Abstract

The invention discloses a method, a device and a relay device for detecting the position of a synchronization point and a switch point, which are used to solve the problem in the prior art that the relay device can only obtain the position information of the synchronization point and the switch point from other devices. The present invention couples the radio frequency signal received by the relay device in the downlink direction, performs power detection after isolation processing in the uplink direction, compares the detected voltage signal with a preset threshold, and determines the synchronization point of the current wireless subframe according to the comparison result and the position of the dynamic switch point, and control the transmitting and receiving working state of the relay equipment by using the determined synchronization point and the position of the switching point, so as to realize the dynamic time-division bidirectional amplification of the TD-SCDMA relay equipment.

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...
