Downlink performance of cellular networks is mainly limited by Intercell Interference (ICI). A promising concept for ICI mitigation is Fractional Frequency Reuse (FFR), which effectively allows to trade off overall performance against enhanced cell-edge performance. In this work, a novel FFR scheme is proposed. It assigns a given user to a frequency sub band depending on the achievable capacity density (bit/s/m²). An optimization problem is formulated, which aims at maximizing average per-user throughput while maintaining a minimum performance at cell-edge. Simulations are carried out for omnidirectional and sectorized cellular scenarios, using both 2-dimensional and 3-dimensional antenna radiation patterns. The simulation results show that the proposed scheme outperforms conventional reuse-1- and reuse-3 schemes in terms of average- and cell-edge performance.

Martin Taranetz was born in April 1986 in Amstetten. He received his BSc. in Electrical Engineering in 2008 and his Dipl.-Ing. in Telecommunications in 2011, both at the UT Vienna. Currently he is studying towards his PhD degree and working as university assistant at the Insitute of Telecommunications in the field of system level research.
