Proportional fair scheduling apparatus for multi-transmission channel system, method thereof and recording medium for recording program of the same

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.
