    摘要: Described are methods and devices for enabling D2D communications with signal structures that require minimal changes to the current LTE architecture. In the embodiments described, the eNB grants resources to UEs for D2D communication and either initiates or permits a pair of UEs to establish a D2D link. Certain embodiments are designed to minimize changes to the current LTE control signaling structure by having the control signaling always come from the eNB as in a normal cellular link so that the transmitting UE transmits over a data channel (e.g., PUSCH/PDSCH) that the receiving UE is able to decode.

    摘要: Embodiments of a User Equipment (UE) and methods for packet based device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, UE may be enabled for proximity services and may be configured to receive signaling from an enhanced node B (eNB) indicating resources allocated for D2D discovery. The UE may configure a discovery packet in accordance with a predetermined configuration to have at least a discovery payload and a cyclic-redundancy check (CRC). The discovery payload may include discovery-related content. The UE may be configured to transmit the discovery packet on at least some of the indicated resources for receipt by a receiving UE. In some embodiments, a demodulation reference signal (DMRS) may be selected to indicate a payload size and/or MCS of the discovery packet's payload.
