RADIO COMMUNICATION TERMINAL DEVICE, RADIO COMMUNICATION BASE STATION DEVICE, AND CQI FEEDBACK METHOD
摘要
<p>It is possible to provide a radio communication terminal device, a radio communication base station device, and a CQI feedback method which can improve the CQI reproducibility while reducing the feedback overhead. A terminal channel judgment unit judges whether a local terminal is a TU terminal or a LOS terminal. A feedback CQI decision unit selects a Best-M report if the local terminal is the TU terminal, and selects a DCT report if the local terminal is the LOS terminal. The feedback CQI decision unit feeds back the CQI by using the selected report method.</p>
