Huawei: 6G Is a Leap Forward From 5G

During an international conference regarding 5G on August 9, Wang Jun, VP of Huawei’s wireless network product line and chief scientist of 6G, said that 6G does not simply constitute an upgrade from 5G, but a leap forward. A globally unified 6G standard is the way to go, according to Wang. In order to drive the R&D of 6G, Huawei says it will also work with its partners to promote global unified standards.

He mentioned that the 6G has a vision of leaping over the connection between people and things, moving towards the smart connection of everything. 6G is defined by adding intelligence and sensing capabilities to the three scenarios upgraded by 5G. 6G has six key technology directions: native intelligence, extreme connectivity, network awareness, star-ground convergence, native trustworthiness, and carbon neutrality.

The typical application scenarios of 6G include: distributed connected machine learning and connected AI, sensing, positioning and imaging, human-centric immersive communication, smart cities and smart living, full-featured Industry 4.0 and its evolution, and global coverage of mobile services.

6G features a multi-layer spectrum. Low band is used in the basic coverage layer, medium band in the capacity and coverage layer (new IF 7-15GHz), and high band in the ultimate experience layer. Overall, the low and medium bands are still the most economical way to achieve wide coverage. The millimeter wave band is maturing in 6G, and perception is the new driving force. The terahertz band injects unlimited possibilities for perception and communication.

The data transmission rate of 6G may reach 50 times that of 5G, and the latency is reduced to one-tenth of 5G. Meanwhile, 6G is far better in terms of peak rate, latency, traffic density, connection number density, mobility, spectral efficiency, and positioning capability.
