Although a year and a half of the vote has passed, the voting process for the 5G short code solution in the 3GPP RAN 187 meeting has been dug out several 'versions'. As for 'Why is Lenovo not voting for Huawei?', Lenovo does not support it. Polar program ', 'Lenovo station Qualcomm, led Huawei to lose with a narrow gap' and other articles were then swept in the major platforms.
After questioning whether 'Tencent had any dreams', Lenovo was once again the object of everyone's torture. However, under the constant trade friction between China and the United States, it has to be said that some posts actually do have some personal emotions. The people criticized that professionalism and rigorousness were taken as transparent. 3GPP decided to go through repeated discussions and rigorous review to ensure its attainability in deciding each technical standard. It was not like 'village officials pulling votes', a rigorous technical topic. A hat was hardened and cast a shadow.
Huawei also issued a clarification statement, stating that 'For the Polar code as a control channel encoding mechanism, Lenovo and its Motorola mobile all vote in favor of the proposal. Mobile communications is an open industry and requires all parties in the industry to work together.'
From the perspective of technology itself, channel coding technology is one of the core technologies behind 5G. It includes millimeter-wave technology (the base of 10G transmission rate), frame format (key for low latency), and multiple access (support Intensive scenes), channel coding (channel sub-control channels and data channels, coding again divided into short codes, medium-long codes) and data coding.
At the time, Huawei's Polar code competitor mainly consisted of Qualcomm-led LDPC coding and France-dominated Turbo2.0 coding. The two camps represented the leading forces in 3G and 4G technologies. Communication technologies include CDMA2000, WCDMA, and TD-SCDMA. The first two occupy the largest market, Europe, the United States, and Japan are the main technology-dominating countries. And, whether it is 3G or 4G technologies, Qualcomm has always been in a dominant position in standard setting.
Although the voting records could not be found, from the public information point of view, LDPC as a long-code part of the data channel all manufacturers have reached a consensus, leaving only a short code to be determined. The Internet circulated the so-called two key due to Lenovo and Motorola The defeat of Huawei's long code or the winning of the LDPC long code is purely nonsense. At the same time, due to the insufficient voting weight of the Polar camp, coupled with the opposition of companies such as Qualcomm, Samsung, and Ericsson, the final meeting decided on the data channel. Short codes also use LDPC, consistent with long codes.
In the 5G mobile broadband control channel, since the amount of data transmitted by itself is small, and reliability is more important than speed, it is exactly the advantage of the Polar code that Huawei's proposed Polar code becomes a proposal for a control channel coding scheme.
Some insiders of Huawei stated that this coding dispute is more of a technological dispute. LDPC becomes a data code, and Polar has become a control code, and it has technical advantages.
The development of communication technology standards has always been a contestable position for companies with R&D strength in the industry. There are such words: First-rate companies do standards, Second-rate companies do brands, Third-rate companies do manufacturing. It can be seen that in 3GPP, the Chinese are the key There are more than 30 positions, voting power exceeds 23%, contributions account for 30% of the total, lead projects account for 40% of the total, and can occupy a considerable amount of power; 5G core network standards are also led by Chinese companies, June 2017 The 3GPP confirmed that the 5G core network will adopt the SBA architecture proposed by 26 companies such as China Mobile and Huawei.
It must be said that from 3G to 4G to 5G, Chinese companies from backwards to parallel pursuits to the current echelon of the standards organization are actually 'emotional'.
But the more this time, the more afraid of 'holding and killing'.
Although Chinese companies have won the final solution for the control channel eMBB scenario coding, this does not mean that Huawei will be able to completely roll out Qualcomm. It does not mean that China has surpassed the United States in the field of communications technology. In fact, it is implementing 5G technology. On the other hand, Huawei and domestic companies still have a long way to go. Huawei's eMBB is just one of the scenarios for 5G applications. The other two scenarios still require another technical battle in the international arena.
In terms of the number of 4G core patents, the United States is still ahead of China. Although the distance on 5G is shrinking, it does not mean that companies already have a 'ultimate weapon'. Under the background of the increasingly visible globalization and cooperation, enterprises and enterprises The relationship between the state and the country has become increasingly close, cooperation has become the theme, and the strong should learn to be tolerant and compromised.
Finally, beginning in 1998, the 3GPP standards organizations consisting of major countries in the world, telecommunications, and communications vendors are a collaborative platform for all parties. Under the differences of business, politics and technology, it is believed that the volume of technology will be even greater on this platform. It's time to take seriously. At this time, holding Huawei in a one-sided manner and depreciating Lenovo is not a smart move for China's 5G development.
