| Summary: | Deploying femtocell overlays over LTE-A macrocellular networks is an effective way to overcome the scarcity of
bandwidth, increase the network coverage, enhance the indoor
users’ performance, and improve the quality of service. Nevertheless, it will bring the cross-tier interference issue to prominence
leading to dramatic degradation of these networks’ performance
if no strategy is taken to tackle this problem. Using the Fractional
Frequency Reuse (FFR) concept can be one of the good solutions
to manage this interference. This paper proposes an FFR scheme
for LTE-A femtocell networks to handle the downlink crosstier interference, generated between macro-cells and femtocells,
in order to increase the Signal-to-Interference and Noise Ratio
(SINR) and improve the overall network performance. The
simulation results obtained by MATLAB reveal the superiority of
the proposed-FFR scheme over the non-FFR one; as both SINR
and user throughput have been enhanced. Outage probability
results also prove that the proposed scheme can effectively
support more users. |
