Also, I doubt that the US is going to completely ban Huawei from procuring American components. Keep in mind that Huawei's products are the backbone of many ISPs in the EU. A total ban is going to severely hamper many services in the EU causing significant political backlashes. Unless, the US just totally don't give a damn about its allies.
This was a big warning to the EU from the US. You don't obey us? We'll force it down your throat.
The Bloomberg article also mentions this:
Huawei’s base station, smartphone, server and maritime cable businesses simply cannot run without Qualcomm baseband and processor chips. There are alternatives -- but from American peers such as Intel Corp., Micron and Broadcom Corp.
狗急跳墙
But in base stations, the central (the most important) chip is FPGA.
For smartphones, this is not true. Huawei is not totally dependent on Qualcomm. When you read an article from Bloomberg, New York Times, etc., you should beware of fake news.
.
"The two largest smart phone makers in the world supply a majority of their own modem chips to help their devices connect to wireless data networks, according to evidence presented at an antitrust trial for chip supplier Qualcomm Inc"
I don't know about base stations, but I think it's unlikely that Huawei would rely on a rival for a key part of the 5G network.
