Abstract
Disclosed is a method and a radio network node for compensating for local oscillator pulling or pushing. The method comprises determining, in a digital domain, a correction phase for the local oscillator to offset a phase error caused by the local oscillator pulling or pushing. The method also comprises correcting a phase of the baseband signal in the digital domain using the correction phase to compensate for the local oscillator pulling or pushing With the proposed method and radio network node, the phase error caused by the local oscillator pulling or pushing could be diminished due to phase correction in the digital domain.
