Abstract
Control unit within a femtocell base station is arranged to detect a transmission collision situation and resolves it by adjusting the timing of the transmission signal and consequently the frame position gradually over time. The adjustment (or shift) is performed in a slow enough rate such that the User Equipments currently connected (camped) to the femtocell base station remain connected. Additionally, a method is also provided. The method comprises: detecting neighboring base stations; detecting frame boundaries of the transmitting signal of each detected neighboring base station; calculating optimal transmit position; setting transmit position to calculated optimal transmit position; and maintaining optimal transmit position by gradually adjusting transmit position over time. In case, detecting neighboring base stations is not possible, the method comprises: detecting absolute time drifting in view of an absolute accurate time reference and maintaining constant absolute transmit position by gradually adjusting transmit position over time.
