Abstract: The present specification provides a method for performing measurement by using an RSS in a wireless communication system. More specifically, the method performed by a terminal comprises the steps of: receiving, from a first base station, power boosting information indicating a relative value compared to cell-specific reference signal (CRS) power and CRS port information indicating the number of CRS antenna ports; receiving the RSS from the first base station; and measuring the reference signal received power (RSRP) and/or the reference signal received quality (RSRQ) of the RSS on the basis of the power boosting information and the CRS port information.

Abstract: The present specification provides a method for transmitting and receiving downlink control information (DCI) in a wireless communication system supporting narrow band-Internet of things (NB-IoT). Specifically, a terminal monitors at least one first candidate PDCCH in a first search space and at least one second candidate PDCCH in a second search space, wherein the first search space and the second search space may partially or entirely overlap each other on a time axis. Thereafter, the terminal may search for a first DCI in the at least one first candidate PDCCH and a second DCI in the at least one second candidate PDCCH, wherein the sum of the number of the at least one first candidate PDCCH and the number of the at least one second candidate PDCCH may be less than or equal to a specific number.

Abstract: The present disclosure provides a method for a terminal to receive a physical downlink shared channel (PDSCH) in a wireless communication system supporting a narrow band-internet of things (NB-IoT). Specifically, the terminal receives a first physical downlink control channel (PDCCH) including first downlink control information (DCI) from a base station and receives a first PDSCH on the basis of the first DCI. Here, the first PDSCH may include indication information indicating whether a multi transport block is scheduled. The terminal receives a plurality of PDSCHs from the base station, wherein at least one PDSCH of the plurality of PDSCHs may be received without receiving a separate DCI according to the indication information.

Abstract: Provided are a method for performing a random access process in an unlicensed band, and a device using the same. The device receives a random access preamble (RAP) order instructing the transmission of a RAP. The device performs a clear channel assessment (CCA) in an unlicensed cell during an RAP window so as to transmit the RAP when the device succeeds in CCA.
