“…To satisfy KPIs and realize the vision of these futuristic applications, current vehicular networks require new enhancements to many underlying technologies. Inspired by the vision in [2]- [5], [7]- [9], the taxonomy of the enhancements to appear in 6G-enabled vehicular networks is summarized in Figure 4. Most technologies in the figure are still under development with various achievements, e.g., blockchain and massive MIMO.…”

“…6G thus can enlarge the interconnectivity for V2X services beyond the territories where conventional vehicular networks cannot afford, e.g., remote driving in remote areas or flying taxi. Multiple radio access technology (multi-RAT), which supports a device to connect to multiple cellular networks (e.g., 5G, 6G) [9], is also useful for enhancing network coverage for V2X applications when the old generation networks have not yet fully been phased out.…”

Twenty-two years after the advent of the firstgeneration vehicular network, i.e., dedicated short-range communications (DSRC) standard/IEEE 802.11p, the vehicular technology market has become very competitive with a new player, Cellular Vehicle-to-Everything (C-V2X). Currently, C-V2X technology likely dominates the race because of the big advantages of comprehensive coverage and high throughput/reliability. Meanwhile, DSRC-based technologies are struggling to survive and rebound with many hopes betting on success of the secondgeneration standard, IEEE P802.11bd. While the standards battle to attract automotive makers and dominate the commercial market landing, the research community has started thinking about the shape of the next-generation vehicular networks. This article details the state-of-the-art progress of vehicular networks, particularly the cellular V2X-related technologies in specific use cases, compared to the features of the current generation. Through the typical examples, we also highlight why 5G is inadequate to provide the best connectivity for the vehicular applications and then 6G technologies can fill up the vacancy.

“…To elaborate, assuming that the memory of the experience replay is available, we can consider the input states experienced in the memory, i.e. B 1 and B 2 , to be the feasible domain that is plugged into (5). This is because the other states are very unlikely to be traversed.…”

“…By its nature, the effectiveness of classical MAC protocols in 6G has recently been questioned [3]. In fact, emerging 6G applications are often mission-critical under non-stationary environments, such as drones and satellites in a nonterrestrial network (NTN) [4], autonomous cars in a vehicle-to-everything (V2X) network [5], and visuo-haptic immersive applications in the metaverse [6]. These applications cannot be supported without tightly fine-tuning MAC protocols.…”

Classical medium access control (MAC) protocols are interpretable, yet their task-agnostic control signaling messages (CMs) are ill-suited for emerging mission-critical applications. By contrast, neural network (NN) based protocol models (NPMs) learn to generate task-specific CMs, but their rationale and impact lack interpretability. To fill this void, in this article we propose, for the first time, a semantic protocol model (SPM) constructed by transforming an NPM into an interpretable symbolic graph written in the probabilistic logic programming language (ProbLog). This transformation is viable by extracting and merging common CMs and their connections while treating the NPM as a CM generator. By extensive simulations, we corroborate that the SPM tightly approximates its original NPM while occupying only 0.02% memory. By leveraging its interpretability and memory-efficiency, we demonstrate several SPM-enabled applications such as SPM reconfiguration for collision-avoidance, as well as comparing different SPMs via semantic entropy calculation and storing multiple SPMs to cope with non-stationary environments.
