The present application relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present application may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present application discloses a method for transmitting a synchronization signal and a PSBCH in V2X communication, comprising the following steps of: determining, by a VUE, a value of NIDSL according to its reference synchronization source, NIDSL denoting a sidelink synchronization source ID; determining, by the VUE, an SLSS and/or a DMRS of a PSBCH different from a D2D system according to the value of NIDSL, wherein the SLSS comprises a PSSS and an SSSS, and the DMRS of the PSBCH is determined by a DMRS sequence of the PSBCH and an orthogonal mask of the DMRS of the PSBCH; and, transmitting, by the VUE, the SLSS and the PSBCH. The present application further discloses a device for transmitting a synchronization signal and a PSBCH in V2X communication. With the present application, a D2D terminal is prevented from measuring an S-RSRP at a DMRS position of a PSBCH transmitted by a VUE, or a D2D terminal is prevented from measuring an S-RSRP value meeting synchronization source reselection conditions at a DMRS position of a PSBCH transmitted by a VUE, so that the influence on the synchronization process of the D2D terminal from the VUE can be avoided easily and effectively.
