    Abstract: A method of transmitting data of a V2X communication device is disclosed. The method of transmitting data of the V2X communication device includes measuring a plurality of specific values related to a channel state of a specific channel via a plurality of antenna ports, and each of the plurality of specific values may be measured via each of the plurality of antenna ports. Further, the V2X communication device may determine whether the specific channel is in an idle state based on the plurality of specific values, and, if the specific channel is in the idle state, simultaneously transmit service data to a plurality of adjacent devices via the specific channel using the plurality of antenna ports.

    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.
