How is the Huawei incident? Huawei embraces 5g cloud leading future

Huawei is one of the top mobile phone brands among domestic mobile phones, and it is also the leader among domestic mobile phones. In 2018, Huawei also raised a big step in the real sense. Huawei made 5g network standard! How are the netizens concerned about Huawei's events? Huawei embraces 5g cloud leading future!

China 5g standard

At the 78th plenary meeting of 3GPP ran, the first version of 5g NR was officially frozen and released. With the implementation of the first 5g standard, it can be expected that there will be a wave of discussion on 5g investment boom. This includes the 5g investment plan of telecom operators, relevant application services driven by the 5g network construction, and even the upstream and downstream industry chains of the new generation 5g mobile terminals. Because the first version of 5g standard is officially established, the market will start to have more associations and expectations for 5g's future business opportunities.

Leading the 5g Era

5g, the fifth generation mobile phone mobile communication standard, also known as the fifth generation mobile communication technology. Wang Feng, who has many years of working experience in the information and communication industry, said in an interview with China national economic news, "5g is an epoch-making product, which will directly promote the formation of new industries and social forms. In fact, the industries that are spawned are & lsquo; intelligent alliance of all things", which will further promote the emergence of a new era. '

For China, 5g is no longer a future concept, but has been placed at the level of national strategy. In this year's report on the work of the government, Premier Li Keqiang specifically mentioned the importance of the fifth generation mobile communication technology (5g) for the future development of the country; in the 13th five year plan for national informatization, 5g was mentioned 16 times. This also shows that the high-level is willing to take the lead in 5g network technology in the world.

At the same time, the three operators have a positive attitude. It is reported that at present, the three major operators plan to achieve 5g network business in 2020. Take China Telecom for example. China Telecom announced on December 5 that its 5g base station in Lanzhou had been opened recently. So far, China Telecom has launched 5g pilot projects in xiong'an, Shenzhen, Shanghai, Suzhou, Chengdu, Lanzhou and other six cities and regions. The company said the 5g pilot project entered a new stage.

It is worth mentioning that at the recent World Internet Conference, there was a message that a complete set of 5g network equipment solutions for commercial use will be launched in 2018, and domestic manufacturers such as Huawei, Jinli, 360 and vivo are simultaneously developing and supporting 5g smart phones.

In addition, the Ministry of industry and information technology of China issued a notice in late November to officially launch the third phase of 5g technology R & D test, and strive to achieve the basic goal of the third phase of test by the end of next year.

Xiang Ligang, an expert in communication industry and CEO of Feixiang network, said in an interview with China national economic news that "the third stage of testing means that 5g network has the conditions to run tests in real situations, which is the last step towards commercialization of 5g network".

5g has risen to the level of national strategy. Operators, communication equipment field, Internet companies, etc. are constantly exploring and improving 5g applications. In terms of top-level layout, hardware facilities, investment capacity and market scale, 5g is undoubtedly the best in the world. "In the era of 2G and 3G, China is running with it. When 4G China is basically in sync with the world, 5g China is leading the way. There won't be much problem in entering 5g era first in the future," Wang said.

Xiang Ligang agreed that it is inevitable for China to lead 5g. According to the plan, trial commercial application will appear in 2019, and scale commercial application will be realized in 2020. By 2020, China's Congress will have the world's leading 5g application market. '

However, Liu Qicheng, a communications industry observer, said in an interview with China national economic news, "China is very advanced in 5g R & D and testing.". Whether China will be the first to enter the 5g era is not clear. '

He further pointed out that major countries in the world, especially Japan and South Korea, are also accelerating 5g testing and commercial time. It is reported that South Korea will carry out 5g 'pre commercial test' in 2018 to support the Pyeongchang Winter Olympics; Japanese mobile operators will accelerate the verification of key technologies and frequency band selection. However, the 2018 Pingchang Olympic Games is just around the corner. 5g technology is likely to be used in large-scale events in the first place.

'China is not necessarily the first country to enter the 5g era, but it is definitely the most mature and market-oriented country to enter the 5g era. Liu added.

Standards will be improved

It is worth mentioning that the first 3GPP 5g NSA version was officially frozen at the 3GPP packet conference recently concluded in Reno, USA. the freezing standard is the core standard of NSA (non independent Networking).

"The formal freeze of this version means that 5g is basically stable in the general theory of technology application, and the content of this version also makes a basic description for 5g technology application. In the future, based on this version, all parties can make continuous progress and improvement. "Said Xiang Ligang.

Liu Qicheng said: 'this standard is the first standard of 5g technology, indicating that 5g has a relative coordination at the technical level. 5g standard is unified in general, but different technical standards will appear due to different application scenarios. The first standard will be established, and the subsequent technical standards related to application scenarios will be accelerated. '

In fact, the United States, Europe, China, Japan, South Korea and other major countries and regions in the world are also competing for 5g standard to lead the industrial development.

In China, the development plan of information and communication industry (2016-2020) issued by the Ministry of industry and information technology clearly states that "5g standard research shall be carried out, and international standard formulation shall be actively participated in, becoming one of the leaders".

