Fractional Reuse Partitioning Schemes for Overlay Cellular Architectures

In this paper, the authors propose three partitioning schemes for adaptive clustering with fractional frequency reuse namely maximal fractional frequency reuse partitioning (MFRP), optimal fractional reuse partitioning (OFRP), and GoS-oriented frequency reuse partitioning. The authors propose that an overlaid cellular clustering scheme, which uses adaptive fractional frequency reuse factors, would provide a better capacity by exploiting the high level of signal to interference ratio (SIR). The proposed methods are studied via simulations and the results show that the adaptive clustering with different partitioning methods provide better capacity and grade of service (GoS) comparing to the conventional cellular architectures.
