In Version 4.0, the Architecture Working Group (WG) provides a consolidated view of the architectural efforts developed in the projects of the 5G PPP and other research efforts, including standardization. This serves not only to review the current state of the 5G architecture, but to also identify promising trends towards the next generation of mobile and wireless communication networks, namely 6G.

This is the fourth release of this white paper, while building on the previous versions, is focussed on the output of the 5G PPP Phase III projects in terms of the architecture for the integration of large infrastructures and vertical industries (also known as verticals), the long-term evolution of the 5G technologies and the service-specific features. The view consolidated in this white paper presents the current overview on the 5G Architecture as developed by these European research efforts.
