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
Claims20
An apparatus of a user equipment (UE) operable to perform device to device (D2D) discovery in a wireless network, the apparatus comprising:
- one or more processors configured to:
- decode, at the UE, D2D discovery parameters received from an eNodeB, wherein the D2D discovery parameters are associated with:
- a Nf parameter for D2D discovery that corresponds to defined resource blocks in a D2D discovery resource allocation, and a Nt parameter for D2D discovery that corresponds to defined subframes of the D2D discovery resource allocation;
- determine, at the UE, a UE D2D discovery resource from the D2D discovery resource allocation based, in part, on the D2D discovery parameters;
- and
- encode, at the UE, a D2D discovery message for transmission from the UE using the UE D2D discovery resource in the D2D discovery resource allocation;
- and
- memory configured to store the D2D discovery parameters received from the eNodeB.

At least one non-transitory machine readable storage medium having instructions embodied thereon for performing device to device (D2D) at a user equipment (UE) in a wireless network, the instructions when executed by one or more processors cause the UE to perform the following:
- decoding, at the UE, D2D discovery parameters received from an eNodeB, wherein the D2D discovery parameters are associated with:
- a Nf parameter for D2D discovery that corresponds to defined resource blocks in a D2D discovery resource allocation, and a Nt parameter for D2D discovery that corresponds to defined subframes of the D2D discovery resource allocation;
- selecting, at the UE, a UE D2D discovery resource from the D2D discovery resource allocation based, in part, on the D2D discovery parameters;
- and
- encoding, at the UE, a D2D discovery message for transmission from the UE using the selected UE D2D discovery resource in the D2D discovery resource allocation.
