Claim 16:
17. A first integrated access and backhaul, IAB, node for performing IAB in a cellular telecommunications network that comprises the first IAB node and a second IAB node, the first IAB node comprising processing circuitry, the processing circuitry causing the first IAB node to:
schedule, in a first phase, downstream backhaul data from the first IAB node to the second IAB node; and
receive, in a third phase, from the second IAB node, upstream backhaul data as scheduled by the second IAB node;
wherein:
the downstream backhaul data of the first phase is acknowledged or negatively acknowledged by the second IAB node in the third phase, or
the upstream backhaul data of the third phase is acknowledged or negatively acknowledged by the first IAB node in a subsequent first phase, or
both the downstream backhaul data of the first phase is acknowledged or negatively acknowledged by the second IAB node in the third phase and the upstream backhaul data of the third phase is acknowledged or negatively acknowledged by the first IAB node in the subsequent first phase.
