Abstract: A method is provided for transmitting a configuration in a wireless communication system. A Base Station (BS) transmits the configuration for a discovery signal. The configuration indicates a periodicity and an offset of the discovery signal. The discovery signal is used to perform a measurement by a User Equipment (UE). The discovery signal includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Cell-specific Reference Signal (CRS), received within a predefined duration. The offset of the discovery signal is in a number of subframe(s). The predefined duration for transmitting all of the PSS, SSS, and CRS is set to 6 ms. The periodicity for transmitting all of the PSS, SSS, and CRS is set to 40 ms or 80 ms.
