摘要
对移动通信系统更高的速率和容量需求催生了毫米波在移动通信领域的应用。5G移动通信毫米波系统中的关键技术是波束赋形,利用不同的波束赋形权值可以调整小区的覆盖。选择合适的波束权值可以让小区覆盖更合理,从而使系统整体的吞吐量表现更好。介绍了移动通信领域毫米波系统的基本原理,以及如何用机器学习的方法来改进毫米波的波束管理。
For the requirement of faster data rate and more system capacity in the mobile communication system, millimeter-wave is introduced.Beamforming is a key technology in the 5G millimeter-wave mobility system, and different beamforming weightscan change the cell coverage. A suitable beam weight can provide a better cell coverage, and consequently provide better systemthroughout performance. It introduces the basic principle of the millimeter-wave system in the mobile communicationsystem, and how to use the machine learning to improve the beam management in millimeter-wave system.
