Abstract
There is provided beam forming using a dual polarized antenna array. A first set of reference signals for acquiring channel state information is alternatingly transmitted using a dual polarized antenna array in a first polarization direction and in a second polarization direction, respectively. Quantized channel information based on the first set of reference signals is received from a radio transceiver device. Angular information relating to the radio transceiver device is determined based on the quantized channel information. Transmission beams for transmission to the radio transceiver device are determined. The transmission comprises precoder vectors and have relative orthogonal polarizations for beam forming according to the angular information.
