Abstract: The present invention provides methods for controlling transmission of a sounding reference signal (SRS) in a wireless access system supporting machine type communication (MTC) and devices for supporting same. A method for controlling transmission of an SRS by an MTC terminal in a wireless access system supporting MTC, according to an embodiment of the present invention, can comprise the steps of: receiving an upper layer signal comprising information about an SRS which is to be repeatedly transmitted; configuring the SRS on the basis of the information about the SRS; and transmitting the SRS by means of a subband to which a physical uplink shared channel (PUSCH) is allocated and which is being frequency hopped. The subband comprises six physical resource blocks (PRB), and the SRS can be sequentially transmitted to the subband being frequency hopped.

Abstract: Provided are a method for performing a random access process in an unlicensed band, and a device using the same. The device receives a random access preamble (RAP) order instructing the transmission of a RAP. The device performs a clear channel assessment (CCA) in an unlicensed cell during an RAP window so as to transmit the RAP when the device succeeds in CCA.

Abstract: A method of monitoring a control signal in a wireless communication system, where the method is performed by a user equipment (UE) and includes: selecting at least one control resource set (CORESET) among a plurality of CORESETs based on an overlap between physical downlink control channel (PDCCH) monitoring occasions in the plurality of CORESETs; and monitoring a PDCCH only in the selected at least one CORESET, among the plurality of CORESETs. The method also includes: based on the at least one CORESET including a first CORESET, and based on a first reference signal of the first CORESET and a second reference signal of a second CORESET being associated with a same synchronization signal/physical broadcast channel block (SSB): monitoring the PDCCH in both the first CORESET and the second CORESET.

Abstract: The disclosure of the present invention proposes a wireless communication method. The method may comprise: performing a downlink (DL) reception on a DL resource; and performing an uplink (UL) transmission on a UL resource. The UL resource and the DL resource may use different numerologies each other. The numerologies may be defined by a subcarrier spacing and a cyclic prefix (CP) length.

Abstract: The present disclosure provides an operation method, associated with uplink (UL) transmission, of a terminal in a wireless communication system supporting dynamic resource sharing between an eMBB and a URLLC. More specifically, the method carried out by a terminal comprises receiving, from a base station, a UL grant for scheduling a UL transmission; receiving, from the base station, a control message including first information indicating the stopping of the UL transmission, and second information on a resource for which the UL transmission is to be stopped; and on the basis of the control message, determining whether a demodulation reference signal (DMRS) for the UL transmission is included in the resource for which the UL transmission is to be stopped.
