Abstract:
—Reliable data communication is essential for con nections that are increasingly intelligent and automated. The fifth generation of mobile networks offers major improvements over the previous generation, 4G, but is still not capable of offering a ubiquitous connection to meet the demands of the new applications and needs that are emerging. On the basis of this, the cellular network standard will require a new communications network and this will come in the new generation of mobile networks, called 6G. This new standard has been considered a key enabler for the smart information society of 2030. The 6G networks are expected to deliver superior performance over 5G and satisfy new emerging services and applications that integrate space, air, ground, and underwater networks to provide ubiquitous and unlimited wireless connectivity. There is a huge number of use cases that pose varying requirements, which include extreme mobility, extreme low latency, ultra-high data rates, high energy efficiency, enhanced security, as well as high reliability. From this perspective, it is necessary to consider some of the key features that can be fundamental for the construction of the 6G network architecture. In this article, we will list some main use cases like Digital Twins, Global Ubiquitous Connectivity, Remote Communications, and others, that will need the main 6G functionalities to work correctly and meet the expectations of the main 6G requirements so that it is possible to identify relevant points in the construction of a robust and flexible network architecture.
