PFS: Proportional Fair Scheduling
Proportional Fair Scheduling (PFS) is a scheme for wireless communication for both a single antenna system and multiple transmit and receive antennas. The Proportional Fair algorithm is an algorithm that schedules the channel for the station that has the maximum of the priority function, where T denotes the data rate potentially achievable for the station at the present moment (in the present time slot), R is the average data rate of this station. Parameters α and β tune the fairness of the scheduler, that is, is it fair to all stations giving them equal bandwidth or is the scheduler maximizing the throughput of the channel.
