Description
図4を参照すれば、TxRLCでTx HARQでRLC PDUを伝逹する(S100)。RLC PDUはMAC階層へ伝逹されて、ヘッダー情報が含まれる一つまたは多数のMACPDUに変換されることができる。MAC PDUが物理階層でHARQを介して伝逹するデータブロックとなる。Tx HARQはデータブロックをRx HARQに送信する(S110)。RxHARQは受信されたデータブロックにエラーが検出されなければACK信号をTx HARQに送信し、データブロックを上位階層、例えばRx RLCへ伝逹する。ただし、説明を明確にするために、RxHARQで受信されたデータブロックでエラーを検出することとする。
