Classification: CPC H | IPC H

Claim 11:
12. A second base station (BS) for cancelling remote cross-link interference (CLI) between BSs, the second 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
receive a first reference signal (RS) including information related to a first BS about a technique for canceling the remote CLI from the first BS,
confirm 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 reduce power of the downlink signal, at the obtained location of the time-frequency resource based on the technique for canceling the remote CLI, and

transmit 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.
