摘要
近年来,移动通信的数据量迅速增长,其中大部分发生在室内及热点场景。而到目前为止的移动通信技术主要是针对大覆盖的场景,缺乏室内分布系统的研究。因此,LTE室内覆盖优化方案不仅是3GPP标准化进程中的一个重要课题,也是国际运营商在网络优化中的重要考量。首先介绍了LTE-Hi系统的技术特征,然后比较其他常用室内覆盖方案,分析了该系统的优势,最后介绍了LTE-Hi技术的发展方向。
Data volume of mobile telecommunica- tion is increasing rapidly in recent years, most of which happen in hotspot and indoor scenario, al- though most of mobile telecommunication technolo- gies are designed for macro cell scenario. Thus, op- timization proposal for LTE indoor scenario is not only an important issue in 3GPP standardization process, but also an important factor for mobile communication network optimization. In this paper, we firstly introduce key technical characteristics of LTE-Hi system. Then, compared with other indoor distribution systems, we analyze advantages of LTE- Hi system. Finally, we introduce evolution route of LTE-Hi system.
