INTER-CARRIER INTERFERENCE MANAGEMENT IN DEDICATED-CHANNEL FEMTOCELL NETWORKS

摘要

PROBLEM TO BE SOLVED: To mitigate uplink inter-carrier interference (ICI) from macrocell mobile stations at a dedicated-channel femtocell base station.;SOLUTION: There is provided a method 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 transmitted from the at least one femtocell mobile station according to the timing offset.;COPYRIGHT: (C)2012,JPO&INPIT
