partitions each cell into two regions; inner region and outer
region and allocates different frequency band to each region.
Since the users at the inner region are less exposed to inter-cell
interference, the frequency resources in each inner region can be
universally used. Based on this frequency band allocation, FFR
may reduce channel interference and offer large system capacity.
This paper proposes a mechanism that selects the optimal FFR
scheme based on the user throughput and user satisfaction. In
detail, the mechanism selects the optimal size of the inner and
outer region for each cell as well as the optimal frequency
allocation between these regions that either maximizes the mean
user throughput or the user satisfaction. The mechanism is
evaluated through several simulation scenarios.10aFFR10aLTE1 aBouras, Christos1 aPapazois, Andreas1 aKokkinos, Vasileios1 aTseliou, Georgia1 aBilios, Dimitrios  uhttps://telematics.upatras.gr/telematics/publications/optimization-fractional-frequency-reuse-long-term-evolution-networks?language=el
