    Abstract: 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.

    Abstract: 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.

    Abstract: Embodiments are provide for communicating data or other non-control information messages within a downlink control channel directly, rather than in a data channel or broadcast channel. Thereby, radio resource utilization can be substantially improved in the cellular system, such as in the case of transmitting smaller data packets. In an embodiment, a transmitter arranges a set of time-frequency radio resources, associated with a downlink control channel, for transmitting information other than control information sent on the downlink control channel. The transmitter then sends, on the set of time-frequency radio resources, a data information message comprising the information other than the control information. The information other than the control information comprises one of user-specific data information and broadcast data information. A receiver then receives on the downlink control channel, control information and the data information message.

    Abstract: Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

    Abstract: It is possible to reduce latency and/or overhead when performing a platoon handover by using the leading vehicle in the platoon to communicate handover requests and/or initial resource requests (e.g., random access transmissions) on behalf of trailing vehicles in the platoon. In one example, a leading vehicle in a platoon communicates a handover request to a source AP to request handover of the entire platoon from the source AP to a target AP. In such an example, the source AP then communicates handover commands to each vehicle in the platoon without receiving separate handover requests from the trailing vehicles, thereby reducing overhead in the access network. The handover commands notify the trailing vehicles of the handover, and may be sequentially communicated to the trailing vehicles based on their order in the platoon.
