- Future 5G systems have set a goal to support mission-critical Vehicle-to-Everything (V2X) communications and they contribute to an important step towards connected and automated driving. To achieve this goal, the communication technologies should be designed based on a solid understanding of the new V2X applications and the related requirements and challenges. In this regard, we provide a description of the main V2X application categories and their representative use cases selected based on an analysis of the future needs of cooperative and automated driving. We also present a methodology on how to derive the network related requirements from the automotive specific requirements. The methodology can be used to analyze the key requirements of both existing and future V2X use cases.

- Among the key differentiators of 6G compared to 5G will be the increased emphasis on radio-based positioning and sensing. These will be utilized not only for conventional location-aware services and for enhancing communication performance but also to support new use case families with extreme performance requirements. This article presents a unified vision from stakeholders across the value chain in terms of both opportunities and challenges for 6G positioning and sensing as well as use cases, performance requirements, and gap analysis. Combined, this motivates the technical advances in 6G and guides system design.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Vehicular networks are expected to empower auto mated driving and intelligent transportation via vehicle-to-everything (V2X) communications and edge/cloud-assisted computation, and in the meantime Cellular V2X (C-V2X) is gaining wide support from the global industrial ecosystem. The 5G NR-V2X technology is the evolution of LTE-V2X, which is expected to provide ultra-Reliable and Low-Latency Communications (uRLLC) with 1ms latency and 99.999% reliability. Nevertheless, vehicular networks still face great challenges in supporting many emerging time-critical applications, which comprise sensing, communication and computation as closed-loops.

- Localization of user equipment (UE) in mobile communication networks has been supported from the early stages of 3rd generation partnership project (3GPP). With 5th Generation (5G) and its target use cases, localization is increasingly gaining importance. Integrated sensing and localization in 6th Generation (6G) networks promise the introduction of more efficient networks and compelling applications to be developed.

Forskningsöversikt (refereegranskat)abstract
- Herein, we focus on convergent 6G communication, localization and sensing systems by identifying key technology enablers, discussing their underlying challenges, implementation issues, and recommending potential solutions. Moreover, we discuss exciting new opportunities for integrated localization and sensing applications, which will disrupt traditional design principles and revolutionize the way we live, interact with our environment, and do business. Regarding potential enabling technologies, 6G will continue to develop towards even higher frequency ranges, wider bandwidths, and massive antenna arrays. In turn, this will enable sensing solutions with very fine range, Doppler, and angular resolutions, as well as localization to cm-level degree of accuracy. Besides, new materials, device types, and reconfigurable surfaces will allow network operators to reshape and control the electromagnetic response of the environment. At the same time, machine learning and artificial intelligence will leverage the unprecedented availability of data and computing resources to tackle the biggest and hardest problems in wireless communication systems. As a result, 6G will be truly intelligent wireless systems that will provide not only ubiquitous communication but also empower high accuracy localization and high-resolution sensing services. They will become the catalyst for this revolution by bringing about a unique new set of features and service capabilities, where localization and sensing will coexist with communication, continuously sharing the available resources in time, frequency, and space. This work concludes by highlighting foundational research challenges, as well as implications and opportunities related to privacy, security, and trust.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter presents a brief background and motivation for cellular vehicle-to-everything (C-V2X), connected automated driving (CAD), and connected road user (CRU) services, including key technical terminology. Although sensor technologies have been and are used for ITS services, performance is severely degraded in non-line-of-sight (NLOS) situations and certain weather conditions. Hence, radio technologies are considered a crucial enabler for ITS, with a special focus on CAD. The chapter describes the ambitions of the telecommunication and automotive industries for a joint roadmap for CAD. It then goes into more detail about communication technologies for CAD and the standardization organizations. The chapter also provides an overview of the key concepts discussed in this book. The book describes the ecosystem around CAD, including business aspects and standardization as well as technical solutions enabling successful delivery of such systems from a communication perspective.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- When entities share knowledge from their local surroundings, awareness among drivers and automated vehicles can increase immensely and lead to safe and efficient intelligent transport systems (ITS). The ability to connect and share information is the enabler for connected automated driving (CAD) services. Also, non-ITS related services for road users are evolving and require interoperability and trust between service providers. In this chapter, the authors analyze and forecast further research and development (R&D) and standardization needs in C-V2X regarding broader aspects of CAD as well as for connected road users (CRU). They provide stakeholder recommendations to accelerate the development of the CAD ecosystem in terms of regulation, manufacturing, and operation. Overall, CAD enabled by C-V2X will be a paradigm shift in the way transportation is perceived today, and will bring important societal advantages in terms of safer roads, individual time spent commuting, and cleaner air, addressing increasing climate change concerns globally.
