Abstract There is provided a method in a network node for controlling multiple input multiple output antenna system, the method including obtaining a plurality of time domain symbols to be transmitted, the plurality of time domain symbols including time domain symbols to be broadcasted via the multiple input multiple output antenna system; determining a mapping between the plurality of time domain symbols and parameters of control units associated with respective antenna elements of the multiple input multiple output antenna system, each control unit including a phase shifter, wherein the parameters control values of the phase shifters, and wherein the mapping is performed based on an algorithm for minimizing distortion and/or bit error rate at receiving user equipment; causing applying the parameters at the control units; and causing transmission of the plurality of time domain symbols via the multiple input multiple output antenna system.
