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

摘要

PURPOSE: A base station transmission output control apparatus is provided to enhance link performance and spectrum efficiency and to reduce the interference of a neighboring cell user by optimizing base station transmission power. CONSTITUTION: A transmission output control unit includes a power amplifier(401), a comparator(402), and an attenuator(403). The power amplifier outputs the minimum value in consideration of offset compared to the lowest limit output value. The comparator compares the minimum value by the dynamic range and a BS(Base Station) transmission output. The attenuator attenuates the output value of the power amplifier according to a result of the comparator.
