    摘要: A cooperative apparatus and a frequency synchronization method thereof for use in a wireless network are provided. The wireless network comprises a base station and a subscriber station. The cooperative apparatus retrieves a signal from the base station and calculates a frequency offset between the base station and the cooperative apparatus according to the signal. Accordingly, the cooperative receives a cooperative information from the base station and forwards the cooperative information to the subscriber station based on the frequency offset.
