摘　　要：5G是我国新型基础设施建设的重点领域,毫米波和大规模MIMO是5G的关键技术之一。对于射频与天线一体化集成的毫米波有源天线单元(Active Antenna Unit,AAU),传统的传导测试方法已不再适用,空口测试(Over-The-Air,OTA)将成为首选的测试形态。这是移动通信发展近三十多年以来测试原理的一次革新。近年来,学术界和产业界针对5G毫米波OTA测试的若干关键问题开展了大量探索性研究,已在多个技术领域取得突破,但分歧依然较大,至今尚未形成系统化和标准化的测试规范。本文将从射频测试和性能测试两个方面,梳理分析5G毫米波OTA测试方法的研究进展。The 5th generation(5G)wireless communication is one of the important parts of the new form of infrastructure construction in China,and millimeter wave(mmWave)and massive MIMO are two key technologies of the 5G mobile wireless communications.It is impractical to perform conventional conduct testing anymore in testing the mmWave Active Antenna Unit(AAU)and the Antenna-in-Package(AiP)equipment,for their antennas and radio frequency(RF)modules are highly integrated.As a result,OverThe-Air(OTA)test will be the prior choice,which represents a milestone in testing field of the wireless communications over the past three decades.Recently,academia and industry have addressed several key issues of the 5G mmWave OTA test,but a systematic and standardized test specification has not been officially approved yet.This paper reviewed the research and progress in 5G millimeter wave testing from two aspects:the RF index testing and the systematic parameter testing.
