Generic 5G Network Architecture
1. UPE
- Gateway
- U-plane mobility anchor
- OTA security provisioning
2. NI
- Extraction of actionable insights from big data
- Orchestration of required services and functionalities (e.g., traffic optimization, context-aware QoE provisioning, caching,…)
3. CPE
- Authentication
- Mobility management
- Radio resource control
- NAS-AS integration
4. RRU
- L1/L2 functions
- High CF with M-MIMO – for capacity
5. Macro cell
- L1/L2 functions
- Low CF with NOMA – fall back for coverage
- High CF with M-MIMO – wireless backhaul
6. Small cell
- L1/L2 functions
- Super high CF and/or unlicensed spectrum – for local capacity
- Switched on on-demand
7.
- Dual connectivity
- Independent C/U-plane mobility
8.
- Nesting and relaying to support low-powered devices, nomadic cells and group mobility
9.
- Connectionless, contention-based access with new waveforms for MTC asynchronous access
10.
- Network-controlled D2D
