Embodiments of the present disclosure relate to a device, method and computer readable storage medium for wireless data transmission. In example embodiments, the device includes a first NCO configured to shift a frequency of a pre-distorted downlink baseband signal by a first offset to generate a first signal. The baseband signal is associated with a plurality of allocated carriers. The device also includes an RF processing unit including an LO configured to generate an LO signal at an LO frequency. The LO frequency is within a protection area of one of the plurality of allocated carriers or equal to a center frequency of the one of the plurality of allocated carriers. The device also includes a power amplifier configured to generate, based on a modulated baseband signal, an amplified signal for transmission. The device also includes a second NCO configured to shift a frequency of the amplified signal by a second offset to generate a second signal for generation of a pre-distortion coefficient.
