fallback HARQ feedback indications, associated with the one or more multicast PDSCH messages, in lieu of transmitting the semi-static HARQ feedback codebook, in accordance with the configuration information and associated with at least one of the RNTI or a feedback configuration associated with the RNTI. Numerous other aspects are provided.
