Abstract
Each of a mobile station and a base station stores a Wideband CQI table and a Subband CQI table. At the mobile station, a control unit transmits a CQI report value indicating Wideband CQI, and an index (Index S) indicating a differential value of a Diff reference value based on the CQI report value and Subband CQI, on the basis of the tables. In addition, the control unit makes the Diff reference value variable to prevent an expression amount of the index from being damaged if the Wideband CQI report value is in a range close to an upper lit or a lower limit of the Wideband CQI table.
