V2X communication in the mmWave band is one way to achieve high data rates for applications like infotainment, cooperative perception, augmented reality assisted driving, and so on. MmWave communication relies on large antenna arrays, and configuring these arrays poses high training overhead. In this article, we motivate the use of infrastructure mounted sensors (which will be part of future smart cities) to aid establishing and maintaining mmWave vehicular communication links. We provide numerical and measurement results to demonstrate that information from these infrastructure sensors reduces the mmWave array configuration overhead. Finally, we outline future research directions to help materialize the use of infrastructure sensors for mmWave communication.

在毫米波通信基础设施中利用传感

毫米波频段中的 V2X 通信是为信息娱乐、协作感知、增强现实辅助驾驶等应用实现高数据速率的一种方式。毫米波通信依赖于大型天线阵列，配置这些阵列会带来很高的训练开销。在本文中，我们鼓励使用安装在基础设施上的传感器（这将成为未来智慧城市的一部分）来帮助建立和维护毫米波车载通信链路。我们提供数值和测量结果来证明来自这些基础设施传感器的信息减少了毫米波阵列配置开销。最后，我们概述了未来的研究方向，以帮助实现毫米波通信基础设施传感器的使用。
