摘要：Controlling the polarization state of signals to be transmitted from a MIMOcapable radio base station node to a plurality of user equipment, which radio base stationnode comprises a precoder unit connecting a first and a second virtual antenna port to arespective first and second transmit antenna port, by the steps of controlling (S10) arelative phase between transmitted signals from the first and second transmit antennaport to provide a predetermined pair of orthogonal polarization states for signalstransmitted on the first and second virtual antenna ports, and interchanging (S20) thepolarization states of the first and second virtual antenna ports, to provide transmittedpolarized signals with alternating polarization states.
