1. At least one non-transitory machine readable storage medium having instructions embodied thereon for operating an Integrated Access and Backhaul (IAB) node in an IAB network, the instructions when executed by one or more processors perform the following:
decoding, at a distributed unit (DU) of the IAB node, a buffer status report (BSR) received from one of a user equipment (UE) or a child IAB node, wherein the BSR is associated with the UE;
encoding, at a mobile terminal (MT) of the IAB node, a scheduling request (SR) for transmission to a parent IAB node or an IAB donor triggered by receipt of the BSR, wherein the SR is transmitted prior to a receipt of a protocol data unit (PDU) at the DU of the IAB node;
decoding, at the MT of the IAB node, a first uplink grant received from the parent IAB node or the IAB donor; and
encoding, at the MT of the IAB node, a predictive buffer status report (pBSR) for transmission to the parent IAB node or the IAB donor using the first uplink grant.
