Abstract

This invention discloses a method, a device and a relay device for testing position of synchronous point and switch point, which couples the RF signals received by the relay device in down direction to carry out power demodulation after up isolation to compare the demodulated voltage signal with a preset threshold and determines positions of synchronous point and dynamic switch point of the current radio sub-frame to control dispatch of the relay device based on the position of the synchronous point and switch point to realize dynamic time-sharing two-way amplification of TD-SCDMA relay device.

Description

technical field [0001] The present invention relates to a time division multiplexing wireless communication system, in particular to a method, device and relay equipment for detecting the positions of synchronization points and switching points in the time division multiplexing wireless communication system. Background technique [0002] In a wireless communication system, since the wireless signal of the base station can only cover wireless terminals within a certain range, if the base station needs to cover a larger range, it is necessary to add relay equipment (such as trunk amplifiers, repeaters, etc. Station, etc.), used to relay and amplify the wireless signal sent by the base station to increase the coverage of the base station. [0003] Depending on the working mode of the wireless communication system, the working principle of the applied relay device is also different. Currently, the uplink and downlink working modes in the wireless communication system are mainly...
