“…Doppler shift, frequency errors, and inter-carrier interference due to the very high relative speed of vehicles in highways are the existing challenges with the current PHY design of the LTE [1]. There are some efforts in the literature to apply LTE for vehicular networks [17][18][19]. [20], and its feasibility and architecture were studied in [21,22], respectively.…”

Long-Term Evolution (LTE) is a promising technology to be applied for different applications due to its high penetration, high data rate, reliability, and QoS support. One of the emerging applications for LTE is vehicular networks. Vehicular networks can raise traffic safety, improve traffic management, or provide infotainment services for road users. LTE device-to-device (LTE-D2D) communication which was proposed by 3GPP working group is also a good candidate to be applied for vehicleto-vehicle communications (V2V). The V2V communication for traffic safety has strict QoS requirements in terms of latency and reliability. LTE-D2D may provide high reliability and low latency for such a communication. However, an efficient radio resource management for V2V communications in an LTE network is required to support such requirements. In the current article, we introduce vehicular networks, their requirements, and existing technologies to be employed in them and specially look at LTE-D2D to connect cars. Most recent works in radio resource management for V2V communications in LTE are reviewed in this work.

“…In order to evaluate the QoS performance of the LTE network under realistic load conditions, a total number of 14 DL and 11 UL automotive services of the Infotainment, Comfort, and Traffic Efficiency domain have been simulated [43]. These services include a variety of current and future automotive off-board services as well as standard applications, such as web-browsing or e-mail.…”

The cellular communication networks standard 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) offers low latencies and high throughputs simultaneously, thus enabling 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 manifold quality of service requirements. This chapter analyzes the suitability of LTE as a wireless transmission technology for future vehicular services of the categories Infotainment, Comfort, Traffic Efficiency, and Safety. The investigations are based on extensive LTE system-level simulations under different load conditions and network deployments as well as on a theoretical delay analysis. Focus is set on transmission delays and reliability aspects under various quality of service settings. The results show that an accurate selection of the LTE quality of service parameters is crucial in order to meet the delay and reliability requirements of future automotive applications, especially in high-load network conditions. Keywords VANET • LTE • LTE- IntroductionImproving traffic safety, efficiency, and driver's comfort becomes more and more important for modern vehicles. At the same time, the demands for high data rate information and entertainment services grow.Modern vehicles are increasingly equipped with on-board advanced driver assistance services (ADAS) which process data from numerous on-board vehicle sensors. However, to further improve ADAS systems, it is required to enlarge the range of the sensors mounted at the vehicle by incorporating also information from the outside world. This can be obtained from cooperation with other vehicles or road infrastructure, known as vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), infrastructure-to-vehicle (I2V), or vehicle-to-X (V2X) communications. The IEEE 802.11p [36] standard specifies the communication technology for ITS applications in Vehicular Ad Hoc Networks (VANETs). Its advantages are easy deployment, low costs, mature technology, and the capability to natively support V2V communications in ad hoc mode. Nonetheless, this technology suffers from scalability issues and low penetration, unbounded delays, and lack of deterministic quality of service (QoS) guarantees [15]. Due to its ad hoc connectivity focus, its limited radio range and without a pervasive roadside communication infrastructure, IEEE 802.11p can only offer intermittent and short-lived V2I connectivity. These concerns motivate the investigation of wireless access technologies to support advanced V2I and V2V communications in vehicular environments. LTE [9] is the most promising wireless broadband technology that provides high throughput and low latency for mobile services. Like all cellular systems it benefits from a large coverage area, high penetration rate providing the economical basis for short development cycles, and high velocity terminal support.LTE particularly m...

“…At the moment, IEEE 802.11p based standards (DSRC and WAVE) and cellular based (LTE-A and future 5G) standards are the most promising standards for V2X communications. Recent studies have preferred using LTE as the V2X technology [6], [7], mainly because LTE cellular network infrastructure already exists [8].…”

Vehicles are the third fastest growing connected device type after smart phones and tablets. Also, automotive industry is interested to get more vehicles connected to the internet to improve traffic safety and efficiency. This creates a need for Vehicle-to-Everything (V2X) communications. In this work, the possibility of exploiting beamforming in LTE-V2X is considered. Singular value decomposition (SVD) receiver and precoder is implemented in an LTE-A system level simulator and the performance on multi-lane highway scenario is simulated and analyzed in downlink Vehicle-to-Infrastructure (V2I) scenario. The performance is compared to the conventional maximumratio combining (MRC) and LTE codebook precoded minimum mean square error (MMSE) receivers. In addition, the switchedbeam beamforming is imitated by modified antenna patterns with 7 and 15 narrow beams. The results show that the SVD receiver provides gain compared to the conventional MRC and MMSE receivers in ideal scenario. Furthermore, with modified antenna patterns, the performance was enhanced when compared to the default antenna pattern.Index Terms-LTE-V2X, vehicle, reliability, system level simulations, 5G.
