Method and device for detecting and generating synchronization signal for device-to-device wireless communication

摘要

Provided is a method of generating a Device-to-Device Synchronization Signal (D2DSS) by a terminal according to an embodiment of the present disclosure. The method includes determining a service attribute for identifying whether the terminal is serviced by at least one base station; and generating a D2DSS for identifying whether the terminal is serviced by the base station, based on the determination result. In addition, provided is a method of configuring D2D synchronization by a terminal according to an embodiment of the present disclosure. The method includes receiving a signal from at least one base station or another device; determining whether a synchronization signal is detected from the received signal; and when the synchronization signal is detected, configuring synchronization with the another device based on the timing reference of the detected synchronization signal.

1. A method for generating a device to device synchronization signal (D2DSS) by a terminal, the method comprising:
determining whether the terminal is in coverage of a base station; generating a D2DSS based on a first root index, if the terminal is in the coverage of the base station; and generating a D2DSS based on a second root index different from the first root index, if the terminal is out of coverage of the base station.
