Abstract
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable media for communication during inter-donor topology adaptation. A first device transmits, to a second device, first information about a first communication interface between the first device and a third device, receives, from the second device, an indication that context information associated with at least one fourth device and the first communication interface is retained, and uses the context information in communication via a second communication interface between the first device and the second device. The second device receive the first information, transmit, to the third device, a request for obtaining the context information, and receive the context information from the third device. In this way, reestablishment procedure can be simplified, and signaling over Xn interface, F1 interface and wireless backhaul can be minimized Further, latencies and service break for the terminal devices at the change of the IAB-donor can be reduced.
