A novel dynamic inter-cell interference coordination technique for LTE networks

—Inter-cell interference problems arise in dense frequency reuse networks such as Long Term Evolution (LTE). They have harmful impact on system performance, especially for cell-edge users or users having bad radio conditions. Inter-Cell Interference Coordination (ICIC) schemes aim at mitigating the interference produced by nearby cells to enhance the performance of cell-edge users. ICIC techniques include static frequency reuse schemes and cellcoordinated schemes. In this paper, we propose a semistatic frequency allocation algorithm that exploits evolvedNodeBs communications via X2 interface to mitigate intercell interference. Each cell is divided into two zones: cellcenter and cell-edge. Cell zone satisfaction is tracked, and the unsatisfied zone gets more frequency resource blocks in a distributed manner. The scope of this work is on the downlink of LTE networks using frequency division duplex transmission mode. An LTE downlink system level simulator is chosen to compare the perfo...
