    摘要： System and method embodiments are provided for controlling and managing in-network device-to-device (D2D) communications. In an embodiment, a method for a UE performing device-to-device (D2D) communication includes generating a D2D buffer status report (BSR) for a D2D communication link between the UE and a second UE that provides information related to an amount of D2D data available for transmission, wherein the D2D BSR comprises a D2D BSR logical channel identifier (LCID); transmitting the D2D BSR in a control element; receiving, a resource allocation for the D2D link; and transmitting D2D data over the allocated resources.

    摘要： Systems and methods for User Equipment (UE) synchronization for Device-to-Device (D2D) out-of-coverage communication are provided. In an embodiment, a method in an in-coverage (IC) UE for the IC UE to become a synchronization source for out-of-coverage UEs for D2D communication includes obtaining, by the IC UE scanning parameters; scanning, by the IC UE, for out-of-coverage synchronization signals; transmitting, by the IC UE, a measurement report to a Transmission Point (TP) in response to a report trigger, the measurement report comprising information of one or more received out-of-coverage synchronization signals; receiving, by the IC UE, a configuration command from the TP instructing the IC UE to become a synchronization source in response to a configuration command from the TP; and transmitting, by the IC UE, a D2D synchronization signal (SS) for a duration of time or until instructed not to do so by the TP.

    摘要： A method for performing open discovery in a communications system includes determining, by a device-to-device (D2D) device, resource allocation information for a discovery cycle including discovery resources allocated for transmission of discovery signals by D2D devices. The method also includes selecting, by the D2D device, a first discovery resource of the discovery cycle in accordance with the resource allocation information, and transmitting, by the D2D device, a discovery signal in the selected first discovery resource.

    摘要： Embodiments are provided for configuring channel measurements and reporting by a user equipment (UE). The embodiments avoid unnecessary cell measurements and resulting reporting transmissions by the UE in network scenarios with restricted downlink transmissions from serving cells. A method by a network component includes sending, to the UE, a data transmission pattern for transmissions on downlinks from multiple cells serving the UE. The data transmission pattern indicates a plurality of subframes including one or more restricted subframes where transmissions from one of the cells are restricted. The method further includes sending, to the UE, a measurement pattern allocating measurements and reports for a cell from the UE to the cells at corresponding designated subframes of the subframes in the data transmission pattern. The UE transmits measurement reports to an assisting serving cell during the one or more restricted subframes.
