Method for transmitting D2D signal and terminal therefor
A method is provided for transmitting a synchronization signal by a Device-to-Device (D2D) user equipment (UE). The UE receives discovery transmission pool configuration information and synchronization signal resource information, and transmits the synchronization signal based on the discovery transmission pool configuration information and the synchronization signal resource information. When a first subframe of a discovery transmission pool indicated by the discovery transmission pool configuration information 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. Otherwise, when the first subframe does not correspond to the indicated subframe, 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. The discovery transmission pool is periodically configured.
