针对LTE R8中ICIC技术应用问题，业界提出了AICIC技术。本文阐述了AICIC的原理与实现架构，并通过单小区的定点与移动场景测试，验证AICIC技术在不损害小区整体吞吐量性能条件下，能够较大提高小区边缘的性能增益。同时对基站到集中控制器的时延进行了现网测试分析，结果表明该时延水平完全可以满足AICIC策略制定需求。

AICIC technology has been proposed to deal with the limitation of application of ICIC technology. In this article, the principle and architecture of AICIC is described. Through the single cell test of fixed and mobile scene, it is verified that AICIC technology can considerably improve the cell-edge performance without reducing the overall throughput of the cell. Besides, the delay from eNode B to e-coordinator is tested and analyzed in existing network, and the result shows that delay can completely meet the needs of AICIC strategy.
