Executive Summary

Inter-Cell Interference Coordination (ICIC) is one of the key technologies in the multi-cell radio resource management of mobile systems. ICIC must be effectively used to reduce the mutual interference of edge users in Heterogeneous network (Het-net), where the interference scenario becomes more complicated. ICIC plays a significant role in improving cell edge spectrum efficiency. In this paper, the limitation of traditional ICIC method is analyzed and a novel ICIC method based on User' position is proposed for the improvement of the downlink ICIC efficiency. By the system simulation, it is approved that the edge user throughput and system average throughput may be improved in different degree respectively.
