METHOD FOR CONTROLLING THE TRANSMISSION POWER OF A FEMTO BASE STATION AND A DEVICE THEREOF CAPABLE OF USING SIGNALING BETWEEN BASE STATIONS

摘要

PURPOSE: A method for controlling the transmission power of a femto base station and a device thereof are provided to calculate the size of interference received from adjacent femto or macro base stations using a femto terminal.;CONSTITUTION: An interference predicting part(620) predicts femto base station interference which is applied from an adjacent femto base station to a terminal and macro base station interference which is applied from a macro base station to the terminal. A power controlling part(640) determines the transmission power of downlink signals based on the femto and macro base station interference. A transmitting part(650) transmits the downlink signals based on the transmission power. The interference from the femto base station is predicted based on a distance between a serving femto base station and the adjacent femto base station and the transmission power of the adjacent femto base station. The interference from the macro base station is predicted based on a distance between a serving femto base station and the macro base station and the transmission power of the macro base station.;COPYRIGHT KIPO 2012
