Abstract: A semiconductor device including processing circuitry configured to determine a carrier band and reference signal bands based on a data signal received from a network, the carrier band and reference signal bands being allocated by the network, the reference signal bands corresponding to a reference signal for channel estimation, and the reference signal being within a carrier band, and output a control signal causing a local oscillator (LO) to change a LO frequency to a value that does not overlap the reference signal bands.
