随着移动通信数据业务流量迅速增长，通过部署微型小区组建异构网络正逐渐成为解决这一问题的演进方向。文章介绍了一种异构网络结构小基站增强（SCE），及其在3GPP中的标准化进程，以及现有的干扰协调技术，分析了这些方案在SCE场景下的应用和存在的局限性，最后针对未来的研究方向提出了建议。

With the data traffic of mobile communi-cation increasing rapidly in recent years, heteroge-neous network with the deployment of small cells has become an important evolution direction. In this paper, we first introduce a heterogeneous network, Small cell Enhancement, and its standardization in 3GPP. Then the existing interference coordination mechanisms in SCE scenario are discussed and the limitation is analyzed. Finally, we give some sugges-tions on further study.
