The invention relates to a method for supplying reference data that is to be used in a mobile station of a radio communications network for a frequency update of the frequency used by the mobile station, which reference data is based on bursts received by the mobile station from a base station of said radio communications system. In order to allow for an improved supply of reference data to an automatic frequency correction algorithm, it is proposed that the method comprises determining the signal-to-noise-ratio of all bursts received unless they were discarded by some selection process; and providing at least some of the bursts for which a signal-to-noise-ratio greater than a predetermined value was determined as basis for the reference data to be used for the frequency update. The invention equally relates to a mobile station, a module and a radio communications system comprising the corresponding means.
