Abstract (in Japanese) (See Japanese page) 
(in English) Currently, many operators worldwide are deploying Long Term Evolution (LTE) to offer faster access with lower latency and higher efficiency than its predecessors 3G and 3.5G. LTE-Advanced, which is an evolution of LTE and a “true 4G” mobile broadband, is under development and its initial service rollout is expected by 2015. Amid such a situation, the anticipated challenges of the future are so tremendous that there is a vastly increased need for a new mobile communications system with even further enhanced capabilities, namely a fifth generation (5G) system. Envisioning the development of a 5G system, NTT DOCOMO (hereinafter referred to as “DOCOMO”) started studies on future radio access (FRA) as early as 2010. The aim is to identify the future needs and requirements of 2020 and beyond and identify the right system concept and radio access technologies to address them. Today, several experimental trials with world-leading vendors are ongoing. The goal is to provide an initial 5G deployment in time for the Tokyo 2020 Olympic Games. 5G related discussions are ongoing in the ITU-R Study Group 5 Working Party 5D (WP5D), such as the development of a new Recommendation on “IMT Vision – Framework and overall objectives of the future development of IMT for 2020 and beyond”. Studies on 5G have gained interest worldwide as evidenced by the acceleration of efforts by governmental entities and several research bodies from both academia and industry. Many special sessions are also being held on the topic of 5G in international conferences. DOCOMO is actively contributing to 5G related global pre-standardization activities through the METIS project in Europe, the ARIB 2020 and Beyond Ad Hoc (20B AH) group in Japan, NGMN alliance, and other initiatives. This talk introduces 5G global trends and activities and provides DOCOMO’s ongoing 5G activities toward 2020 and beyond.
