Abstract: Systems and methods for multicast data traffic service continuity under multicast-broadcast services (MBS) operation during a radio resource control (RRC) state or mode transition are described. In some embodiments, a user equipment (UE) receives, from a network, while in an RRC connected mode, an RRC release message comprising an RRC inactive mode point to multipoint (PTM) configuration that uses an MBS session to receive multicast data traffic while the UE is in an RRC inactive mode; enters the RRC inactive mode from the RRC connected mode in response to the RRC release message; and uses the RRC inactive mode PTM configuration to receive, from the network, the multicast data traffic of the MBS session while the UE is in the RRC inactive mode. Cases where a UE instead re-uses an RRC connected mode PTM configuration after transitioning to the RRC inactive mode are also described. Analogous network behaviors are described.
