摘要： A proportional fair scheduling apparatus for a multi-transmission channel system, a method thereof and a recording medium for recording program of the same. When each user reports an available transmission rate of a current slot according to transmission channels in the multiple transmission channel system, the scheduling apparatus calculates an average transmission rate of previous slots, and calculates scheduling priority values for all allocation schemes of allocating each transmission channel to users according to transmission channels based on information about the transmission rates. The scheduling apparatus determines an allocation scheme having the maximum priority value from among the calculated priority values, and allocates the transmission channels to the users according to the result of the determination. Therefore, the proportional fair scheduling scheme is applied to the multiple transmission channel system, and the users can transmit signals in an optimum channel environment.

摘要： An apparatus and method for allocating a channel using an auction algorithm in a wireless communication system. The method includes measuring a data rate of each channel; selecting one of the channels, when information on the channels is received from a base station, using the received information on the channels and the measured data rate; and determining a bidding price of the selected channel. Performance of the entire system can be improved by reducing complexity as well as guaranteeing an optimal value in the channel allocation.

摘要： A scheduling method and system is disclosed that divides scheduling between a base station and a mobile station into scheduling between the base station and a relay station and scheduling between the relay station and the mobile station, and performs the divided schedulings. In a radio communication system that transmits a signal of a base station to mobile stations located on a border of a cell by using a relay station, the base station having multiple antennas receives phase information of the respective antennas from the relay station having multiple antennas, compensates for phases of the respective antennas, and transmits data through the phase-compensated antennas. The relay station transmits only channel quality information of the mobile station, which has a high possibility of being selected by the base station among channel quality information of the mobile stations that belong to the relay station, to the base station.
