Abstract
A transmission rate determining method that enables assignment of transmission rate (modulation scheme and coding rate) to be optimized with high accuracy in the AMC technique. In the method, in a base station, Doppler frequency detectordetects the Doppler frequency (moving speed) of each mobile station. MCS assignment sectioncorrects a relational expression of MCS (coding rate and modulation scheme) and CIR based on the Doppler frequency (moving speed) obtained in Doppler frequency detector, for example, corrects a threshold in CIR, and determines MCS optimal for CIR report value. Results of assignment in MCS assignment sectionare output to coding sectionand modulation section
