Hi ansy1968,
That polar coding, the idea or theory, not sure if that can be patented, although we hear stories that Apple tries to patent the number 5 for instance, but that gets thrown out.
It probably could is my guess bro, and anyone who uses it has to pay a royalty.
Huawei patented all their work with the equipment using the polar coding is what I believe the article is saying. That would presumably be the reason why Huawei has that big lead over the rival telecom makers, and why we always hear about that the rivals must pay Huawei for use of these patents for 5G.
Either they pay Huawei for the use of their breakthroughs (patents), or try to engineer their own. So far it does not seem that Ericsson has done that yet, if ever. Nokia not in the game.
The other point of that article that was interesting was the standards body and that meeting in Las Vegas. That deadlock, the Chinese were prepared to say get lost and they would have went their own way. The world separating into two technology blocks was a lot closer than anyone thought. It would have been USA one side, and China the other side, and everyone in the middle could choose what they would like to do, use both sides or pick one side.
Huawei took to the idea, and out innovated everyone. Something they decided not to emphasize much in the article, their audience would not like that.
What was funny too, was the Canadian connection, and how those engineers from the bankrupt Northern Telecom company played a big role in all of this, who probably were mostly Chinese people in that team.
