    Abstract: The IAB node comprises receiver circuitry and processor circuitry. The receiver circuitry is configured to receive information on a resource allocation of OFDM symbols within one or more slots. The processor circuitry is configured to determine from the information both a slot format indicator and a time resource indication. The slot format indicator is configured to indicate, for each OFDM symbol of the slot, whether the symbol is an uplink symbol, a downlink symbol, or a flexible symbol. The time resource indicator, TRI, is configured to indicate, for each OFDM symbol of the slot, whether the symbol may be allocated by a parent node or by the IAB node. The processor circuitry is further configured to control utilization of one or more symbols of the slot at least in part in accordance with a respective symbol allocation from the time resource indication and the slot format indicator.
