Abstract

See full text

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