Embodiment Construction

[0016] The following description and drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, procedural, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.

[0017] figure 1 A portion of an end-to-end network architecture of an LTE network with various network components is shown according to some embodiments. The network architecture includes a radio access network (RAN) (e.g., E-UTRAN or Evolved Universal Terrestrial Radio Access Network as depicted) 100 and a core network 120 (e.g., shown as Evolved Packet Core (EPC)). For convenience and conciseness, only a part of the core network 120 and the RAN 100 are shown.

[0018] Core network 120 includes Mobility Management Entity (MME) 122 , Se...

Abstract

This document generally describes user devices and methods for packet-based device-to-device discovery. In some embodiments, the UE may be ProSe enabled and may be configured to receive signaling from an enhanced Node B (eNB) indicating resources allocated for D2D discovery. The UE may configure the discovery packet to have at least a discovery payload and a cyclic redundancy check (CRC) according to a predetermined configuration. The discovery payload may include discovery-related content. The UE may be configured to send discovery packets on at least some of the indicated resources for reception by a receiving UE. In some embodiments, a demodulation reference signal (DMRS) may be selected to indicate the payload size and / or the MCS of the discovery packet's payload.
