Reutilización Fraccional de Frecuencia con Sectorización sobre Redes Celulares

Abstract

In this paper, we investigate the downlink of homogeneous LTE cellular networks with Fractional Frequency Reuse (FFR) and sectorized antennas where non-ideal radiation patterns have been considered. Three frequency allocation schemes are proposed: i) static; ii) dynamic and iii) proportional, that differ in complexity and performance. Such schemes are compared in terms of aggregate (per cell) capacity and fairness for the case of 3 and 6 sectors. Results reveal that proportional allocation achieves a good balance between aggregate capacity and fairness, while dynamic allocation achieves the highest capacity with a small fairness. Finally, it is observed that 6-sectors configuration leads to a higher capacity and fairness.
