This article provides some fundamental indications about wireless communications beyond LTE/LTE-A (5G), representing the key findings of European research project 5GNOW. We start with identifying drivers for making transition to 5G networks. Just name one, advent Internet Things and its integration conventional human-initiated transmissions creates a need system redesign. Then we make clear that strict paradigm synchronism orthogonality as applied in LTE prevents efficiency scalability....
Cellular systems of the fourth generation (4G) have been optimized to provide high data rates and reliable coverage mobile users. next will face more diverse application requirements: demand for higher exceeds 4G capabilities; battery-driven communication sensors need ultra-low power consumption; control applications require very short response times. We envision a unified physical layer waveform, referred as generalized frequency division multiplexing (GFDM), address these requirements. In...
Two emerging technologies in the automotive domain are autonomous vehicles and V2X communication. Even though these usually considered separately, their combination enables two key cooperative features: sensing maneuvering. Cooperative allows to exchange information gathered from local sensors. maneuvering permits inter-vehicle coordination of maneuvers. These features enable creation vehicles, which may greatly improve traffic safety, efficiency, driver comfort. The first generation...
Information exchange among vehicles, and between vehicles the roadside infrastructure is commonly regarded as a base technology to sustainably reduce road accidents improve traffic efficiency. After more than decade of research development efforts, technological basis has been established that applies WiFibased, wireless communication in 5.9 GHz frequency band, ad hoc dedicated message sets, well management security procedures. In Europe, Release 1 standards for cooperative systems...
Vehicular communication (VC) systems have the potential to improve road safety and driving comfort. Nevertheless, securing operation is a prerequisite for deployment. So far, security of VC applications has mostly drawn attention research efforts, while comprehensive solutions protect network not been developed. In this paper, we address problem: provide scheme that secures geographic position-based routing, which widely accepted as appropriate one VC. Moreover, focus on currently chosen...
In federated learning, all networked clients contribute to the model training cooperatively. However, with sizes increasing, even sharing trained partial models often leads severe communication bottlenecks in underlying networks, especially when communicated iteratively. this paper, we introduce a learning framework FedD3 requiring only one-shot by integrating dataset distillation instances. Instead of updates other approaches, allows connected distill local datasets independently, and then...
Despite great advantages of vehicular ad hoc networks (VANETs), they also introduce challenges with respect to security and privacy. Today, people are more concerned about their Using unique identifiers for communication, a vehicle can easily be located tracked. Alternatively, technical solution protect drivers' privacy is the use changing pseudonyms. Existing work mainly focuses on algorithms pseudonym change neglect practical implications realizability. For deployment integration...
Sensor data sharing enables vehicles to exchange locally perceived sensor among each other and with the roadside infrastructure increase their environmental awareness. It is commonly regarded as a next-generation vehicular communication service beyond of highly aggregated messages in first generation. The approach being considered European standardization process, where it relies on detected objects representing anything safety-relevant, such or pedestrians, periodically broadcasted direct...
Vehicle-to-infrastructure and vehicle-to-vehicle communication has recently garnered considerable attention from both academia industry because it holds the potential to improve road safety reduce accidents. For this reason, V2X been considered a key technology of future Intelligent Transportation Systems. Use cases for enhancing intersection are appealing intersections most complex dangerous driving environments. This article reviews major related work presents architecture that supports...

Simulation results encoded are included further comparison.
Bird's eye view (BEV) perception is becoming increasingly important in the field of autonomous driving. It uses multi-view camera data to learn a transformer model that directly projects road environment onto BEV perspective. However, training often requires large amount data, and as for traffic are private, they typically not shared. Federated learning offers solution enables clients collaborate train models without exchanging but parameters. In this paper, we introduce FedBEVT, federated...
