Augmented Reality (AR) and Mixed Reality (MR) promise to provide new experiences for immersive media services. The form factors of the devices for these services are typically not expected to deviate significantly from those of typical glasses, resulting in less physical space for the various required components such as sensors, circuit boards, antennas, cameras, and batteries, when compared with typical smartphones. Such physical limitations also reduce the media processing and communication capabilities that may be supported by AR/MR devices, in some cases requiring the devices to offload certain processing functions to a tethered device and/or a server. This report addresses the integration of such new devices into 5G system networks and identifies potential needs for specifications to support AR glasses and AR/MR experiences in 5G. The focus of this document is on general system aspects, especially targeting visual rendering on glasses, and may not be equally balanced or equally precise on all media types (e.g. on haptics, GPUs).

The present document collects information on glass-type AR/MR devices in the context of 5G radio and network services. The primary scope of this Technical Report is the documentation of the following aspects:

• Providing formal definitions for the functional structures of AR glasses, including their capabilities and constraints,
• Documenting core use cases for AR services over 5G and defining relevant processing functions and reference architectures,
• Identifying media exchange formats and profiles relevant to the core use cases,
• Identifying necessary content delivery transport protocols and capability exchange mechanisms, as well as suitable 5G system functionalities (including device, edge, and network) and required QoS (including radio access and core network technologies),
• Identifying key performance indicators and quality of experience factors,
• Identifying relevant radio and system parameters (required bitrates, latencies, loss rates, range, etc.) to support the identified AR use cases and the required QoE,
• Providing a detailed overall power analysis for media AR related processing and communication.
