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.

Abstract: Disclosed is a method by which a terminal transmits a physical uplink shared channel (PUSCH) in a band equal to or higher than 52.6 GHz in a wireless communication system. Specifically, the method may comprise: receiving a system information block (SIB); receiving a random access response (RAR) uplink (UL) grant for scheduling the PUSCH; and transmitting the PUSCH on the basis of the RAR UL grant, wherein, on the basis that the SIB includes a parameter indicating that a channel access procedure (CAP) should be applied, the number of bits of a field for indicating a channel access type included in the RAR UL grant is 2, and on the basis that the SIB does not include the parameter, the number of bits of a field for indicating the channel access type included in the RAR UL grant is 0.
