This letter deals with the problem of beampointing in millimeter-wave (mmWave) vehicle-to-vehicle (V2V) communications. We analyze the impact of the road roughness and the antenna position (rooftop or bumper) by evaluating the beamforming loss with respect to an ideal system. We propose an analytical framework which integrates the model of road profile, its damping through the vehicle suspensions and the transfer to the antenna dynamics. We consider the use of a sensor-assisted and cooperative V2V beam tracking methodology at the two vehicles. Results highlight the advantages of the sensor assisted beam tracking and suggest the usage of rooftop-mounted antennas.

道路粗糙度和天线位置对车载通信的影响



这封信涉及毫米波 (mmWave) 车对车 (V2V) 通信中的波束指向问题。我们通过评估理想系统的波束成形损耗来分析道路粗糙度和天线位置(屋顶或保险杠)的影响。我们提出了一个分析框架,该框架集成了道路轮廓模型、车辆悬架的阻尼以及向天线动力学的传递。我们考虑在两辆车上使用传感器辅助和协作的 V2V 光束跟踪方法。结果突出了传感器辅助波束跟踪的优势,并建议使用屋顶安装的天线。
