Abstract
Power control can be employed, whereby a power control adjustment can be determined by a relay distributed unit (DU) device, based on a measurement of the power level of received access uplink transmissions, and a measurement of the power level of a reference signal received from a donor DU via a backhaul downlink transmission. The power control adjustment can be transmitted to the donor distributed unit device, which uses the power control adjustment to reduce the amount of power of downlink transmissions to the relay distributed unit device.
