Background: 4G research outcome of over 1Gbps data transmission


Original Aims of Super3G

Basic concept (Original aims)

Long term evolution of 3G

Evolve 3G technologies by maintaining

competitiveness

Provide a smooth introduction path to

4G

Background

At the start of standardization in 2004,

interest in 4G was low

In 2008, for the proposal to ITU-R IMT-

Advanced, it was clearly indicated that LTE

Advanced should be an evolution of LTE

Conclusion

5G discussion is heated unusually, and differently from 4G discussion ten years ago. This is good for accelerating the standardization process, but on the other hand, negative opinions may frustrate its progress.

5G will be launched in 2020 in an advanced market and then it will penetrate to the global market. 5G will continue to evolve after its launch in the same way that 4G LTE continues to evolve to LTE-Advanced and further enhancements.

No single 5G technology today, but a new technology will be

created by combination of technologies; Massive MIMO, Advanced C-RAN, NOMA and so on.

5G covers a wide variety of use cases and wide range of frequency bands. It is a big challenge to meet both requirements for extremely low power consumption and extremely high speed by a single 5G system.

DOCOMO targets 5G launch in 2020.

We are communicating with standards people so that the specifications be released by the end of 2018.

We expect collaboration with another advanced market South Korea trying 5G trial at Winter Olympics in 2018.
