Abstract

Vehicle-to-Everything Communication (V2X) is a technology that allows a vehicle to communicate with different entities of the traffic system. These entities include other vehicles (V2V), pedestrians (V2P), infrastructure like traffic signals (V2I) and application servers (V2N). V2X applications can transform existing transportation systems into Intelligent Transport Systems (ITS) that will provide intelligent services such as autonomous driving, collision warning, traffic regulation and infotainment.

IEEE 802.11p Wireless Access in Vehicular Environments (WAVE) based radio access has laid the foundation for V2X communication. It defines enhancements to IEEE 802.11 to support ITS applications. IEEE 802.11p allows vehicles to communicate their state, such as position and speed, to surrounding entities. However, though IEEE 802.11p gives acceptable performance in sparse networks, its performance deteriorates drastically in dense and high load conditions. In dense networks, the probability of collision of data packets increases significantly thereby reducing throughput and increasing delays.

Cellular V2X is the use of cellular radio access technologies like LTE for V2X. It has been shown that LTE V2X provides better performance in different network conditions and provides better mobility support than IEEE 802.11p. It is also suitable for most of the use cases of V2X. In this study, we have done systematic literature review of LTE and IEEE 802.11p based V2X. We present a technical overview of LTE V2X and describe a few important use cases. We also present a comparison of LTE V2X with IEEE 802.11p and highlight the benefits of using LTE for V2X.

Keywords

Abstract

Wireless technology has continuously evolved to cater to new applications and services. Till now, this evolution was mainly driven by the demand for high data rates. However, requirement for next generation wireless technology is much more than just high data rates. It is estimated that by 2025 there will be 25 billion wireless connections connecting people and things. This Internet of Everything (IoE) will continuously capture and exchange data. It will also be highly intelligent to aid quick decision making and to deliver high quality services. To achieve this, the underlying communication technology will have to be extremely reliable and should provide very low latency.

3GPP is working towards 5G technology, which is expected to be launched in 2020. Apart from supporting high data rates, it will also enable large scale IoE connectivity and extremely low latency applications. With 5G as the communication technology, AI enabled platforms can collect, exchange and store relevant data and can deliver more efficient products and services. This interworking of 5G and AI has the potential to bring a new era of intelligent connectivity that can drastically change our lives.

In this study, we have done systematic literature review of ultra-reliability and low latency (uRLLC) feature of 5G. We present an overview of uRLLC and also discuss some use cases of how 5G, AI and IoE can interwork to improve the lives of rural and urban population especially in important areas like Agriculture, Healthcare, Education and Transport.

Abstract

The demand for access to high-quality live media on handheld devices is increasing at an unprecedented rate. Mobile broadband users are demanding live streaming video content anywhere, anytime and on all their devices. This puts immense pressure on mobile network operators to provide quality services to all their subscribers within the limited radio resources that are available to them. Using a one-to-one dedicated connection to send the same content (for example, Live Sports action) to multiple users results in inefficient spectrum utilisation. Broadcasting/Multicasting allows network operators to offload content from dedicated services to shared services, thereby freeing-up network resources and improving spectral utilisation. This also enables network operators to use their existing infrastructure efficiently, thereby improving their ROI. Though technologies like 3G and LTE also support Multimedia Broadcast Multicast service (MBMS), 5G NR based Broadcast/ Multicast provides better performance as it has improved signal coverage even at cell edges and can also cater to high traffic demands in high mobility scenarios. The latency in 5G is also lower than 3G/LTE, thereby improving the overall end-user experience. In this study, we have done a systematic literature review of 3GPP Broadcast/Multicast services. We present an overview of 5G Broadcast/Multicast technology and discuss some techniques that can be used to optimise resource utilisation and improve user experience. We then present a comparison between 5G and LTE Broadcast/Multicast performance and discuss how 5G Broadcast/Multicast can be used not just for entertainment but also for improving essential aspects of human life like Education, agriculture, and agriculture Public Safety.
