The present disclosure provides a method of performing a small cell detection, a small cell base station using the same method, and a mobile electronic device using the same method. The method and the device would perform functions including a user equipment (UE) detecting a discovery signal from a small cell base station (BS) over a schedulable resource in a Macro cell frequency, the user equipment transmitting a detection report to a Macro cell BS in response to detecting the discovery signal, the UE receiving a measurement command to measure a small cell BS in the small cell frequency, and generating and transmitting the measurement report after measuring the small cell BS in the small cell frequency.
