Abstract: An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: receive (1400) a request to create context for a migrating node and optionally at least one child node of the migrating node; allocate (1402) addresses to the migrating node and optionally the at least one child node of the migrating node; and send (1404) the addresses allocated to the migrating node and optionally the at least one child node of the migrating node, prior to the migrating node migrating from a source to a target.

Abstract: Embodiments of the present disclosure relate to for inter-CU topology adaptation. A first device establishes a communication interface between the first device and a second device. The first device receives from the second device a handover complete message indicating that a handover of the second device from a third device to the first device is completed. The first device transmits to the second device a command indicating the second device to activate cells configured by the first device.

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.

Abstract: A method for adjusting transmit timing is disclosed. The method includes determining a reference timing advance value TA ref , receiving a time offset parameter; and adjusting downlink transmit timing based on i) detected downlink receive timing of a radio node and ii) the reference timing advance value TA ref and the time offset parameter.

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.
