Abstract: Proposed is a method for a first device for communicating wirelessly. The method can comprise a step of, from a second device, transmitting sidelink control information (SCI) comprising information relating to a demodulation reference signal (DMRS) pattern by means of a physical sidelink control channel (PSCCH) to the second device, mapping the DMRS on resources relating to a physical sidelink shared channel (PSSCH) on the basis of the information relating to the DMRS pattern and the length of a symbol duration of the PSSCH relating to the PSCCH, and transmitting the DMRS to the second device by means of the PSSCH.

Abstract: Proposed is a method for a first device to perform wireless communication. The method may include a step for generating a sidelink synchronization signal block (S-SSB) including a sidelink primary synchronization signal (SPSS), a sidelink secondary synchronization signal (SSSS), and a sidelink physical broadcast channel (PSBCH), and transmitting the S-SSB to a second device. For example, at least one of an SPSS-related symbol period, an SSSS-related symbol period, or a PSBCH-related symbol period may include a transition period. For example, the transition period may be determined on the basis of at least one of the priority of the SPSS, the priority of the SSSS, or the priority of the PSBCH.
