Claim 0:
1. An apparatus of an Integrated Access and Backhaul (IAB) node in an IAB network, the apparatus comprising:
one or more processors configured to:
decode, at a distributed unit (DU) of the IAB node, a first resource request received from one of a user equipment (UE) or a child IAB node, wherein the first resource request is associated with the UE; and
encode, at a mobile terminal (MT) of the IAB node, a second resource request for transmission to a parent IAB node or a IAB donor triggered by receipt of the first resource request, wherein the second resource request is transmitted prior to a receipt of a protocol data unit (PDU) at the DU of the IAB node; and wherein the second resource request is a predictive buffer status report (pBSR) that includes a default nominal size of resource allocation that accommodates a control plane message and a buffer status report (BSR) when no BSR is received from the UE or the child IAB node; and
a memory interface configured to send to a memory the first resource request.
