论文摘要
提出了实时软件控制的可重新配置智能表面（RIS）单元的使用，以提高车辆到所有通信的可靠性（V2X）通信。 RIS单元的最佳位置问题是通过考虑其尺寸和操作模式来提出的。给出了问题的解决方案，其中显示RI的位置取决于发射器和接收器的位置。提议的RIS支持的高速公路部署可以抵抗使用高频频段（包括毫米波和Terahertz乐队）所经历的高道路损失，预计将在下一代无线网络中使用，这些网络将在下一代无线网络中使用，从而使现有的基本站部署计划使用可靠的可靠和能提供自动连接的实用性。
The use of real-time software-controlled reconfigurable intelligent surface (RIS) units is proposed to increase the reliability of vehicle-to-everything (V2X) communications. The optimum placement problem of the RIS units is formulated by considering their sizes and operating modes. The solution of the problem is given, where it is shown that the placement of the RIS depends on the locations of the transmitter and the receiver. The proposed RIS-supported highway deployment can combat the high path loss experienced by the use of higher frequency bands, including the millimeter-wave and the terahertz bands, that are expected to be used in the next-generation wireless networks, enabling the use of the existing base station deployment plans to remain operational, while providing reliable and energy-efficient connectivity for autonomous vehicles.
