Abstract

　送信装置は、送信データを複数の符号ブロックに分割し、符号化して送信信号を生成する。送信装置は送信信号を送信し、受信装置は送信信号を受信信号として受信する。受信装置は、受信信号の複数の符号ブロックの各々に対して反復復号を施す。受信装置は、受信信号の複数の符号ブロックのうちの、第１設定反復回数に達する前に誤りが検出されなくなった第１符号ブロック群に対して反復復号を停止する。受信装置は、受信信号に誤りがある場合、ＮＡＣＫ情報と第１符号ブロック群を表す情報とを含む再送要求フィードバック情報を送信装置に送信する。送信信号の複数の符号ブロックの各々には、第１リソースが割り当てられている。送信装置は、再送要求フィードバック情報に応じて、送信信号の複数の符号ブロックのうちの、第１符号ブロック群のリソースを第１リソースよりも少ない第２リソースに割り当て、送信信号を受信装置に再送信する。
