What are the energy-saving measures for base station power supply systems

What is the energy-saving technology of base stations?

This technical report focuses on energy-saving technology of base stations. Some energy saving technologies since 4G era will be explained in details, while artificial intelligence and big data technology will be introduced in response to the requirement of an intelligent and self-adaptive energy saving solution.

How can a base station save energy?

There are two main methods of base station energy saving, including hardware and software.

What are the basic energy saving functions with multiple levels?

The basic energy saving functions with multiple levels are designed for different coverage scenarios, time of day and traffic loads. The recommended strategy for the fundamentals is as following: Symbol shutdown: symbol shutdown can be scheduled in millisecond level thus it can be applied to most scenario even during medium traffic load.

What is base station energy consumption index (ECI)?

Brief description about components of the base station Energy Consumption Index (ECI)—It represents the efficiency of BS power utilization. The lower value of ECI means greater EE as mentioned in Eq. 6 below. Its unit is J/bit.

Can 3GPP reduce base station energy consumption?

Conferences > 2023 IEEE International Confe... Aiming at minimizing the base station (BS) energy consumption under low and medium load scenarios, the 3GPP recently completed a Release 18 study on energy saving techniques for 5G NR BSs .

Do cellular network operators prioritize energy-efficient solutions for base stations?

Recognizing this, Mobile Network Operators are actively prioritizing EE for both network maintenance and environmental stewardship in future cellular networks. The paper aims to provide an outline of energy-efficient solutions for base stations of wireless cellular networks.
