Abstract: This specification provides a method for transmitting an NPRACH preamble in a wireless communication system supporting TDD. More specifically, the method performed by the UE includes: receiving, from a base station, NPRACH configuration information including control information for a repetition number of NPRACH preambles including symbol groups through a higher layer signaling; and transmitting, to the base station, the NPRACH preamble repeatedly through frequency hopping of a symbol group based on the NPRACH configuration information, in which a frequency location of the symbol group is determined based on a first parameter related to a start subcarrier and a second parameter related to the frequency hopping.

Abstract: Disclosed is a method for transmitting and receiving signals to enable a terminal to perform a random access channel procedure (RACH procedure) in an unlicensed band. In particular, the method comprises: transmitting an uplink signal including a first physical random access channel (PRACH) and a first physical uplink shared channel (PUSCH) to a base station; and receiving, from the base station, a downlink signal related to contention resolution in response to the uplink signal, wherein a power ramping counter is used to set the transmission power of the uplink signal, and the value of the power ramping counter may be increased on the basis of a transmission spatial beam for the transmission of the uplink signal being configured in the same manner as a transmission spatial beam for the transmission of a PRACH prior to the uplink signal.

Abstract: Provided are a method and device for transmitting and receiving a signal in a wireless communication system according to an embodiment of the present invention, the method comprising: receiving DCI for scheduling a PUSCH; and transmitting the PUSCH on the basis of the DCI. An FDRA field in the DCI includes LSBs of K bits including information about an RB set. The K bits are converted into L bits on the basis of the number N of RB sets set in the current active BWP being different from the number M of RB sets set in a specific BWP.

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.
