摘要： This disclosure describes an architecture for supporting MBS sessions in a wireless access network. Each of such MBS sessions is flexibly and dynamically delivered by the access network into one or more Point-To-Point (PTP, or unicast) and Point-To-Multipoint (PTM, or multicast) delivery instances. As such, a subset of the UEs participating in the MBS may be configured to receive the MBS session in a PTP-like manner and quality. The architecture further allows for access network level switching of one or more of the UEs participating in the MBS session between the PTP mode and PTM mode. Such switching are effectuated dynamically without involvement of application layer. The resource allocations and configuration for the PTP and PTM delivery instances may be performed in the access network collaboratively between a central unit (CU) and one or more distributed units (DUs). Such collaborative resource allocation and configuration may be effectuated using a novel architecture for the signaling messages between the CU and the DUs.

摘要： The present disclosure describes methods, system, and devices for selecting a radio bearer mode for multicast broadcast services (MBS). The method includes informing a radio access network (RAN) that a user equipment (UE) is receiving/interested to receive or no longer receiving/interested to receive multicast broadcast service (MBS) services via a cast mode. The method includes sending, by the UE, MBS interest information to the RAN, the MBS interest information comprising a list of MBS services of interest.

摘要： The present disclosure describes methods, systems, and devices for releasing resources for a recovery integrated access backhaul-node (IAB-node) and/or avoiding, from performing radio resource control (RRC) reestablishment procedure, at least one descendant device of a recovery integrated access backhaul-node (IAB-node) from an initial IAB-donor-central unit (CU) to a new IAB-donor-CU. One method includes sending, by the new IAB-donor-CU to the initial IAB-donor-CU, a user equipment (UE) context release information to indicate the resources to be released; and upon receiving the UE context release information, releasing, by the initial IAB-donor-CU, the resources indicated by the UE context release information. Another method includes sending, by the new IAB-donor-CU to the initial IAB-donor-CU, a message. Another method includes sending, by the initial IAB-donor-CU to the at least one descendant device via the new IAB-donor-CU or new IAB-donor-DU, a radio resource control (RRC) message.

摘要： 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.

摘要： 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.
