Abstract

The present invention concerns a method for adjusting the frequency reference for a mobile station in a cellular type radio system, which mobile station comprises measuring elements for measuring the frequency error for a signal A received from a base station and elements for adjusting the frequency reference on the basis of the measured frequency error. In order to compensate for the Doppler frequency shift caused by the movement of the mobile station, the mobile station is arranged to measure the frequency error for signals received from at least two different base stations B, the mean value of the measured frequency error is calculated C, and the frequency reference of the mobile station is adjusted to minimise the calculated mean value E. <IMAGE>
