Theoretical Capacity and Outage Rate of OFDMA Cellular System with Fractional Frequency Reuse

Employing fractional frequency reuse (FFR) in OFDMA cellular systems is attracting a lot of attention since it offers large capacity and one-cell frequency reuse. However its performance under practical environments has not been revealed. This paper analyzes the theoretical capacity and outage rate of an OFDMA cellular system employing FFR. Numerical examples show that FFR achieves higher capacity than the non-FFR equivalent when the outage rate is low.
