Claim 5:
6. A method of canceling remote cross-link interference (CLI) between base stations (BSs) by a second BS, the method comprising:
receiving a first reference signal (RS) including information related to a first BS;
confirming that the remote CLI has occurred at the first BS by downlink transmission of the second BS, based on the first RS by calculating a distance between the first BS and the second BS based on the information related to the first BS, obtaining a location of a time-frequency resource of a downlink signal of the second BS at which the remote CLI affects an uplink signal of the first BS, based on the distance between the first BS and the second BS, and skipping transmission of the downlink signal of the second BS or reducing power of the downlink signal, at the obtained location of the time-frequency resource based on the technique for canceling the remote CLI; and
transmitting information related to the second BS to the first BS by broadcasting a second RS or directly notifying the first BS that the remote CLI is caused by the first RS via backhaul signaling.
