The method comprising measuring by an interfered base station (BS2) the uplink interference and when said uplink interference exceeds a given threshold performing a cancellation process by: discovering and identifying a serving base station (BS1) to which an interfering user device (UE1) is wirelessly connected; requesting to the serving (BS1) the RF fingerprints of the one or more interfering user devices served thereby and using the same frequency resource blocks (RB) of said interfered (BS2); receiving the RF fingerprint of said interfering user device (UE1); consulting said received RF fingerprint in a register; selecting the RF fingerprint more similar to the received one and taking the information of level of interference associated thereto; and using said taken level of interference information for performing said cancelling of said uplink interference.
