Abstract
A mobile communications system can easily set the optimum threshold for use in selecting a modulation-coding mode depending on a link condition. A selection control unit compares the reception quality of a common pilot signal detected by a mobile station with a plurality of thresholds stored in a threshold table, determines a modulation-coding mode to be selected, and outputs the determination result as a switch instruction. A threshold variable control unit variably controls the threshold level indicating the range of the link quality corresponding to the currently used modulation-coding mode based on the contents of the reception error notification from the mobile station.
