Abstract
A method for performing a beamformed transmission and/or reception in a wireless communication using an antenna array comprising a first sub-array of first antenna elements each having a first polarization and a second sub-array of second antenna elements each having a second polarization that is orthogonal to the first polarization is provided. The method comprises obtaining a first weight vector for the first sub-array and a second weight vector for the second sub-array. The first weight vector and the second weight vector optimize a utility function. The utility function comprises a first term depending on a first function of the first weight vector and on a second function of the second weight vector. The utility function further comprises a second term depending on either one of the first function and the second function. Performing the beamformed transmission using the obtained first weight vector and the second weight vector.
