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: A receiving device re-establishing a packet data convergence protocol (PDCP) entity. The receiving device resets a robust header compression (ROHC) context. The receiving device receives packet retransmissions having header compression based on the ROHC. The receiving device performs decompression of the packet retransmissions. The receiving device discards duplicate packets after performing the decompression of the packet retransmissions.

Abstract: Wireless communications systems and methods related to acknowledgement/negative-acknowledgement (ACK/NACK) feedback operations for multicast communications are provided. A first user equipment (UE) receives, from a base station (BS), a multicast feedback configuration indicating a first resource configuration for a negative-acknowledgement (NACK) feedback mode; and a second resource configuration for an acknowledgement/negative-acknowledgement (ACK/NACK) feedback mode. The first UE receives, from the BS, a first multicast communication. The first UE transmits, to the BS, a NACK feedback for the first multicast communication based on the first resource configuration. The first UE receives, from the BS, a second multicast communication. The first UE transmits, to the BS, an ACK feedback or a NACK feedback for the second multicast communication based on the second resource configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more repetitions of a broadcast message for broadcast service in one or more transmission occasions. The UE may determine a hybrid automatic repeat request (HARQ) configuration that indicates whether HARQ combining is supported for the broadcast message based at least in part on one or more properties of the broadcast message. The UE may perform a decode attempt on a transport block carried in the one or more repetitions of the broadcast message based at least in part on the HARQ configuration. 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 a configuration that indicates a duration of a dormancy timer for switching from an active bandwidth part to a dormant bandwidth part configured for the UE; start or restart the dormancy timer based at least in part on a determination that a condition is satisfied; and switch to the dormant bandwidth part based at least in part on a determination that the dormancy timer has expired. 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, 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a neighbor cell list that indicates at least one neighbor cell. The UE may perform a cell selection procedure or a cell reselection procedure to switch to a serving cell without receiving an updated neighbor cell list from the serving cell. Numerous other aspects are provided.

Abstract: This disclosure relates to techniques for providing access control for multicast or broadcast (MC/BC) services. A base station broadcasts one or more cell barring parameters to a group of user equipment (UEs) that indicate whether the UEs of the group of UEs is permitted to select the cell of the base station for receiving the MC/BC services. The base station also broadcasts one or more access control parameters to a set of one or more UEs, of the group of UEs, that are indicated to be permitted to select the cell for receiving the MC/BC services based on the one or more cell barring parameters. The one or more access control parameters indicate whether the set of one or more UEs is permitted to establish or resume the RRC connected state with the base station for receiving the MC/BC services.

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 or broadcast radio bearer (MRB) in a radio link control (RLC) acknowledged mode (AM). The UE may determine an adjustment of an RLC AM transmission window of a base station. The RLC AM transmission window may be associated with retransmission of RLC packets associated with the MRB. The UE may synchronize an RLC AM reception window of the UE with the RLC AM transmission window based at least in part on determining the adjustment of the RLC AM transmission window of the base station. The RLC AM reception window may be associated with reassembly of RLC packets associated with the MRB. 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 a configuration for a shared physical downlink shared channel (PDSCH). The UE may receive a first communication via the shared PDSCH and a first bearer based at least in part on the configuration, the first communication being one of a unicast communication or a multicast/broadcast communication. The UE may receive a second communication via the shared PDSCH and the first bearer or a second bearer based at least in part on the configuration, the second communication being the other of the unicast communication or the multicast/broadcast communication. Numerous other aspects are provided.
