6G-Uu
Next-Gen Extreme Terrestrial Radio Air Interface
The standardized physical and protocol air interface connecting 6G user equipment to 6G-gNB base stations across all frequencies up to 300 GHz.
Technical Explanation
The Uu interface is the defining air link between the user device (UE) and the radio access network (gNB). 6G-Uu represents the revolutionary leap beyond 5G NR-Uu: it supports multi-gigahertz channels in Sub-THz, sub-0.1ms transmission time intervals (TTI), integrated radar sensing signaling (ISAC), grant-free massive IoT access, and AI-native neural receiver pilot structures across a unified, scalable physical layer grid.
Key Functions
- Standardized physical, MAC, RLC, PDCP, and RRC air interface protocols for 6G
- Scalable numerology spanning legacy Sub-1GHz all the way up to 300 GHz Sub-THz
- Integrated radar sensing pilots, commands, and echo measurement reports
- Sub-100 microsecond TTI transmission frames for extreme low-latency HRLLC
- Native protocol support for Reconfigurable Intelligent Surface (RIS) control signals
