Abstract:
In this paper we focus our studies on LTE, which is a development under 3G technologies Release-8 of the
3GPP Project plan and is considered a baseline and step towards the LTE-Advanced. 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 queuing 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, 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.
