In the context of OFDMA-based 4G/5G heterogeneous cellular networks, the deployment of femtocells is a solution to increase the capacity and coverage of indoor areas. This paper presents an analytical framework allowing the downlink performance evaluation of fractional frequency reuse (FFR)-aided OFDMA-based two-tier HetNets where scheduling of both macro(More)
Interference coordination techniques are typically incorporated in OFDMA-based multi-cellular networks in order to preserve high spectral efficiencies over the whole coverage area and to improve the system capacity. Fractional frequency reuse (FFR) and its variants are employed to mitigate the inter-cell interference that particularly suffer cell-edge(More)
Interference coordination techniques are incorporated in OFDMA-based multi-cellular networks allowing near universal frequency reuse while preserving reasonably high spectral efficiencies over the whole coverage area. Two very representative strategies are fractional frequency reuse (FFR) and soft frequency reuse (SFR), which are deemed to play a key role(More)
