摘　　要：随着室内4G数据业务爆发式增长,室内分布系统深度覆盖逐步成为运营商网络建设的重点。MIMO作为LTE制式高速通信的关键技术,其在室分场景中的应用效果将直接影响用户体验。首先介绍了MIMO基本原理和优势,并分析了影响MIMO性能的关键因素;然后针对传统和新型LTE MIMO室分建设方案,从网络性能和建设成本方面进行了深入分析;最后结合各方案的特点,提出适合不同场景的建设策略。With the explosive growth of 4G data traffic, the deep coverage of indoor distribution system is becoming the focus of network construction for operators. As MIMO is the key technique of LTE high-speed communication, its application effect in indoor distribution will directly influence user experience. Firstly, the principle and advantages of MIMO are presented in this paper. Secondly, key factors affecting MIMO performance are analyzed. Then, traditional and new LTE MIMO indoor distribution construction schemes are analyzed from the aspects of network performance and construction cost. Finally, according to features of different schemes, construction strategies suitable for different scenes are put forward.
