Abstract
This disclosure relates to a baseband processor for processing down-converted and quantized radio frequency, RF, signals of an RF transceiver in baseband, wherein the baseband processor is configured to: detect an RF operation mode switching of the RF transceiver, and initiate a change of a voltage setting and an associated system clock rate of the baseband processor based on detecting the operation mode switching of the RF transceiver.

- initiate a change of a voltage setting and an associated system clock rate of the baseband processor based on the RF operation mode switching of the RF transceiver comprising the BWP configuration switching;
- adapt interference mitigation algorithms processed by the baseband processor based on the BWP configuration switching;
- and
- disable the interference mitigation algorithms when the BWP is switched to a new BWP having a different central carrier frequency so that the new BWP suffers reduced interference from adjacent bands.
