Abstract: PURPOSE: A distributed resource allocation method in multi-femto cell environment and apparatus thereof are provided to solve hided node problems by controlling interference between multi-femto cells in a wireless communication system. CONSTITUTION: An average reception power measuring unit(703) measures average reception power for reception signals. The average power measurement unit transmits the measured average reception power to an interference permission information determination unit(704). The average reception power measurement unit transmits the measured average reception power to a preference sub-channel selecting unit(702). An interference permission information determination unit determines interference permission information. The preference sub-channel selecting unit determines a preference band group based on the measured SNR(Signal to Noise Ratio).

Abstract: PURPOSE: A cooperation transmission method and an apparatus thereof are provided to perform user scheduling of a multiple antenna wireless system in order to obtain a multiple user diversity gain. CONSTITUTION: An apparatus determines a user group having channel correlation characteristics by using quantized channel correlation information(203). The apparatus selects a user according to the channel quality of group users(204). The apparatus transmits a signal by using a transmission beamforming method(205,206).
