* Note: IRadio 1.3 is an intermediate layer between Android P and Android Q. It's specifically
* designed for CBRS related interfaces. All other interfaces for Q are added in IRadio 1.4.
*
* This interface is used by telephony and telecom to talk to cellular radio.
* All the functions have minimum one parameter:
* serial: which corresponds to serial no. of request. Serial numbers must only be memorized for the
* duration of a method call. If clients provide colliding serials (including passing the same
* serial to different methods), multiple responses (one for each method call) must still be served.
* setResponseFunctions must work with @1.1::IRadioResponse and @1.1::IRadioIndication.
