Abstract
【解決手段】本発明においては、DeNBが複数のプロトコル層を有し、各プロトコル層は別のノードのプロトコル層に接続する。各プロトコル層の送信側は、受信側から受信した受信状態報告情報に基づいて、受信側が正常に受信したと通知してきたデータブロックを削除する。また、各プロトコル層の送信側は、受信側から受信した受信状態報告情報に基づいて、受信側が正常に受信していないと通知してきたデータブロックを再送する。そして、各プロトコル層の受信側は、正常に受信していないデータブロックがある場合、これを受信状態報告情報を利用して送信側に通知する。
【選択図】図13
Description
・該当PDUがデータPDUであるか制御PDUであるかを示す。
・制御PDUの種類を示す。
・000はPDCP状態報告、001はヘッダ圧縮帰還情報、残りの値は保留されている。
・受信側が受信していない最初のPDCP SDUのSN。
・Bitmapフィールドの該当ビットの位置が0のときは受信失敗、1のときは受信成功を示す。
