Abstract

eICIC introduces ABS to reduce inter-cell interference in heterogeneous networks. However, excessive ABS can impair macrocell user performance. In order to improve the performance of heterogeneous networks, this paper proposed an interference coordination scheme based on HPS considering both ABS and LP-ABS. The scheme took into account the resource allocation, HPS density, HPS mixing ratio and user access strategy, in order to maximize the fairness of system proportion as the goal. Simulation results show that the proposed scheme is superior to the traditional enhanced inter-cell interference coordination schemes in terms of system load balancing, user throughput and user fairness.
