Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for transferring traffic in integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, a first Central Unit-Control Plane (CU-CP) of a first IAB donor transmits, to a second CU-CP of a second IAB donor, a request to transfer target traffic via a Distributed Unit (DU) of the second IAB donor. The request comprises first information of the target traffic. The first CU-CP receives, from the second CU-CP, second information to be used for configuring the target traffic. This solution can improve the reliability and robustness of the IAB communication.

Abstract: Embodiments of the present disclosure relate to mechanism for cell identity management. According to embodiments of the present disclosure, a source device obtains identity information of a target device. The source device further obtains mapping from old cell ID to new cell ID for a migrating device and descendant devices of the migrating device. The mapping information receives from the target device or the migrating device. In this way, the device may be migrated to the target device without interrupting services of the terminal device which connects to the device.

Abstract: It is provided a method, comprising monitoring if a request for a handover of a platoon leader from a source cell to a target cell is received, wherein the request for the handover comprises a description of the required resources for platoon leader and all platoon members; and the method further comprises configuring the platoon leader and the platoon members with a new resource allocation if the request for the handover is received; informing the source cell on the new resource allocation and reserving or pre-reserving the resources in at least one of the source and target cell; supervising if the trigger event has occurred; activating the new resource allocation in the platoon leader and the platoon members if the activation command is received.
