Abstract
Adjacent base stations transmit and receive a signal using a plurality of carriers (frequencies), for example, f1 through f3. One base station has the largest transmission power for the carrier f1 and the smallest transmission power for the carrier f3. Another base station has the smallest transmission power for the carrier f1 and the largest transmission power for the carrier f3. Each of the carriers f1 through f3 has a different boundary positions.
