An overhead accompanying feedback from a UE terminal is reduced. The UE terminal selects not only M subbands with high quality but also M subbands with poor quality. Alternatively, the UE terminal selects M subbands to be fed back by increasing a priority of a subband with a high degree to which the quality of the subband is to be improved by the feedback or a subband having a high possibility of unnecessary eNodeB being removed from the CoMP set by the feedback. In addition, the UE terminal performs measurement and feedback in units of subband groups which can be collectively handled. |
