Study on Tethering AR Glasses – Architectures, QoS and Media Aspects
The present document addresses architectures, QoS and media handling aspects of when tethering AR Glasses to 5G UEs based on initial discussions in TR 26.998 [2]. In particular, the following aspects are in scope:
- Definition of different tethering architectures for AR Glasses including 5G sidelink and non-5G access based on existing 5G System functionalities
- Documentation of the relationship between AR Glasses tethering and AR glasses considered as PIN (Personal IoT Network) elements according to TR 22.859 [3] and the derived service requirements in TS 22.261 [4].
- Documentation of end-to-end call flows for session setup and handling
- Identification media handling aspects of different tethering architectures
- Identification of end-to-end QoS-handling for different tethering architectures and define supporting mechanisms to compensate for the non-5G link between the UE and the AR glasses
- Providing recommendations for suitable architectures to meet typical AR requirements such as low power consumption, low latency, high bitrates, security and reliability.
- Collaboration with relevant other 3GPP groups on this matter
- Identification of potential follow-up work on this matter
