A unified analysis of CDF-based distributed scheduling in a heterogeneous multicell

This paper analyzes the performance of distributed scheduling policies in a generic heterogeneous multicell downlink. Our focus is on the utilization of the cumulative distribution function (CDF)-based scheduling policy to guarantee scheduling fairness and simultaneously obtain multiuser diversity gain. Under the standard Rayleigh fading assumption on both the desired signal and the intercell interference, we derive the CDF of the selected user's signal-to-interference-plus-noise ratio (SINR), and utilize the obtained CDF to develop a unified analysis of average system performance utilizing a general performance measure. The closed form results are specialized to three performance metrics: rate, probability of error, and moment of the SINR. The corresponding results for the round robin policy and the greedy policy are also provided for comparison and completeness.
