The present invention relates to a method for sending channel quality information in a multi-carrier radio communication system comprising at least one mobile terminal and at least one base station, said channel quality information being sent on a signaling channel by said mobile terminal to said base station. According to the present invention, the method comprises the steps of: performing channel quality measurements on a plurality of frequency sub-carriers; generating and sending a first report over said signaling channel, said first report comprising a first channel quality information depending on said channel quality measurements on at least one sub-carrier, said at least one sub-carrier building an herein called first group of sub-carriers; determining a number of additional reports depending on the mobility grade of said mobile terminal; if said number of additional reports is not reached, generating and sending an additional report over said signaling channel comprising an additional channel quality information depending on channel quality measurements on at least one sub-carrier, said at least one sub-carrier building an herein called second group of sub-carriers, said second group of sub-carriers being different of said first group of sub-carriers.
