摘要
高频通信是5G的关键技术之一,利用大带宽传输可以成倍提升系统容量,可应用在热点高容量的技术场景,对于下一代移动蜂窝网来说,高频具有重要的意义。因此,在5G时代,产业界积极探索使用6 GHz以上的高频资源,高频通信技术是5G无线空口不可或缺的关键技术。主要介绍了现有高频段的频谱现状,高频段产业界的射频器件和射频指标现状以及高频信道建模。
High-frequency communication is one of the key technologies of 5G. it can multiply the capacity of the system by utilizing large bandwidth transmission. It can be applied in high-capacity hotspot technology scene. High-frequency communication is with great significance to the next generation mobile cellular network. In the 5G era, the utilization of above 6 GHz high-fre- quency resources is widely explored. The high-frequency communication technology is one of the essential to 5G wireless air interface key technologies. The current status of high-frequency spectrum, high-frequency industry RF devices and RF status and high-frequency channel modeling are introduced.
