Abstract: According to an embodiment, a method may include receiving, by a target network entity, at least one message from an integrated access and backhaul node. The method may further include receiving at least one handover request. The method may further include associating, based on the at least one message and the at least one handover request, by the target network entity, at least one mobile termination of at least one integrated access and backhaul node with at least one distributed unit of the at least one integrated access and backhaul node.

Abstract: According to a first embodiment, a method may include receiving, by a source network entity, a trigger. The method may further include, in response to receiving a trigger, generating, by the source network entity, at least one adaptation layer status report indicating at least one adaptation layer protocol data unit. The method may further include transmitting, by the source network entity, the at least one adaptation layer status report to a target network entity.

Abstract: Disclosed are methods for controlling downlink transmissions in an integrated access and backhaul network. An example method may include determining to control a first downlink transmission for a first interface between a second apparatus associated with a user plane of the central unit of the donor and a node in the integrated access and backhaul network, and transmitting, to the second apparatus, a first non UE-associated signaling request to control the first downlink transmission for the first interface, the first non UE-associated signaling request including information associated with the node. Related apparatuses and computer readable media are also disclosed.

Abstract: A technique of performing a handover procedure involves providing a proper timing adjustment indication for the UE performing RACH-less HO. Even though the discussion herein is on IAB scenarios and the idea takes an advantage of IAB nodes being in fixed locations (i.e., not moving in the network), it can be applied to UEs in general. The timing adjustment provided in performing a HO in an IAB network according to the improved techniques involves computing a timing advance (TA) to be used by an IAB node prior to executing HO to an alternative serving node. Such a use of a TA may enable a bypassing of a RACH procedure when accessing a cell.
