Abstract:
An object of the present invention is to enable coordination of VP/HP polarizations generated by cross-polarized, i.e. orthogonally polarized antenna configurations, of one radio device with another radio device. The object is achieved by a method in a first eNB (100c) of coordinating polarizations of the first eNB with polarizations of an additional eNB (100a). The polarizations are generated by an antenna configuration comprising at least two orthogonally polarized antennas. The first and additional eNB (100c, 100a) communicate wirelessly with a UE (150a). The method comprises the steps of establishing a first amplitude and/or phase offset of the antenna configuration generating a vertical or horizontal polarization, and a second amplitude and/or phase offset of the antenna configuration generating a polarization orthogonal to said polarization generated by the first amplitude and/or phase offset, defining the polarization generated by the first amplitude and/or phase offset to be vertical and the polarization generated by the second amplitude and/or phase offset to be horizontal, determining a polarization of the UE, and coordinating the defined polarizations with polarizations of the additional eNB based on the determined UE polarization.
