Whitepaper promoting 6G communication system

The whitepaper summarises the related technical concepts and the expected diverse use cases of evolving 5G and new 6G communication technologies, as well as the technology components and performance targets.

Mobile communication systems typically evolve into the next generation over a period of roughly ten years; DOCOMO commenced its research into the commercial launch of 5G in 2010. In 2018, the company conducted successful radio wave propagation experiments at frequencies of up to 150GHz, levels which are expected to enable the much faster and larger-capacity communications that 6G will require.

DOCOMO will continue to enhance the ultra-high-speed, large-capacity, ultra-reliable, low-latency and massive device-connectivity capabilities of 5G technology. It will continue its research into and development of 5G evolution and 6G technology, aiming to realise technological advances including:

• The achievement of a combination of advances in connectivity, including ultra-high-speed, large capacity and low latency.
• The pioneering of new frequency bands, including terahertz frequencies.
• The expansion of communication coverage in the sky, at sea and in space.
• The provision of ultra-low-energy and ultra-low-cost communications.
• The ensuring of highly reliable communications.
• The capability of massive device-connectivity and sensing.
