Next Generation Mobile Networks Alliance says four use cases The group identified four key use cases or capabilities presently seem most germane for guiding the development of 6G mobile networks.
Enhanced human communication such as immersive experience, telepresence and multi-modal interaction.
Enhanced machine communication for sensing the surrounding environment and the need for robots to communicate among themselves and with humans.
Enabling services such as high accuracy location, mapping, environmental, or body sensing data.
Network evolution to include artificial intelligence (AI) as a service, energy efficiency and ubiquitous coverage.
This approach of identifying important use cases was used to guide the development of 5G, the NGMN says, using the same approach in its thinking on 6G.
But the group itself notes that, with respect to 5G, “changes in services and consumption have influenced network developments in ways that were unforeseen when 5G use cases were proposed.”
At this point, it is equally possible that the designed-for use cases are not those the 6G network will be called upon to support.
Compared to 5G, 6G--to support the identified use cases--might therefore require a network able to use new higher-frequency bands and a new air interface natively supporting localized coverage and short ranges.
The 6G network could also require the ability to coordinate service delivery to multiple devices simultaneously, using a variety of media types.
The 6G network should be better able to predict activity, rather than merely responding. Three-dimensional positioning and tracking capabilities also are a desired capability (think control of unmanned aerial vehicles).
Real-time mapping also is a desired feature. Also, better support for artificial intelligence functions is desirable, especially to integrate sensing, communication, learning and computing.
The ability to integrate non-terrestrial platforms also is expected.
