Rapporteur:  Dr. Stockhammer, Thomas

Extended reality (XR) refers to all real-and-virtual combined environments and human-machine interactions generated by computer technology and wearables. It includes representative forms such as augmented reality (AR), augmented virtuality (AV), mixed reality (MR), and virtual reality (VR) and the areas interpolated among them.
The present document collects information on eXtended Reality (XR) in the context of 5G radio and network services. The primary scope of this Technical Report is the documentation of the following aspects:
  • Introducing Extended Reality by providing definitions, core technology enablers, a summary of devices and form factors, as well ongoing related work in 3GPP and elsewhere.
  • Collecting and documenting core use cases in the context of Extended Reality
  • Identifying relevant client and network architectures, APIs and media processing functions that support XR use cases
  • Analysing and identifying the media formats (including audio and video), metadata, accessibility features, interfaces and delivery procedures between client and network required to offer such an experience
  • Collecting key performance indicators and Quality-of-Experience metrics for relevant XR services and the applied technology components.
  • Drawing conclusions on the potential needs for standardization in 3GPP.
