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: The present disclosure describes methods, systems, and devices for updating configuration information for a downstream device of a migrating integrated access backhaul node (IAB-node) during an inter-donor migration from a source IAB-donor to a target IAB-donor. The method includes providing, by an IAB-donor central unit (CU), updated configuration information into system information which is contained in a system information block (SIB) other than SIB1 carried in a SystemInformation (SI) message, and encoding the system information with the updated configuration information. The method also include sending, by the IAB-donor CU, the system information including the updated configuration information as a radio resource control (RRC) container to a migrating IAB-node distributed unit (DU) via F1-AP. The method further includes the migrating IAB-node DU forwards the system information including the updated configuration information through a dedicated RRC message to the downstream device.
