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.

Abstract: The present disclosure provides a method for receiving, by a terminal, a channel state information-reference signal (CSI-RS) in an unlicensed band. Particularly, the disclosure comprises: receiving CSI-RS resource information for receiving the CSI-RS and information relating to a first bandwidth allocated for the CSI-RS; and receiving the CSI-RS through CSI-RS resources included in at least one second bandwidth among multiple second bandwidths included in the first bandwidth, wherein the at least second bandwidth is determined on the basis of clear channel assessment (CCA) for each of the multiple second bandwidths.

Abstract: The present disclosure relates to a method and device for receiving a paging signal in a radio resource control (RRC) connected mode. More specifically, the present disclosure relates to a method and a device therefor, the method comprising the steps of: receiving gap configuration information indicating a gap section in a search space; when a first search space related to a data signal in a specific time interval and a second search space related to the paging signal are configured in different narrowbands (NBs), monitoring the second search space in the specific time interval, wherein the first search space is not monitored in the specific time interval on the basis of the gap section; and when the first search space and the second search space are configured in one NB in the specific time interval, monitoring the first search space and the second search space in the specific time interval without applying the gap section.
