WS7 – Workshop on eXtended Reality (XR) for 5G and Beyond (5G-XR Pro)

Scope 

eXtended Reality (XR) is an umbrella term that brings AR (Augmented Reality), VR (Virtual Reality) and MR (Mixed Reality) under one term. XR is expected to become a new killer application in the 5G era and it is predicted that there will be over 100 million XR users by 2025 and 1 billion by 2030. Within 3GPP, many XR use cases have been identified such as 3D messaging, immersive 6DoF, immersive online gaming, remote assistance, realtime 3D communication, online shopping, and holographic communication. A common feature of these XR applications is the Real-Time Broadband Communication (RTBC). For example, growing resolution and frame rate will increase the downlink rate from 50~100 Mbps to 0.5~1 Gbps, and for strong-interaction applications and cloud rendering, the latency will be lowered from 100 ms to 5~10 ms. Furthermore, holographic communication requires nearly 50~100 Gbps peak rate and ms-level latency. 

Obviously, XR poses higher requirements of both capacity and latency on 5G networks and drives the evolution of 5G technologies. This workshop will mainly consider the air interface technologies which may help achieve the requirements for these XR applications. This workshop provides the opportunity for attendees from both academia and industry to exchange views on advanced XR technologies for 5G and beyond. 

The potential topics include, but are not limited to: 

  • XR quality evaluation metric/methodology 
  • Use cases, requirements, and standardization of 5G XR in 3GPP  
  • Coordination and cross-layer design for 5G XR 
  • Unequal error protection (UEP) techniques  
  • QoE or source aware based transmission 
  • Multi-stream transmission with different QoS requirements  
  • Time sensitive scheduling with broadband transmission for 5G 
  • Machine learning based video transmission 
  • Joint source and channel coding  
  • XR including AR/VR/MR mobility 
  • Advanced power saving techniques for XR devices  
  • Low-complexity advanced scalable video coding for XR 
  • Holographic and haptic communication

Invited Talks 

On the Challenges of Delivering Next-Generation XR Applications in the Internet
Dr. Gwendal Simon, Huawei, France

Abstract:
This talk introduces the rising challenges related to the delivery of content for novel multimedia applications, such as Augmented Reality, Virtual Reality, volumetric video, and personalized video. One of the main trends in the industry of creative media is the prevailing role of 3D scenes and objects in the creation chain. A growth in the amount of 3D objects that will have to be transported in the network is anticipated. We propose dedicated solutions for adaptive delivery of 3D scenes. We focus in this talk on the delivery of 3D textures and on edge computing delivery for immersive applications.

Networking for Holographic Teleportation Applications
Prof. Ning Wang, University of Surrey, UK

Abstract:
Live holographic teleportation has been widely deemed as a next-generation communication application enabled by cutting-edge extended reality (XR) technologies. It is expected that such type of media application will see its wider deployment across the whole Internet, allowing users to communicate with immersive experiences between any geographical locations around the global world. This talk first provides an overview of the holographic teleportation application, followed by the elaboration on its user Quality of Experiences (QoE) aspects. New network requirements and technical challenges in supporting holographic teleportation applications will also be discussed.

Optimal Wireless Streaming for 360 VR Video
Prof. Ying Cui, Shanghai Jiao Tong University, China

Abstract:
Virtual reality (VR) techniques provide a better quality of experience (QoE) in interactive applications and have vast applications in entertainment, education, medicine, etc. This talk focuses on adaptive 360 video streaming from a multi-antenna base station (BS) to multiple single-antenna users in a multi-carrier wireless system. Specifically, we maximize the video quality and minimize the rebuffering time for wireless streaming of one 360 video and multiple 360 videos, respectively, by optimizing encoding rate adaptation for each group of pictures (GOP) and transmission adaptation at each coherence block. We adopt rate splitting in the most general form to maximize the rate region. We formulate the two optimization problems as two-timescale non-convex problems and propose iterative algorithms to obtain KKT points. Finally, we numerically show that the proposed solutions achieve notable gains over existing schemes.
