Huawei is banned from an infrastructure point of view. Qualcomm does device chips for phones and whatnot, not network infrastructure.
The US government hasn't banned consumer devices of Huawei (except for government purchases). So you can still buy a Huawei phone or laptop.
Also, Qualcomm basically had a monopoly in the US due to patents applying to CDMA phone tech (it's why most phones had different SKUs in the US versus the rest of the world, as you effectively needed a Qualcomm chip to get on Verizon's or Sprint's networks.)
