Abstract

The integration of 5G (5th Generation) and TSN (Time Sensitive Networking) networks is key for the support of emerging Industry 4.0 applications, where the flexibility and adaptability of 5G will be combined with the deterministic communications features provided by TSN. For an effective and efficient 5G-TSN integration both networks need to be coordinated. However, 5G has not been designed to provide deterministic communications. In this context, this paper proposes a 5G configured grant scheduling scheme that coordinates its decision with the TSN scheduling to satisfy the deterministic and end-to-end latency requirements of industrial applications. The proposed scheme avoids scheduling conflicts that can happen when packets of different TSN flows are generated with different periodicities. The proposed scheme efficiently coordinates the access to the radio resources of different TSN flows and complies with the 3GPP (Third Generation Partnership Project) standard requirements.

5G 配置的授予调度可与 TSN 工业网络无缝集成

5G（第五代）和 TSN（时间敏感网络）网络的集成是支持新兴工业 4.0 应用的关键，其中 5G 的灵活性和适应性将与 TSN 提供的确定性通信功能相结合。要实现有效和高效的 5G-TSN 整合，需要协调这两个网络。然而，5G 并非为提供确定性通信而设计。在此背景下，本文提出了一种 5G 配置授予调度方案，该方案将其决策与 TSN 调度相协调，以满足工业应用的确定性和端到端延迟要求。当不同 TSN 流量的数据包以不同周期生成时，所提出的方案避免了可能发生的调度冲突。拟议方案有效协调了不同 TSN 流量对无线电资源的访问，符合 3GPP（第三代合作伙伴项目）标准要求。

期刊介绍： Computer and Communications networks are key infrastructures of the information society with high socio-economic value as they contribute to the correct operations of many critical services (from healthcare to finance and transportation). Internet is the core of today''s computer-communication infrastructures. This has transformed the Internet, from a robust network for data transfer between computers, to a global, content-rich, communication and information system where contents are increasingly generated by the users, and distributed according to human social relations. Next-generation network technologies, architectures and protocols are therefore required to overcome the limitations of the legacy Internet and add new capabilities and services. The future Internet should be ubiquitous, secure, resilient, and closer to human communication paradigms. Computer Communications is a peer-reviewed international journal that publishes high-quality scientific articles (both theory and practice) and survey papers covering all aspects of future computer communication networks (on all layers, except the physical layer), with a special attention to the evolution of the Internet architecture, protocols, services, and applications.
