摘要
The present invention relates to a relay apparatus of the OFDM / TDD (Orthogonal Frequency Division Multiplexing / Time Division Duplex) scheme that, more specifically, the upper and the flavor will link signal control device is provided according to the OFDM / TDD system the relay device and the relay method. ; a direction link signal in accordance with the present invention the control device is provided with OFDM / TDD system relay device after detecting the synchronization of the OFDM / TDD frame input signal at the base station by using a CP (Cyclic Prefix), and, one of the synchronization detection unit for outputting a signal, an OFDM symbol period; And PLL apparatus that uses the main clock of the access point by using the output signal of the synchronous detection device to the main clock output generating a clock having a frequency an integer multiple of the frequency of the basic clock by; By using the output clock of the output signal of the synchronous detection device and a downlink control signal, the PLL device comprises a link control signal generating device for generating an image, by being one to relay a downlink signal accurately and reliably will.
