[Invited Lecture] DOCOMO's Activities for 5G
Yukihiko Okumura (NTT DOCOMO) RCS2015-182
Abstract (in Japanese) (See Japanese page) 
(in English) In order to prepare for the rapid growing of mobile data traffic that the spread of smart phones/tablets and various mobile applications/services cause and for the anticipated 1000-fold increase in 2020s’ data traffic volume compared to 2010, it is expected that the fifth-generation (5G) mobile communication system to dramatically improve the capability of the radio access network (RAN) will be introduced in 2020. In this talk, system performance requirements in the 5G RAN and approaches of performance improvement of the radio access to satisfy the requirements are described. In addition, the technical concept of the 5G radio access exploiting higher frequency bands (SHF/EHF bands) based on the phantom cell concept is shown as DOCOMO’s activities for 5G realization, and the radio access technologies (RATs) which achieve super high capacity, super high data rates, and low latency are introduced. Moreover, propagation experiments in high frequency bands, transmission experiments to establish the 5G radio interface and massive MIMO technologies are introduced as the experimental verifications.
