Abstract: Presented are systems and methods for traffic transmission in an integrated access and backhaul (IAB) network. A first network node can send a first message to a second network node. The first message can include information to manage the migration of traffic between a first topology managed by the first network node and a second topology managed by the second network node. A first network node can send a first message to an IAB-node. The first message can include information for re-routing of traffic.

Abstract: Techniques relating to a multicast broadcast service are described. In one example aspect, the method includes receiving, by a first network node, from a second network node, a third information, and transmitting, by the first network node, a fourth information associated with one or more multicast broadcast service (MBS) sessions.

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, 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: Provided are an initiation method and apparatus, a reselection method and apparatus, a device, and a storage medium. The initiation method is applied to a first communication node, where the first communication node is in a connected state, an idle state or an inactive state, and includes: receiving relay function configuration information sent by a second communication node; and initiating, according to a comparison result of the relay function configuration information and a first current parameter value, a relay function corresponding to the comparison result, where the first current parameter value includes a measurement value and a traffic priority.
