Abstract

Autonomous vehicles and Intelligent Transport Systems (ITS) have started to become a reality in recent years. However, shortcomings of these early intelligent vehicles demonstrate a need to increase an intelligent vehicle’s perceptual bubble beyond the vehicle’s onboard sensors. Vehicle-to-Everything (V2X) communications is a technology intended to enable intelligent vehicles to increase their perceptive range via communication with the outside world, i.e., other vehicles, road users, and infrastructure. One of the critical layers of V2X communications is that of the underlying wireless access. There remains an open debate on which technology (or technologies) will ultimately be adopted as the de facto wireless access technology for V2X communications. Presently, a myriad of unconnected threads of work are being undertaken to this end, resulting in an unclear picture of the current state of wireless access for V2X communications. In this tutorial review, we collate current research on wireless access for V2X communications to showcase recent developments and the challenges facing candidate technologies. To allow the reader to engage with the debate, we present an overview of the field of V2X communications, its history, and standardisation. Following this, we provide an overview of the key candidate wireless access technologies that may enable V2X communications. Through this work, we aim to provide a comprehensive first step into the discipline of wireless access for V2X communications.

V2X 通信的无线接入：研究、挑战和机遇

近年来，自动驾驶汽车和智能交通系统（ITS）已开始成为现实。然而，这些早期智能车辆的不足之处表明，有必要增加智能车辆的感知范围，使其超出车载传感器的范围。车对物（V2X）通信是一项旨在使智能车辆通过与外界（即其他车辆、道路使用者和基础设施）通信来扩大感知范围的技术。V2X 通信的关键层之一是底层无线接入。关于哪种（或哪几种）技术将最终被采用为 V2X 通信的实际无线接入技术，目前仍存在争议。目前，各方正在为此开展大量互不关联的工作，导致 V2X 通信无线接入的现状不甚明朗。在这篇教程综述中，我们整理了当前有关 V2X 通信无线接入的研究，以展示最近的发展和候选技术所面临的挑战。为了让读者能够参与讨论，我们概述了 V2X 通信领域、其历史和标准化。随后，我们概述了可实现 V2X 通信的主要候选无线接入技术。通过这项工作，我们旨在为 V2X 通信的无线接入学科迈出全面的第一步。

期刊介绍： IEEE Communications Surveys & Tutorials is an online journal published by the IEEE Communications Society for tutorials and surveys covering all aspects of the communications field. Telecommunications technology is progressing at a rapid pace, and the IEEE Communications Society is committed to providing researchers and other professionals the information and tools to stay abreast. IEEE Communications Surveys and Tutorials focuses on integrating and adding understanding to the existing literature on communications, putting results in context. Whether searching for in-depth information about a familiar area or an introduction into a new area, IEEE Communications Surveys & Tutorials aims to be the premier source of peer-reviewed, comprehensive tutorials and surveys, and pointers to further sources. IEEE Communications Surveys & Tutorials publishes only articles exclusively written for IEEE Communications Surveys & Tutorials and go through a rigorous review process before their publication in the quarterly issues. A tutorial article in the IEEE Communications Surveys & Tutorials should be designed to help the reader to become familiar with and learn something specific about a chosen topic. In contrast, the term survey, as applied here, is defined to mean a survey of the literature. A survey article in IEEE Communications Surveys & Tutorials should provide a comprehensive review of developments in a selected area, covering its development from its inception to its current state and beyond, and illustrating its development through liberal citations from the literature. Both tutorials and surveys should be tutorial in nature and should be written in a style comprehensible to readers outside the specialty of the article.
