A base station (BS) circuitry, configured to adapt operation of a user equipment (UE) between a stand-alone operation mode and a mobile network operator (MNO) assisted operation mode, includes: a first interface connectable to an MNO network; a second interface connectable to the UE; and a BS controller, configured to: transmit a first register message via the first interface to the MNO network, wherein the first register message indicates a request to operate the UE in at least one licensed frequency band of the MNO network, and signal a hand-over via the second interface to the UE, wherein the hand-over indicates a transition from operating the UE in at least one frequency band of the stand-alone operation mode to operating the UE in the at least one licensed frequency band of the MNO assisted operation mode.
