METHOD FOR DETERMINING SWITCHING TIMING FOR COMPENSATING TIME DELAY OF TDD RF REPEATER AND RF REPEATER THEREFOR FOR USE IN WIBRO SYSTEM

摘要

The present invention relates to a switching time determination method, and the RF repeater therefor for time delay compensation of the TDD mode of the RF repeater in the WiBro system. ; Step of the present invention is a switching time determination method for time delay compensation of the RF repeater TDD scheme in the WiBro system, (a) to detect a transmission signal transmitted from the RAS in the RF repeater to the switch control portion of the RF repeater; (B) (a) analyzes the transmitted signal extracted in step detecting a frame start point of the transmitted signal; (C) calculating a downlink signal interval and the uplink signal interval included in the transmission signal based on the frame start point of the transmission signal and compensation determining a switching point in the time delay; (D) generating a switch control signal according to the switch point by passing a switch of the RF repeater; And (e) the downlink signal and the up-determined switching time method for a TDD system in the time delay compensating of the RF repeater, characterized in that to separate the link signals, including the step of transmitting and RF repeater therefor by the switch control signal to provide. ; According to the present invention, there is an effect that it is possible to correct the switching control by generating a switch control signal applied to the time delay compensation in the TDD scheme the RF repeater. ; WiMAX, mobile Internet, TDD, RF repeater, the switching control, the time delay compensation
