16 May for Lenovo

Polling gate

The Beijing Commercial Daily reporter combed the specific circumstances of the voting.

In the process of 5G standardization of 3GPP, the decision on channel coding is made in two sessions. The first meeting was held in Lisbon in October 2016 with RAN 1 #86 bis. Only data channel coding in eMBB scenarios is fully discussed in this meeting. At the meeting, three data channel coding schemes were proposed, namely Qualcomm, Samsung, Alcatel-Lucent-Shanghai Bell and other companies such as LDPC and Huawei's main Polar code, as well as Ericsson and several Japanese companies recommended LDPC Turbo code portfolio. Lenovo chose to support LDPC for its own technical reserves and patents.

After the meeting,

The industry believes that these votes are deciding the direction of technology. Finally, the standard enterprises will receive more patent fees after 5G business.

As far as we know,

Internal letter


Liu Chuanzhi and Yang Yuanqing jointly issued the internal letter theme of "action, fight to win the battle of Lenovo honor". The letter points out that in the whole process of voting, the representatives of Lenovo Group follow two principles: one is the most basic principle, that is, to maintain the interests of their own enterprises; and a higher principle is to pay attention to the overall interests of the state and industry. After careful investigation and verification by all parties, Liu Chuanzhi thought that Lenovo's voting principle was not a problem and there was no problem in its implementation.

Liu Chuanzhi mentioned that, in the first round of voting on the 5G data channel scheme, Lenovo chose the LDPC technology scheme based on its own pre - technology and patent reserves. In the second round of voting, Lenovo took into account the overall industrial cooperation, innovation and development of the country, and chose the Polar code scheme that did not accumulate too much technology before the company.

It is noteworthy that the news that Lenovo and Motorola reversed the high pass - dominated LDPC code scheme in the data channel, leading to the HUAWEI dominated Polar code scheme to fall by two votes.

Industry insiders think that Lenovo's first vote on the long code of the data channel chose LDPC because Lenovo's Motorola has been in the LDPC direction before, so there are some patent reserves in hand, and the vote is in line with its own interests. But in fact, all companies support the LDPC scheme on data channel long codes. Lenovo and Motorola Mobile's two votes have no real impact on HUAWEI's Polar code's failure in the long channel data channel.

In the next data channel short code voting, Lenovo and Motorola voted for the Polar code on the vote, but the Polar code was finally defeated. In addition to the support on the short code of the data channel, Lenovo and Motorola also voted unreservedly on the Polar code scheme in the subsequent eMBB control channel coding scheme to help HUAWEI pull back a key set and become a coding scheme for the 5G eMBB control channel.

Analysts believe that Lenovo and Motorola should choose a LDPC code scheme on a short code scheme for data channels, as Lenovo and Motorola own more technology accumulation on the LDPC code, if only from the point of view of commercial interests. Against this background, Lenovo and Motorola still choose to support HUAWEI led Polar codes, in fact, to safeguard the overall interests of China's 5G industry.

Standard war

Lenovo's internal letter seems to be just a clarification of the enterprise, but as Liu Chuanzhi points out in the letter, an incident in the technical field was suddenly turned out and kept fermenting in the last two years. Is this an accident or is it being exploited by someone? One cannot help but think deeply.

In the industry, it does not exclude some self media self speculation behind this matter, but more important is the refraction of the 5G war between China and the United States and Europe. Kang Zhao, the chief editor of the world network of operators, believes that 2018 is an important node for 5G to enter international standards. The first edition of the 5G international standard will be released in June. This node will appear in the wind. It must be pushed behind the scenes, and it is a stakeholder.

According to Xiang Ligang, a senior communications expert, from the view of the overall industry ecology, the formulation of the global 5G standard depends largely on the competition and competition between the three party business camps in China and the United States and Europe. At present, the strength of the three party is in a state of roughly balance. If the outcome surface of the Chinese 5G enterprise group is disrupted by the interference of external forces and false information, it is likely to break the balance and lead to a very unfavorable position in the 5G standard setting of Chinese enterprises.

It is reported that due to the early development of research and development, and the formation of a wide range of industrial cooperation, the current domestic 5G technology level in many fields and foreign enterprises are different, and even in some key technologies, it has obvious advantages. From the assessment of the former international organizations, our country has already possessed the ability to make the 5G standard.

A US study of the results released earlier showed that China was slightly ahead of Korea and the United States in developing the 5G competition. The US based CTIA, a wireless network operator Industry Association, shows that the United States has fallen behind the deployment of the ultra high speed wireless network systems needed for autopilot, telemedicine and other technologies.

It is reported that, in this wave, the Polar code proposed by the HUAWEI lead force has become the control channel coding for the 5G eMBB (the enhanced mobile broadband, the main application scene is the 3D/ ultra high definition video and other large traffic mobile broadband services) scenes. 3GPP plans to announce the first standard specification of 5G in June this year. The communication standard involves different scenarios and different channels, and will involve multiple technical solutions.
