Abstract

The invention relates to a radio system including transceivers. One of the transceivers includes, for instance, a device for comparing a parameter representing signal quality measured from the received signal with at least one threshold value and a device for determining a quality class for the performance of a MIMO common channel. At least one of the transceivers includes a device for storing the observations made by the second transceiver about the quality class transitions of the transfer channel of the first transceiver and a device for estimating the next quality class of the transfer channel of the first transceiver from the stored quality class transition observations.
