Abstract: This specification provides a method for transmitting a random access preamble by a user equipment (UE) in a wireless communication system supporting a narrow band-Internet of things (NB-IoT). Specifically, the UE receives a downlink control channel (Physical Downlink Control Channel (PDCCH)) including downlink control information (DCI) from an eNB and the DCI includes an indicator indicating whether a preamble format of a random access preamble allocated to the UE is format 0/1 or format 2. Then, the UE transmits the random access preamble to the eNB in a subcarrier allocated to the UE according to the preamble format and receives a random access response from the eNB in response to the random access preamble.
