Abstract
Disclosed is a method for transmitting a synchronization signal. The method for transmitting a synchronization signal according to the present application may comprise the step of transmitting a synchronization signal according to a first action or a second action previously configured on the basis of a command from a base station.
Claims10
A method for transmitting a synchronization signal for Device-to-Device (D2D) discovery by a terminal, comprising:
- receiving, from a base station, a signal indicating a first behavior or a second behavior for transmission of the synchronization signal of the terminal;
- and
- transmitting the synchronization signal based on the received signal,
- wherein, when the received signal indicates the first behavior and the first subframe of a discovery pool corresponds to a resource for the synchronization signal, the synchronization signal is transmitted in the first subframe,
- wherein, when the received signal indicates the first behavior and the first subframe does not correspond to the resource for the synchronization signal, the synchronization signal is transmitted on a resource for the synchronization signal nearest and prior to the first subframe,
- wherein, when the received signal indicates the second behavior, the synchronization signal is transmitted at a predetermined period within the discovery pool.

A terminal for transmitting a synchronization signal for Device-to-Device (D2D) communication, comprising:
- a transceiver configured to transmit and receive a radio signal;
- and
- a processor configured to control the transceiver,
- wherein the processor is configured to:
- receive, from a base station, a signal indicating a first behavior or a second behavior for transmission of the synchronization signal of the terminal;
- and
- transmit the synchronization signal based on the received signal,
- wherein, when the received signal indicates the first behavior and the first subframe of a discovery pool corresponds to a resource for the synchronization signal, the synchronization signal is transmitted in the first subframe,
- wherein, when the received signal indicates the first behavior and the first subframe does not correspond to the resource for the synchronization signal, the synchronization signal is transmitted on a resource for the synchronization signal nearest and prior to the first subframe,
- wherein, when the received signal indicates the second behavior, the synchronization signal is transmitted at a predetermined period within the discovery pool.
