Abstract (en)

[origin: WO2020086316A1] An apparatus of an Integrated Access and Backhaul (IAB) node includes processing circuitry coupled to memory. To configure the IAB node for resource assignment associated with a distributed unit (DU) child link with a child IAB node, the processing circuitry is to perform monitoring of physical downlink control channel (PDCCH) transmissions on a parent backhaul link between a mobile termination (MT) function of the IAB node and a DU function of a parent IAB node. A non-scheduled time resource for the parent backhaul link is detected based on the monitoring. Data is encoded for a downlink transmission from a DU function of the IAB node on the DU child link, the downlink transmission using the detected non-scheduled time resource.
