It was just an example and as you suggest, probably not something they are interested in as Huawei was part of the 5G research. A better example might be amd64 acceleration architecture, or Nvidia's CUDA cores.
That said, these large companies are highly motivated to patent anything and everything the patent office will accept. It's a broken system anyway, but I can't suggest anything better.
The irony of Huawei or any Chinese manufacturer wanting to charge for use of patents is that they have grown by abusing the patents and trademarks of others. Apple for example lost the trademark fight over the use of 'iPhone', despite filing a trademark bid some 8 years prior [1].
