Abstract

In one embodiment, a method of mitigating uplink inter-carrier interference (ICI) from macrocell mobile stations at a dedicated channel femtocell base station is provided that includes: determining a timing offset for a femtocell uplink symbol timing that reduces the ICI based upon an expected spatial distribution for the macrocell mobile stations with respect to the femtocell base station; communicating the timing offset to at least one femtocell mobile station; and at the femtocell base station, receiving an uplink symbol transmission from the at least one femtocell mobile station according to the timing offset.
