Abstract

The invention relates to a method for mitigating interference generated by a first access node covering a femto-cell on a first transmission channel established between a first mobile device and a second access node covering a macro-cell, the macro-cell overlapping the femto-cell, the method being run by the first access node and comprising the steps of: receiving a first parameter representing a pathloss of the first transmission channel, receiving a second parameter representing a pathloss of a second transmission channel established between a second mobile device and the first access node, choosing a frequency band among a frequency spectrum to be used for data transmission through the second transmission channel, based on the first and the second pathloss parameters, determining a transmission power for the frequency band to be used for data transmission through the second transmission channel.
