Abstract

This invention discloses a relay amplification device with the TR control function including: a coupling unit and a working state control unit, in which, the coupling unit couples the RF signals from the base station to a first TR switch unit and a working state control unit separately, which controls the conduction of the up-link of the relay amplifying device based on the RF signal received from the base station, its power amplification, cut-off and close of the power amplifier of the down-link or controls the down-link conduction and its power amplifier, the cut-off of the up link and shutof its power amplifier, besides, this invention also provides a control method for TR signals of the relay amplification device.

Description

technical field [0001] The invention relates to a time-division multiplexing wireless communication system, in particular to a relay amplifying device and a transmitting-receiving control method in the time-division multiplexing wireless communication system. Background technique [0002] In a wireless communication system, since the wireless terminals may be distributed widely, the wireless signals of the base station can only cover the wireless terminals within a certain range. If it is necessary to cover a larger range, it is necessary to add a relay amplifier (also called a trunk amplifier) ​​between the base station and the far coverage area to perform relay amplification on the wireless signal. [0003] Depending on the working mode of the wireless communication system, the working principle of the applied relay amplifier is also different. Currently, there are mainly two working modes of uplink and downlink in the wireless communication system: FDD (Frequency Divisio...
