Abstract:
1. A method of coordinating polarizations of a first radio device with polarizations of an additional radio device, wherein the polarizations are generated by an antenna configuration comprising at least two orthogonally polarized antennas, and wherein the first and additional radio devices communicate wirelessly with at least one further radio device, the method being performed by the first radio device and comprising: 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 at least one of said further radio devices; and coordinating the defined polarizations with polarizations of the additional radio device based on the determined polarization and interchanging the defined polarizations when there is an indication of a polarization mismatch.
