Quality of experience of extended reality (XR) applications over 5G networks

XR增强现实(AR)、混合现实(XR)和虚拟现实(VR))应用开始在工程、游戏和教育等许多领域得到采用。这些应用程序使得在一组分散的参与者之间实现身临其境的丰富协作成为可能。5G技术的出现拓宽了这些应用的覆盖范围，因为它们比所有前辈和有线网络的覆盖范围都更好。终端用户体验质量(QOE)是这些应用程序的关键考虑因素。要获得真正身临其境的体验，这些应用程序必须提供实时反馈和交付。TELUS、Red Iron Labs和加州大学之间合作的广泛目标是设计和构建一个端到端的XR平台，在该平台中，XR组件(例如视频处理和XR渲染)作为微服务部署在核心云和边缘云中。我们的目标是提供一个平台，以性能感知的方式在5G网络上部署XR和其他沉浸式应用程序，增强感知的用户体验。我们的工作将为在教育和医疗模拟等领域利用XR技术带来新的机会，为我们的合作伙伴以及这些领域的其他加拿大组织提供竞争优势。该项目将培训HQP掌握加拿大IT和电信行业非常需要的UX、XR、微服务、云计算和边缘计算等技能。

XR Augmented Reality (AR), Mixed Reality (XR), and Virtual Reality (VR)) applications are beginning to be adopted in many domains such as engineering, gaming, and education. These applications make it feasible to achieve immersive and rich collaboration between a distributed set of participants. The advent of 5G technology broadens the reach of these applications since they have better coverage than all its predecessors and wired networks. End user Quality-of-Experience (QoE) is a key consideration for these applications. For a truly immersive experience, these applications must provide real-time feedback and delivery. The broad goal of the partnership between TELUS, Red Iron Labs and U of C is to design and prototype an end-to-end XR platform, in which XR components (e.g., video processing and XR rendering) are deployed as microservices in both core and edge clouds. The goal is to provide a platform for deploying XR and other immersive applications over 5G networks in a performance-aware manner, enhancing perceived user experiences.Our work will spark new opportunities for exploiting XR technologies in sectors such as education and medical simulations providing a competitive advantage to our partners as well as other Canadian organizations in these areas. The project will train HQP with skills such as UX, XR, microservices, cloud computing, and edge computing that are in high demand within Canada's IT and telecom sectors.
