That communication happens usually through a "dumb" serial-like connection to the LTE modem. All of the modem commands are handled in userspace, the kernel doesn't care about anything relating to this at all (and it really shouldn't). > What I fear more is that everything related to LTE is inside the > closed device firmware, and data is sent from the TC layer into this > black-box firmware through a sort of API.

Look at the Android AOSP images for the location for most of this logic, there should be a Telephony HAL somewhere in there that handles the heavy-lifting of all of this logic.
