Claim 12:
13. A descendant integrated access backhaul (IAB) node in communication with a donor IAB node via at least a first parent IAB node and a child IAB node over a backhaul network, the descendant IAB node comprising:
processing circuitry configured to:
receive a radio link failure indication;
in response to the radio link failure indication:
modify data transmission and remain on an established communication path to the child IAB node; and
cause transmission of the radio link failure indication to the donor node;

receive signaling from the donor IAB node, the signaling indicating for the child IAB node to modify network topology at least in part by connecting to a second parent IAB node; and
cause transmission the signaling to the child IAB node.
