The six departments work together to compose movements in our symphonies of innovation.

• WT

  The Wireless Technology Department is committed to cutting-edge research in wireless technologies. Its mission is to promote wireless technology innovations, so as to develop core technologies for sustainable growth of the mobile communications industry.
  As 5G mobile communications systems have been commercially used globally, the Wireless Technology Department has launched preliminary research on the next-generation 6G mobile communications systems. This will consolidate and establish DOCOMO’s global leadership position in the ICT field. 6G will provide significantly better performance compared to 5G. It will result in the deep integration of the cyber and physical worlds, and promote the sustainable development of society.
  The Wireless Technology Department is conducting research on key wireless technologies that is centered around high-frequency and ultra-wide bandwidth systems to achieve extreme performance of 6G. It involves three main technologies, namely non-orthogonal physical layer design (NOPHY), extreme multiple-input, multiple-output (Extreme MIMO), and AI-based physical layer design (iPHY).
  At the same time, the Wireless Technology Department actively participates in domestic 6G technology seminars, including IMT-2030 Promotion Group, CCSA New Wireless Technologies Working Group, FuTURE Mobile Communications Forum, Millimeter Wave, and Terahertz Alliance. This will help promote exchanges between China and Japan in new wireless technologies.

• AI

  The AI Technology Department is dedicated to the research and development of computer vision and natural language processing technologies related to new business innovation.
  The department is focused on the application of artificial intelligence technology to research and innovation in the areas of mobile Internet and big data, and supporting new businesses and new business models through advanced technologies such as deep learning. The current work revolves around innovative research on the four levels of theory, technology, platforms and applications, and is focused on the areas of computer vision and natural language processing. It strives to generate disruptive innovations in the basic theory and key technologies of artificial intelligence, and actively promote the cross-integration of artificial intelligence technology and wireless communication networks to make computers more beneficial for humanity.

• PFD

  The Platform Development Department is dedicated to 3GPP standardization, wireless commercial networking and services, and artificial intelligence-related platforms and systems development.
  The department develops and maintains system-level and link-level simulation platforms for wireless communication system technology research. It provides one-stop services for the pre-research evaluation of advanced technologies, advancing the standardization of key technologies and the optimized selection of pre-commercialized technology, and it provides comprehensive support for patent applications, article publication and technical reports.
  The department develops and maintains simulation platforms for new wireless services and new applications. It supports the development and innovation of big data-driven businesses and applications, and based on data mining and machine learning, provides relevant modeling, optimization and evaluation support for various business applications such as image understanding and retrieval, and natural language processing.

• SL

  The Solution Department is committed to applying artificial intelligence (AI) technology into efficient solutions for wireless communication networks.
  With the dawn of the 5G+ era, the complexity of wireless communication networks is also increasing exponentially. The Solution Department focuses on solution design, verification and innovation of new technologies, especially AI technology, to improve network efficiency and performance.
  Its current work focuses on research into combining scheduling, channel prediction and beam management in 5G system access layer with deep learning techniques. Its goal is to significantly improve the performance and efficiency of wireless communication networks at a lower cost by introducing data-driven and algorithm-driven AI technologies.

• ST

  The Standardization Technology Department has been deeply involved in the field of 3GPP standardization for many years. It has substantial technical experience and brilliant achievements from 4G LTE to 5G NR. DBL participated in the standardization meeting for the first time in 2006 and has contributed proposals. Henceforth, the Standardization team has continued to grow. It has been more deeply involved in the standardization work of 3GPP RAN1 since LTE Release 10, and has also contributed numerous proposals.
  It has made outstanding contributions to the successful completion of the 5G Rel-15/16 standardization by deploying 5G NR in advance, thus establishing DOCOMO’s leading position among telecommunications operators. In the 5G NR research, the Department is involved in standardization tasks such as mmWave, NR MIMO, URLLC/IIoT, IAB, channel coding, scheduling and controls, flexible duplex, NOMA, cellular vehicle networking as well as drones. With the dawn of the 5G Evolution, the Department is actively working towards the continued consolidation of core technologies on key topics of the 5G network future evolution.
  The Standardization Technology Department has always been committed to promoting beneficial technologies and views for networks and users to be in line with international standards. It has also actively supported the development of commercial networks at the headquarters. It has hundreds of international patents and essential patents for standardization in the above-mentioned sectors.
