1. An operation method of a repeater performing relaying between a base station and a first terminal in a communication system, the operation method comprising:
receiving one or more signals from at least one of the base station and the first terminal;
performing monitoring on the one or more signals in a time interval for which a transmission direction is not determined by the base station; and
determining the transmission direction of the time interval based on a result of the monitoring,
wherein the one or more signals include at least one of a first signal received from the base station or a second signal received from the first terminal,
wherein the operation method further comprises retransmitting the first signal to the first terminal when the result of the monitoring indicates that the first signal is detected only by a first antenna included in the repeater, and retransmitting the second signal to the base station when the result of the monitoring indicates that the second signal is detected only by a second antenna included in the repeater, and
wherein the first antenna is an antenna wirelessly connected to the base station, and the second antenna is an antenna wirelessly connected to the first terminal.
