<p><P>PROBLEM TO BE SOLVED: To obtain a base station device which achieves high-speed throughput by improving data transmission efficiency. <P>SOLUTION: The base station device determines an MCS to be used for adaptive modulation based on a CQI value included in a reception signal and comprises: a correction section (5) which corrects the CQI value in accordance with variations of a transmission line state with the lapse of time from a point of time when a mobile station measures the transmission line state, to a point of time when actually transmitting data after the adaptive modulation; and an MCS determination section (8) which determines the MCS based on the corrected CQI value. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
