Statistical Intercell Interference Modeling for Capacity-Coverage Tradeoff Analysis in Downlink Cellular Networks

摘要

Interference shapes the interplay between capacity and coverage in cellularnetworks. However, interference is non-deterministic and depends on varioussystem and channel parameters including user scheduling, frequency reuse, andfading variations. We present an analytical approach for modeling thedistribution of intercell interference in the downlink of cellular networks asa function of generic fading channel models and various scheduling schemes. Wedemonstrate the usefulness of the derived expressions in calculatinglocation-based and average-based data rates in addition to capturing practicaltradeoffs between cell capacity and coverage in downlink cellular networks.
