Abstract
The invention discloses a hybrid automatic repeat request method of a downlink tunnel connection in a multi-hop relay system. The base station transmits tunnel data, comprising of protocol data, to the access relay station via the tunnel link, and receives feedback until the access relay station receives the data correctly. The access relay station analyzes the protocol data unit of each mobile station, transmits the protocol data to the corresponding mobile station, and performs the corresponding process after receiving feedback from each mobile station. Each hop relay station, except for the station accessing the mobile station, will not transmit the reception acknowledgment information to the base station immediately. The corresponding processing after the access relay station receives the feedback is transmitting the feedback from the mobile station to the base station or, not transmitting the feedback, but applying for bandwidth for retransmission according to the feedback of the mobile station.
