Abstract
Provided are an apparatus and method for controlling transmit power of a base station and a mobile communication base station using the same, which can control transmission power for minimizing interference from the base station to a cell adjacent thereto. When a power amplifier outputs the minimum value of a power range restricted by a dynamic range in consideration of an offset against a lowest value of an output power, a comparator compares an optimal transmit power of the base station and the minimum value of a power range restricted by the dynamic range, and an attenuator attenuates the output power value of the power amplifier according to the comparison result.
