Abstract: According to an embodiment of the present invention, a method for transmitting and receiving a signal in a wireless communications system includes the steps of: transmitting an uplink data in a first subframe to a base station; and receiving a reception confirmation response to the uplink data on a downlink time-frequency resource of a second subframe associated with the first subframe, wherein if the second subframe transmits a shortened DMRS (Demodulation Reference Signal), the downlink time-frequency resource is included in at least a part of REs (Resource Elements) adjacent to the RE (Resource Element) transmitting the shortened DMRS, and the RE transmitting the shortened DMRS is the cell specified one of the REs capable of being reserved for the DMRS.

Abstract: Disclosed are a method for transmitting a signal for device-to-device (D2D) communication of a user equipment in a wireless communication system and an apparatus for the same. Specifically, the method includes transmitting a D2D signal assigned at least one of a first synchronization information, a second synchronization information and a scheduling assignment information in a scheduling assignment resource unit. The first synchronization information and the second synchronization information are configured to be transmitted with different periodicities.
