1. A method of cancelling remote cross-link interference (CLI) between base stations (BSs) by a first BS, the method comprising:
detecting occurrence of the remote CLI;
broadcasting a first reference signal (RS) including information related to the first BS, based on detection of occurrence of the remote CLI;
obtaining information related to a second BS from the second BS by determining whether the remote CLI affecting the second BS is generated thereby, based on a distance between the first BS and the second BS and a timing according to a propagation delay effect of the remote CLI; and
confirming that the remote CLI has been generated by the second BS, based on the information related to the second BS by broadcasting a second RS or directly notifying the second BS that the remote CLI is caused by the first RS via backhaul signaling.
