The standardization for the fifth generation (5G) of mobile and wireless networks is at its early phase and has recently completed the first study item in Release 14. Nevertheless, there is a consensus that 5G will address the diverse service requirements of high-variety use cases. The network shall cope with such variation effectively and cost-efficiently even though the requirements can change over...
We explore the feasibility of 5G for enhancing cooperative automated driving. A V2X solution for enhancing road safety through connected cars based on 5G radio technology is shown. Based on a flexible, re-configurable software defined radio test-bed, we examine the benefit of ultra low latency and high reliability (URLLC) profile for enhanced emergency brake maneuver. This use case reveals the advantages...
Ensuring low-latency and highly reliable communication between vehicles is one of the goals of 5G. We present a 5G Vehicle-to-everything (V2X) wireless testbed based on flexible and re-configurable software defined radio that is designed for cooperative automated driving. The use-cases and communication requirements for cooperative automated driving are discussed to motivate the system design and...
Mobile networks are experiencing the avalanche of data traffic, which is coupled with the billions of wirelessly connected data-intensive devices using diverse multimedia services and applications. Prospective studies suggest that traffic volume would increase a thousand-fold over the next decade. Furthermore, the users expect the utmost in quality with seamless connectivity to the broadband access...
Device-to-Device (D2D) communications underlaying cellular network exploits physical proximity of the devices and aims at enhancing resource utilization, coverage, data rates and Quality of Service (QOS). Further, it enables the network operators to offload conventional network routed traffic to direct peer- to-peer links and could also support new application fields, such as Machine-to-Machine (M2M)...
During the last two years, the METIS project ("Mobile and wireless communications Enablers for the Twenty-twenty Information Society") has been conducting research on 5G-enabling technology components. This paper provides a summary of METIS work on 5G architectures. The architecture description is presented from different viewpoints. First, a functional architecture is presented that may...
Device-to-Device (D2D) communication underlaying cellular communications takes advantage of physical proximity of devices to improve coverage, resource utilization, data rates, QoS,and offers network operators the possibility to offload normally network-routed traffic to direct P2P links. This paper presents a novel Resource Allocation (RA) concept for D2D User Equipment(D-UEs) reusing the Physical...
The METIS project is laying the foundation of 5G mobile and wireless communication systems putting together the point of view of vendors, operators, third party players and academia. In particular, METIS is developing and evaluating the key technology components of 5G systems. In this framework, a new mobile and wireless network architecture is required to accommodate those technical enablers and...
Next generation mobile and wireless communication systems beyond 2020, aka Fifth Generation (5G) systems, aim at providing ubiquitous user experience with the utmost in quality. One of the promising technologies targeted for 5G systems is the flexible network deployment based on nomadic nodes (NNs). An NN is a low-power movable access node that provides coverage extension and capacity improvement...
