With the large-scale deployment of 5G to various economic and social fields, a variety of innovative applications have emerged in many industries. At this year's trade fair, Qualcomm exhibited the "5G separate rendering VR Game", an innovative application created by Qualcomm in cooperation with China Mobile and Zhonghe Group. With the support of 5G high-speed, low-latency mobile network, viewers wearing portable head-display devices can turn into goalkeepers, take part in an "immersive penalty shootout" and experience a meta-universe experience of binocular 4K picture quality and latency less than 20 milliseconds.

Qualcomm is the world's leading wireless technology innovator, committed to the invention and innovation of basic technology for a long time, and continue to promote the development of mobile communication technology. For example, in Rel-15, the first version of the 5G standard, Qualcomm contributed an advanced channel coding scheme, which combines LDPC (low density parity) and ARQ (automatic retransmission request) to support high-speed data transmission speeds of up to dozens of Gbps while minimizing power consumption. In the new version of the 5G standard Rel-17, the millimeter wave band is extended to a new unique frequency range (from 52.6 GHz to 71 GHz), thanks to Qualcomm's 5G NR Extensible subcarrier spacing (SCS) scheme and slot-based flexible frame structure, this band extension extends the subcarrier spacing of control and data channels directly to 480 kHz and 960 kHz, helping to continuously unleash the application potential of 5G millimeter wave.

In addition to faster data transmission rate, 5G also has the advantages of low delay and high reliability. Meng Wei, chairman of Qualcomm China, said at the trade fair that 5G is very important for the digital future. As a key infrastructure of the digital economy, 5G has really become a general connection platform with excellent performance, reliability and capacity. It can provide better support for applications that require large bandwidth, low latency and high precision, and create a broader space for the development of the service industry. For example, the low latency of 5G helps to enhance real-time interaction and remote collaboration, so as to better support remote diagnosis, intelligent manufacturing and other application scenarios. At the same time, the large connection of 5G also provides a more reliable foundation for service innovation in the fields of intelligent transportation, smart city, smart home and so on.

Taking the "5G split rendering VR game" mentioned above as an example, with the high-speed and low-latency data transmission capability provided by 5G, people can collaborate to achieve separate rendering between the XR head display device and the edge cloud, so that XR users can feel an immersive experience free from cable shackles. At the award ceremony of the 5th "Blossom Cup" 5G Application Collection Competition sponsored by the Ministry of Industry and Information Technology last year, Qualcomm's "Unbounded XR based on Collaborative / separate rendering and 5G slices" project jointly completed by Qualcomm and Zhonghe Group, China Mobile Research Institute and Beijing Mobile also won the "Best International Application Award", indicating that 5G and XR fusion applications have broad prospects for development.

During this year's trade fair, Qualcomm also displayed "Qualcomm Invention Tree" in the booth, attracting many exhibitors to stop to browse and interact with each other. In addition to 5G, there are also basic inventions in the field of multimedia and Wi-Fi. In the multimedia field, the video codec technology promoted by Qualcomm provides support for modern high-quality video streaming, enables users to enjoy better quality and richer video content, and reduces the requirements for bandwidth and storage space. In the field of Wi-Fi, Qualcomm's breakthrough innovations in areas such as MIMO and OFDMA radio waveform design enable Wi-Fi to achieve high speed, high energy efficiency, and be able to cope with the increasing number of networking terminals in densely populated environments such as homes and offices.

In a word, the rapid development of 5G, XR, Wi-Fi, multimedia and other technologies is giving birth to more innovative applications, which not only improve people's lives, but also promote the sustained and rapid development of the digital economy. Data show that in 2022, China's digital economy reached 50.2 trillion yuan, accounting for 41.5 percent of GDP. Industry insiders predict that by 2025, the digital economy will account for more than 50% of China's GDP. The rapid development of digital economy means that all kinds of innovative applications will be more and more abundant, thus making our digital life more rich and colorful.
