摘要

为了应对快速增长的通信量，第五代(5G)移动通信系统提出了分布式大规模MIMO (DM-MIMO)技术。DM-MIMO协调位于超高密度(UHD)的大量分布式传输点(TP)，并为每个TP使用不同数量的天线单元。它可以大幅提高5G的面频谱效率。它还可以动态地创建与用户移动性相对应的以用户为中心的虚拟单元。为了设计适用于5G各种用例的DM-MIMO灵活的天线部署，需要确定一些关键参数，如分布式TP的数量、每个TP的天线单元数量、TP之间的适当距离等。本文针对总发射功率固定、天线单元总数不变、天线部署灵活的5G DM-MIMO进行了这样的讨论。计算机仿真表明，与使用128个天线单元的大规模MIMO系统相比，DM-MIMO可以实现2.5倍以上的系统吞吐量。

Flexible antenna deployment for 5G distributed Massive MIMO in low SHF bands

In order to tackle rapidly increasing traffic, distributed Massive MIMO (DM-MIMO) has been proposed for fifth-generation (5G) mobile communication systems. DM-MIMO coordinates lots of distributed transmission points (TPs) that are located in ultra-high density (UHD) and use various numbers of antenna elements for each TP. It can achieve drastic improvement of areal spectrum efficiency for 5G. It can also dynamically create user-centric virtual cells corresponding to user mobility. To design flexible antenna deployment of DM-MIMO that is applicable to various use cases in 5G, some key parameters such as the number of the distributed TPs, the number of antenna elements for each TP, and proper distance between TPs should be determined. This paper provides such discussion for 5G DM-MIMO with the flexible antenna deployment under fixed total transmission power and constant total number of antenna elements. Computer simulations show that DM-MIMO can achieve more than 2.5 times system throughput in comparison with a Massive MIMO system using 128 antenna elements.
