摘要

5G 新空口（NR）技术集合三大应用场景，打破了空口传输的限制，为信息科学的突破奠定了坚实的基础。在5G网络的实施部署过程中，基于大规模天线的基站（massive MIMO based base station，MMBS）成了5G关键技术的重要支点。为了确定6 GHz以下频段的MMBS性能，首先介绍了MMBS中的物理层关键技术，给出了MMBS物理层峰值性能和衰落信道环境下性能的主要评估方法，为后续MMBS产品的测试提供了参考指标。在此基础上，分析了当前主流的MMBS性能测试方法，并提出了一套适合当前商业版本的MMBS的性能测试方案。该方案可对基站的5G技术功能和性能进行测试。截至2019年年底，已有多家5G MMBS厂商进行了该项测试。

Abstract

The new radio (NR) of 5G has gathered three main application scenarios and has broken the restrict of the air interface transmission

laying a solid foundation of the information science.Massive MIMO based base station (MMBS) has become the important fulcrum in the implementation deployment of 5G networks.In order to determine performance of the MMBS in sub 6 GHz band

the physical (PHY) layer techniques were firstly introduced

then

for providing a benchmark of the MMBS products

the evaluation method for upbound of the PHY performance and the PHY performance under the fast fading channel environment was given.Based on that

the current mainstream MMBS performance testing methods were analyzed

and a performance testing scheme was proposed which had been suitable for current commercial version of the MMBS.The proposed scheme can be used to test the function and performance of the products with 5G technique.By the end of 2019

there are many manufacturers of MMBS products have been tested by this solution.
