Abstract

An apparatus and a method are disclosed by which transmit power for each antenna element of an antenna array for beamforming is determined by determining a weight vector including a weight for each antenna element according to a specific beamforming procedure, it is detected whether at least one of the plurality of antenna elements is saturated, wherein an antenna element is saturated when the determined transmit power for this antenna element is higher than a threshold, and, when it is detected that there is at least one saturated antenna element, the transmit power for each antenna element of the antenna array is adjusted such that a part of the transmit power allocated to the at least one saturated antenna element is allocated to at least one antenna element of the antenna array which is not saturated based on the weight vector determined according to the specific beamforming procedure.
