| Title of Invention | METHOD AND APPARATUS FOR REPEATING WIRLESS SIGNALS BIDIRECTIONALLY AND SYNCHRONOUSLY |
|---|---|
| Abstract | The present invention provides a wireless signal bi-directional synchroniz ion forwarding method and device for use in a time division duplexing (TDD) wireless communication system , which can bi-directional synchronization forward the wireless signals transmitted by a base station and a terminal device in the system. Said device include a receive and transmit wireless section, a bi-directional frequency selection and radio-frequency amplification circuit as well as synchronization extraction and control means. At first, said receive and transmit wireless section receives and forwards the wireless signals transmitted by said base station and said terminal device. And then said synchronization extraction and control device extracts synchronization control information froin the wireless signals trasmitted by said base station, which can control said bi-directional frequency election and radio-frequency amplification circuit to synchronization forward the, bi-directional received signals. The present invention can realize the synchronization forwarding for the bi-directional received signals without delaying the receive d transmit time, and also has a system failure monitoring function to ensure reliable operation of the system devices. |
