Abstract: 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.

Abstract: Provided are a processing method, a network node and a storage medium. The processing method is applied to a first network node and includes determining multicast broadcast service (MBS) control information and sending the MBS control information, where the MBS control information instructs a second network node to process an MBS data packet.

Abstract: 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.

Abstract: The present disclosure describes methods, systems, and devices for enhancing mobility robustness to integrated access and backhaul (IAB) for new radio (NR). One method includes enhancing mobility robustness of a migrating integrated access and backhaul-node (IAB-node) for NR during migration from a source IAB-donor-central unit (CU) to a target IAB-donor-CU by sending, by the source IAB-donor-CU, a handover request message to the target IAB-donor-CU, the handover request message comprising a dual active protocol stack (DAPS) request information. Another method includes enhancing mobility robustness of a migrating IAB-node for NR during migration from a source parent IAB-node to a target parent IAB-node by sending, by an IAB-donor-CU, a F1AP message to the migrating IAB-node, the F1AP message comprising a radio resource control re-configuration (RRCReconfiguration) message comprising a DAPS configuration information.

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.
