Bi-directional synchronization forwarding method and device for wireless signals

The invention claims with disposed on the bidirectional synchronous forwarding to wireless signal method and device, AND is a time division duplex) in wireless communication system, base station and terminal device and system to the wireless signal emitting device and bidirectional synchronous forwarding, wherein the device comprises: Dual-mode the antenna group, the frequency selecting bi-directional wireless frequency amplifying circuit and synchronous and extracting monitoring device. Is received and retransmitted the wireless signal of a dual-mode antenna group the base station and terminal device, emittingWithdraw the synchronous control information control to the frequency bi-directional wireless frequency amplifying circuit synchronous from the wireless signal for base station transmission through the synchronous and extracting monitoring device to the bidirectional received signal to retransmit and a on the fault monitoring. The invention, no need to receiving and transmitting signal time and same, and realizing to the synchronous forwarding of bidirectional received signal; meanwhile with the system for monitoring function, comprising a ensuring reliability service system and device.
