Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a serving cell, an event-based measurement report configuration that indicates a measurement threshold and a beam quantity threshold that is two or more. The UE may determine that a first set of measurements of a first plurality of reference signals satisfy the measurement threshold. Each of the first plurality of reference signals may be associated with a corresponding one of a first plurality of beams. Accordingly, the UE may transmit, to the serving cell, a report based at least in part on the first set of measurements when the first plurality of beams includes a quantity of beams that satisfies the beam quantity threshold. Numerous other aspects are described.

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 detect, using a low-power receiver of the UE, a low-power synchronization signal (LP-SS) that is associated with a first coverage area that is larger than a second coverage area associated with a legacy synchronization signal block. The UE may monitor, using the low-power receiver, for a low-power wake up signal, based at least in part on the LP-SS, that is associated with a third coverage area that is larger than a fourth coverage area associated with a legacy wake up signal. Numerous other aspects are described.

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, 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.
