Abstract
As the world continues to move toward a more efficient transportation system driven by connected and
autonomous vehicles (CAV), there is a growing demand for new technologies that guarantee efficient and
safe operation. Trust in CAVs hinges on the reliability of autonomy, including the crucial task of
positioning and navigation, which should be accurately provided at high precision everywhere for all
environments and operating conditions. The next-generation mobile networks (5G and 6G) operating in
the millimeter wave (mmWave) band is anticipated to transform modern societies by providing an ultrareliable, high-speed communications infrastructure. mmWave operates with high bandwidth, allowing for
high-resolution time-based measurements hence accurate range estimation. It also features massive
MIMO antennas, providing higher angular resolution and precise angle-based measurements. The use of
mmWave wireless networks for high-precision positioning in CAVs may have the potential to
significantly improve the safety and efficiency of transportation systems.
In this presentation, the recent advancements in mmWave wireless networks for high-precision
positioning will be explored, with a specific focus on navigating CAVs in densely populated urban areas.
The discussion will cover the development and implementation of a seamless positioning solution that
integrates the mmWave wireless network with the motion sensors onboard the CAV. Furthermore, the
presentation will examine how non-line-of-sight signals can be used for wireless positioning and how to
overcome the challenge of multipath in urban environments. The capabilities of achieving an
uninterrupted decimeter level of positioning accuracy will be demonstrated, making the developed
methods suitable for level three of autonomy. The presentation will showcase the performance of the
integrated mmWave wireless positioning solution using road test trajectories from downtown Toronto,
Ontario, Canada.
