APPARATUS AND METHOD FOR AVOIDING INTERFERENCE BETWEEN BASE STATION AND RELAY STATION WHEN USING FULL DUFLEX RELAY IN MULTI HOP RELAY SYSTEM

摘要

An apparatus and a method for avoiding interference between a base station and a relay station when using full duplex relay in a multi hop relay system are provided to minimize cell interference between the base station and the relay station about a terminal by using a full duplex relay method. A signal meter measures intensity of a received signal from a base station and a relay station. An interference decision device calculates a ratio of intensity of received signals from the base station and the relay station. The interference decision device(413) determines whether interference exists by using the ratio of the intensity of the received signals. A message generator produces a control message showing whether the interference exists.
