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 a notification of a change to multicast broadcast (MB) control information associated with at least one MB service to which the UE is subscribed, the MB control information being included in an MB control channel (MBCCH) scheduled by a physical downlink control channel (PDCCH) communication addressed to an MB radio network temporary identifier (MB-RNTI); and monitor one or more resources of the MBCCH to receive updated MB control information based at least in part on receiving the notification of the change to the MB control information. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may establish a network interface link with a centralized unit (CU). The network node may establish a set of one or more network interface links with a set of one or more distributed units (DUs). The network node may receive a first communication intended for a destination node via the network interface link. The network node may transmit the first communication to a first DU of the set of one or more DUs via a first network interface link of the set of one or more network interface links. The network node may receive a second communication intended for the destination node via the network interface link. The network node may transmit, after transmitting the first communication via the first network interface link, the second communication to a second DU via a second network interface link.

Abstract: Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) proxy may establish communication links with a RAN and a first AMF of a first network operator, and with a second AMF of a second network operator. The AMF proxy may receive a first message from the RAN, the first AMF, or the second AMF, the message indicating a manipulated or unmanipulated AMF user equipment (UE) identifier (ID) and a manipulated or unmanipulated RAN UE ID. The AMF proxy may perform ID manipulation the UE IDs in the first message based on a first mapping between the manipulated and unmanipulated AMF UE ID and a second mapping between the manipulated and unmanipulated RAN UE ID. The AMF proxy may transmit a second message to the first AMF, the second AMF, or the RAN based on the AMF UE ID or the RAN UE ID.

Abstract: Certain aspects of the present disclosure provide techniques for slice-aware network selection. Particular aspects provide for a method for wireless communication performed by a user equipment (UE). The method generally includes obtaining, for one or more networks, network slicing information indicating one or more slice identifiers supported in the one or more networks, deriving a list of one or more preferred networks based, at least in part, on the network slicing information, and selecting a network to register with from the list of one or more preferred networks.

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: 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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive synchronization signal block (SSB) related measurement configurations exclusively in a system information block (SIB). The UE may receive SSB frequency lists for idle measurements in both a SIB or a radio resource control (RRC) message, such as an RRC release message. In some examples, the UE may receive SSB related measurement configurations or SSB frequency lists for idle measurements in a SIB and an RRC message. Additionally or alternatively, the UE may receive SSB frequency lists in a SIB and an RRC message, while SSB measurement configurations for SSB frequencies out of a sync raster may exclusively be indicated in the RRC message. The UE may therefore experience improved coverage and reliability and, in some examples, may promote low latency for wireless communications relating to multiple radio access technologies, among other benefits.
