METHOD AND DEVICE FOR REMOVING SELF-INTERFERENCE IN WIRELESS ACCESS SYSTEM SUPPORTING FULL DUPLEX RADIO SCHEME

摘要

The present invention provides a method for removing a self-interference in a wireless access system supporting a full duplex radio (FDR) scheme, and devices for supporting the same. A method by which a transmission end removes self-interference in a wireless access system supporting an FDR scheme, according to one embodiment of the present invention, can comprise the steps of: transmitting two transmission signals by using two transmission antennas; receiving two reception signals by using two reception antennas; estimating a self-interference channel; and removing interference signals by considering the self-interference channel estimated from the reception signals. Here, the interference signals are the transmission signals which are inputted to the two reception antennas, the transmission signals and the reception signals are simultaneously transmitted and received through a resource region comprising the same time and frequency, and the two transmission antennas and the two reception antennas can be disposed on the transmission end in a diamond shape.

1. A method of cancelling self-interference by a transmitting end in a wireless access system supporting a full duplex radio (FDR) scheme, the method comprising:
transmitting two transmission signals using two transmission antennas; receiving two reception signals using two reception antennas; estimating a self-interference channel; and cancelling interference signals in consideration of the self-interference channel estimated from the reception signals, wherein the interference signals correspond to the transmission signals which are inputted to the two reception antennas, wherein the transmission signals and the reception signals are simultaneously transmitted and received through a resource region configured with the same time and frequency, and wherein the two transmission antennas and the two reception antennas are arranged at the transmitting end in a diamond shape.
