1. An Integrated Access and Backhaul (IAB) node that communicates over a radio interface, the IAB node comprising:
mobile-termination circuitry configured to transmit over the radio interface with a parent node;
distribution circuitry configured to transmit over the radio interface with a child node; and
processor circuitry configured to manage transmission power utilized by the IAB node by taking into consideration both the transmission by the mobile-termination circuitry and the transmission by the distribution circuitry,
wherein the processor circuitry is further configured to determine the transmission power utilized by the IAB node by determining each of:
power utilization by the mobile-termination circuitry for transmission on a Physical Uplink Shared Channel (PUSCH);
power utilization by the mobile-termination circuitry for transmission on a Physical Uplink Control Channel (PUCCH);
power utilization by the distribution circuitry for transmission on a Physical Downlink Shared Channel (PDSCH); and
power utilization by the distribution circuitry for transmission on a Physical Downlink Control Channel (PDCCH).
