Abstract
A mobile terminal device for performing multi-carrier communication with a base station device can improve communication quality while reducing the data amount without lowering accuracy of feedback information. In the mobile station device (), a reception level measuring unit () measuring SINR as a reception level for each chunk formed by a plurality of sub-carriers according to a known signal; a control information transmission control unit () transmits feedback information (CQI information) based on the communication quality of each chunk to a base station device (); a relative value calculation unit () calculates a relative value of MCS corresponding to the reception level between adjacent chunks from the reception level of each chunk; and a CQI information generation unit () generates feedback information (CQI information) from an absolute value of MCS corresponding to the reception level of the reference chunk and a relative value of MCS corresponding to the reception level between the adjacent chunks.