According to China's 5g planning steps, 5g standard research will be launched in 2016. It is expected that the first version of the standard will be completed in 2018, and then the start time of commercial application will be determined around 2020 according to the product maturity.

Industry insiders believe that China has been in the leading position in the world in terms of standard layout, and the gap between China and the world's earliest commercial time has also been shortened from 8 years in the 3G era and 4 years in the 4G era to 1 year.

It is worth mentioning that China Mobile, China Telecom, China Unicom, ZTE, Huawei and Datang Telecom have participated in the 5g standard formulation. According to the media, the total number of 5g proposals submitted by Chinese communication enterprises to 3GPP is about 40% of all proposals. At the same time, in each 5g working group, Chinese experts all occupy a large proportion and play an important role.

Xiang Ligang said: 'after 2G follow-up, 3G catch-up and 4G catch-up, China's communication industry is expected to surpass in the 5g era and gain a greater voice. '

In addition, analysts predict that for the future development of communication technology, ITU has more work to do in formulating more reports and suggestions, and the end of 5g standardization is likely to be by the end of 2019.

Huawei takes 5g standard and Huawei makes 5g standard

On November 17, 2016, the 87th meeting of 3GPP (wireless physical layer) was held in Las Vegas to discuss 5g short code scheme. The three protagonists are still Huawei's polarcode scheme, Qualcomm's LDPC scheme and France's turbo2.0 scheme. In the end, China's scheme won.

China's plan was selected into 5g (the fifth generation mobile phone mobile communication standard).

On November 17, the 87th meeting of 3GPP's RAN1 (wireless physical layer) was held in Las Vegas, USA to discuss 5g short code scheme. The three protagonists are still Huawei's polarcode scheme, Qualcomm's LDPC scheme and France's turbo2.0 scheme.

In the end, Huawei's polar scheme won the competition from two major competitors, LDPC in the United States and turbo2.0 in France, becoming the embB scene coding scheme of 5g control channel, while LDPC became the uplink and downlink short coding scheme of data channel. 5g short code coding scheme consists of data channel coding and control channel coding.

At the meeting held in Lisbon, Portugal on October 14 this year, the LDPC scheme of the United States was determined as the 5g medium and long code coding scheme.

It is reported that around the fight for 5g standard in the future, the two coding conferences have become the most fierce battle in the history of wireless communication, which can be described as a "war" without gunpowder.

The representatives of all parties come and go around their own plans, and they can't make concessions to each other. The meetings for several consecutive days have been discussed until the early morning of the next day, and the latest meeting actually lasts until 1:30 a.m.

According to industry insiders, in Lisbon conference, although Huawei has a large number of scheme supporters, the US LDPC scheme supported by more important manufacturers won in the end. LDPC is led by Qualcomm, behind which are giants such as Intel, Samsung, Nokia and Verizon. Behind Huawei's polar solution are more Chinese manufacturers, such as ZTE, Spreadtrum, Xiaomi, oppo, vivo, Alibaba, China Mobile, China Telecom, China Unicom, etc.

It is reported that after the failure of Lisbon conference, polar side made reflection and summary, adjusted the plan, and sent more than 50 representatives to the US Conference. So far, the 5g standard dispute has become a contest between China and the United States. Due to the lack of supporters in French scheme, turbo 2.0 encoding, which monopolizes 3G and 4G encoding, will go into history in the future.

Up to now, Huawei has kept a low profile and has not expressed any opinions on 5g short code results.

Coding and modulation is known as the crown of communication technology, which embodies the overall strength of a country's basic theory of communication science.

According to a professional communication website, the polar code is written by erdal, bilkent University in Turkey Professor Arikan first proposed in 2008, and his paper proved for the first time that in the binary input symmetric discrete memoryless channel, the polarization code can 'achieve' Shannon capacity, and has practical linear complexity coding and decoding ability.

According to the above report, the core of polarizing code construction is through the processing of 'channel polarization'. On the coding side, the coding method is used to make each subchannel show different reliability. When the code length continues to increase, one part of the channel will tend to the perfect channel with capacity close to 1 (error free code), the other part will tend to the pure noise channel with capacity close to 0, and the capacity is close to 0 Information is transmitted directly on the channel of 1 to approximate the channel capacity. On the decoding side, a simple successive interference cancellation decoding method can be used for the polarized channel to achieve the performance similar to the maximum natural decoding with lower complexity.

In the communication industry, the fight for standards is the fight for the highest voice. Once the standard is established, it will have a huge impact on the global communication industry.

Fu Liang, an independent Telecom analyst, said in an interview with surging journalists that the winner was the manifestation of years of R & D investment by Huawei and ZTE. In the future, more 5g technologies will have the shadow of Huawei and ZTE.

"The two companies have a certain say from the era of 2G cloning and imitation to the era of 3G. They actively participate in the era of 4G and lead in the era of 5g. "Fu Liang said that with the shadow of Chinese manufacturers in 5g standard, it would be ridiculous for the United States to repel Chinese telecom equipment in the future.
