An uplink Hybrid Automatic Repeat reQuest (HARQ) method in a transparent relay network is provided according to embodiments of the present invention, which includes: a relay station intercepts and decodes uplink data sent from a mobile terminal to a base station; the relay station judges whether decoding of the uplink data is successful; when the relay station judges that the decoding of the uplink data is successful, the relay station sends acknowledgment response information to the base station to notify the base station that the relay station has received the uplink data successfully, and sends the acknowledgment response information to the mobile terminal when the base station does not decode the uplink data successfully; when the relay station judges that the decoding of the uplink data is successful and receives negative-acknowledgment information returned by the base station to the relay station, the relay station sends the intercepted uplink data to the base station, where the negative-acknowledgment information represents that the base station does not successfully decode the uplink data sent from the mobile terminal to the base station. Therefore, embodiments of the present invention can reduce power consumption of the mobile terminal. |
