A Fairness Scheduling Algorithm for Multiuser MIMO Downlink System

The problem of multiuser fairness in multiuser MIMO system is addressed.We select users according to the channel conditioning,and then count the selection number.If the absolute difference between any numbers is larger than a given threshold,the user with the smaller number will be chosen.The fairness scheduling algorithm makes a good compromise between the multiuser diversity gain and fairness.Simulation results show that the proposed scheduling algorithm improves fairness without much loss in system performance.
