Disclosed are a method and an apparatus for generating a reference signal in a device-to-device communications. A DM RS sequence is generated based on at least one among an identifier of a D2D signal transmission apparatus, an identifier of a D2D signal reception apparatus, an identifier having a pre-determined value, an identifier of a synchronization source, an identifier of a service group, an identifier of a task group, and an identifier of a resource set which is set for D2D communications. The DM RS sequence generation input variables including an identifier can be various variables including the identifiers above as well as an input variable constituting a cyclic shift value of a sequence, an index of a sequence, etc. A D2D terminal can obtain the input variables in different methods depending on communications environment. |
