With rising interest in autonomous vehicles, developing radio access technologies (RATs) that enable reliable and low latency vehicular communications has become of paramount importance. Dedicated Short Range Communications (DSRC) and Cellular V2X (C-V2X) are two present-day technologies that are capable of supporting day-1 vehicular applications. However, these RATs fall short of supporting communication requirements of many advanced vehicular applications, which are believed to be critical in enabling fully autonomous vehicles. Both DSRC and C-V2X are undergoing extensive enhancements in order to support advanced vehicular applications that are characterized by high reliability, low latency and high throughput requirements. These RAT evolutions-IEEE 802.11bd for DSRC and NR V2X for C-V2X-can supplement today's vehicular sensors in enabling autonomous driving. In this paper, we briefly describe the two present-day vehicular RATs. In doing so, we highlight their inability to guarantee quality of service requirements of many advanced vehicular applications. We then look at the two RAT evolutions, i.e., IEEE 802.11bd and NR V2X and outline their objectives, describe their salient features and provide an in-depth description of key mechanisms that enable these features. While both, IEEE 802.11bd and NR V2X, are in their initial stages of development, we shed light on their preliminary performance projections and compare and contrast the two evolutionary RATs with their respective predecessors.

Vehicle‐to‐vehicle communication can be effective in avoiding accident and traffic collision using dedicated short‐range communication (DSRC) in intelligent transportation systems. The problem of DSRC is it works in a short range of 1000 m and its frequency band cannot support a large number of users simultaneously, which leads to multiaccess interference, (MAI) noise, and low transmission rate. Multiaccess interference is referred as the overlapping of signals from different users in the network. A combination of the Worldwide Interoperability for Microwave Access (WiMAX) and the DSRC is proposed to improve the quality of service and network congestion using multiuser detection (MUD) and scheduling technique. This paper proposes a scheduling algorithm called league championship priority scheduling algorithm. In the league championship priority scheduling algorithm, the message will be sent on priority basis, depending on the bandwidth values and network coverage, so that MAI can be avoided. Moreover, MUD plays a major role in identifying the active users and nonactive users based on the condition of the threshold frequency and bandwidth. Thus, the implementation result shows that the proposed algorithm provides high‐transmission data rate and multiaccess interference can be avoided. The performance is evaluated to validate and estimate the performance of MUD and scheduling algorithm.

Collision avoidance is one of the most promising applications for vehicular networks, dramatically improving the safety of the vehicles that support it. In this paper, we investigate how it can be extended to benefit vulnerable users, e.g., pedestrians and bicycles, equipped with a smartphone. We argue that, owing to the reduced capabilities of smartphones compared to vehicular on-board units, traditional distributed approaches are not viable, and that multi-access edge computing (MEC) support is needed. Thus, we propose a MEC-based collision avoidance system, discussing its architecture and evaluating its performance. We find that, thanks to MEC, we are able to extend the protection of collision avoidance, traditionally thought for vehicles, to vulnerable users without impacting its effectiveness or latency.
