Abstract

　適応変調処理または適応チャネル割り当てを行なう際に必要な受信品質情報を効率的に伝送し、実際の通信に使用するリソースを十分に確保する。移動局１００において、複数の通信チャネルの受信品質情報を測定し、各通信チャネルの受信品質情報に二次元変換処理を行ない、二次元変換処理後の一部の空間周波数成分を低減または削除し、低減または削除後のデータを用いて品質通知情報を生成する一方、基地局２００において、移動局１００で上記品質通知情報を生成する際に低減または削除された空間周波数成分の対応部分にダミーデータを追加し、追加後の品質通知情報に逆二次元変換処理を行ない、逆二次元変換処理後のデータを複数の受信品質情報として使用し、例えば、スロット割り当てや適応変調処理等を行なう。
