Abstract

　下り送信データに対し、無線リソースを複数のユーザ間でダイナミックに利用する無線通信方式に基づくスケジューリング処理により、該無線リソースを構成するサブキャリア周波数ブロックの割当を行う。該割り当てたサブキャリア周波数ブロックのサブフレームデータを送信し、これに対して受信した再送要求信号をエラー検出として記録する。そして、該記録したエラー検出が特定のサブキャリア周波数ブロックで継続して発生しているとき、該サブキャリア周波数ブロックに障害が発生していると判定する。上り受信データの場合には、同様に割り当てたサブキャリア周波数ブロックで上りサブフレームデータを受信し、そのエラー検出を記録する。そして、記録したエラー検出が特定のサブキャリア周波数ブロックで継続して発生しているとき、該サブキャリア周波数ブロックに障害が発生していると判定する。
