Claim:
1. A method in which a terminal measures Radio Resource Management (RRM) in an environment in which a macrocell and a plurality of small cells exist, the method comprising: receiving a discovery signal from a first small cell adjacent to the terminal among the plurality of small cells; measuring, when the first small cell is in a predetermined state, RRM of the first small cell based on the discovery signal; and receiving a measurement subframe bit pattern representing a measurement subframe in which the terminal can measure RRM based on the discovery signal and a non-measurement subframe in which the terminal cannot measure RRM from a serving cell, wherein the predetermined state comprises a first state in which the first small cell can transmit other signals in addition to the discovery signal and a second state in which the first small cell can transmit only the discovery signal.
