Huawei and China Mobile brings ‘0 Bit, 0 Watt’ energy saving solutions

Huawei and China Mobile have announced their all-new “0 Bit and 0 Watt” energy-saving solutions at Mobile World Congress (MWC) Shanghai 2023. These solutions provide technical upgrades for equipment and networks.

With new upgrades, the equipment can enter super-deep dormancy and be woken up whenever needed. The shutdown ratio of RF modules can reach 99%. The upgrades also achieve intent-driven smart network energy saving. This maximizes the energy efficiency of multi-band networks by applying an optimal strategy for each site at each time.

China Mobile and Huawei have been working on energy-saving innovations for wireless networks for the past five years. These two firms aim to achieve zero equipment and network energy consumption when there is no traffic.

The research also found that the key to “0 bit, 0-watt” equipment is minimizing energy consumption during off-peak hours while providing an instantaneous service experience. The key to “0 bit, 0 watt” networks is minimizing energy use throughout the day to meet differentiated performance requirements.

Let’s explore the equipment and networks for this solution.

0 bit, 0 watt equipment

• China Mobile Zhejiang and Huawei have already tested the “0 bit, 0 watt” equipment solution in Ningbo. The results confirm that this solution allows AAUs to enter super deep dormancy during off-peak hours, which reduces energy consumption to nearly 5 W, and to automatically wake up when the service load increases, in order to ensure user experience.

0 bit, 0 watt networks

• The China Mobile Research Institute and Huawei have deployed the “0 bit, 0 watt” network solution for complex scenarios. This solution applies intent-driven energy saving based on variables like scenario, service type, and rate target. Site-specific energy-saving policies are formulated to strike a balance between service experience and energy savings. Through joint verification, the China Mobile Research Institute and Huawei have demonstrated that this solution substantially reduces network energy consumption, with an average energy saving of 17.6% per day for 5G networks while the network KPIs stay stable.

“0 bit, 0 watt” innovations mark a milestone in China Mobile’s longstanding efforts to achieve service-based energy usage. Sun also added that the institute will continue to work with Huawei to maintain innovation efforts and meet both China Mobile’s and the country’s goals for carbon emission reductions.” said Sun Lei, a senior researcher at the Department of Wireless and Terminal Technology Research.

“0 bit, 0 watt” is one of Huawei’s major energy saving initiatives for wireless equipment and networks. Huawei will continue to work with China Mobile to apply the “0 bit, 0 watt” technology to more wireless products and explore more energy saving ideas, in order to help China Mobile and other operators worldwide build green 5G networks.” Noted Solari Yu, President of Huawei’s SingleRAN Product Line.
