US 10,772,073 B2 · Synchronization method and device for device-to-device communication in wireless communication system

Abstract

The present invention relates to a communication technology and system converging the 5G communication system for supporting a data rate higher than that of the 4G system with IoT technology. The present invention is applicable to intelligent services based on 5G communication and IoT technologies (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security, and safety services. In detail, the discovery signal transmission method of a terminal in a wireless communication system supporting Device to Device (D2D) communication includes receiving discovery resource pool information from a base station, selecting a resource for transmitting discovery signal based on the discovery resource pool information, determining whether the selected resource is overlapped with a resource configured for transmitting a D2D synchronization signal, and determining whether to transmit the discovery signal based on the determination result.

Dependent claims

A discovery signal transmission method of a terminal in a wireless communication system supporting Device to Device (D2D) communication, the method comprising:

receiving information regarding a D2D discovery resource pool from a base station, selecting a resource from the D2D discovery resource pool for transmitting a discovery signal by the terminal, determining whether the selected resource is overlapped in time with a resource configured for transmitting a D2D synchronization signal by the terminal, and when a D2D synchronization signal transmission is configured to the terminal and the selected resource is overlapped with the resource configured for transmitting the D2D synchronization signal transmission, skipping transmission of the D2D discovery signal and transmitting the D2D synchronization signal in the selected resource.

A terminal for transmitting a discovery signal in a wireless communication system supporting Device to Device (D2D) communication, the terminal comprising:

a transceiver to transmit and receive signals to and from a base station or another terminal;
and a controller configured to control to:
receive, from the base station via the transceiver, information regarding a D2D discovery resource pool;
select a resource from the D2D discovery resource pool for transmitting the discovery signal from the terminal;
determine whether the selected resource is overlapped in time with a resource configured for transmitting a D2D synchronization signal from the terminal;
and when a D2D synchronization signal transmission is configured to the terminal and the selected resource is overlapped with the resource configured for transmitting the D2D synchronization signal transmission, skipping transmission of the D2D discovery signal and transmitting the D2D synchronization signal in the selected resource.
