Transceiver method in a radio system and a radio system

A transceiver method in a radio system in which several antennas are used in signal transmission and/or reception propagating through a radio channel, and which radio system comprises a transceiver of a first type and at least one transceiver of a second type,

• the method comprising:
• transmitting a signal of at least one type by the transceiver of the second type by using at least one antenna;
• receiving a signal by the transceiver of the first type by using at least two antennas of different polarizations;
• performing measurements of the received signal by the transceiver of the first type to determine the polarization of the received signal;
• signalling the measuring data by the transceiver of the first type to the transceiver of the second type;
• determining the polarization of the transceiver of the second type on the basis of the measuring data received from the polarization determination measurements of the received signal;
• adjusting the signal transmitted by the transceiver of the second type in such a way that the polarization of the signal is matched with the polarization used by the transceiver of the first type;
• transmitting at least two polarization-matched signals by the transceiver of the second type, which polarization-matched signals are polarized orthogonally relative to each other;
• receiving the polarization-matched signals by the transceiver of the first type by using at least two antennas of different polarizations.

A radio system comprising at least two transceivers which comprise several antennas for transmission and/or reception of a signal propagating through a radio channel,

• at least one of the transceivers further comprising:
• means for generating signals polarized in at least two different manners;
• means for transmitting at least two signals polarized in different manners;
• means for receiving at least two signals polarized in different manners;
• means for performing measurements of the received signal to determine its polarization;
• means for adjusting the transmitted signals on the basis of the polarization of the received signal, determined based on the measuring data, in such a way that the polarizations of the at least two transmitted signals of different polarizations are matched with the polarization used by another tranceiver.
