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: 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: A method and system for including a base station that configures a first user equipment (UE) that is in a radio resource control connected state with the base station. The UE is configured to be a synchronization source and transmit a first device-to-device synchronization signal (D2DSS) by using a synchronization resource that comprises a time resource, a frequency resource or a time and frequency resource. The base station instructs the first UE to transmit the first D2DSS using the synchronization resource. The base station signals the UE to configure the UE separately from the signal to transmit the D2DSS, and both of the signals are performed with radio resource control signaling from the base station to the UE.

Abstract: The disclosure relates to a base station configuring component carriers to user equipment (UE). The base station determines one or more component carriers to configure based on the UE carrier aggregation capability and sends a first configuration signaling to configure the UE with the component carriers in one or more component carrier sets. The base station configures each of the component carrier sets with a first common parameters and operations set and sends a second configuration signaling to configure the component carrier sets of the UE with the first common parameters and operations set. The base station then sends a third configuration signaling to configure each of the component carriers in the UE with a second parameters and operations set.

Abstract: Notifying served user equipments (UEs) of the presence or absence of cell-specific reference signal (CRS) symbols transmitted by neighboring base stations in the physical downlink shared channel (PDSCH) region of a subframe can be achieved through various of signaling techniques. The served UE may be notified by communicating a one or multi-bit indicator in a physical layer signaling channel of the serving cell, such as the physical downlink control channel (PDCCH) of the subframe. Alternatively, the served UE may be notified through higher layer signaling.

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: A method for device-to-device (D2D) communication includes sensing D2D resources from a pool of resources for a predetermined duration to produce measurements of the D2D resources and determining statistics in accordance with the measurements of the D2D resources. The method also includes determining a first subset of the D2D resources in accordance with the statistics and transmitting, by a first user equipment (UE) to a second UE, data over the first subset of the D2D resources.
