    摘要: Proposed is an operating method for a first device (100) in a wireless communication system. The method may comprise the steps of: transmitting a physical sidelink control channel (PSCCH) to a second device (200); transmitting, to the second device (200), a physical sidelink shared channel (PSSCH) on the basis of the PSCCH; determining a physical sidelink feedback channel (PSFCH) resource related to the PSSCH on the basis of an index of a slot related to the PSSCH and an index of a subchannel; and declaring sidelink (SL) radio link failure (RLF) for a connection between the first device (100) and the second device (200), on the basis that a discontinuous transmission (DTX) counter reaches a maximum DTX-related threshold.

    摘要: 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.

    摘要: 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.

    摘要: A method by which a first device performs wireless communication, and a device for supporting same are provided. The method can comprise the steps of: acquiring synchronization related to sidelink (SL) communication from a synchronization reference; receiving information related to a first power control parameter; generating a sidelink synchronization signal block (S-SSB) including a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS), and a physical sidelink broadcast channel (PSBCH); determining a first transmission power value on the basis of a downlink (DL) path loss between a base station and the first device and the information related to the first power control parameter; and transmitting the S-SSB to a second device on the basis of the first transmission power value and the synchronization related to the SL communication.
