“…Many stakeholders (e.g., 3GPP, IEEE) have already announced the draft standards or technical reports that detail new opportunities of V2X-enabled vehicles for the cellular and automotive industries [20]. V2X is able to warn drivers about dangerous situations and intervene through automatic braking or steering if the driver is unable to avoid an accident; besides, platooning (road-trains) and highly automated driving can reduce travel time, fuel consumption and CO 2 emissions while improving road safety and traffic efficiency [21].…”

The rapid development of intelligent control technology has also brought about changes in the automotive industry and led to development of autonomous or self-driving vehicles. To overcome traffic and environment issues, self-driving cars use a number of sensors for vision as well as a navigation system and actuators to control mechanical systems and computers to process the data. All these points make a self-driving car an interdisciplinary project that requires contribution from different fields. In our particular case, four different university departments and two companies are directly involved in the self-driving car project. The main aim of the paper is to discuss the challenges faced in the development of the first Estonian self-driving car. The project implementation time was 20 months and the project included four work packages: preliminary study, software development, body assembly and system tuning/testing of the self-driving car. This paper describes the development process stages and tasks that were distributed between the sub-teams. Moreover, the paper presents the technical and software solutions that were used to achieve the goal and presents a self-driving last mile bus called ISEAUTO. Special attention is paid to the discussion of safety challenges that a self-driving electrical car project can encounter. The main outcomes and future research possibilities are outlined

“…The selection for the best RAT is based on several factors including the number of V2X UEs using a given technology, the presence of RSUs, the information configured by the network (e.g., mapping between application ID and RAT), or QoS-related requirements. The use of multi-RAT to improve the V2X communication reliability is addressed in [43]- [45]. The authors in [43] evaluate different, independent and coordinated transmission schemes, where packets are transmitted through both the LTE-Uu and PC5 interfaces.…”

On 5G-V2X Use Cases and Enabling Technologies: A Comprehensive Survey

5G technologies promise faster connections, lower latency, higher reliability, more capacity and wider coverage. We are looking to rely on these technologies to achieve Vehicle-to-Everything (V2X) communications, which increase the safety and autonomy of vehicles in addition to road safety, saving energy and costs. The integration of vehicular communication systems and 5G is the subject of many research. Nowadays, researchers address challenges such as automated and intelligent networks, cloud and edge data processing, network management, virtualization, security, privacy and finally interoperability. This paper provides a survey of the latest V2X use cases including requirements, and various 5G enabling technologies under consideration for vehicular communications. Subsequently, we first provide an interesting mapping between the three 5G pillars and V2X use case groups. Then, we present a summary of potential applications of enabling technologies for V2X use case groups. Finally, the open directions of research are discussed, and the challenges that await to be met are pointed out.

5G Functional Architecture and Signaling Enhancements to Support Path Management for eV2X

et al. 2019

Enhanced vehicle-to-everything (eV2X) communication is one of the most challenging use cases that the fifth generation (5G) of cellular mobile communications must address. In particular, eV2X includes some 5G vehicular applications targeting fully autonomous driving which require ultra-high reliability. The usual approach to providing vehicular communication based on single-connectivity transmission, for instance, through the direct link between vehicles (PC5 interface), often fails at guaranteeing the required reliability. To solve such a problem, in this paper, we consider a scheme where the radio path followed by eV2X messages can be proactively and dynamically configured to either transmit through a single interface (chosen between the PC5 and the Uu interface for infrastructure-based communication) or through both interfaces simultaneously, depending on the requirements and particular situation. After describing some path management general considerations, we propose a new network function and a procedure to enhance the current capabilities of the 3GPP 5G system. Next, we propose different architectures to support our proposal following the four 5G eV2X architectural options defined by the 3GPP. For each alternative, the necessary signaling for the dynamic configuration of the radio paths is detailed. Finally, an exemplary use case of our proposal is presented in detail to illustrate the feasibility of our proposed functional architectures, and, for that use case, system-level simulation results are provided to demonstrate the benefit achieved with dynamic path management.
