摘要
毫米波具有较大的路径传播损耗,需要利用定向波束赋形技术来弥补路径损耗。有效的波束管理对于提升毫米波系统性能至关重要。首先介绍了毫米波的频谱特性、优缺点,之后详细介绍了毫米波中的波束赋形和波束管理方案,给出了毫米波波束相关测试数据,为毫米波的应用和部署提供了参考。
Millimeter wave has a large path propagation loss,so it is necessary to use directional beamforming technology to make up for the path loss. Effective beam management is very important to improve the performance of millimeter mobile communication systems. It first introduces the millimeter spectrum characteristics,advantages and disadvantages. Then the beamforming and beam management schemes of MMW are described in detail. Finally,it gives the beam-related test results of MillimeterWave,which provides references for the application and deployment of MMW.
