Abstract :
In orthogonal frequency division multiplexing networks, inter-cell interference results in poor performance, especially universal frequency reuse scheme has already been used. Soft Frequency Reuse (SFR) scheme, one of the most promising inter-cell interference coordination (ICIC) schemes, has been introduced in LTE-Advanced networks. In this paper, We develop an analytical queueing model for the SFR scheme taking into account the features of SFR scheme and its impact on system performance firstly. Then, we improve the iterative algorithm called successive over-relaxation (SOR) to solve the set of linear equations and get the steady state probability distribution. Finally, simulation and performance analysis shows that maximum number of resource that cell-edge users can use and the number of cell-edge users correlate with the performance of SFR scheme.
