From 5G mobile phones, VR glasses to intelligent Internet connected cars, 5G, AI and other digital technologies are coming into people's lives in various ways, bringing a new application experience, which is supported by many innovative technologies. At this year's service trade fair, Qualcomm demonstrated a series of innovative technologies in 5G, Wi-Fi, multimedia and other fields in the form of an "invention tree", showing the important role of these innovative technologies in real life, attracting a lot of viewers to stop and browse and participate in interaction.

Among them, 5G, as a new generation of mobile communication technology, can be extended to more industries outside mobile phones and promote the Internet of everything. However, the demand for connectivity in different industries is different, and even there are significant differences, which poses a challenge to 5G technology. To this end, Dr. Ji Tingfang, vice president of engineering at Qualcomm, realized scalable OFDM parameter configuration by designing a unified subcarrier spacing exponential expansion formula, which is used to connect a wide variety of terminals, so that cellular connections can be extended to both ends of the complex spectrum outside the mobile phone with ultra-high efficiency, from ultra-low power Internet of things (IoT) sensors to ultra-low time delay and high throughput VR glasses. Promote more terminals to access the 5G network.

For the majority of consumers, the biggest change of 5G compared with previous generations of mobile communication technology is the faster data transmission speed, and the faster the generation and transmission of data, the more power is consumed in coding and decoding. The past 4G coding scheme is difficult to support the ultra-fast data transmission speed of 5G. In this regard, Qualcomm began to study advanced LDPC (low density parity) channel coding technology more than a decade before 5G was commercialized, and combined LDPC with hybrid automatic repeat request (ARQ, the basic link of cellular communication) to support data transmission speeds up to dozens of Gbps while minimizing power consumption. It means that consumers can also experience faster 5G speeds on small devices such as smartphones.

In addition, Qualcomm also focuses on promoting 5G technological innovation for the industry. For example, in terms of cellular vehicle networking (C-V2X), Qualcomm is involved in driving the development of Rel-14 and Rel-15 C-V2X technologies aimed at providing basic security features. On this basis, Qualcomm continues to promote the directly connected communication technology in Rel-16, bringing significant improvements in many aspects, such as higher throughput, lower delay and reliable distance-based multicast, which helps to improve the efficiency and safety of self-driving and semi-autonomous driving. In the new version of 5G standard Rel-17, C-V2X technology has been more enhanced, including supporting reliable communication between cars and pedestrians, cyclists, etc., and further improve the efficiency and safety of traffic operation. In addition, in terms of satellite communications and RedCap technology for the Internet of things, Qualcomm has also contributed a lot of 5G innovative technologies to support 5G expansion to more industries.

At this year's Service Trade Fair, the "5G fully connected Factory" project jointly created by Qualcomm and Chinese industrial partners was rated as the "demonstration case of scientific and technological innovation service". This is another practical case of Qualcomm working with partners to promote the application of 5G technology to the industry. The project is planned by the China Industrial Internet Research Institute, Qualcomm provides all-round technical support, and uses 5G modules deployed by China Telecom and 5G modules provided by Mobile Communications. During the progress of the project, according to the needs of the Kone elevator factory, all parties created a 5G technology network based on the support of Qualcomm solution. The powerful 5G technology solutions provided by Qualcomm and multi-party teams also help enterprises to solve the pain points in terms of efficiency, cost, security and so on. At present, the "5G fully connected Factory" project has achieved positive practical results, and a number of industrial interconnection applications have been realized based on 5G transmission technology.

Not only industrial manufacturing, 5G is also widely used in transportation, education, and many other industries to promote the sustained and rapid development of the industry. Forecast data show that by 2035, 5G will create 13.1 trillion US dollars in global economic output and bring 22.8 million jobs, with huge economic and social benefits. Therefore, it can also be believed that, with the joint promotion of all parties in the industry, 5G technology will continue to evolve and accelerate its application to thousands of industries, and make greater contributions to economic and social development.
