Intelligent Transportation Systems in the Context of 5G-Beyond and 6G Networks

The role of wireless communications in guaranteeing safe and resource-efficient intelligent transportation systems (ITS) is of great significance. With the advent of a new technological epoch in cellular network development, various novel technical solutions are being considered as key enablers for future 5G-beyond and 6G networks. In this position paper, we identify and discuss three key pillars in the wireless network evolution that we suppose to be the foundation for the practical deployment of mass ITS. We first show how edge-located solutions may help in data delivery, next we present the role of the integrated communications and sensing paradigm (ICAS) in vehicular communications, and finally, we concentrate on advances in cellular-based sidelink communications.
