    Abstract: Provided, according to one embodiment of the present disclosure, is a method for a first device transmitting a PSCCH and a PSSCH to a second device. The method may comprise the steps of: determining whether, in the entire frequency band of one PSSCH sub-channel, a first DMRS symbol is occupied by a resource region associated with a PSCCH; on the basis of whether the first DMRS symbol is occupied by the resource region associated with the PSCCH, determining a position, of a reference symbol in a PSSCH resource, in which a second SCI is mapped; mapping the second SCI on the basis of the position of the reference symbol in the PSSCH resource; and transmitting the second SCI to a second device via the PSSCH.

    Abstract: A method for performing wireless communication by a first device and a device for supporting same are provided. The method may comprise the steps of: receiving, from a second device, sidelink control information (SCI) including a field indicating transmission of a sidelink (SL) channel state information reference signal (CSI-RS); on the basis of the field indicating the transmission of the SL CSI-RS, determining that a report on SL channel state information has been requested by the second device; on the basis of the SL CSI-RS, acquiring the SL channel state information related to the channel state between the first device and the second device; and transmitting the SL channel state information to the second device.

    Abstract: Provided are a method for a first device carrying out wireless communication, and a device supporting same. The method may comprise the steps of: receiving, from a base station, information on the number of sidelink synchronization signal blocks (S-SSBs) transmitted in an S-SSB period; and, on the basis of the information on the number of S-SSBs, transmitting, in the S-SSB period, one or more S-SSB including a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS) and a physical sidelink broadcast channel (PSBCH). Here, the number of S-SSBs may be selected from among one or more element included in a set of the number of S-SSBs transmittable in the S-SSB period, wherein the set of the number of S-SSBs transmittable in the S-SSB period may be configured differently on the basis of sub-carrier spacing (SCS) and frequency range (FR).

    Abstract: Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: determining selectable candidate slots for sidelink (SL) transmission; determining N slots for sensing from a first slot among the selectable candidate slots, wherein the N slots are at least one slot for selecting at least one SL resource from among SL resources included in the selectable candidate slots; selecting the at least one SL resource based on the sensing for the N slots; and transmitting, to a second device through a physical sidelink shared channel (PSSCH), a medium access control protocol data unit (MAC PDU) based on the at least one SL resource, wherein a value of N is a positive integer.

    Abstract: 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: transmitting a random access preamble to a base station; receiving, from the base station, a random access response message related to the random access preamble; transmitting, to the base station, a radio resource control (RRC) setup request message on the basis of the random access response message; receiving, from the base station, an RRC setup message as a response to the RRC setup request message; and receiving, from the base station, an RRC message including a setup related to a Uu bandwidth part (BWP) and a setup related to a sidelink (SL) BWP, wherein first device cannot perform SL communication through the SL BWP on the basis of the fact that the numerology of the Uu BWP and the numerology of the SL BWP are different.
