At the 86th meeting in June, 20 16, all parties voted on the scheme of using long codes for data channels. In this vote, only Huawei supported the full adoption of Polar, most China manufacturers chose to support the adoption of LDPC+Polar, while Lenovo and its Motorola Mobility chose to support the full adoption of LDPC, which became the origin of this round of questioning. According to industry analysts, at the technical level, the 5G data channel pursues the transmission rate, mainly large data packets, which is the performance advantage of LDPC. He also mentioned that Lenovo was recently kicked out of the Hang Seng Index. According to research institutions, Lenovo has fallen behind. According to the "20 17 China Smartphone Market Research Report" released by GFK, Lenovo ranked at the bottom of the China 10 smartphone market last year, with a market share of only 0.4%.
The company is fighting for its own interests, not for the interests of the country. Therefore, the camps in 3GPP are mainly formed according to vendor types, because they have more common interests. How absurd it is to accuse Lenovo of betraying the so-called "China camp". Big companies bet on both sides. Supporting LDPC does not necessarily mean supporting Qualcomm against Huawei.
According to an industry insider, these votes determine the direction of technology, and the enterprises that are finally selected as standards will get more patent fees after 5G commercialization. If only from the point of view of commercial interests, Lenovo and Motorola should also choose the LDPC code scheme in the short code scheme of data channel, because Lenovo and Motorola have more technical accumulation in LDPC codes themselves. In this context, Lenovo and Motorola still choose to support Huawei-led Polar code, in fact, in order to safeguard the overall interests of China's 5G industry. Behind this incident, there are some suspicions of self-promotion from the media, but more importantly, it reflects the 5G war between China, the United States and Europe. Behind Lenovo's being wronged, it is actually a provocation to China's corporate relations. 20 18 is an important node for 5G to enter international standards. The first version of the 5G international standard will be released in June. There is a storm at this node, which must be behind the scenes and a stakeholder.
