Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a method to achieve more seamless handover control in V2I communication using O-RAN, attracting attention as a new open and bright RAN architecture in coordination with NR V2X and connected autonomous vehicles (CAVs).
CAV is expected to achieve safety and efficiency, which could not be achieved by mimicking human driving or sharing information from roadside units and other vehicles. However, there are issues with the degradation of wireless quality due to vehicle movement in the wireless communication system of cooperative autonomous driving. To solve this issue, we aim to realize a system that integrates and coordinates information from vehicles and base stations.
In this study, we aim to solve various wireless communication issues by linking O-RAN with cooperative autonomous driving, transmitting data held by cooperative autonomous driving to roadside units, and utilizing it at base stations installed at the roadside units.
Using a traffic simulator, we evaluate a beam management method for vehicles moving between multiple roadside units and report the results.
