Sector-based Radio Resource Management for SC-FDMA cellular systems

In this paper, we study how to improve the performance of an SC-FDMA cellular system by reusing frequency resources on a per-sector basis, in a tri-sectorized multi-cell scenario. We consider a typical cell-based Fractional Frequency Reuse (FFR) scheme as a reference, and we propose two novel sector-based Inter-Cell Interference Coordination (ICIC) schemes. Our simulations show that, in comparison to the cell-based proposals, our novel schemes succeed on increasing the supported traffic load, while guaranteeing the required level of Quality of Service (QoS) for real-time traffic.
