The method implies that one for the signal quality optimal channel selection is predicted on the basis of a measured momentary fading of the transmitted signal. The mobile unit or the base unit performs signal strength measurements on the channels which are correlated with the carrier for which time access is to be performed. The obtained measurement values are averaged over a short period of time, whereafter the fading is calculated as the difference between the momentary signal strength value and the measured average. Channel selection for the next, following packet transmission is after that decided in a way that a channel with negative fading margin is avoided. The decision is based on prediction of unsuitable channel. |
