DEVICE FOR TRANSMITTING DEVICE-TO-DEVICE SYNCHRONIZATION SIGNAL IN LTE DEVICE-TO-DEVICE COMMUNICATION

摘要

The present invention relates to technology for transmitting a synchronization signal used in device-to-device communication. The present invention relates to a device for transmitting a device-to-device synchronization signal in LTE device-to-device communication, capable of detecting interference of a different terminal by periodically or aperiodically transmitting the synchronization signal, wherein the device for transmitting a device-to-device synchronization signal in LTE device-to-device communication comprises a terminal for determining a transmitting policy for a device-to-device synchronization signal by using one of periodic transmission, aperiodic transmission, continuous transmission, and transmission discontinuation of the device-to-device synchronization signal, when carrying out direct device-to-device communication with the different terminal.
