摘要
高频是移动通信的重要应用方向,也是5G设计的重要方向.3GPP在R15、R16及R17中对于高频都做了相关研究和标准化工作.结合3 GPP国际标准化工作,首先对高频的各种用例、部署场景进行了详细介绍;接着对3 GPP标准化中帧结构设计、接入设计、大规模天线设计和频域配置等关键技术进行了分析;最后对5G高频相关的国际标准化内容进行了总结和展望.
High frequency is an application direction of wireless mobile communication and 5 G. 3 GPP has made lots of research and standardization work for high frequency in R15,R16 and R17. In this paper,based on 3 GPP international standardization development,various use cases and deployment scenarios of high frequency are introduced in detail.Then the key technologies of 3 GPP standardization,such as frame structure design,access design,large-scale antenna design and frequency domain configuration,are analyzed. Finally,this paper summarizes and prospects the contents of5 g high frequency related international standardization.
