摘要： A scheduling method in a wireless communication includes receiving a Channel Quality Indicator (CQI) from a plurality of terminals. The method also includes determining an average transmission rate of each terminal based on the CQI by approximating an instantaneous transmission rate distribution to a Gaussian distribution. The method further includes determining a weight of each terminal such that the average transmission rate of each terminal satisfies a target transmission rate. The method also includes selecting a terminal set by applying the determined weight. Thus, it is possible to control the fairness between the terminals and to efficiently control the transmission rate of the terminals according to the required transmission rate and the channel environment of the terminals.
