User equipment and method for packet-based device-to-device (D2D) discovery in LTE networks

摘要

Embodiments of user equipment (UE) and methods for packet-based device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, the UE may be capable of supporting proximity services and is configured to receive signaling from an evolved Node B (eNB) indicating resources allocated for D2D discovery. obtain. The UE can configure a discovery packet according to a predetermined configuration to have at least a discovery payload and a cyclic redundancy checksum (CRC). The discovery payload may include discovery related content. The UE may be configured to send a discovery packet on at least some of the indicated resources for reception by the receiving UE. In some embodiments, a demodulation reference signal (DMRS) may be selected to indicate the payload size and / or MCS of the discovery packet payload.
