Abstract

The Fractional Frequency Reuse (FFR) scheme combines the benefits of universal Frequency Reuse and Frequency Reuse Factor (FRF)3. Universal Frequency Reuse scheme has high spectral efficiency while FRF=3 scheme is normally used to mitigate Intercell Interference (ICI) in a cellular system. Nevertheless, the advancement of the wireless technology does not stop here. The trend of Long Term Evolution-Advanced (LTE-A) is still looking forward to further penetration in better coverage, higher capacity and higher spectrum efficiency. Femtocell is a promising option in terms of cost-effectiveness, coverage and capacity improvement in hybrid network. Furthermore, the physical size of Femtocell allows it to be deployed at Died zone" and improve the cell-edge user performance. This paper evaluates the performance of hybrid network with three different networks, universal FRF, FFR scheme and FFR with Femtocell power control scheme. The performance is evaluated base on SINR experienced by Macrocell users and Femtocell users. The ultimate goal of the research is to analyze the performance of hybrid network and further reduce the impact of the interference generated by Femtocells. The result shows that both FFR and power control schemes improve the SINR of cell edge Macrocell user.
