An electronic device on side of user equipment, with an access link between the user equipment and a first node of an integrated access and backhaul (IAB) system, there being a backhaul link between the first node and a second node of the IAB system, wherein the second node is a parent node of the first node in network topology of the IAB system, characterized in that the electronic device includes: processing circuitry that measures a signal inference from a third node; reports an interference measurement to the first node; and in a case where the second node makes a determination to switch the access link used by the user equipment based at least in part on the interference measurement exceeding a predetermined threshold, establishes a direct access link between the user equipment and the second node and disconnect the access link between the user equipment and the first node.
