Claim 9:
10. A method performed by an Integrated Access and wireless access Backhaul (IAB) node of a wireless communications network operating as one of one or more intermediate IAB nodes with respect to a traffic flow for a user equipment (UE) connected wirelessly to a final IAB node, wherein the traffic flow traverses a multi-hop path that includes the one or more intermediate IAB nodes coupling the final IAB node to a donor IAB node, and wherein the method comprises:
detecting that the IAB node is experiencing congestion with respect to transmitting data packets of the traffic flow along the multi-hop path; and
responsive to detecting the congestion, marking one or more affected data packets of the traffic flow, so that the final IAB node is aware of the congestion.
