USING ALTERNATIVE PATHS OF DESCENDANT NODES FOR BACKHAUL-LINK FAILURE REPORTING IN INTEGRATED ACCESS

摘要

A method, system and apparatus are disclosed. According to one or more embodiments, a child IAB node (16b) is configured to communicate with a first parent IAB node (16) and a descendant IAB node (16c) over a backhaul network. The child IAB node (16b) includes processing circuitry (68) configured to: detect a backhaul link failure between the child IAB node (16b) and the first parent IAB node (16); in response to the detected backhaul link failure, cause transmission of a radio link failure indication to the descendant IAB node (16c); receive signaling indicating for the child IAB node (16b) to connect to a second parent IAB node; and modify network topology at least in part by connecting to the second parent IAB node.
