Recently, the attitude of voting Lenovo of the 5G standard Polar program triggered a war of words. It was reported that Lenovo voted against Huawei's China-led Polar solution and voted for Qualcomm. Therefore, netizens in China believe that Lenovo's behavior is tantamount to selling countries. ,Is this really true?
The cause of the incident was yesterday night, the online social platform continued to appear "Why does Lenovo not vote for Huawei", "Lenovo does not support Polar solution", "because Lenovo station team Qualcomm, eventually led to Huawei to lose with a weak gap." and other content posts.
In this regard, Lenovo CMO Wang Chuandong told NetEase that Lenovo voted for the 5G standard Polar solution (which is dominated by Chinese companies such as Huawei and China Mobile), including Lenovo's Motorola Mobile, which voted in favor.
At the 3GPP (GeneraTIon Partnership Project) voting conference on 5G standards, Lenovo voted for the 5G standard Polar solution (which is dominated by Chinese companies such as Huawei and China Mobile), including Lenovo’s Motorola Mobility. Is the vote in favor.
We condemn any rumors and also urge everyone not to believe in rumors. For malicious rumors, we retain relevant legal rights and pursue them in accordance with the law.
All along, Lenovo has been very supportive of the development of China's 5G technology, and will continue to work hard to promote the development of 5G technology and related products.
Unicom 5G voting truthIn fact, this is not something that happened recently, but at a 5G seminar held by 3GPP in November 2016.
In the discussion of the 5G short-code scheme called "3GPP RAN1 87 conferences", Huawei's Polar Code scheme finally won (to defeat Qualcomm's LDPC code) and became the final solution for 5G control channel eMBB scene coding. .
3GPP is an international organization that aims to develop globally applicable technical specifications and technical reports for communication systems. From 2G, 3G, 4G, to 5G to be opened, each generation network has corresponding technical standards and specifications. Usually, the research discussion of technical standards will last for a certain period of time, so you will see the words "87 meetings" and the problem will appear here.
According to the netizens of the online social platform, the coding scheme was determined twice. It was held in October 2016 in Lisbon, Portugal (86 meetings), mainly to determine the data encoding (divided into long code and short code). Another time was in the United States in November (87 meetings).
According to a company that participated in 87 meetings at that time, it was revealed to Tencent’s “First Line†that the voting on the technical plan was based on the issues raised at the previous meeting. Before the vote, everyone would prepare their own plans, or they could join the company in 87 meetings. Mainly the voting of the short code of the data channel. â€
As mentioned above, Huawei won the short-code control channel, and Lenovo did vote for it as stated in the statement. However, at the 86th meeting, Lenovo opposed the Huawei program, and it can be said that it voted against it.
"The 86 meetings were mainly to determine the data encoding, but in the end only the LDPC scheme for long codes was determined. The short code scheme did not reach an agreement at the time and stayed at the 87th meeting," the source said. Netizens from the online social platform also said, "At 86 meetings, Lenovo supports data channel coding using LDPC regardless of the code length, against Huawei's short code Polar solution." Subsequently, the netizen also listed the minutes of the meeting. . Tencent's "First Line" was also confirmed by a company that participated in 86 meetings.
However, if we look at the final results of the 87 meeting, Lenovo still invested in Huawei's short code program.
As for the short code or the long code, there are advantages in theory. The important significance behind this is that Chinese companies can resist foreign courts in the key technical standards of the network, and they will no longer be subject to people in the future.
“Determining what is the final end of a technical solution? There can be no political or commercial considerations, but more is driven by technology. How to better promote the development of the industry. This time it can be support, next time it can be Opposition, this is normal in technical discussions."
According to the 3GPP's plan, it plans to announce the first standard specification of 5G in June this year.
