Abstract
Systems and methods are described for reducing an interference level associated with frequency drift in a wireless base station. The base station monitors an interference level in a frequency resource caused by a first frequency resource colliding with a second frequency resource. If the interference level is outside of an expected range, the base station adjusts a parameter of the base station such as a reference oscillator frequency to compensate for frequency drift. This method may be used in a femtocell wireless base station.
