1. A method for estimating a self-interference channel by a base station operating a plurality of sectors, the method comprising:
transmitting, in a self-interference channel estimation interval, a downlink signal in a sector among the plurality of sectors;
estimating an intra-sector self-interference channel caused by the downlink signal in the sector;
transmitting, in the self-interference channel estimation interval, a downlink signal in a neighboring sector adjacent to the sector among the plurality of sectors; and
estimating an inter-sector self-interference channel caused by the downlink signal in the neighboring sector in the base station.
