description According to an aspect, there is provided a beamforming processing apparatus for a radio transmitter or receiver including an antenna array. The beamforming processing apparatus includes circuitry configured for maintaining, in a database, information on radiation properties of the antenna array and probability density functions for target device positions. The radiation properties of the antenna array include beam parameters and a beam parameter dependent beam gain function. The beamforming processing apparatus includes circuitry configured for calculating cumulative distribution functions of beam gain based on the probability density functions and the beam gain function and based thereon one or more optimal values of beam parameters defining an optimal beam by maximizing a first optimization parameter defined based on the one or more cumulative distribution functions subject to a minimum value of a second optimization parameter.
