Does Huawei have its own baseband? Why does Huawei honor the 7-baseband gate?

Because the patent of cdma is in Qualcomm's hand, if it is expensive to buy a baseband separately, Qualcomm does not want Huawei to have its own core, so the baseband price is very high. However, Huawei does not want to buy a cpu from Qualcomm, so it has to look for VIA's baseband, but VIA's baseband has fallen behind in research and development, so Huawei has to stubbornly use it, so there is a power consumption gate incident, but later it is said that this is just a friend in the dark, and there is no such door at all.
