5 Core Use Cases p. 53

This clause documents the core use cases and scenarios for AR/MR devices, which serve to extract requirements, functional structure, related media format, and protocols for the 5G systems. Parts of the use cases are derived from XR use cases in TR 26.928 based on the relevance to AR/MR device type. In addition, the other use cases and scenarios are collected in Annex A of this document.

Table 5-1 provides a list of all the collected use cases.
