Abstract
Fractional Frequency Reuse (FFR) has been suggested as an Inter Cell Interference Coordination (ICIC) technique in Orthogonal Frequency Division Multiple Access (OFDMA), where the cell is separated into internal and external regions. The inner means that it is close to eNB, while the outer indicates closeness to the boundaries of the cell. The main idea of FFR is to divide the cell’s bandwidth into partitions for reducing the cell interference from both inner users and the adjacent cells. The FFR has three main types including Strict FFR, Soft FFR and Sectored FFR (SFFR). This work proposes a hybrid Soft Sectored Fractional Frequency Reuse (SSFFR), which analyzes the uplink worst case Signal to Interference power Ratio (SIR). In addition, the effect of power control exponent, path loss exponent and inner radius are studied, and SSFFR is compared with SFFR. Simulation results show that, the higher SIR achieved by outer-SSFFR, enables to enhance the cell edge transmission through interference management.
