Nokia Bell Labs and KDDI Research have partnered to advance 6G technology, focusing on improving network energy efficiency and resilience. The collaboration combines KDDI’s real-world network data and operational insights with Nokia Bell Labs’ expertise in energy consumption models and programmable network architectures. This joint research agreement, signed on November 5, 2025, builds on a long history of cooperation and aims to accelerate the development and deployment of sustainable, intelligent 6G networks. 

Under this new agreement, the two companies are conducting research in two key areas of 6G:

• mMIMO energy efficiency: New techniques for reducing base-station energy consumption while enhancing communication, specifically targeted at proposed 6G spectrum.
• Distributed programmable core network services for 6G: New mobile core technologies that will ensure continuous communication during infrastructure failures and natural disasters.

KDDI Research and Nokia Bell Labs will demonstrate their initial work in mMIMO energy efficiency at the Brooklyn 6G Summit Nov 5 – 7.

Peter Vetter, President, Core Research, Nokia Bell Labs:

“Tackling the inherent challenges in a new generation of networking requires close collaboration in the industry. Working side by side, KDDI Research and Nokia Bell Labs can advance the state of the art in networking thanks to different perspectives on the problems and possible solutions. Ultimately, the joint outcomes will make 6G a more resilient, efficient and intelligent technology.”

Satoshi Konishi, President and CEO, KDDI Research:

“Through our strategic and close collaboration with Nokia Bell Labs, we aim to accelerate R&D initiatives and further strengthen the ‘Power to Connect’ toward 6G. We strive to continuously deliver new value to our customers and make meaningful contributions to societal progress.”
