Claim 0:
1. A method performed by a final Integrated Access and wireless access Backhaul (IAB) node of a wireless communications network with respect to a traffic flow for a user equipment (UE) connected wirelessly to the final IAB node, wherein the traffic flow traverses a multi-hop path including one or more intermediate IAB nodes coupling the final IAB node to a donor IAB node, and wherein the method comprises:
receiving data packets of the traffic flow from a last one of the one or more intermediate IAB nodes along the multi-hop path, the data packets carrying marking applied by each intermediate IAB node that is experiencing congestion with respect to transmitting the data packets along the multi-hop path; and
transmitting a report to the donor IAB node based on the marking, wherein the report indicates that at least one of the one or more intermediate IAB nodes is experiencing congestion with respect to transmitting the data packets along the multi-hop path.
