Abstract: A method for wireless communication by a network node includes transmitting, to a group of user equipment (UEs), radio resource control (RRC) signaling to configure a function for enabling and disabling hybrid automatic repeat request (HARQ) feedback for a set of N instances of a multicast transport block (TB). The method also includes transmitting, to the group of UEs, the set of N instances of the multicast TB. The method further includes transmitting, to the group of UEs, a downlink control information (DCI) message on a group-common physical downlink control channel (PDCCH) with a cyclic redundancy check (CRC) scrambled by a group-common radio network temporary identifier (RNTI) configured for the group of UEs. The method also includes receiving, from one or more UEs of the group of UEs, a HARQ feedback message associated with one or more instances of the set of N instances after transmitting all N instances.

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: Aspects of the present disclosure allow for more efficient rate matching by allowing a triggered A-ZP-CSI-RS set to support rate matching around multiple slots. Aspects of the present disclosure may allow a triggered A-ZP CSI-RS set to be applied to less than all scheduled PDSCH slots when DCI schedules PDSCH on multiple slots. Aspects of the present disclosure may extend CSI-RS resource mapping to span multiple adjacent slots. In another instance, aspects of the present disclosure allow a resource mapping configuration to indicate an initial symbol of a plurality of symbols spanning the plurality of slots for a respective A-ZP-CSI-RS resource. Doing so also allows a PDSCH transmission in a slot among the plurality of slots using a rate matching pattern associated with a set of A-ZP-CSI-RE resources to be received. In addition, aspects of the present disclosure can also add periodicity to A-ZP-CSI-RS resource set configuration.

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.
