摘　　要：与传统宏蜂窝网络架构相比,异构网络架构可以增加系统吞吐量,提高频谱效率,在4G/B4G(FourthGeneration/Beyond Fourth Generation)系统中提供泛在的用户体验。严重影响小区边缘用户吞吐量的小区间干扰是成功部署异构网络需要解决的难点。增强的小区间干扰协调技术可以分为3类:智能功率控制、跨层设计和协作多点传输。本文对各种技术的优缺点、性能、复杂度和存在的问题进行研究,指出了各种技术所面临的挑战和未来的发展方向。Compared with the traditional macro cellular network architecture, the heterogeneous network archi- tecture can increase system throughput, improve spectrum efficiency and provide ubiquitous user experience in 4G/B4G （fourth generation/beyond fourth generation） systems. Because of negative impacts on cell-edge user throughput, inter-cell interference is one of the main challenges to deploy heterogeneous networks successful- ly. Enhanced inter-cell interference coordination technology can be categorized into smart power control, cross- layer design and CoMP （coordinated multipoint transmission）. Strengths, weaknesses, performance, complexi- ty, and problems of different types of technology were investigated thoroughly. In addition, challenges of each type of technology and direction of future technology were provided.
