Abstract: Methods and apparatuses are described herein for remote UE mobility management. Methods are proposed to consider the impact of coverage through PC5 interface when a remote UE is doing the cell (re)selection. A remote UE may select a serving cell considering the impact of coverage through PC5 interface when the remote UE and the Relay UE are in coverage of different cells. The remote UE may detect and reselect a cell via the Uu interface while it has selected a serving cell via a Relay UE. The remote UE may detect and reselect to a cell via a Relay UE while it has selected a serving cell via the Uu interface.

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.
