Abstract: The present disclosure describes methods, system, and devices for receiving multicast and broadcast service (MBS) data by a group of second ends from a first end. One method includes receiving, by a second packet data convergence protocol (PDCP) entity at a second end, the MBS data from a first PDCP entity at the first end. Another method includes receiving, by a second acknowledge mode (AM) point-to-multipoint (PTM) radio link control (RLC) entity at a second end, the MBS data from a first AM PTM RLC entity at the first end. Another method includes receiving, by a second end, a piece of information sent from the first end, wherein the piece of information comprises at least one of the following: a first service identity indicating a MBS service or session in RAN, an indication on whether hybrid automatic repeat request (HARQ) feedback is enabled or disabled.

Abstract: Presented are systems and methods for dynamically changing multicast service delivery between multicast and unicast with service continuity. A wireless communication device may receive multicast radio resource configuration information from a network. The wireless communication device may configure, according to the multicast radio resource configuration information, an air interface protocol stack of the wireless communication device. The wireless communication device may receive data of a multicast service according to the multicast radio resource configuration information.

Abstract: A system and method for managing Multimedia Broadcast Multicast Service (MBMS) continuity. The system and method include transmitting, by a wireless communication device through a first distributed unit (DU) of a wireless communication node to a central unit (CU) of the wireless communication node, a first message. The first DU corresponds to a first subset of a plurality of MBMS services of the CU. The first message indicates a second subset of the plurality of MBMS services that corresponds to a second DU of the wireless communication node. The system and method include receiving, by the wireless communication device from the CU in response to transmitting the first message, a second message including MBMS scheduling information. The system and method include performing, by the wireless communication device, a handover procedure from the first DU to the second DU.
