The fifth generation (5G) of wireless networks promises to meet the stringent requirements of vehicular use cases that cannot be supported by previous technologies. However, the stakeholders of the automotive industry (e.g., car manufacturers and road operators) are still skeptical about the capability of the telecom industry to take the lead in a market that has been dominated by dedicated intelligent transport systems (ITS) deployments. In this context, this paper constructs a framework where the potential of 5G to support different vehicular use cases is thoroughly examined under a common format from both the technical and business perspectives. From the technical standpoint, a storyboard description is developed to explain when and how different use case scenarios may come into play (i.e., pre-conditions, service flows and post-conditions). Then, a methodology to trial each scenario is developed including a functional architecture, an analysis of the technical requirements and a set of target test cases. From the business viewpoint, an initial analysis of the qualitative value perspectives is conducted considering the stakeholders, identifying the pain points of the existing solutions, and highlighting the added value of 5G in overcoming them. The future evolution of the considered use cases is finally discussed.

5G 车载用例：技术要求、价值主张和前景分析


第五代 (5G) 无线网络有望满足以前技术无法支持的车辆用例的严格要求。然而，汽车行业的利益相关者（例如汽车制造商和道路运营商）仍然对电信行业在专用智能交通系统（ITS）部署主导的市场中占据领先地位的能力持怀疑态度。在此背景下，本文构建了一个框架，从技术和业务角度在通用格式下彻底检验 5G 支持不同车辆用例的潜力。从技术角度来看，开发故事板描述是为了解释不同用例场景何时以及如何发挥作用（即前置条件、服务流和后置条件）。然后，开发一种试验每个场景的方法，包括功能架构、技术要求分析和一组目标测试用例。从商业角度出发，对利益相关者进行定性价值角度的初步分析，确定现有解决方案的痛点，并强调 5G 在克服这些痛点方面的附加价值。最后讨论了所考虑用例的未来演变。
