摘要：

In LTE/LTE-A networks, femtocells are used to improve service coverage in indoor environments. Cognitive radio allows femtocell users to share the available spectrum with primary macrocell users. However, some issues arise because of the coexistence between femtocells and macrocells. These issues include but not limited to mitigating interference and fair distribution of network resources. In this paper, we use NSGA II to solve a multi-objective optimization problem that maximizes resource utilization while minimizing interference and guaranteeing fairness among users in a femtocell LTE/LTE-A network. Simulation results show that the proposed scheme improves the multi-objective function score by 8% and enhances the overall performance of the network.
