    • A hybrid automatic repeat request method of the downstream tunnel comprises the steps: the base station transmits the tunnel data of the protocol data unit comprising a plurality of terminals to the access relay station via the tunnel link, and receives the feedback from the relay station until the access relay station receives the data correctly; the access relay station analyzes the protocol data unit of each terminal from the tunnel data, transmits the protocol data unit of each terminal to the corresponding terminal, and makes the corresponding process after receiving the feedback from each terminal. Of which, the tunnel link is composedby multi-hop relay stations. The relay station accessing the base station is the first hop relay station, and the relay station accessing the terminal is the nth hop relay station. Of which, the first hop, the second hop, , the n-1th hop relay station will not transmit the reception acknowledgement message immediately after receiving the tunnel data. The corresponding process after the access relay station receives the feedback of each terminal is uploading the feedback of the terminal to the base station or not uploading the feedback but requesting to re-transmit the bandwidth according to the feedback of the terminal.
