Abstract

The present invention relates to a femtocell search method for a handover from a macrocell to a femtocell. The present invention relates to a method for a terminal that accesses a macrocell to search a femtocell in an environment where a plurality of femtocells are overlapped in one macrocell. The terminal searches a femtocell by using a dummy preamble in order to minimize the size of neighbor cell lists broadcasted from the macrocell to the terminal. Therefore, according to the present invention, an MAC overhead can be minimized by eliminating neighbor femtocell lists in a mobile neighbor advertisement (MOB_NBR_ADV) message broadcasted from the macrocell, and the terminal can search a femtocell with a minimum scanning load by checking only a femtocell dummy preamble in a dedicated symbol of the macrocell.
