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

Abstract: Technology for a user equipment (UE) operable to perform mission critical communications with an eNodeB is disclosed. The UE can transmit a physical random access channel (PRACH) signal to the eNodeB that indicates a mission critical communication to be performed between the UE and the eNodeB. The PRACH signal can be transmitted in accordance with a first transmission time interval (TTI). The UE can receive a random access response (RAR) message from the eNodeB that includes a timing advance (TA) and a resource allocation for the mission critical communication. The RAR message can be transmitted from the eNodeB using a second TTI. The UE can perform the mission critical communication with the eNodeB in an uplink using the TA and the resource allocation indicated in the RAR message. The mission critical communication can be performed using a physical uplink shared channel (PUSCH) and in accordance with the second TTI.

Abstract: Technology for performing device-to-device (D2D) discovery is disclosed. A user equipment (UE) can identify a D2D discovery resource that is M subframes in a time domain, wherein M is a positive integer greater than one. The UE can generate K demodulation reference signal (DMRS) sequences to be transmitted from the UE for each subframe in the D2D discovery resource, wherein K is a positive integer greater than two. The UE can apply a predetermined orthogonal cover code (OCC) to each DMRS sequence. The predetermined OCC can be selected based on a value of M and a value of K. The UE can transmit the K DMRS sequences for each of the M subframes of the D2D discovery resource.
