Abstract

　再送に必要な通信リソースを減少させてデータ伝送効率を向上させることができる無線通信装置。この装置において、再送判定部（１０９）は、誤り検出部（１０７）からＮＡＣＫ信号が入力された場合、すなわち、受信データに誤りが有る場合、ＬＤＰＣ復号部（１０６）から入力される復号ビット列を検査行列の列重みの大きさに応じて分割して構成される複数のブロックにおいて、各ブロックに含まれる各復号ビットのＬＬＲの平均値に基づいて、ブロックの再送が必要か否かをブロック毎に判定する再送判定処理を行う。また、再送判定部（１０９）では、複数のブロックのうち、列重みが大きいブロックから順に判定され、あるブロックの再送が必要と判定された時点で、まだ再送が必要か否かを判定されていないブロックの判定を行わないようにする。そして、制御信号生成部（１１０）は、再送判定部（１０９）から入力された判定結果に基づいてフィードバック情報を生成する。
