Contention-based fractional frequency reuse scheme in LTE/LTE-A network

In order to handle the low efficiency problem caused by an extremely uneven distribution of users for LTE/LTE-A network, we propose a contention based Fractional Frequency reuse scheme. Simulation results show that the proposed scheme not only greatly improves the performance of the edge users but also improve the throughput of the whole network. This method demonstrates potential for applicability to some specific scenarios.
