Abstract: Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: obtaining a sidelink (SL) discontinuous reception (DRX) configuration including information related to a timer for an active time and information related to a hybrid automatic repeat request (HARQ) round trip time (RTT) timer; starting the timer for the active time; receiving, from a second device through a physical sidelink control channel (PSCCH) based on a first SL resource, a first sidelink control information (SCI) for scheduling of a physical sidelink shared channel (PSSCH) and a second SCI; and receiving, from the second device through the PSSCH based on the first SL resource, the second SCI and data. Herein, based on resource allocation information for a second SL resource being included in the first SCI, the first device may not monitor retransmission of the data from the second device in a time domain between the first SL resource and the second SL resource, and based on the resource allocation information for the second SL resource not being included in the first SCI, the HARQ RTT timer included in the SL DRX configuration may be started by the first device.

Abstract: Disclosed herein is a method for receiving a demodulation reference signal (DMRS) in a wireless communication system. In particular, the method may include receiving a synchronization signal/physical broadcast channel (SS/PBCH) block, acquiring information about control resource set (CORESET) #0 from a PBCH included in the SS/PBCH block, receiving a physical downlink control channel (PDCCH) through CORESET #0, and receiving a physical downlink shared channel (PDSCH) scheduled based on the PDCCH and a DMRS for the PDSCH, wherein, based on the PDCCH being addressed to a system information-radio network temporary identifier (SI-RNTI), a reference point for the DMRS may be subcarrier #0 of a resource block (RB) having a lowest number among RBs included in CORESET #0.

Abstract: A method by which a first device performs wireless communication is presented. The method can comprise the steps of: determining a first selection window for selecting a resource related to sidelink transmission; determining N number of preset second selection windows in the first selection window; selecting a resource on the basis of the number of idle resources in the N number of second selection windows; and transmitting, on the resource, a PSCCH and a PSCCH related to the PSCCH to a second device. For example, N can be a positive integer.

Abstract: A method for performing wireless communication by a first device is proposed in an embodiment. The method may comprise the steps of: configuring one or more bandwidth parts (BWPs) associated with communication with a base station; receiving first control information from a first search space for the first control information on the one or more BWPs; and receiving second control information from a second search space for the second control information on the one or more BWPs. For example, on the basis of the base station allocating, to the first device, resources associated with sidelink transmission in a carrier in which Uu communication is performed, the first search space and the second search space can overlap.

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.
