FEMTO CELL BASE STATION APPARATUS THAT SENSES PERIPHERAL MACROCELL ENVIRONMENTS, PERFORMS SELF-CONFIGURATION, AND ALLOCATES RESOURCES ACCORDING TO A SITUATION WHEN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS (OFDMA)-BASED CELLULAR MOBILE COMMUNICATION NETWORK IS INSTALLED WITH A FEMTO CELL BASE STATION APPARATUS, AND A SELF-CONFIGURING METHOD THEREOF
FEMTO CELL BASE STATION APPARATUS THAT SENSES PERIPHERAL MACROCELL ENVIRONMENTS, PERFORMS SELF-CONFIGURATION, AND ALLOCATES RESOURCES ACCORDING TO A SITUATION WHEN AN ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS (OFDMA)-BASED CELLULAR MOBILE COMMUNICATION NETWORK IS INSTALLED WITH A FEMTO CELL BASE STATION APPARATUS, AND A SELF-CONFIGURING METHOD THEREOF
PURPOSE: A femto cell base-station apparatus and a self-configuring method thereof are provided to minimize damage to macro cells by performing self-configuration to minimize interference to adjacent macro cells or other femto cells and allowing the femto cells to maximally secure its own area, and a self-configuring method thereof.;CONSTITUTION: A femto cell base station apparatus(1) includes an antenna(100), a wireless signal transmitting/receiving unit(200), a transmitting/receiving separator(300), a receiver(400), a preamble extractor(500), a power allocator(600), a preamble selector(700), a resource allocator(800), a demodulator(900), an inverse frame generator(1000), a decoder(1100), a preamble generator(1200), a modulator(1300), a frame generator(1400), and a transmitter(1500). The wireless signal transmitting/receiving unit transmits/receives signals from femto cells and macro cells through the antenna. The transmitting/receiving separator separates received signals that are applied from the antenna and signals that are transmitted from the transmitter. The receiver receives the signals from the femto cells and the macro cells that are separated by the transmitting/receiving separator. The preamble extractor extracts preambles from the signals from the femto cells and the macro cells that are received by the receiver. They are then separated into signals corresponding to the femto cells and signals corresponding to the macro cells. The signals from the femto cells are transmitted to the demodulator 900 and the signals from the macro cells and the femto cells are transferred to the power allocator. The power allocator allocates the transmission power of the femto cell base station apparatus during an initialization step.;COPYRIGHT KIPO 2010
