Huawei, praised by the media, is in distress. China does not have the final say on 5G standards.

Last weekend, " China sets the world's 5G technology standards! " , " Huawei crushes Qualcomm and wins the 5G era! " , " China's 5G completely ends Western standards " and other news about 5G have ignited the enthusiasm of many people. For a time, many people were crazy about swiping their friends' screens. What is the reason for netizens to " praise and kill " regardless of anything ? In the early morning of November 17th , US time , in the discussion of the 5G short code solution at the 3GPPRAN 187th meeting , the PolarCode channel coding solution recommended by China's Huawei stood out and became the final solution for the 5G short code control channel. The data channel coding solution of the short code uses the LDPC code promoted by Qualcomm in the United States . The 5G concept sector is almost all red. This news also made the capital level " crazy " . In the first two trading days of this week, 5G concept stocks broke out across the board, and the concept sector was almost all red. Research reports released by many securities firms are optimistic about communication companies. CITIC Construction Securities' research report believes that in the electronics field, there are investment opportunities in antennas, filters, IoT hardware, etc., and antennas and RF devices will benefit most directly. Ping An Securities recommends that investors give priority to baseband chip manufacturers Huawei HiSilicon and Spreadtrum Communications, and A -share listed companies pay attention to ZTE and Datang Telecom, which have communication chip R&D capabilities, and pay attention to equipment manufacturers FiberHome Communications and Xinwei Group. What exactly is the Polar code? What is its connection with 5G ? Is this screen-sweeping hype by Huawei? Or is it the enthusiasm of the melon-eating crowd? The China News Service Jingwei client will decipher it for you one by one. Huawei is very distressed by the excessive " praise and killing " of the protagonist by the self-media " self-media exaggerates the facts, which is inaccurate and not based on facts. " When the China News Service Jingwei client contacted the head of Huawei's media liaison department, she was the first to say. The person in charge also revealed that Huawei is just one of the companies that innovated and promoted the Polar code, not Huawei alone. Huawei Technologies Co., Ltd. @ 吴醒峰 also said that in the discussion about Polar code in recent days , many self-media did not understand the situation and turned it into another voice: " Huawei crushes Qualcomm " , " takes over the 5G era " , etc. In fact, Huawei itself did not focus on this.

Huawei Company News and Announcements

The author found on Huawei's official website that an announcement " 3GPP determines Polar code as 5G control channel coding scheme" was issued on the 19th, while the time for determining the scheme was the early morning of November 17th , local time in the United States ( that is, the evening of November 17th , Beijing time ) . Since the 18th , there have been public accounts such as "5G standard determined by China! " " Huawei crushes Qualcomm " , which indirectly confirm the statement of Huawei employees. In addition, in Huawei's news announcement of less than 500 words, the title did not mention Huawei, the wording in the article was modest, and Huawei's contribution was not mentioned many times. The " exaggerated " reports of self-media have caused " trouble " to Huawei . Huawei's person in charge said, " Today's public opinion is not conducive to Huawei and Chinese companies' future progress in promoting 5G , and there will even be resistance from foreign governments. " Member of the Science Squirrel Club, Weibo real-name user @ 奥克姆稀刀 believes that the greatest significance of Huawei's Polar code scheme becoming the 5G international standard is not in itself, but in the positive encouragement and recognition of the people. When China's WAPI became an international standard more than 10 years ago , it attracted ridicule and disdain from the whole society, who believed that the standards led by China were not good and the standards led by the United States were more reliable. Now the national spirit has been completely renewed. " Game " chose Huawei? When Huawei was flooding the circle of friends, Qualcomm was also frequently mentioned. What is the connection between them? According to data from the "First Financial Daily", Qualcomm once had a 100% domestic market share in its CDMA , WCDMA and LTE wireless communication standard essential patent portfolio ; the market share of CDMA , WCDMA and LTE wireless communication terminal baseband chips also exceeded 50% , with an absolute market dominance. It can be seen that Qualcomm has an absolute voice. According to previous media reports, when the 3G standard was formulated, the United States and South Korea led CDMA2000 and Europe promoted WCDMA . The two sides argued endlessly, giving China's TD-SCDMA an opportunity to become one of the 3G standards. When the 4G standard was formulated , Qualcomm and Intel were fighting each other, resulting in the failure of the two standards advocated by the United States to become the 4G standard. In the end, China's TD-LTE stood out. From the 3GPPRAN187 meeting, the Polar code recommended by Huawei was selected as the coding scheme for the control channel in the 5G control channel eMBB scenario, while the uplink and downlink short code schemes of the data channel belonged to Qualcomm LDPC code. Obviously, it does not match the " crushing Qualcomm " described by the self-media , and can only be said to be evenly matched. However, Fang Xingdong, dean of the International Internet Research Institute of Shantou University, believes that there is another mystery in the arrangement of the Polar code recommended by Huawei. On the one hand, this choice is a need for the game of industry interests. Everyone hopes to avoid Qualcomm's dominance; on the other hand, it is also to avoid China starting a new business again.

















Independent telecom analyst Fu Liang also believes that the decision to use the Polar code standard is the result of global compromise and mutual game. When will China have the final say? " Coding is really only a small part of 5G , " said the head of Huawei's media liaison department. Her statement was also recognized by independent telecom analyst Fu Liang, "3GPP defines three major scenarios for 5G : eMBB ( enhanced mobile broadband, corresponding to high-traffic mobile broadband services such as 3D/ ultra-high-definition video ) , mMTC ( large-connection Internet of Things, corresponding to large-scale Internet of Things services ) and URLLC ( low-latency, high-reliability communication, corresponding to unmanned driving, industrial automation and other services that require low-latency, high-reliability connections ) . These scenarios correspond to 5G 's AR , VR , Internet of Vehicles, large-scale Internet of Things, high-definition video and other applications. " Previously, at this year's first Global 5G Conference, the unified standard in the 5G era became a unanimous call from all walks of life. SATOH , chairman of Japan's 5GMF, said that global unified frequency bands are very important and are also the most efficient way to promote the development of 5G . Because of this, the Polar code recommended by Huawei as the 5G standard code has another meaning, that is, the " Chinese voice " in the global discourse power . In fact, the manufacturers that mainly promote and support the Polar code are not only Huawei, but also Chinese manufacturers such as ZTE, FiberHome, Datang, China Mobile, China Telecom, China Unicom, Acer, Hytera, Lenovo, etc. According to Fu Liang, the main manufacturers have made large initial investments in the hardware and software implementation of the coding scheme, and have a first-mover advantage, which will help manufacturers to take the lead in patent licensing and product performance, and related supporting manufacturers can also benefit from it. However, he also said that the eMBB scenario has just been determined, and the mMTC and URLLC standards must be determined before 2018 , when the game will really begin. Fang Xingdong believes that in the 4G era, the domestic market was in a state of time, place and people. In the 5G era, it is necessary to stand in the global pattern and face the direct challenges of major old giants. The 5G standard dispute is of course an important commanding height for countries to compete. In the competition of comprehensive technical strength and industrial competitiveness, a short code standard is just the tip of the iceberg. It deserves applause, but we should not be blinded by it.
