Problems solved by technology

If the conversion time of sending and receiving signals is long, a large delay will be required, which is difficult to realize by using SAW (Surface Acoustic Filter), and the fixed delay may produce certain errors. At the same time, in the wireless resource arrangement of the system, there will be Causes inconsistencies between allocation and actual use

Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] First refer to figure 2 , figure 2 It is a schematic diagram of the networking mode of the device for bidirectional synchronous forwarding of wireless signals and the system base station in the present invention. In a wireless communication system network, a network maintenance center usually maintains the normal operation of multiple base stations, and each base station corresponds to multiple devices of the present invention for bidirectional synchronous forwarding of wireless signals, through which the wireless transmission of base stations and terminals Two-way synchronous forwarding of signals is used to improve the quality and coverage of signals transmitted by the base station in different directions; and each device of the ...

Abstract

The device includes receiving and retransmitting radio signal emitted from base station and terminal equipment by transceiving antenna, picking up synchronous control information from radio signal ofthe base station by synchronous picking up and detecting control unit to control synchronous retransmitting and to carry out fault minitoring from frequency selective-radio frequency amplifier circuit to two-way receiving signal. The present invention does not need time delay for the received signal so not only synchronous retransmitting of two-way receiving signal can be realized but also detecting function of system fault can be executed.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for bidirectional synchronous forwarding of wireless signals. Background technique [0002] At present, with the improvement of communication technology, not only traditional frequency division duplex (FDD) wireless communication systems such as GSM (Global System for Mobile Communications), IS95 (narrowband CDMA system series standards) have developed very rapidly, but also time division duplex (TDD) wireless communication system, due to its flexible frequency arrangement, does not need to arrange paired frequencies, and the system equipment is simple, it has also begun to be more widely used. In the wireless communication system adopting TDD mode, reception and transmission are in different time slots of the same frequency channel (carrier), and the guaranteed time is used to separate the reception and transmission channels (or uplink and downlink). ...
