Abstract

Technology for a user equipment (UE) operable to perform device to device (D2D) discovery in a wireless network is described. The UE can decode D2D discovery parameters received from an eNodeB. The UE can determine a UE D2D discovery resource from the D2D discovery resource allocation based, in part, on the D2D discovery parameters. The UE can encode a D2D discovery message for transmission from the UE to a second UE using the UE D2D discovery resource in the D2D discovery resource allocation.
