- In order to mitigate inter-cell interference in 3G evolution systems, A novel inter-cell interference coordination scheme called soft fractional frequency reuse is proposed in this paper, which enables to improve the data rate in cell-edge. On this basis, an inter-cell power control is presented for the inter-cell interference coordination, and the inter-cell balanced SINR among users is established for power allocation, which enables to mitigate inter-cell interference. Especially, the power control is based on a novel exponential kernel equation with faster convergence speed than the traditional arithmetic kernel equations. Numerical results show that the proposed scheme improves the throughput and reduces the blocking rate when compared to the existing power control algorithms.
