“…The virtual cell allows approaches to be created centered on the user. It basically consists of several transmission points with an association pattern for each user and his/her respective mobility [59], [60]. The virtual cells are formed by the association of a user with several Transmission Points (TPs) around him/her.…”

“…For this, a controller is required to dynamically configure and manage virtual cells, which can be instantiated by network slice according to specific service requirements. Sahin et al [60] present a V-Cell concept, that can be applied in several V2X use cases where broadcast communications for a group of vehicles occur, for example, in Cooperative Awareness Messages (CAM) and Decentralized Environment Notification Messages (DENMs). For this, the authors have adopted the steps of intra-VC optimization (transmission weight selection), power control and admission control.…”

The very last wireless network technology, created to increase the speed and the connections responsiveness, the Fifth-Generation Network (5G) can transmit a great volume of data. It uses wireless broadband connections to support specific end-users and businesses services. It is specifically useful for the Internet of Vehicles (IoV), guaranteeing fast connections and security. The 5G network technology can be used to support Vehicle-to-Everything (V2X) communications and applications on autonomous vehicles. It can enable information exchanges between vehicles and other infrastructures and people. It can also provide a more comfortable and safer environment and accurate traffic knowledge. The traffic flow can be improved, reducing pollution and accident rates. The cellular network can be associated with V2X as a communicating base to offer enhanced road safety and autonomous driving, and also to offer the IoV connections. This survey presents the 5G technology evolution, standards, and infrastructure associated with V2X ecosystem by IoV. In other words, it presents the IoV supported by 5G V2X communications, considering its architecture, applications and also the V2X features and protocols, as well as the modes, the evaluation and the technological support in such combination. The contribution of this paper is a systematized study about the interaction among these three contents: IoV, 5G, and V2X. Eighty four works were selected to present concepts, standards and to identify the ways to overcome challenges. This survey aims to guide the development of new 5G-V2X services and technologies dedicated to vehicle communications, and also to indicate future directions. INDEX TERMS IoV, connected vehicles, 5G networks, V2X communications.

“…Yet, to serve automated vehicles and reap all the promised benefits, the proactive serving AP updating and radio resource management following the users' movements are required as a precondition. The strategies proposed in existing studies on user-centric access, including those dedicated to vehicular communications [33], [37], [38], are generally channel state information (CSI) based. In vehicular networks, their implementations will cause extremely high signaling overhead considering the small coverage of the APs and the high mobility of the automated vehicles.…”

“…The results show a tradeoff between capacity and handover rate. In [38], considering the typical DL broadcast traffic in vehicular networks, the user-centric access was extended such that a group of adjacent vehicles are served by a logical cell together. The authors worked on power allocation to maximize the number of served vehicle groups.…”

The cooperative perception of the driving environment via the sharing of locally sensed information among automated vehicles plays a fundamental role in ensuring the basic safety of automated driving in complicated public traffic. However, demanding requirements ranging from high data rate and large user density to ultra-high reliability and low latency, are imposed on the 5G network, which is considered the key enabler of cooperative automated driving. In this paper, we propose a novel ultra-dense 5G vehicular network architecture, which features the kinematic information aided user-centric access, to address these requirements. In particular, distributed local access and application centers (LAACs) are designed to perform application implementation and access control collectively, such that the kinematic information of the vehicles extracted at the application layer can be exploited in the dynamic management of network resources to sustain consistently high-performance wireless communications between vehicles and their serving LAACs. Focusing on the uplink transmission of the periodic cooperative sensing messages (CSMs), the possible design of key elements in the kinematic information aided user-centric access, including access point association, radio resource allocation, and mobility support, are discussed. Issues brought about by the practical network deployment and constraints are also considered. In addition, a practical benchmarking access strategy set, which addresses both the reliability and the latency requirements of CSMs, is proposed and evaluated by simulation under the freeway and intersection scenarios. INDEX TERMS Vehicular communications, user-centric access, ultra-reliable and low-latency communications, automated driving, cooperative perception.

“…To address this challenge, many researchers have proposed deploying more microcells, picocells, or relays, expecting to increase the capacity and coverage of the network [3]. However, these methods introduce new problems, such as large energy consumption, high deployment and maintenance cost, and so on [4][5][6].…”

Inspired by the increasingly mature vehicle-to-everything (V2X) communication technology, we propose a multihop V2X downlink transmission system to improve users’ quality of experience (QoE) in hot spots. Specifically, we develop a cross-layer resource allocation algorithm to optimize the long-term system performance while guaranteeing the stability of data queues. Lyapunov optimization is employed to transform the long-term optimization problem into a series of instantaneous subproblems, which involves the joint optimization of rate control, power allocation, and mobile relay selection at each time slot. On one hand, the optimization of rate control is decoupled and carried out independently. On the other hand, a low-complexity pricing-based stable matching algorithm is proposed to solve the joint power allocation and mobile relay selection problem. Finally, simulation results demonstrate that the proposed algorithm can achieve superior performance and simultaneously guarantee queue stability.
