A mobile station compares a third evaluation function value calculated by the same algorithm as an evaluation function calculation algorithm used by a base station and corresponding to a current radio transmission path environment with a second evaluation function value reflecting terminal selection results in a past fixed period notified from the base station. If the third evaluation function value is not less than the second evaluation function value, the mobile station transmits a channel quality indication (CQI) to the base station. In contrast, if the third evaluation function value is smaller than the second evaluation value, the mobile station controls to stop the transmission of the CQI.
