5G 正在进行中，它是一个新兴平台，不仅旨在增强现有平台，还引入了大量需要超可靠低延迟通信的新颖应用。它是一种新的无线接入技术，为改造现有平台（例如 2G、3G、4G 和 WiFi）提供构建模块，以实现更大的覆盖范围、可访问性以及更高的蜂窝和设备网络密度。这意味着 5G 旨在满足各利益相关者的多样化通信需求。在利益相关者中，尤其是车辆将在系统和应用层面受益于5G。作者提出了使用 5G 提供的构建块进行车辆通信的教程视角。首先，我们确定并描述新兴车辆通信的关键要求，并评估现有标准以确定其局限性。然后，我们简要介绍了所采用的 5G 架构，并确定了其在车辆通信方面的一些有前途的显着功能。最后，在车辆通信的背景下探讨了关键的 5G 构建模块（即邻近服务、移动边缘计算和网络切片），并强调了相关的设计挑战。
5G is ongoing, and it is an emerging platform that not only aims to augment existing but also introduce a plethora of novel applications that require ultra-reliable low-latency communication. It is a new radio access technology that provides building blocks to retrofit existing platforms (e.g., 2G, 3G, 4G, and WiFi) for greater coverage, accessibility, and higher network density with respect to cells and devices. It implies that 5G aims to satisfy a diverse set of communication requirements of the various stakeholders. Among the stakeholders, vehicles, in particular, will benefit from 5G at both the system and application levels. The authors present a tutorial perspective on vehicular communications using the building blocks provided by 5G. First, we identify and describe key requirements of emerging vehicular communications and assess existing standards to determine their limitations. Then we provide a glimpse of the adopted 5G architecture and identify some of its promising salient features for vehicular communications. Finally, key 5G building blocks (i.e., proximity services, mobile edge computing and network slicing) are explored in the context of vehicular communications, and associated design challenges are highlighted.
