Abstract

Vehicle-to-everything (V2X) communications is an important part of future driver assistance and traffic control systems that will reduce accidents and congestion. The millimeter-wave (mmWave) band shows great promise to enable the high-data-rate links that are required or at least beneficial for such systems. To design such systems, we first need a detailed understanding of the vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2X) propagation channels. This paper provides a systematic account of a series of measurement campaigns for such channels, conducted by the four research institutions of the authors over the past year. After a description of the similarities and differences of the channel sounders used in the campaigns, a description of the measurements in two European and one American city is given, and the scenarios of convoy, opposite-lane passing, and overtaking, are described. This is then followed by key results, presenting both sample results of power delay profiles and delay Doppler (or angular) spectra, as well as the statistical description such as delay spread and size of stationarity region. We also discuss the availability of spatial diversity in V2I connections and the correlation of the channels between different frequency bands.
城市环境中的毫米波V2X信道测量
车联网(V2X)通信是未来驾驶辅助和交通控制系统的重要组成部分,将减少事故和拥堵。毫米波(mmWave)频段显示出巨大的希望,可以实现这种系统所需的高数据速率链路,或者至少是有益的。为了设计这样的系统,我们首先需要详细了解车对车(V2V)和车对基础设施(V2X)的传播渠道。本文提供了一系列的测量活动的系统帐户,这些渠道,由作者的四个研究机构在过去一年中进行。在描述了在战役中使用的航道测深仪的异同之后,给出了在两个欧洲城市和一个美国城市的测量描述,并描述了车队,对面车道超车和超车的场景。然后是关键结果,给出了功率延迟曲线和延迟多普勒(或角)谱的样本结果,以及延迟扩展和平稳区域大小等统计描述。我们还讨论了V2I连接中空间分集的可用性以及不同频带之间信道的相关性。
