Abstract: The present disclosure provides a method for transmitting a synchronization signal (SS), the method comprising: performing a listen-before-talk (LBT) operation in a pre-defined window; if the LBT operation succeeds, transmitting an SS block (SSB) in the window, wherein the SSB comprises the SS, or the SSB comprises the SS and a physical broadcast channel (PBCH). Compared with the prior art, the present disclosure may significantly improve the efficiency of data transmission and the access performance for the communication system by relaxing the time when the base station implements the LBT, that is, allowing the base station to implement the LBT in the pre-defined window and transmit the SSB after the LBT succeeds.

Abstract: Provided are 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), with a transmission and receipt processing method and device for time-frequency synchronization between V2X terminals. When a synchronization signal to be transmitted is identical to a synchronization signal of an existing D2D terminal, time-frequency resources configured for the D2D terminal in a cell are reused to transmit the synchronization signal. When synchronization signal to be transmitted is different from a synchronization signal of an existing D2D terminal, reconfigured time-frequency resources are used to transmit the synchronization signal. The synchronization signal transmitted by a V2X terminal indicates a corresponding synchronization source type by using a value of an SLSS sequence index and/or a value of a PSBCH specified field.
