<p>A booster is provided which controls its gain to reduce the adverse effect of the booster noise on a base station. It receives a perch signal transmitted from a base station (180, 182 or the like); measures received power of the perch signal at the booster (100); receives information about the transmission power of the perch signal from the base station (180, 182 or the like); and measures the noise power of the amplified uplink signal at the booster (100). It controls the gain of the uplink signal and/or the gain of the downlink signal in response to the transmission power of the perch signal of the base station (180, 182 or the like), the received power of the perch signal at the booster (100), and the noise power of the amplified uplink signal at the booster (100).</p> |
