摘要
随着5G移动通信系统的快速发展,5G基站和终端在实际外场环境下的吞吐量性能对用户体验至关重要。如何在室内精确建模和复现外场信道环境,成为学术界和产业界的研究热点。介绍了4G和5G的信道建模方法,并针对5G终端设备,阐述了目前实验室多输入多输出(multi-input multi-output,MIMO)空口(overthe-air,OTA)测试解决方案的优势,然后给出了具体的OTA信道建模原理描述以及吞吐量仿真结果,以期为相关工作提供参考。
With the rapid development of 5G wireless communication system,the throughput of 5G gNB and user equipment(UE)in the practical field environment is of great important.How to generate the accurate model in lab,which can represent the propogation condition in the field,has drawn great interests from both the academic and industrial communities.The channel modeling methods of 4G and 5G were introduced,and for 5G UE testing,the advantages of the multi-input multi-output(MIMO)and over-the-air(OTA)performance test solution were showed.Then,a detailed description of the OTA channel modeling principle and throughput simulation results were given in order to provide reference for related work.
