    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.

    Abstract: A terminal is disclosed by the present specification. The terminal may comprise: an antenna; a diplexer for compounding a carrier of a first band and a carrier of a second band and for connecting or disconnecting the same to the antenna; a filter connected to the diplexer, a first duplexer connected to the filter for separating transmissions and receptions in the carrier of the first band; and a second duplexer connected to the diplexer for separating transmissions and receptions in the carrier of the second band. To this end, the filter can eliminate harmonic components and intermodulation distortions (IMD) that occur when transmission in the carrier of the first band and transmission in the carrier of the second band are simultaneously performed.

    Abstract: According to one embodiment of the present specification, provided is a method for measuring a position in a wireless communication system. The method for measuring a position comprises the steps of: receiving observed time difference of arrival (OTDOA) assistance data from a positioning server; increasing an FFT sampling size when the value of a bandwidth of a positioning reference signal (PRS) included in the OTDOA assistance data is less than a first value; processing a plurality of received PRSs through the increased FFT sampling size; and calculating a reference signal time difference (RSTD) between the plurality of received PRSs.
