The present invention discloses a method for reducing inter-Femtocell interference, including: obtaining an average channel gain of all available channels; determining whether the average channel gain is greater than a preset threshold; if the average channel gain is greater than the preset threshold, determining, by using spectrum sensing, a P channel and an N channel, where the P channel is one or more available channels causing greatest interference and the N channel is one or more available channels suffering greatest interference; and transmitting or receiving a signal in an available channel other than the P channel and the N channel. An embodiment of the present invention further provides a corresponding Femtocell base station. With the technical solutions of the present invention, when the average channel gain of all available channels is greater than a preset threshold, the P channel and the N channel are determined and excluded, so that signals are transmitted or received only in other available channels. In this way, not only interference caused to other Femtocell base stations can be reduced, but also interference suffered from other Femtocell base stations can be reduced. |
