毫米波通信最近被提议作为一种很有前途的候选方案，以满足自动驾驶强加的连通性要求。自动驾驶汽车对每秒多吉比特传输能力的需求是毫米波技术的主要驱动因素。然而，还有其他最重要的要求，例如短延迟、高可靠性、安全性以及对单播和广播通信的支持，在这项技术成为现实之前，必须仔细解决这些要求。在本文中，我们首先回顾正在考虑用于车辆通信的最先进的建模框架。然后，我们将探索将增强毫米波通信对自动驾驶的适用性的关键技术，并调查需要克服的主要挑战。最后，我们展望了模拟/混合波束形成与基于位置的波束搜索协议的结合，使用全双工无线电和物理层密钥生成，具有满足自动驾驶技术要求的潜力。
Millimeter-wave communications have been recently proposed as a promising candidate to fulfill the connectivity requisites imposed over autonomous driving. The need for transmission capabilities of multiple gigabits per second for autonomous vehicles is the main driving factor for millimeter-wave technology. However, there are other paramount requirements, such as short delays, high reliability, security, and support for both unicast and broadcast communications, which must be carefully addressed before this technology becomes a reality. In this article we first review the state-of-the art modeling frameworks that are being considered for vehicular communications. Then we explore the key technologies that will enhance the suitability of millimeter-wave communications for autonomous driving, and we investigate the main challenges that need to be overcome. Finally, we envision that a combination of analog/ hybrid beamforming with a location-based beam search protocol, using full duplex radio and physical layer key generation, has the potential of fulfilling the requirements of autonomous driving technology.
