    Abstract: The present invention relates to a method for performing a random access process in a wireless communication system, and a device therefor, and relates to a method and a device therefor, the method comprising the steps of: receiving, from a base station, narrowband physical random access channel (NPRACH) configuration information; and repeatedly transmitting an NPRACH preamble on the basis of the received NPRACH configuration information, wherein, if a time gap between a completion time point of the last repeated transmission of the NPRACH preamble and a next subframe is smaller than a guard time, the last repeated transmission of the NPRACH preamble is dropped, or is punctured as much as the difference between the guard time and the time gap in the last repeated transmission of the NPRACH preamble.
