Abstract

Third generation partnership project has developed Long Term Evolution - Advanced (LTE-A) technology to enhance the system capacity. Further, frequency reuse concept has been adopted in order to meet the requirement of mobile data traffic. This creates Inter-Cell Interference (ICI) which limits the throughput of cell edge users in LTE - A network. To mitigate ICI, Region splitting based Resource Partitioning with reuse scheme (RRPR) is proposed in this research. The objective is to maximize the sum throughput and average throughput of macrocell. In the proposed RRPR scheme, the whole macrocell is divided into inner, centre and outer regions. The overlaid femtocell partially reuses the spectrum of macrocell. In a cluster of three cells, the total spectrum is partitioned into four non-overlapping sub bands. The outer region of macrocells is assigned with first three sub bands. The remaining one sub band is shared by with the corresponding centre region. The inner region reuses the sub band of outer region of two neighboring cells. The analysis is made with respect to sum throughput and average throughput. The radius of inner and centre region of macrocell is varied using Monte Carlo simulation process. The radius that results with maximum sum throughput is concluded as optimal region radii. The performance metrics of the proposed RRPR scheme is compared with region splitting based resource partitioning scheme. From the simulation result, the inference drawn is that, the maximum of 147.99% enhancement is achieved for both sum throughput and average throughput by the proposed RRPR scheme.
