Wireless communication is now moving to automotive systems. In the near future, vehicles and road side units (RSUs) will be equipped with various sensors such as radars, LIDARs, cameras, and GPSs to generate enormous sensor information. To enhance the safety and efficiency, they will share this raw sensor information each other through Gbps data rates using millimeter-wave (mmWave) communications. To realize this vision, two unfavorable attributes of mmWave communications should be addressed: 1) Overcoming blockage and 2) fast link configuration. One viable approach to addressing these issues is to exploit RSU equipped with many sensors. At a higher position such as at the top of the RSU, LoS links between vehicles and the RSU are more likely to be guaranteed as well as it facilitates the extraction of useful information for the fast link configuration such as the distances or the angles between vehicles and the RSU using the sensors. In this paper, we assume that from the sensors (aside from the relevant technology) the angular support information for the LoS link of each vehicle is known to the RSU in prior and we propose a fast link configuration method using the angular support information.
