Abstract:
1. A method for controlling a small base station, comprising: determining whether the small base station is in a blank state; transmitting a deactivation request message to a macro base station if the small base station is in the blank state; operating the small base station in an inactive mode if a deactivation response message is received from the macro base station, the inactive mode being a mode of the small base station in which a synchronization channel or a minimal channel is transmitted to enable a terminal in a cell area of the small base station to identify the small base station; and operating the small base station in an active mode if a deactivation rejection message is received from the macro base station, the active mode being a mode of the small base station in which the small base station serves a terminal in the cell area of the small base station.
