Radio resource strategies for uplink inter-cell interference fluctuation reduction in SC-FDMA cellular systems

In this paper we propose three different frequency resource management strategies that, working together with FFR and open-loop Fractional Power Control (PFC), succeed on mitigating both uplink inter-cell interference (ICI) and ICI fluctuations, that usually reduce the performance of SC-FDMA cell-based systems. Simulations are carried out with real-time traffic patterns at different loading scenarios, showing that our strategies outperform a typical FFR scheme suggested to coordinate frequency assignments among neighboring cells.
