Field Trial on 5G Low Latency Radio Communication System Towards Application to Truck Platooning

Abstract

The fifth generation mobile communication system (5G) is designed to have new radio capabilities to support not only conventional enhanced Mobile Broadband (eMBB) communications but also new machine type communications such as Ultra-Reliable Low-Latency communications (URLLC) and massive Machine Type communications (m-MTC). In such new areas of URLLC and m-MTC, mobile operators need to explore new use cases and/or applications together with vertical industries, the industries which are potential users of 5G, in order to fully exploit the new 5G capabilities. Intelligent Transport System (ITS), including automated driving, is one of the most promising application areas of 5G since it requires both ultra-reliable and low-latency communications. We are actively working on the research and development of truck platooning as a new 5G application. We have developed a field trial system for vehicular-to-network (V2N) communications using 5G prototype equipment and actual largesize trucks in order to assess 5G capabilities, including ultra-low-latency, in automotive test courses in the field. This paper discusses the fundamental performance evaluation required for vehicular communications between platooning trucks, such as low-latency message communication for vehicle control and low-latency video monitoring of following platooning truck vehicles. The paper also addresses the field evaluation results of 5G V2N communications in a rural area. It clarifies the fundamental radio propagation issues at the leading and the following vehicles in truck platooning for V2N communications, and discusses the impact of the radio propagation over a road to the over-the-air transmission performance of 5G V2N communications.

Centralized and Distributed Control Framework Under Homogeneous and Heterogeneous Platoon

“…[46]. The platooning vehicles using 5G C-V2X with URLLC service are successfully implemented in real experiment by [47] with very low latency lower than 10ms. The packet loss is represented by Bernoulli distribution that can be expressed in (10).…”

Monitoring particle trajectories for wave function parameter aquisition in quantum edge computation

“…where (3) gives our formula in terms of ψ in the second line. According to the formulae (5), ( 6), ( 7), ( 8), it is obvious [22] that quantum mechanics is a classical causal mechanics under the deterministic fluctuation V q , (4).…”

“…By combining high-precision sensors, it is expected that AI-equipped robots perform even higher quality tasks. Connection with the IoT (Internet of Things) [3] also raises such expectations. Further in order to control such AI-equipped robots online, a computer that processes high loads at high speed is required.…”

Research on Traffic Adaptability Testing and Assessment Method of Connected Vehicle Under Platoon Driving Scenario

“…Based on the two algorithms, bidirectional-leader following (BDLF) communication topology and four CVs equipped with DSRC devices, field experiments were conducted under the scenarios of platoon formation, vehicle merging, and vehicle diverging [33]. Mikami et al developed a field trial system for vehicular-to-network (V2N) communications using 5G prototype equipment and actual large-size trucks and discussed the fundamental performance evaluation required for vehicular communications between platooning trucks [34].…”
