Abstract: In some implementations, a first network node may receive, from a second network node, a first multicast/broadcast service (MBS) data activity message that indicates that no downlink data is available for transmission in an active MBS session. The first network node may transmit, to a third network node and based at least in part on receiving the first MBS data activity message, a multicast/broadcast radio bearer (MRB) context suspension indication that indicates that an MRB context associated with the active MBS session is to be suspended.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing measurements and other functions in preparation for communicating with a base station on a secondary cell (SCell). In particular, a user equipment (UE) may switch to a certain bandwidth part (BWP) (e.g., a dormant BWP) on an SCell when the SCell is deactivated, and the UE may perform the appropriate measurements and functions on this BWP (e.g., based on reference signals received on this BWP). In some cases, the UE may determine to switch to the BWP for performing the appropriate measurements and functions based on an inactivity timer expiring or based on an indication from a base station (e.g., on a primary cell (PCell)). Accordingly, once the UE activates the SCell for communications with a base station, the latency associated with preparing for communicating on the SCell may be reduced.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a radio resource control (RRC) release message that indicates a first point-to-multipoint (PTM) configuration for a multicast service provided by a serving cell of the UE. The first PTM configuration may identify a first set of resources to monitor for the multicast service while the UE is in an RRC inactive state. The RRC release message may further indicate whether a second PTM configuration is present for the serving cell of the UE, whether the second PTM configuration is different from the first PTM configuration, or both. The UE may monitor the serving cell for the multicast service in accordance with the first PTM configuration or the second PTM configuration based on transitioning from an RRC connected state to the RRC inactive state in accordance with the RRC release message.
