A method for cancelling uplink interference in a wireless network, comprising: - measuring, by an interfered base station, the uplink interference provoked over at least one interfered user device wirelessly connected thereto; and - cancelling, by said interfered base station, said uplink interference by performing a cancellation process, characterized in that said cancellation process is performed upon said uplink interference exceeding a given threshold and comprises the following steps: a) discovering and identifying at least one serving base station to which at least one interfering user device of a plurality of interfering user devices is wirelessly connected; b) requesting to said at least one discovered and identified serving base station the RF fingerprints of the one or more interfering user devices served thereby and using the same frequency resource blocks of said interfered base station, the RF fingerprints being stored and including a measure of the complex frequency response of the radio channel between the one or more interfering user devices and the base station c) receiving, as a result of said requesting, at least the RF fingerprint of said at least one interfering user device; d) consulting said received RF fingerprint in a register which includes information regarding several RF fingerprints of other user devices and at least information regarding the level of interference caused on said interference base station when not being served thereby; e) selecting as a result of said consulting the RF fingerprint more similar to the received one and taking the information of level of interference associated thereto; and f) using said taken level of interference information for performing said cancelling of said uplink interference. - measuring, by an interfered base station, the uplink interference provoked over at least one interfered user device wirelessly connected thereto; and - cancelling, by said interfered base station, said uplink interference by performing a cancellation process, a) discovering and identifying at least one serving base station to which at least one interfering user device of a plurality of interfering user devices is wirelessly connected; b) requesting to said at least one discovered and identified serving base station the RF fingerprints of the one or more interfering user devices served thereby and using the same frequency resource blocks of said interfered base station, the RF fingerprints being stored and including a measure of the complex frequency response of the radio channel between the one or more interfering user devices and the base station c) receiving, as a result of said requesting, at least the RF fingerprint of said at least one interfering user device; d) consulting said received RF fingerprint in a register which includes information regarding several RF fingerprints of other user devices and at least information regarding the level of interference caused on said interference base station when not being served thereby; e) selecting as a result of said consulting the RF fingerprint more similar to the received one and taking the information of level of interference associated thereto; and f) using said taken level of interference information for performing said cancelling of said uplink interference.
