摘要
高频技术是5G的关键技术之一,可满足热点高容量场景的需求,因此在5G时代,产业界积极探索如何使用6GHz以上的高频资源。本文介绍了高频信道建模方法的标准化进展、高频信道建模所增加的新特性以及可以克服高频传输衰减问题的模拟波束赋形技术,并通过仿真对比分析了模拟波束赋形所带来的信号增益。
High frequency communication is one of the key technologies of 5 G. It can be applied in high-capacity hotspot Scenario. In 5 G era, the utilization of above 6 GHz frequency resources is widely explored. The standardization process of channel modeling above 6 GHz and additional features were discussed in this paper. To overcome the problem of large transmission loss in high frequency communication, analog beamforming was introduced. Finally, the simulation results of signal gain with analog beamforming was displayed.
