5G Trials with world-leading vendors

Summary of DOCOMO's 5G Trials

5G is designed to achieve higher-speed, higher-capacity mobile communications making use of higher frequency bands (3GHz and above) and broader bandwidths (100s of MHz to over 1GHz) in addition to the lower frequency bands currently being used. In line with this view of 5G, DOCOMO is advocating the concept of Phantom Cell architecture, which consists of a combination of a small cell using a higher frequency band and broader bandwidth and a macro cell using a conventional lower frequency band. For 5G, DOCOMO is making research and development efforts with a focus on the development of technologies that enable efficient transmission in higher frequency bands such as the beamforming technology leveraging a large array of antenna elements (Massive MIMO) as well as technologies for efficient transmission in lower frequency bands.
Toward the goal of 5G service rollout, various mobile communication technologies and schemes need to be tested, including low-latency transmission methods that meet the needs of M2M and other various applications. To this end, DOCOMO is conducting experimental trials in collaboration with world-leading vendors to confirm the feasibility of a wide range of mobile communication technologies, centering on the concepts that DOCOMO advocates.
Active discussion on 5G was started in research institutes and international conferences in different parts of the world in 2013. DOCOMO has been engaged in studies on 5G since 2010, and is currently leading the 5G discussions underway in various research institutes and projects around the world. So far more than 150 papers were published in international and domestic conferences and journals.
In the next, DOCOMO intends to further extend its 5G research activities through future experimental trials and contribute to the worldwide efforts toward the commercial deployment of 5G.
