With the coming of 5g era, countries all over the world are competing for the right to formulate 5g standard. Does the first 5g standard release in the world increase your curiosity? Who will set the 5g standard? Huawei is a leader in this field. Let's learn together.
Release of the first 5g standard in the world
On December 21, 2017, at the 78th plenary meeting of 3GPP ran, the first version of 5g NR was officially announced to be frozen and released, half a year ahead of the planned release time.
The 5g NR version released this time is a part of 3GPP release 15 standard specification. The completion of the first 5g NR standard is an important milestone to realize the all-round development of 5g. It will greatly improve the capability of 3GPP system, create more opportunities for the development of vertical industries, and lay the foundation for the establishment of 5g ecosystem of global unified standard.
In the process of 5g standard formulation, Chinese operators and equipment manufacturers occupy a leading position. Wang Zhiqin, vice president of China Academy of communications, said that China has always been in the first tier of 5g industry in the world and is one of the chief designers of standards. According to China Mobile, the company has submitted more than 1000 proposals on 5g air port standardization to 3GPP, totaling more than 1.6 million words.
The first version of 5g standard is divided into two schemes: non stand alone (NSA) and stand alone (SA). As a transition scheme, non independent networking takes improving the frequency width of hot spot area as the main goal, relying on 4G base station and 4G core network work. Independent networking can achieve all the new features of 5g, which is conducive to giving full play to all the capabilities of 5g. It is an industry recognized 5g target scheme.
According to 3GPP's promotion schedule, 5g independent Networking (SA) standard will realize the freeze of functional part in June 2018, and complete the freeze of overall standard in the third quarter, when the first version of 5g global standard will be officially determined.
It is estimated that 5g will generate 12.3 trillion US dollars of economic output in the world by 2035, and its contribution to global GDP growth will be equivalent to that of India's economy of the same scale from 2020 to 2035.
Who makes 5g standard (China)
In the discussion of 5g short code scheme at the 87th meeting of 3GPP RAN1 just concluded, after arduous efforts and fierce competition, the scheme of polar code (polarization code) promoted by Huawei of China became the scene coding scheme of 5g control channel embB. This is a remarkable achievement in the history of communications, which will surely be recorded in history.
The discussion of short code is divided into control channel and data channel. Each company makes a comprehensive analysis of several candidate codes from the aspects of performance, implementation complexity and feasibility. The discussion at the meeting was extremely intense, with almost all companies participating in it, among which Huawei's proposal supported as many as 59 companies. And even in the early hours of the morning, there were still a lot of participants who focused on the coding scheme. They could only stand by and watch the war without gunpowder.
Coding and modulation are the core content in the field of wireless communication technology. Huawei people, through their own efforts, in the face of the challenge of LDPC camp led by American companies, although they are reluctant to lose in the competition of long code scheme, Huawei's optimized better polar code wins the final victory in the key short code, so that their own polar is launched Code (polarization code) scheme has become an embB scene coding scheme for 5g control channel, which is absolutely a historic moment, which means that in the future 5g field, this standard is the world standard, which means that the 5g technical standards of the world will be formulated by Chinese companies.
Looking back on the history of China's communication development, 3G has been squeezed into the international standard circle, 4G has used TD curve to overtake, 5g is trying to lead the world. This is the great change that has taken place in recent years. Through unremitting efforts, China Telecom has made a series of achievements in engineering technology. Although TD-SCDMA Technology is not mature enough, it makes China's communication technology catch up with the world for the first time. With the development of TD-LTE technology, China's communication technology has become one of the world's mainstream technologies for the first time. However, we need to see that the core long code turbo code and short code biting convolutional code are not original Chinese technologies.
In 5g promotion, China is recognized as the most active country, not one of them. Huawei is the most effective enterprise. The first 5g contribution award was given to Huawei. Huawei made a 5g trial network with a download speed of 115gbps three years ago. Please note that it is g or m. Now, the polar code led by Huawei finally breaks this ceiling, which is not only the return of years of careful research in the field of basic communication, but also the reflection of China's growing comprehensive strength in the field of communication technology. All the achievements will not be smooth. Polar code faces the strong competition of LDPC camp led by the United States, and the difference between several votes in the discussion of long code scheme is narrow. In the short code competition, the further optimized polar code King returns and wins the control channel short code victory.
It's estimated that Qualcomm will be in a cold sweat. We all know that Qualcomm's current strength in the field of wireless communication technology can be said to be too strong, which leads to the fact that the whole world, especially domestic manufacturers, have to look at their faces. The ugly point is to pay protection fees to Qualcomm. Then who can break Qualcomm's monopoly in the field of wireless communication technology?
In fact, it is clear that whoever dominates 5g standard can break Qualcomm's monopoly.
