22 February 2024:

Nokia, SK Telecom (“SKT”), NTT and DOCOMO announced they have joined forces to develop the 6G AI-native air interface (AI-AI), a critical next-generation technology that could greatly boost network performance while increasing energy efficiency. The four companies will show a video demonstration of an AI-AI proof of concept at SKT’s booth at Mobile World Congress. SK Telecom is the leading telecom giant in South Korea having 5G deployment.

The main driving force behind this is the continuous collaboration between NTT and DOCOMO.

They stated “DOCOMO and NTT will continue to conduct trials in collaboration with major global and Japanese vendors as well as overseas telecom operators. They will further expand their partners and promote various initiatives that leverage their respective strengths, to research and develop various mobile communication technologies.

Through these efforts, DOCOMO and NTT aim to accelerate research and development that will contribute to the global standardization and commercialization of 6G.”
