Abstract
An embodiment of the present invention relates to a method for transmitting a synchronization signal in a wireless communication system, the method comprising the steps of: generating a synchronization signal on the basis of a cell ID which is determined depending on whether a terminal for transmitting the synchronization signal is a terminal located outside of a coverage; and transmitting the synchronization signal.
Claims7
A method of receiving a device-to-device (D2D) synchronization signal (SS) in a wireless communication system, the method comprising:
- receiving from a second D2D user equipment (UE), by a first D2D UE, a primary D2D SS including ID information, the ID information informing whether the second D2D UE is an in-coverage UE or an out-of-coverage UE;
- and
- receiving, by the first D2D UE, a secondary D2D SS based on the primary D2D SS,
- wherein the primary D2D SS is transmitted on a same subframe as the secondary D2D SS and a Physical Sidelink Broadcast Channel (PSBCH), and
- wherein a transient period is included in a transmission region of the secondary D2D SS.
A first device-to-device (D2D) user equipment (UE) for receiving a synchronization signal (SS) in a wireless communication system, the first D2D UE comprising:
- a transmitter;
- a receiver;
- and
- a processor,
- wherein the processor is configured to control the receiver to:
- receive, from a second D2D UE, a primary D2D SS including ID information, the ID information informing whether the second D2D UE is an in-coverage UE or an out-of-coverage UE, and
- receive a secondary D2D SS based on the primary D2D SS,
- wherein the primary D2D SS is transmitted on a same subframe as the secondary D2D SS and a Physical Sidelink Broadcast Channel (PSBCH), and
- wherein a transient period is included in a transmission region of the secondary D2D SS.
