One embodiment of the present invention relates to a method for removing interference occurring in a full-duplex access point (AP) that relays an RF signal in a wireless network environment. The objective of the present invention is to eliminate interference occurring in communication between an AP and a client in a Wi-Fi network environment, thereby providing a wireless network protocol capable of obtaining the maximum performance gain in a full-duplex mode. The method includes the steps of: defining a transmission signal generated between the AP and a transmitter (TX) transmitting a signal to the AP and a reception signal generated between the AP and a receiver (RX) receiving the signal from the AP, and removing self-interference in consideration of a channel gain of the self-interference in the AP; defining a channel transmitted to the AP from the TX as an uplink, defining a channel transmitted to the RX from the AP as a downlink and producing a signal to interference noise ratio (SINR) capable of being transmitted in the uplink and the downlink; selecting the RX capable of maximizing total capacity of transmission power in the uplink and the downlink; and selecting the optimal transmission power for the AP and the TX in order to maximize a transmission SINR value in the uplink and the downlink. |
