Nokia, KDDI test energy-efficient 6G base station technology | Computer Weekly

KDDI Research and Nokia developed technology to optimize how a base station manages network resources, improving data transmission efficiency and reducing energy consumption in 5G/6G infrastructure. The technology is labeled Intelligent 4D Resource Optimisation Technology. A joint research agreement aims to find additional ways to reduce network energy use, with results shared as 6G standards develop in 3GPP. The partners completed a proof-of-concept trial described as the first initiative to combine four-dimensional resources to deliver high-quality communications while reducing base-station power consumption on commercial equipment. The work targets growing traffic from video streaming, cloud services, and IoT, and anticipates 6G-era AI services that will require scaling and densifying base stations, increasing their number and energy demands.

"KDDI Research - the R&D arm of leading Japanese operator KDDI - has announced that it has worked with Nokia to develop technology to optimise how a base station manages network resources, improving the efficiency of data transmission and reducing energy consumption in 5G/6G infrastructure and realising sustainable 6G."

"The technology is being labelled as Intelligent 4D Resource Optimisation Technology, and Nokia and KDDI's joint research agreement will explore additional ways to reduce network energy use, and the findings will be shared with the industry as 6G standards in 3GPP continue to develop."

"KDDI Research and Nokia Bell Labs, Nokia's industrial research lab, concluded a joint research agreement on 6G in November 2025 and have been working together on the development of new technologies for the practical implementation of 6G. One of the themes of this joint research is the development of technologies that can simultaneously improve the communication quality of 6G base stations and reduce their power consumption."

"The partners said that their work to date has seen the successful conclusion of a proof-of-concept trial, described as the world's first initiative to combine four-dimensional resources to simultaneously achieve high-quality communications and reduced base station power consumption on commercial equipment."
