5G Advanced: Network Energy Saving
This course provides a comprehensive look into the Network Energy Saving (NES) features defined in 3GPP Releases 18 and 19. We will learn how these enhancements allow base stations to significantly reduce power consumption without compromising network coverage or user experience.
We will explore advanced techniques such as reducing power in Active Antenna Units (AAU), implementing "sleep" modes for cells (Cell DTX/DRX), and utilizing AI/ML for intelligent energy management. The course also covers critical new signaling mechanisms like SSB-less SCell operation and On-Demand system information that enable the network to transmit less energy when traffic is low.
Course Outline:
- R18 network energy saving features:
- M-MIMO Efficiency & Spatial Adaptation
- SSB-less SCell Operation
- NES-Conditional Handover (NES-CHO)
- Domain Adaptations:
- Time-Domain: Cell Discontinuous Transmission (Cell DTX) and Discontinuous Reception (Cell DRX) modes.
- Power-Domain: Dynamic adjustment of PDSCH transmission power
- R19 network energy saving features:
- On-Demand Signaling
- Advanced Adaptations: SSB periodicity adaptation and Paging/PRACH adaptations
- Wake-Up Signals (WUS)
- AI/ML for network energy saving
