Device-to-Device (D2D) communications as an underlay to future 5G networks is being considered as a suitable platform for vehicular communication. Key in this regard is intelligent Radio Resource Management (RRM), which needs to provision adequate quality of service, in terms of the reliability and latency of vehicular transmissions. The classical approach building upon Channel State Information (CSI)...
Radio resource management plays a crucial role in the context of mobile Device-to-Device (D2D) communication with strict requirements on the quality of service. Addressing some of the faced issues we have previously defined a Location Dependent Resource Allocation Scheme (LDRAS). In this work we enhance its performance in heterogeneous radio propagation environments. To this end, we optimize the transmission...
We propose a novel unified radio frame structure and medium access control (MAC) protocol for low-latency and highly reliable vehicle-to-X (V2X) communications. The radio frame structure enables short latency transmission and the unified device-to- device (D2D) communication for V2X services. The unified MAC protocol simultaneously enables the cellular-assisted and ad-hoc D2D communications to enable...
In this paper, we analyze the capacity of future cellular networks with a Device-to-Device (D2D) underlay reusing cellular uplink radio resources. We consider two resource reuse strategies and observe the behavior of the two-tier network with respect to the per-user transport capacity in both network layers. Our results indicate that the trend of network infrastructure densification and the prioritization...
Cooperative intelligent traffic systems (C-ITS) will help improve the safety and efficiency of ground transportation by enabling the cooperation between traffic participants. Applications based on the C-ITS paradigm rely on vehicle-to-vehicle, vehicle-to-infrastructure, and vehicle-to-device (collectively, V2X) communication for the exchange of critical information and have very stringent Quality...
This paper provides a performance comparison of location-based and Channel State Information (CSI)-based resource allocation for device-to-device (D2D) communication. Our focus is on a system where the available cellular uplink resources are reused for the exchange of messages between vehicles in D2D underlay manner. In this context, we define a heuristic resource allocation algorithm with a spectral...
Device-to-device (D2D) communication as an underlay to future cellular networks has been recently considered as an efficient cell offloading and capacity increasing solution. In this paper, we propose to use the D2D underlay as a carrier for automotive safety applications with very strict quality of service and reliability requirements. We propose a location dependent resource allocation scheme (LDRAS)...
The new cellular communication standard 3GPP Long Term Evolution (LTE) promises high throughputs and low latencies, thus enabling even more bandwidth-demanding and real-time critical services for end-users. This is of particular interest for vehicle manufacturers who in the future intend to offer a huge variety of cooperative driver assistance services with different quality of service (QoS) settings...
