TLDR
Standards and weaknesses of LTE as an enabling technology for vehicular communications are analyzed, and open issues and critical design choices are highlighted to serve as guidelines for future research in this hot topic.Abstract:
A wide variety of applications for road safety and traffic efficiency are intended to answer the urgent call for smarter, greener, and safer mobility. Although IEEE 802.11p is considered the de facto standard for on-the-road communications, stakeholders have recently started to investigate the usability of LTE to support vehicular applications. In this article, related work and running standardization activities are scanned and critically discussed; strengths and weaknesses of LTE as an enabling technology for vehicular communications are analyzed; and open issues and critical design choices are highlighted to serve as guidelines for future research in this hot topic.read more

Blind Signal Classification for Non-Orthogonal Multiple Access in Vehicular Networks.
TL;DR: A NOMA transmission scheme that applies phase rotation to data or pilot symbols depending on the N OMA multiplexing format, as an aid to the blind detection is proposed and it is found that the proposed algorithm provides a gain of more than 1 dB compared to the existing blind signal classification methods and shows almost equivalent performance as the genie information scheme.

Enhancing IEEE 802.11p/WAVE to provide infotainment applications in VANETs
TL;DR: The proposed W-HCF (WAVE-based Hybrid Coordination Function) protocol leverages controlled access capabilities on top of the basic contention-based access of the IEEE 802.11p; it exploits vehicles' position information and coordination among WAVE providers in order to improve performances of delay-constrained and loss-sensitive non-safety applications.
