APPARATUS AND METHOD FOR CONTROLLING CELL TRANSMIT POWER TO REDUCE INTERFERENCE OF CELL AND MOBILE TELECOMMUNICATION BASE STATION FOR THE SAME

摘要

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.
