With the development of science and technology, network information is also developing rapidly. From 1g, 2G in the first place a few years ago, to 5g in the present, but in the last month, the 5g incidents of Huawei brand have been one after another, and netizens are confused. What's the matter with Huawei and Qualcomm? 5g scheme Lenovo voted for Qualcomm.
At the latest 5g standard voting meeting, Lenovo voted for Huawei on short code, but Lenovo voted for Qualcomm on data code regardless of short code or long code. There are long and short codes for both control and data. Huawei's polarization code has no disadvantage in short code.
In the fierce competition for short code, Lenovo and Motorola also invested in Qualcomm! In the proposal to promote LDPC as the only coding scheme (long code + short code), Lenovo seems to be the only Chinese enterprise among all joint agencies.
ZTE and Huawei are also fierce in foreign countries, but ZTE still invested in Huawei. It's a pity that Huawei has got the control code. The short code of data channel is also a good opportunity for Huawei.
The control channel uses Huawei's main polar code. But LDPC and polar code are not monopolized by Qualcomm and Huawei. I don't know how many key patents each company has. But for Huawei, polar is better than LDPC.
The final structure is that according to the patent licensing plan given by Qualcomm, for example, if the price of a mobile phone is 1000 yuan, it needs to be paid to Qualcomm about 32.5 yuan, and the mobile phone market in China also has a huge volume of shipments, so the patent fee of Qualcomm will be full every year.
