The present invention relates to an RF repeater used in a time division method, and a method thereof. An RF repeater according to an exemplary embodiment of the present invention receives a downlink signal that is to be transmitted from a base station to a mobile terminal, performs first automatic gain control on the downlink signal, and extracts gain information from the downlink signal on which the first automatic gain control has been performed, on the basis of gain variation information that is the gain information for the downlink signal. Then, the RF repeater performs second automatic gain control on the downlink signal on the basis of the extracted gain information, and performs a control operation such that the downlink signal on which the second automatic gain control has been performed is transmitted to the mobile terminal. According to the exemplary embodiment of the present invention, the RF repeater maintains the received uplink signal at the predetermined level or more by using a pilot signal of a subcarrier that is not allocated during the downlink period, regardless of the number of mobile terminals that are connected to the RF repeater. As a result, the RF repeater can efficiently perform automatic gain control on the uplink signal without performing separate signal analysis or control.
