AI Summary

This study addresses the stringent requirements of remote teleoperated driving, which demands ultra-reliable and low-latency communication that current networks struggle to fulfill. The work systematically evaluates the feasibility of 5G networks in this context, with a focus on how time-division duplex (TDD) frame structures and uplink/downlink bandwidth configurations affect end-to-end latency for video transmission and control commands. It further models system scalability under multi-vehicle concurrency. The findings reveal that specific 5G configurations can support remote driving, albeit at the cost of reduced video bitrates to accommodate more vehicles. Moreover, internet backhaul latency imposes a significant bottleneck on centralized architectures, highlighting their inherent limitations in meeting the most demanding latency constraints.

Abstract

Teleoperated driving (ToD) can support autonomous driving under complex or unexpected traffic scenarios that an autonomous vehicle may not understand or be able to handle. In ToD, autonomous vehicles transmit video feeds and perception data to the remote control center. The operator uses this data to understand the driving environment and remotely control the vehicle that can take over the control once the scenario is resolved. ToD requires reliable and low latency communications between the vehicle and the ToD control center. This study analyzes the feasibility to support ToD with 5G networks. The study demonstrates that the feasibility strongly depends on the bandwidth and the Time Division Duplexing (TDD) frame structure that conditions how the bandwidth is distributed between uplink and downlink transmissions. The study also shows that scaling the number of 5G-supported ToD vehicles requires the vehicles to reduce the video bitrates. The study also shows that traditional centralized 5G network deployments may be challenged by some of the most stringent ToD latency requirements due to the latency introduced by the Internet connection to the ToD control center.
