Abstract
Small cell enhancement has been considered as a promising way to cope with the rapid growth of need for mobile data traffic. However,it also leads to severe inter-cell interference( ICI) . Traditional frac-tional frequency reuse( FFR) can not be entirely applied to small cell scenario with irregular deployment and a reasonable and efficient method for modeling the network with frequency reuse is needed to evaluate its performance. This paper uses stochastic geometry theory to model small cell network considering FFR and derives the expressions of coverage probability and throughput of small cell network considering FFR. The simulation results show that the FFR can improve the downlink coverage probability of small cell net-works but will decrease the throughput of small cell networks. Finally,it obtains the expression of optimal frequency reuse factor maximizing the throughput under some constrains of coverage probability. These re-sults have important guiding significance for the implementation of small cell networks in the future.关键词
