© 2016 IEEE. Soft Frequency Reuse (Soft FR) is an effective resource allocation technique that can improve the instantaneous received Signal-to-Interference-plus-Noise ratio (SINR) at a typical user and the spectrum efficiency. In this paper, the performance of Soft FR in Random Cellular network, where the locations of Base Stations (BSs) are random variables of Spatial Point Poisson Process (PPP), is investigated. While most of current works considered the network model with either single RB or frequency reuse with factor of 1, this work assume that the Soft FR with factor of Δ is deployed and there are M users and N (Δ > 1, M > 1, N > 1). The analytical and simulation results show that a network system with high frequency reuse factor create more InterCell Interference than that with low frequency reuse factor. Furthermore, in order to design the parameters to optimize Soft FR, the performance of the Cell-Edge and Cell-Center user should be considered together.
