Claim 17:
18. A method implemented at an integrated access backhaul, IAB, node, which has a neighboring IAB node having a downstream hop to the IAB node, the method comprising:
determining whether at least partial of resources within the IAB node range of scheduling delay is scheduled by the neighboring IAB node, wherein the IAB node range of scheduling delay is determined based on an end point of uplink grant transmission or downlink assignment transmission and at least one of a first delay threshold for the IAB node and a second delay threshold for the neighboring IAB node, wherein the first delay threshold is preconfigured in the IAB node or received from a management node, and wherein the second delay threshold is preconfigured in the IAB node or received from the neighboring IAB node;
if at least partial of the resources within the IAB node range of scheduling delay is scheduled by the neighboring IAB node, reserving the recourse scheduled by the neighboring IAB node; and
scheduling an uplink transmission or downlink reception with the unscheduled resource within the IAB node range of scheduling delay.
