摘要： 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.

摘要： The present disclosure 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 disclosure 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 invention provides a data transmitting method. In this method, a second device detects scheduling signaling transmitted by a first device, determines a Listen Before Talk (LBT) mechanism for channel contention configured by the first device, and a corresponding parameter; performs LBT, and transmits uplink data after the LBT is successfully performed. The LBT mechanism of the data transmission of the second device may be set through common control signaling for a group or all of second devices, and the second device determines the used LBT mechanism according to whether the common control signaling is received. The second device needs to report a capability of simultaneous transmission and reception on neighbor carriers to the first device, so that the first device properly schedules uplink transmission and downlink transmission of the second device according to the capability. According to the method provided by the present disclosure, the flexibility that the base station controls the LBT mechanism of the uplink transmission of the UE can be improved, the waste of uplink resources and downlink resources can be avoided, and coexistence with another device can be ensured.
