EXECUTIVE FORUM: 6G Use Cases, Requirements, and Key Capabilities
Abstract: Within the more-than-ten-year lifecycle of 6G, many aspects of our daily lives will be augmented by ultra-high speed and ultra-reliable wireless connections. Meanwhile, new technology enablers such as sensing, native AI, massive VLEO constellation are bringing new possibilities and new use cases to 6G with trustworthiness and sustainability as native features. It is envisioned that the use cases in 6G will not only include further enhanced communication oriented use cases, but also those with beyond communication purposes such as sensing and AI. In particular, 6G network functions will act as the fabric of the converged physical and cyber worlds.
The continuous deep learning in the digital world serves as AI engine for the physical world, providing real-time inferences to facilitate all decision making. This imposes major challenges on the radio interface design, requiring extremely high throughput and ultra-low latency. From the physical world to the cyber world — this is a typical uplink channel — the primary application is sensing and the collection of big data for machine learning (ML). How to efficiently support massive distributed AI learning and inference with low bandwidth and energy consumption will be key to enable a future of connected intelligence.
Inspired by these vision and new technology capabilities, clearly-defined new use cases, new requirements and key capabilities are to be identified, such an effort is carried out in ITU-R WP5D and NGMN. There are dozens of use cases proposed by different parties while there is also discussions on which cases demands new KPI dimensions, new air interface or network architectures different from 5G or its evolution to realize.
A WCNC panel at this time – one year after ITU-R vision study and one year away from the vison recommendation – on 6G use cases, requirements and key capabilities would be a perfect opportunity to exchange views and promote common understanding.
