    Abstract: Wireless User Equipment, UE, and network apparatuses may be adapted to facilitate continuity of Multicast/Broadcast Service, MBS, across cells. A UE in idle/inactive mode, for example, may receive MBS assistance information comprising scheduling information defining MB S reception windows and perform a cell re selection evaluation process accordingly. An UE in connected mode may conduct and report MB S quality measurements and receive an RRC reconfiguration comprising an MB S configuration for a target cell, determine that MBS transmission progress differs between the source cell and the target cell, and recover lost MBS PDUs or delete duplicate MBS PDUs accordingly. A network apparatus, such as a gNB for example, may map a GPRS Tunneling Protocol Sequence Number of an MBS PDU, to a Packet Data Convergence Protocol Sequence Number in a target cell, and determine an MB S configuration for use by a UE requesting a handover accordingly.

    Abstract: A Sidelink AS group management function is disclosed for a UE to discover group members and organize them into AS layer sub-groups based on the AS layer group context information. A centralized Sidelink AS group management is disclosed that the Sidelink AS Group Manager discovers group members and organizes them into AS layer sub-groups for a UE. A Subgroup formation and configuration procedure is disclosed that SL AS Group Manager organizes the ULG into AS layer sub-groups, configures UE-to-UE relays for each UE in the ULG and sends the AS group management information to the UE. A distributed Sidelink AS group management method is disclosed that each UE discovers its group members and organizes the ULG into AS layer sub-groups. New Layer 2 structures and procedures are disclosed to enhance bearer management for Sidelink groupcast communications.

    Abstract: The present application at least describes a method for obtaining channel access in a network. The method includes a step of selecting, via a gNodeB, a spatial filter from a first set of spatial filters to perform listen before talk (LBT). The method includes a step of detecting, via the gNodeB, a channel in an idle state. The method also includes a step of obtaining, a directional channel occupancy time (COT) in the channel in a direction of the selected spatial filter. The method also includes a step of transmitting, to a node, a channel access indicator transmission (CAI-T) on a beam in the cot via a spatial filter of a second set of spatial filters. The method further includes a step of receiving, from the node, a channel access indicator response (CAI-R). The method further includes a step of sensing, via short channel sensing and via the spatial filter or another spatial filter of the second set of spatial filters, the channel is clear. The method even further includes a step of sending, via the channel, information to the node using one or more spatial filters of the second set of spatial filters. Other embodiments of this aspect include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.
