Abstract: The present specification provides a method and UE for receiving configuration usable for a discovery, which can be used in a small cell scenario. In detail, the UE is configured for receiving measurement configuration for a discovery signal, wherein the discovery signal includes CRS, PSS, and SSS. The discovery may further include a channel status information-reference signal (CSI-RS) depending on a configuration of the CSI-RS. The measurement configuration may include at least one set of configuration elements. The UE performs a measurement on the discovery signal based on the received configuration. Further, the UE receives channel status information-reference signal (CSI-RS) configuration including at least one set of CSI-RS configuration elements used for a zero power CSI-RS, wherein the CSI-RS configuration includes at least one set of CSI-RS configuration elements, each set of CSI-RS configuration elements includes CSI-RS interval information and CSI-RS offset information.
