A method and apparatus for measuring inter-cell measurement in a wireless communication system are discussed. The method includes: receiving information regarding a predetermined resource region to which a sounding signal allocated for user equipments (UEs) connected to base stations (BSs) contained in the same coordinated cluster is transmitted, the sounding signal being used to detect a UE causing inter-cell interference; determining whether transmission of the sounding signal is granted for a serving UE in the predetermined resource region; and if transmission of the sounding signal is granted, transmitting a transmission grant message of the sounding signal to the serving UE, wherein whether the sounding signal transmission is granted is determined based on a random number, or is determined based on information of an available resource region of each BS if information regarding the available resource region of each BS is received with the information regarding the predetermined resource region.
