Claim 6:
7. A first base station (BS) for cancelling remote cross-link interference (CLI) between BSs, the first BS comprising:
a transceiver connected to at least one processor; and
the at least one processor, wherein the at least one processor is configured to
detect occurrence of the remote CLI, broadcast a first reference signal (RS) including information related to the first BS, based on detection of occurrence of the remote CLI,
obtain 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
confirm 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.
