5g + XR: let the dream of "digital reality integration" shine into reality
2022-07-20
Put on the head display device, connect to the network, invite family and friends to break through the space-time limit, and enjoy a "football feast" in the virtual room through high-definition videos with different angles and playback speeds; Or immersively watch a concert and stand shoulder to shoulder with your favorite singers, bassists and guitarists in the center of the stage; Or use the way of digital avatar to experience a virtual fireworks show based on ultra-high network speed and ultra-low delay in the metauniverse... When 5g and XR collide passionately, the above application of "digital real integration" will shine from dream to reality. What kind of speed and passion will 5g + XR produce? 5g technology brings not only the improvement of network transmission rate, but also supports high-speed connection with low delay, solves many problems faced by XR industry, and promotes the further optimization of XR product form and function. Vertigo is a big problem faced by XR devices. "The data of user eye tracking and gesture recognition can be quickly transmitted to 5g base stations through 5g, and then connected to the edge cloud through 5g core network. In this process, the 5g connection delay is 20 milliseconds, while the delay of the whole process from user action to rendering to display is 70 milliseconds". Xu Jian, head of research and development in Qualcomm China, said that 5g's low delay performance effectively reduces the dizziness caused by picture delay and greatly improves the user experience. Another challenge faced by XR terminals is their large size and high energy consumption. "Through 5g connection, we can achieve excellent computing power distribution between the head display and the edge cloud, and put the important rendering with the highest delay requirements on the head display, and the large-scale rendering with high demand for computing power on the cloud." Xu Jian said, "when separate rendering is realized, the volume and power consumption of XR head display can be minimized, so that XR terminals can truly fly into thousands of households." Not long ago, China Mobile and Qualcomm showed the industry the results of 5g + XR separation rendering. This is the first demonstration of end-to-end collaborative separation rendering unbounded XR technology based on 5g slices in the industry. XR users use 5g high-speed, low latency network transmission to collaborate with the edge cloud side for real-time rendering, and combine local optimized rendering on the XR terminal side to provide a low latency immersive unbounded XR experience. The demonstration proved the horizontal expansion ability of 5g technology - the large-scale commercialization of unbounded XR and other new businesses that can support end-to-end collaborative separation and rendering, and opened a new chapter for the application and innovation of 5g slicing technology in the XR field. In addition, with the help of AI, the application of 5g + XR has been strengthened, pushing the user experience to a new level. The combination of the three technologies will not only have a far-reaching impact on the vertical industries such as construction and medical treatment, but also change people's lifestyle and the entertainment, shopping and learning experience of consumers. Such changes have quietly taken place in the smart sports scene. At the beginning of this month, Zhonghe group, China Mobile and Qualcomm jointly announced that they planned to explore a new path for the construction of "smart sports" by using 5g empowering unbounded XR. Based on the high-speed and low delay transmission provided by 5g slice, the experience scheme cooperates to realize separate rendering between XR head display devices and edge clouds, creates an immersive experience free from cable constraints for XR users for large load scenes, and enables innovative sports applications such as smart management and services of venues, panoramic free perspective live broadcast of events, immersive viewing of events, etc. Such changes are not just in the field of smart sports. In the key areas of the 5g application "sailing" action plan (2021-2023), 5g + information consumption, 5g + industrial Internet, 5g + smart education, 5g + cultural tourism and other fields also put forward a lot of demands for the integration of 5g and ar/ VR technology. To be sure, 5g + XR technology can play a big role in more vertical fields and lay a technical foundation for personal users and industrial users to create immersive experience anytime, anywhere. "Digital real integration" cannot be separated from industrial cooperation. Qualcomm has been working in the field of XR technology and market for more than ten years, and is committed to introducing the profound technology accumulation in the mobile field into XR. Through a new cooperation mode of open innovation, cooperation and sharing, and equal participation, Qualcomm has worked with a wide range of industrial chain partners to build an XR ecosystem. Qualcomm helps end-users build XR terminal products through two generations of XR dedicated platforms, and cooperates closely with many content, technology and platform companies, including XR headsets, accessories, smartphones and content service providers, to jointly promote continuous innovation in the XR field. As an important industry participant and promoter, Qualcomm also brings together more diversified industry best practices, resources and talents with the help of the new ecological cooperation model. At present, Qualcomm has held four consecutive "Qualcomm XR innovation and Application Challenge" and established XR innovation centers in Nanchang, Qingdao, Nanjing and Chongqing respectively; Qualcomm venture capital gathered more than 30 venture capital companies to establish XR industrial investment alliance to promote industrial innovation and large-scale development... With the joint efforts of the industry, the "multiplier effect" of XR industrial transformation and upgrading is gradually emerging. (Xinhua News Agency)
