Abstract
Disclosed is a method for transmitting a D2D synchronization signal. The method for transmitting a D2D synchronization signal according to the present application may comprise transmitting a synchronization signal from a synchronization signal resource closest to the first subframe from among the subframes previous to the first subframe if the first subframe of a discovery transmission pool does not correspond to the synchronization signal resource.
Claims10
A method for transmitting a synchronization signal in a Device-to-Device (D2D) terminal, comprising:
- receiving a discovery transmission pool configuration and synchronization signal resource information;
- and
- transmitting the synchronization signal based on the discovery transmission pool configuration and the synchronization signal resource information,
- wherein, when a first subframe of a discovery transmission pool indicated by the discovery transmission pool configuration corresponds to a subframe indicated by the synchronization signal resource information, the synchronization signal is transmitted in the first subframe of the discovery transmission pool,
- wherein, when the first subframe of the discovery transmission pool indicated by the discovery transmission pool configuration does not correspond to the subframe indicated by the synchronization signal resource information, the synchronization signal is transmitted in a subframe positioned before the first subframe of the discovery transmission pool and nearest to the first subframe of the discovery transmission pool among subframes indicated by the synchronization signal resource information.
A terminal for transmitting a Device-to-Device (D2D) synchronization signal, 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 a discovery transmission pool configuration and synchronization signal resource information;
- and
- transmit the synchronization signal based on the discovery transmission pool configuration and the synchronization signal resource information,
- wherein, when a first subframe of a discovery transmission pool indicated by the discovery transmission pool configuration corresponds to a subframe indicated by the synchronization signal resource information, the synchronization signal is transmitted in the first subframe of the discovery transmission pool,
- wherein, when the first subframe of the discovery transmission pool indicated by the discovery transmission pool configuration does not correspond to the subframe indicated by the synchronization signal resource information, the synchronization signal is transmitted in a subframe positioned before the first subframe of the discovery transmission pool and nearest to the first subframe of the discovery transmission pool among subframes indicated by the synchronization signal resource information.
