ABSTRACT:
Disclosed are a method and system for generating switching a timing signal for separating a transmitting and receiving signal in a RF repeater of a mobile telecommunication network by using a TDD scheme and an OFDM modulation scheme, which transmits a part of a RF signal extracted from a coupler of a RF repeater to a switching timing signal generating circuit when a RF signal transmitted from an Access Point (hereinafter, referred to as “AP”) is transmitted to a RF repeater, locates a frame start position of a RF signal by correlating a reference signal generated in a switching timing signal generating circuit and a RF signal extracted from a coupler, and is capable of transmitting a RF signal by distinguishing between a downlink signal and a uplink signal by using a switching timing signal in a switch when calculating a starting point of a downlink signal and a uplink signal which is included in an RF signal by using an AP's frame standard on the basis of a frame starting location, and transmitting to a RF repeater's switch generating a switching timing signal by using it.
