Are there criteria which determine whether UL B41 CA is active and that disable HPUE?
Is this determined by the network or on the device itself?
Or, will a device like the iPhone XS always have HPUE enabled, which disables UL B41 CA?
If I had to guess, I would say that it is likely that with a strong signal, B41 upload CA will be enabled and with a weak signal B41 upload CA will be disabled and HPUE will be enabled. That would give the best experience to the user.
