Abstract
Embodiments of the claimed subject matter provide a method and apparatus for device discovery in device-to-device (D2D) communication. One embodiment of the method includes generating first information indicative of a first synchronization signal in response to a request from a first user equipment to be authenticated for D2D communication with one or more second user equipment. The first information corresponds to a sequence used to generate a primary synchronization signal for transmission by a serving cell for the first user equipment. This embodiment of the method also includes providing the first information to the first user equipment so that the first user equipment can transmit the first synchronization signal.
