一种基于mMIMO技术的应用落地实践

A practical application based on mMIMO technology

为应对移动通信业务量的迅猛增长,以及对信息传输的速率、时延、可靠性等各方面都提出了更高的要求,大规模多进多出(Massive MIMO,m MIMO)因其空间资源挖掘的独特优势而获得青睐与重视,可实现系统频谱和能量效率的极大化,已成为5G的关键技术之一。文章介绍了m MIMO的关键技术原理,提出了针对不同TR数的设备进行差异性部署的方法,同时介绍了m MIMO最关键的波束赋形技术的优化思路和详细案例,为后续打造低成本优质5G精品网络具有重要意义。

In response to the rapid growth of mobile communications business,as well as to the reliability of information transmission rate,time delay,and so on various aspects are put forward higher request,large-scale enter much more technology,the technology fully mining space resources,increase efficiency of the system frequency and energy efficiency,has become one of the key technology of 5g.This paper introduces the key technology principles of mMIMO,puts forward the method of differential deployment for different TR number of devices,and introduces the optimization idea and detailed case of the most critical beam forming technology of mMIMO,which is of great significance for the subsequent creation of low-cost high-quality 5G high-quality network.
