Abstract
A method for estimating a self-interference channel by a communication device which operates in a full-duplex mode can comprise the steps of: transmitting a reference signal in a first transmission unit by means of resource elements (REs) of which the number is smaller than the number of antennas of a communication device; estimating a self-interference channel by using a first reference signal matrix, which is returned by means of a self-interference channel in the first transmission unit, and reference signal matrices which are returned by means of a self-interference channel in a predetermined number of transmission units prior to the first transmission unit; and storing information about the estimated self-interference channel.
