Project Overview

• 5G COHERENT aims to research, develop and showcase a unified programmable control framework for 5G heterogeneous radio access networks

• Flexible spectrum management combined with efficient network coordination

• Network graph and low layer abstraction for scalability and reduced control overhead

• Challenges addressed• A single architecture to support services of different nature (eMBB, MTC, URLLC services)

• Different radios, spectrum access modes, frequency bands, and network technologies need to be harmonized under 5G architecture

• E2E slicing

• 5G Control and Coordination
