Abstract: A method for performing wireless communication by a first apparatus is proposed. The method may comprise the steps of: determining power related to a sidelink (SL) transmission, on the basis of a downlink pathloss, wherein the SL transmission includes at least one from among a sidelink-synchronization signal/physical sidelink broadcast channel (S-SS/PSBCH) block transmission, a physical sidelink control channel (PSCCH) transmission, a physical sidelink shared channel (PSSCH) transmission, and a physical sidelink feedback channel (PSFCH) transmission; and performing the SL transmission on the basis of the power related to the SL transmission. For example, on the basis of being configured to monitor a downlink control information (DCI) format 0_0, the downlink pathloss may be determined on the basis of a first reference signal (RS) used for control of power related to a physical uplink shared channel (PUSCH) transmission to be scheduled by the DCI format 0_0. For example, on the basis of not being configured to monitor the DCI format 0_0, the downlink pathloss may be determined on the basis of a second RS related to a synchronization signal block (SSB) for acquiring a master information block (MIB).

Abstract: A method for performing radio communication by a first apparatus, and an apparatus for supporting same may be provided. The method may comprise the steps of: obtaining second bits by attaching cyclic redundancy check (CRC) bits to first bits associated with second sidelink control information (SCI); obtaining third bits on the basis of channel coding for the second bits; obtaining fourth bits by performing rate matching on the third bits on the basis of the number of modulation symbols, wherein the number of modulation symbols is obtained on the basis of the number of first bits, the number of CRC bits, a beta-offset value included in first SCI associated with the second SCI, an alpha value configured for each resource pool, the number of symbols associated with transmission of a physical sidelink shared channel (PSSCH), the number of resource elements (Res) associated with transmission of the second SCI for each symbol, and a gamma value, the gamma value being the number of vacant REs in a resource block (RB) to which a last symbol associated with the second SCI belongs; and transmitting the second SCI to a second apparatus via the PSSCH on the basis of scrambling, modulation, and mapping for the fourth bits.

Abstract: Proposed is a method for a first device to perform wireless communication. The method may include a step for transmitting sidelink control information (SCI) to a second device through a first physical sidelink control channel (PSCCH) or a first physical sidelink shared channel (PSSCH) related to the first PSCCH, and transmitting data to the second device through the first PSSCH related to the first PSCCH. For example, the SCI may include combination information related to the positions of a plurality of sidelink (SL) resources, and information related to the relative position of a resource on which the first PSSCH is transmitted among the plurality of SL resources.
