Abstract: Proposed is a method for transmitting a physical random access channel (PRACH) preamble in a wireless communication system. Specifically, a method performed by user equipment (UE) comprises the steps of: receiving, from a base station, setting information including a first power ramping step for a two-step random access channel (RACH) and a second power ramping step for a four-step RACH; transmitting, to the base station, information including a first preamble and a physical uplink shared channel (PUSCH) for a two-step RACH on the basis of the first power ramping step; and transmitting, to the base station, a second preamble for a four-step RACH by using the second power ramping step, on the basis of the number of retransmissions of the information exceeding a maximum number of retransmissions associated with a preset two-step RACH.

Abstract: The present disclosure provides a method for receiving system information in a wireless communication system supporting a TDD narrowband. More specifically, a method performed by a terminal includes receiving first system information from a base station through an anchor carrier, the first system information including operation mode information on an operation mode of the system; determining a location of a non-anchor carrier for receiving second system information based on the operation mode information; and receiving the second system information from the base station through the non-anchor carrier, in which the operation mode information is configured in a guard band or an in-band. In this way, SIB1-NB is also transmitted and received on the non-anchor carrier.
