US 2021/0345163 A1 · LATENCY MANAGEMENT FOR INTEGRATED ACCESS AND BACKHAUL

Abstract

Technology for an Integrated Access and Backhaul (IAB) node in an IAB network is disclosed. The IAB node can 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. The IAB node can encode, at a mobile terminal (MT) of the IAB node, a second resource request for transmission to the parent IAB node or the 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.

Dependent claims

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
a memory interface configured to send to a memory the first resource request.

3 more elements

At least one 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;
and
encoding, at a mobile terminal (MT) of the IAB node, a scheduling request (SR) for transmission to a parent IAB node or a 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.
