Study on 6G Use Cases and Service Requirements for Future Cities

3GPP recently published a technical study that represents a major advancement in 6G technology. The Release 20 study item offers a comprehensive framework for 6G development by outlining the key use cases and service requirements for the future mobile system. The document details various use cases, including environment object reconstruction, road digitalization, collaborative service by immersive communication, real-time 6G network digital twin (NDT), and immersive media services by 6G non-terrestrial networks (NTN) connectivity. This paper presents a structured analysis of selected use cases for smart cities, including descriptions, pre-conditions, service flows, and potential new requirements for the 6G system.
