    Abstract: A method includes determining a first subframe on which to transmit a first downlink control information (DCI) message and determining a second subframe on which to transmit a first information. The method also includes determining a delay between the first subframe and the second subframe and transmitting, by a communications controller to a user equipment (UE), the second subframe in accordance with the delay.

    Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.

    Abstract: An embodiment method for operating a base station includes instructing, by the base station, a mobile device to transmit, over grouped communications resources, a first instance of a data structure for D2D signaling. The data structure includes a first data field that indicates at least one of a D2D frame number, a D2D multiplexing configuration, a resource allocation for D2D signaling, an identifier of a D2D synchronization source, a type of a D2D synchronization source, or whether the mobile device is in coverage of a network. The data structure also includes a second data field indicating at least one of whether a D2D signaling operation is prohibited, or a type of prohibited D2D signaling operation.

    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.
