Abstract
Proportional fair scheduling (PFS) provides good balance between throughput and fairness via multi-user diversity and game-theoretic equilibrium. Very little analytical work exists on understanding the performance of PFS. Most existing prior results are for networks with Rayleigh fading. In this paper, we provide theoretical results for PFS in general fading environments. The results reveal that the average throughput of a user solely depends on its own channel statistics when its instantaneous data rate is Gaussian. Based on the theoretical results, we analyze the PFS performance under various scenarios with Rayleigh and/or Rician fading, and the numerical results match very well with the simulation ones. To the best of our knowledge, this work is the first one theoretically investigating the PFS problem in general fading environments.
