Abstract

Disclosed are a method and an apparatus for finding small cells. The method comprises: a base station of a macrocell triggering small cells in a non -activated state to send specific signals, and triggering a user equipment (UE) to receive the specific signals sent by the small cells; the base station receiving information of small cells found and determined to be reported by the UE according to the received specific signals; the base station selecting a part or all of small cells determined by the UE, and configuring the selected small cells to quasi- serving small cells of the UE. Through the present invention , in a heterogeneous network of a wireless communication system, the UE in the macrocell can find the small cells subordinate to the macrocell and the network side can select appropriate small cells to provide services for the UE; moreover, the mechanism of the present invention ensures effectiveness and energy saving of both the network side and the UE.
