    Abstract: One disclosure of the present specification provides a method for performing measurement based on discovery signals. The method may comprise the steps of: receiving, from cells, discovery signals based on cell-specific reference signals (CRSs); and performing measurement based on the CRS-based discovery signals for a predetermined measurement period. If a measurement bandwidth is six resource blocks (RBs), the predetermined measurement period can be determined by 5*the measurement occasion periodicity of the discovery signals. If the measurement bandwidth is 25 resource blocks (RBs), the predetermined measurement period can be determined by 3*the measurement occasion periodicity of the discovery signals. Also, the discovery signals can be received for a discovery signal occasion duration defined by N consecutive subframes.

    Abstract: A disclosure of the present specification provides a method for measuring an interference from a neighboring device. The method may performed by a device and comprise: measuring, by the device, an interference based on a reference signal from a neighboring device, which is served by a neighboring cell; and transmitting, by the device, a measurement report to a serving cell, the measurement report including a measured value of the interference. One or more steps of measuring the interference and transmitting the measurement report may be performed based on configuration information. The configuration information includes one or more of start information, end information, a timer or a threshold.

    Abstract: One disclosure of the present specification provides a method for receiving a discovery signal from a license assisted access (LAA) based cell operating in an unlicensed band. The method may be performed by a user equipment (UE) and comprise: receiving a discovery signal measurement timing configuration (DMTC) including information on a periodicity of the DMTC and information on an occasion duration of a discovery signal. Here, if the UE operate in a bandwidth of 10 Mhz, the occasion duration may include a first subframe and a second subframe. The method may comprise: performing a cell detection for the LAA based cell operating in the unlicensed band, on the first subframe of the occasion duration; and performing measurements for the LAA based cell operating in the unlicensed band, on the second subframe of the occasion duration.
