AI Technical Summary

Technical Problem

Existing 5G networks face significant energy inefficiencies, particularly in radio access networks, with high energy consumption due to continuous operation of base stations even when no communication is occurring, and current energy-saving technologies primarily focus on user equipment rather than network-side solutions.

Method used

Implementing time-domain, frequency-domain, and spatial-domain technologies at base stations to dynamically adapt and reduce energy consumption, including methods such as reducing common channel/signals, dynamic bandwidth adaptation, UE grouping, and spatial element adaptation, along with network energy-saving configurations.

Benefits of technology

Enhances network energy efficiency by reducing static power consumption in base stations, thereby lowering operational costs and environmental impact while maintaining communication quality.

Abstract

A method for providing network energy saving configuration information for energy saving of an access network node to a user equipment (UE) is disclosed. The UE determines whether the measurement of a reference signal (RS) is restricted for energy saving of the access network node, and the UE configures the operation of the UE for the measurement of the RS based on the determination.
