Abstract

The race to search for innovative solutions to enable the Next Generation Mobile Communications (5G era) has recently begun worldwide. In early 2013, the European Commission announced that it would invest €50 million in 2013 for 5G research in multiple projects such as METIS, quickly followed by the formation of the Chinese Government-led IMT-2020 Promotion Group in February 2013, the initiation of the Korean Government-led 5G Forum in May 2013, and the formation of 2020 and Beyond Ad-hoc within ARIB (Association of Radio Industries and Businesses), Japan, in October, 2013. Recently the European Commission also announced that it would invest €700 million to 5G research through Horizon 2020 program. While the standardization of 5G specifications in standards bodies such as the Third Generation Partnership Project (3GPP) and the formal ratification of 5G standards by the International Telecommunication Union (ITU) are still several years away, many share the vision of targeting 2020 for the initial commercialization of 5G cellular with drastically enhanced user experience.

This talk presents the vision, requirements, and the key technologies envisaged for the 5G mobile communications in 2020 and beyond era. The requirements emerged for the 5G era include massive capacity with order of magnitude data rate improvement as well as uniform Gbps experience, reduced latency for delay sensitive services, massive connectivity supporting innumerable simultaneous connections, and all these demands with energy efficient as well as cost effective solutions. The talk will put forth a few key technologies ranging from air technologies and network design to services along with the recent R&D achievements proving the feasibility of the proposed technologies and showing a bright prospect of 5G.
