Network Energy Savings (NES)
3GPP Rel-18 Network Energy Savings Architecture
Holistic framework in Release 18 (TR 38.864) defining multi-dimensional energy saving techniques across time, frequency, spatial, and power domains for base stations.
Technical Explanation
Base station power consumption represents over 70% of a mobile operator's operational electricity costs. 3GPP Release 18 standardizes Network Energy Savings (NES), establishing metrics, measurement intervals, and signaling mechanisms that allow gNodeBs to reduce power consumption dynamically by up to 40% during low and medium traffic periods without degrading user coverage or throughput SLAs.
Key Functions
- Defines multi-dimensional energy saving mechanisms across time, frequency, spatial, and power domains
- Establishes standardized Joules-per-bit and Watts-per-area Energy Efficiency (EE) KPIs
- Coordinates sleep schedules dynamically based on real-time and predicted user traffic loads
- Enables mobile network operators to cut base station grid power consumption by up to 40%
