A Long Term Evolution (LTE) technology is the most possible candidate for next generation mobile wireless communications. One impairment of LTE is an interference from neighboring cells, so called Inter-Cell Interference (ICI). A Fractional Frequency Reuse (FFR) has been proposed to handle the problem. Also lately, soft FFR technique has been introduced for better utilization of frequency spectrum. In addition, beamforming technique is considered to be the solution to improve the performance of wireless communication systems.
