Fifth-generation (5G) mobile networks aim to be qualified as the core connectivity infrastructures to address connected automated mobility (CAM), both from a technological and from a business perspective, for the higher automation levels defined by the automotive industry. Specifically, in some territories such as the European Union the cross-border corridors have relevance, as they are the cohesive paths for terrestrial transport. Therefore, 5G for CAM applications is planned to be deployed there first. However, cross-border contexts imply paramount communication challenges, such as seamless roaming, not addressed by current technology. This paper identifies relevant future 5G enhancements, specifically those specified by Third-Generation Partnership Project (3GPP) releases beyond Release 15, and outlines how they will support the ambitions of highly automated driving in cross-border corridors. In order to conduct this study, a set of representative use cases and the related communication requirements were identified. Then, for each use case, the most relevant 5G features were proposed. Some open issues are described at the end.
第五代（5G）移动网络旨在成为连接自动化移动（CAM）的核心连接基础设施，从技术和商业角度来看，都是为了满足汽车行业定义的更高自动化水平。具体来说，在一些地区，如欧盟，跨境走廊具有重要意义，因为它们是陆地运输的连贯路径。因此，计划首先在这些地区部署用于 CAM 应用的 5G。然而，跨境环境意味着存在重大的通信挑战，例如无缝漫游，这是当前技术无法解决的。本文确定了相关的未来 5G 增强功能，特别是第三代合作伙伴计划（3GPP）Release 15 之后指定的增强功能，并概述了它们将如何支持跨境走廊中高度自动化驾驶的雄心。为了进行这项研究，确定了一组有代表性的用例和相关的通信要求。然后，为每个用例提出了最相关的 5G 功能。最后描述了一些未解决的问题。
