Claim 3:
4. A method implemented by a child integrated access backhaul (IAB) node that is configured to communicate with a first parent IAB node and a descendant IAB node over a backhaul network, the method comprising:
detecting a backhaul link failure between the child IAB node and the first parent IAB node;
in response to the detected backhaul link failure, causing transmission of a radio link failure indication to the descendant IAB node, the radio link failure indication being configured to cause each descendant IAB node in an established communication path receiving the radio link failure indication to modify data transmission and remain on the established communication path to the child IAB node;
receiving signaling indicating for the child IAB node to connect to a second parent IAB node; and
modifying network topology at least in part by connecting to the second parent IAB node.
