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.

Abstract: The present discloser is related to a method, by a user equipment (UE), for transmitting uplink data through a preconfigured uplink resource (PUR) in a wireless communication system and a apparatus therefor. The UE receives, from a base station, PUR configuration information including a PUR transmission time, in an RRC connected state (radio resource control connected state), transitions from the RRC connected state to an RRC idle state, determines whether a timing advance (TA) related to uplink transmission timing is valid based on a reference signal received power (RSRP) change of a specific reference signal, wherein the RSRP change is a difference value between a first RSRP value measured based on point A and a second RSRP value measured based on point B, and transmits, to the base station, the uplink data at a first PUR transmission time based on the determination result and the PUR configuration information.
