1. A method performed by an apparatus for handling signals in an Orthogonal Frequency Division Multiplex (OFDM)-based communication network received at a receiver, the method comprising:
obtaining a signal in time domain, the signal comprising a payload signal sent from a transmitter towards the receiver as well as an interference signal, the payload signal residing in a first frequency band and the interference signal residing in a second frequency band outside the first frequency band;
separating the payload signal from the interference signal using a filter, and
processing the separated payload signal with a first time window, or processing the separated interference signal with a second time window, or processing both the separated payload signal with a first time window and the obtained signal with a second time window, each time window being substantially an OFDM symbol wide, so as to achieve an output signal or first output signal comprising the payload signal and a time-windowed interference signal and/or to achieve a second output signal comprising the interference signal and a time-windowed payload signal,
wherein the processing with the first time window and/or the second time window comprises, for each time window, a connecting time during which a window function for the time window increases from 0 to 1, a steady time during which the window function is 1 and a disconnecting time during which the window function decreases from 1 to 0, and wherein the separating using a filter and the processing is only performed during the connecting time and the disconnecting time.
