A method for relaying and forwarding feedback information in hybrid automatic repeat request scenario, and the method applies to a communication link which is formed between a multi-hop relay base station and a mobile station by the relay of at least a relay station, wherein the method comprises: the relay station, in the process of sending downlink data to a subordinate node, receives a resource allocation message from a superordinate node indicating the relay station to receive feedback information of the subordinate node in the i th frame; if having received the feedback information in the i th frame, the relay station sends upwardly the feedback information to a multi-hop relay base station in the (i+j) th frame through the uplink feedback channel allocated by the multi-hop relay base station, (S308a) if the relay station has not received the feedback information in the i th frame, the relay station sends upwardly the information for notifying the multi-hop relay base station of the hop at which retransmission occurs in the (i+j) th frame through the uplink feedback channel, wherein j is the time delay resulting from processing the feedback information by the relay station; (S308b) the relay station, in the process of sending uplink data to the superordinate node, receives a resource allocation message from the superordinate node indicating the relay station to send the uplink data in the i th frame; if having received the uplink data correctly, the relay station sends upwardly to the superordinate node in the i th frame the information for notifying the superordinate node that the relay station has successfully received the uplink data and the uplink data respectively through the uplink feedback channel and the transmission channel allocated by the multi-hop relay base station; (S408a) if not having received the uplink data successfully, the relay station sends the information upwardly for notifying the multi-hop relay base station of the hop at which retransmission occurs through the uplink feedback channel in the i th frame (S408b). the relay station, in the process of sending downlink data to a subordinate node, receives a resource allocation message from a superordinate node indicating the relay station to receive feedback information of the subordinate node in the i th frame; if having received the feedback information in the i th frame, the relay station sends upwardly the feedback information to a multi-hop relay base station in the (i+j) th frame through the uplink feedback channel allocated by the multi-hop relay base station, (S308a) if the relay station has not received the feedback information in the i th frame, the relay station sends upwardly the information for notifying the multi-hop relay base station of the hop at which retransmission occurs in the (i+j) th frame through the uplink feedback channel, wherein j is the time delay resulting from processing the feedback information by the relay station; (S308b) the relay station, in the process of sending uplink data to the superordinate node, receives a resource allocation message from the superordinate node indicating the relay station to send the uplink data in the i th frame; if having received the uplink data correctly, the relay station sends upwardly to the superordinate node in the i th frame the information for notifying the superordinate node that the relay station has successfully received the uplink data and the uplink data respectively through the uplink feedback channel and the transmission channel allocated by the multi-hop relay base station; (S408a) if not having received the uplink data successfully, the relay station sends the information upwardly for notifying the multi-hop relay base station of the hop at which retransmission occurs through the uplink feedback channel in the i th frame (S408b).
