1. A method for performing a random access procedure by a user equipment in a wireless communication system, the method comprising:receiving narrowband physical random access channel (NPRACH) configuration information from a base station; and
repeatedly transmitting an NPRACH preamble based on the received NPRACH configuration information,
wherein, when a time gap between a time of completing a 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 by a difference between the guard time and the time gap in the last repeated transmission of the NPRACH preamble.
