RELAY AND TRANSMISSION BANDWIDTH PARTITION METHOD OF RELAY USING ON-OFF SIGNAL

摘要

PURPOSE: A relay and a transmission band partitioning method of the same using an on-off signal are provided to reduce interference generated by the movement of a relay. CONSTITUTION: A controller(340) determines whether to divide transmission bands by using an on-off signal and first SINR strength value of a relay and a terminal. The on-off signal is received from a first relay which is adjacent to the relay. The entire frequency band is divided into transmission bands in a downlink between the relay and the terminal. The transmission bands are divided into a plurality of sub-bands according to a previously set frequency usage coefficient.
