BASE STATION DEVICE AND COMMUNICATION CONTROL METHOD

摘要

A user device transmits feedback information which reports that multicast data and/or broadcast data do not satisfy a predetermined quality. A base station device which transmits multicast data and/or broadcast data to the user device includes: feedback information judging means which obtains the number of reports of the feedback information and judges whether to perform adaptive modulation/demodulation according to the number of reports; and MCS control means which modifies a combination of the modulation method and the channel encoding method to be applied to the multicast data and/or the broadcast data according to the judgment result obtained by the feedback information judgment means.
