1. An electronic device configured to operate as a user equipment, there being an access link between the user equipment and a first node of an integrated access and backhaul (IAB) system, the access link between the user equipment and the first node comprising an uplink access link between the user equipment and the first node and a downlink access link between the user equipment and the first node, 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, the electronic device comprising:
a processing circuitry configured to:
measure a signal interference from a third node and generate a corresponding interference measurement;
report the interference measurement to the first node; and
in a case where the second node makes a determination, based at least in part on the interference measurement exceeding a predetermined threshold, to switch the access link between the user equipment and the first node, establish a direct access link between the second node and the user equipment and disconnect the access link between the user equipment and the first node,
wherein disconnecting the access link between the user equipment and the first node comprises disconnecting only the downlink access link between the user equipment and the first node without disconnecting the uplink access link between the user equipment and the first node, and
wherein establishing the direct access link between the second node and the user equipment comprises establishing only a downlink access link between the second node and the user equipment without establishing an uplink access link between the user equipment and the second node.
