In the 5G era, Chinese manufacturers will play a more important role. As the first mobile communication standard that China and the world have developed simultaneously, 5G has enabled China's industry to have a historical opportunity to achieve breakthroughs and surpass from deeper levels.
By the end of 2017, the 3GPP first edition of the NSA standard has passed, and it has taken a solid step away from the establishment and operation of the 5G commercial network. Today, China's IMT-2020 (5G) Promotion Team held the third phase of the 5G technology R&D pilot conference in Beijing and issued the first batch of specifications for the third phase of the 5G technology R&D experiment. Through the third phase of the 5G technology R&D test, it is expected that the main links of the 5G industry chain will basically reach the precommercial level by the end of 2018, promote the 5G to develop better and faster, and lay the foundation for 5G scale testing and commercialization. This will be achieved by 5G. A key step before commercial use.
The new era, Spreadtrum 5G layout and harvest
Wang Yanhui, secretary of the China Mobile Alliance, said that in the past few years, along with the rise of the mobile phone industry, the mobile phone industry chain including integrated circuits has also been intensively escalated. A group of leading semiconductor companies, including Hass and Spreadtrum, have emerged. Spreadtrum has already made it clear that 5G R&D is an important development strategy for the company's future. It has made special arrangements in terms of manpower and budget. Ziguang has provided great support for Spreadtrum’s 5G project. At present, Spreadtrum has set up a dedicated 5G product team, and stressed that the team must rely on national strategies. Under the support of the country and the leadership of the group, we should use the new 5G technology and international communication giants to return to the same starting line to achieve a leading communication company in the industry. The goal.
Different from the 2G, 3G, and 4G eras, China’s status in the industry in the 5G era has been comprehensively enhanced, and it is at the forefront of the world in terms of standards development, commercial progress, and mobile phone chips and terminal R&D. In order to break the monopoly and master autonomy, the layout of patents is of utmost importance. In this regard, Spreadtrum initiated the 5G core technology pre-research work from the beginning of 2015. At the same time, the members of the standardization team broke through a single point of technical understanding and systematically interpreted all aspects of the standard in depth to provide protection for prototypes and chip R&D.
In addition to self-study, Spreadtrum actively cooperates closely with domestic universities and scientific research institutes. The specific forms include 5G stock patent sharing and standardization advancement, and special topic cooperation research, which further enriches Spreadtrum’s patent reserves.
In addition to patents, Spreadtrum’s 5G product team broke through the conventions and developed terminal prototypes and chips almost simultaneously with standardization. Prototype Machine Spreadtrum based on a proprietary draft similar to the 3GPP specifications, completed the air interface test with the equipment vendor's base station equipment, through the Ministry of Industry and the Ministry of 5G two-stage scale test; chip, the algorithm platform according to each 3GPP meeting progress synchronously iterative Within one month after the NSA standard is clarified, a floating-point simulation platform that implements all features is output. At the same time, Spreadtrum completed the finalization of the terminal chip architecture according to the requirements of the 3GPP for terminal capabilities, and gave initial evaluation results in areas such as chip area and power consumption.
On January 16, the IMT-2020 (5G) Promotion Team released the first batch of specifications for the third phase of the 5G technology R&D experiment. Spreadtrum also closely follows the national timetable, adopting the PilotV2 prototype and the chip to advance in stages according to the third stage technical specifications, meeting the technical requirements of the 5G technology test terminal equipment, and completing commercial key technology verification and interoperability testing with the equipment. At the same time, a chip-level verification platform is used to evaluate and verify 5G terminal solutions, and the first chip supporting the 3GPP R155G standard is launched according to the third-phase timetable. In addition, Spreadtrum will also strengthen cooperation with its partners and promote the simultaneous development of 5G technology R&D and standards.
Ready to Embrace 5G Opportunities and Challenges
In 2016, Spreadtrum occupied approximately 27% of the market share in the global baseband market, and three points with Qualcomm and MediaTek. In the era of 5G, Spreadtrum clearly has to become a member of the first tier of commercial 5G terminal chips. In 2018, it will actively participate in the three-phase 5G field test of the Ministry of Industry and Information Technology. It will be based on a prototype platform in the early stage and based on the chip reference design in the later stage. Spreadtrum revealed that the first mobile chip supporting the 3GPP R155G standard will be launched by the end of 2018.
5G is a definitive opportunity. According to the forecast of the China Institute of Information and Communication Technology, by 2030, 5G will drive China’s direct economic output by 6.3 trillion yuan, economic growth value of 2.9 trillion yuan, and 8 million jobs; in terms of indirect contributions, 5G will drive total output. 10.6 trillion yuan, 3.6 trillion yuan in economic growth, and 11.5 million jobs.
Of course, the challenge can not be avoided. In terms of technology, Spreadtrum stated that the biggest problem currently facing the R&D process is the great flexibility of the 5G standard. The current standard only gives a large framework. Under this framework, various physical layer parameters closely related to terminal chip development are flexible and can be allocated, including bandwidth, subcarrier spacing, frame structure, and various physical layer references. Signals and so on. It can be said that under the existing framework, the combination of physical layer configurations that the terminal baseband implementation needs to support is almost “unbounded†without additional constraints.
In this regard, Spreadtrum, on the one hand, has reserved sufficient soft processing capabilities in the terminal architecture, and on the other hand, it has advanced with the industry's important partners, including equipment vendors and operators, in the framework of the 3GPP standard, facing different application scenarios and requirements. The product Profile definition further defines the "reasonable" specification.
In the market, for example, the smart phone market with slower growth has high hopes for 5G. Spreadtrum believes that the pre-cooling of the mobile phone market at the end of 2017 cannot be said to be a winter in the industry, but after a period of extraordinary development in the past few years, the whole has entered a platform period, and further growth will require new application catalysis. The company stated to Micronet that 5G technology innovation will bring more new application experience to smart phones in artificial intelligence, AR/VR, 4K/2K, etc., plus the Chinese government's strong support for 5G new technologies. It is bound to bring new opportunities and changes in the 5G smartphone market. How to improve the battery life and adapt to the flexibility of 5G technology all bring challenges to the design of the terminal chip. How to use the 5G technology to innovate new applications is also a task in which the 5G industry chain needs to think and improve simultaneously.
In response to the third phase of the trial, Director of the Department of Information and Communications Development of the Ministry of Industry and Information Technology Wen Kuo pointed out that the first is to closely follow the progress of international standards and accelerate the research and development of pre-commercial equipment; the second is to give play to the polymerization of the 5G technology research and development test platform and accelerate the building of a complete industry. The third is to combine 5G frequency planning, synchronously advance 3.5GHz and 4.9GHz R&D, and fourth, to promote the development of business applications.
Wang Yanhui said that in the 5G era, China has a greater say in standard setting, and China’s 5G commercial progress is also ahead of other countries. This gives Chinese equipment manufacturers and mobile phone brands opportunities to seize the first wave of opportunities in the market. The release of the 5G standard will accelerate the investment and layout of local brands in the industry, and will occupy an advantageous position in the future market competition.
In the 5G terminal chip design, chip companies must keep pace with the standard. One standard is locked, one is verified by the industry, and one is implemented. In addition to smart phones, 5G will surely embrace more market opportunities in the areas of industrial Internet, smart manufacturing, autonomous driving, drones, personal entertainment devices, and cloud applications.
