System model and architecture for mobile integrated access and backhaul in advanced networks

Abstract

Facilitating operation and support of mobile relays based on an integrated access and backhaul concept for advanced networks (e.g., 4 G, 5 G, 6 G, and beyond) is provided. An embodiment relates to a communication network architecture that can comprise a control plane architecture of a relay node device. The control plane architecture can comprise a star-type architecture. Further, the communication network architecture can comprise a user plane architecture of the relay node device. The user plane architecture can be separated from (or independent of) the control plane architecture. Further, the user plane architecture can comprise a multi-hop architecture. The relay node device can be configured to operate according to a fifth generation wireless network communication protocol, or other advanced communication protocols.
