Abstract: Various technologies pertaining to an impact of more than one PDSCH per slot on a HARQ-ACK CB for multicast are described herein. A UE receives RRC signaling indicating whether more than one PDSCH is configured for at least one slot associated with at least one HARQ-ACK codebook. The UE performs, for the at least one HARQ-ACK codebook for multiplexing feedback between unicast and multicast for HARQ-ACK, one of: an addition of a candidate PDSCH occasion to a set of candidate PDSCH occasions for the at least one slot based on the RRC signaling or TDRA grouping for the at least one slot based on the RRC signaling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a radio resource control (RRC) configuration that indicates that hybrid automatic repeat request (HARQ) feedback associated with a downlink HARQ process is disabled or enabled. The UE may receive a downlink control information (DCI) communication that overrides the RRC configuration. The UE may selectively transmit HARQ feedback, associated with the downlink HARQ process, for a downlink transmission based at least in part on the DCI communication. The UE may selectively initiate, based at least in part on selectively transmitting the HARQ feedback, physical downlink control channel (PDCCH) monitoring associated with the downlink HARQ process based at least in part on at least one of the RRC configuration or the DCI communication. Numerous other aspects are described.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, a first indication to disable hybrid automatic repeat request (HARQ) feedback for a number of instances of a multicast transport block (TB). The method also includes receiving, from the base station, a second indication identifying a value of the number of instances of the multicast TB. The method further includes receiving, from the base station, one or more instances of the multicast TB. The method still further includes determining, based on the one or more received instances, whether the multicast TB is recoverable. The method further includes selectively transmitting, to the base station, HARQ feedback after all instances of the multicast TB have been transmitted by the base station based on the determination of whether the multicast TB is recoverable.

Abstract: A network node may transmit a first signal to a first radio at a user equipment (UE). The UE may receive the first signal from the network node. The first signal may include a first configuration for a second radio at the UE. The UE may operate the second radio in a first mode based on the first configuration received via the first radio. The first radio may have a lower power consumption than the second radio or the second radio may have the lower power consumption than the first radio. For example, one radio may be a low-power wake-up radio (LP-WUR) having a lower power consumption than a main radio (MR) at the UE. The network node and the UE may communicate with one another via the second radio at the UE based on the first configuration transmitted to the first radio.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a group discontinuous reception (DRX) configuration. The UE may receive, based on the group DRX configuration, a notification communication indicative of group handover information associated with a group of UEs that includes the UE. The UE may perform, based on the group handover information, a group handover operation between a source cell and a target cell. 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 base station, a multicast message or a broadcast message that uses a radio link control (RLC) format associated with an RLC acknowledged mode (RLC-AM). The UE may decode the multicast message or the broadcast message to identify information associated with an RLC unacknowledged mode (RLC-UM) based at least in part on a capability of the UE. The UE may operate in accordance with the RLC-UM based at least in part on decoding the multicast message or the broadcast message. Numerous other aspects are provided.

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 suhcarrier 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 withing a resource pool, in the same bandwidth part.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration, for a multicast broadcast service (MBS) single frequency network (SFN) area, indicating configuration information for one or more multicast traffic channels. The UE may receive, in accordance with the configuration, a physical downlink control channel (PDCCH) communication scheduling an MBS SFN data communication associated with a multicast traffic channel, of the one or more multicast traffic channels. The UE may receive the MBS SFN data communication via a physical downlink shared channel (PDSCH) that is associated with both SFN communications and unicast communications or that is associated with only MBS SFN communications. 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, from a base station, an indication that indicates whether a common search space (CSS) is associated with a first type of physical downlink control channel (PDCCH) or a second type of PDCCH. The first type of PDCCH may correspond to a cell-broadcast PDCCH and the second type of PDCCH may correspond to a UE-specific PDCCH. The CSS may be for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE may receive, from the base station, the first type of PDCCH or the second type of PDCCH. Numerous other aspects are described.
