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.

Abstract: A method is provided for performing discovery signal measurements. A user equipment (UE) receives measurement configuration information including a sub-frame offset. The sub-frame offset indicates an offset between a secondary synchronization signal (SSS) and a channel-state information reference signal (CSI-RS) in a discovery signal. The sub-frame offset has a maximum value of four (4). The UE determines a sub-frame for the SSS in the discovery signal, and determines a sub-frame for the CSI-RS based on the sub-frame offset and the sub-frame for the SSS in the discovery signal. The UE performs a measurement on the discovery signal based on the CSI-RS.

Abstract: There is a provided a method for deciding transmission power to securely transmit data, the method comprising: determining a transmission rate toward an intended receiver, based on an upper limit of a decoding error probability of the intended receiver and a lower limit of a decoding error probability of an unwanted over hearer; and deciding a transmission power toward the intended receiver based on the upper limit and the lower limit. Here, if the upper limit is lower than the lower limit, the transmission toward the intended receiver is not performed.
