    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: In one embodiment, a method for transmitting a reference signal in a wireless communications system includes obtaining, by a base station, a radio frame and determining, by the base station, a first subset of subframes of the radio frame, where the first subset includes a first subframe of the radio frame, and where the first subframe includes a mandatory downlink signal. Also, the method includes transmitting the reference signal only in the determined first subset.

    Abstract: A method for operating a communications controller includes allocating a number of resource blocks to an enhanced physical downlink shared channel (ePDSCH), and identifying a starting point for the resource blocks of the ePDSCH, the starting point located within a control region of a subframe. The method also includes signaling to a user equipment (UE) the starting point of the resource blocks and the number of resource blocks allocated to the ePDSCH.

    Abstract: A method includes allocating, by a communications controller, a first set of resource blocks to an enhanced physical downlink shared channel (ePDSCH), where the ePDSCH has a first starting point and allocating, by the communications controller, a second set of resource blocks to an enhanced physical downlink control channel (ePDCCH). The method also includes identifying, by the communications controller, a second starting point for the ePDSCH, where the second starting point for the ePDSCH is located within a legacy control region, where the first starting point of the ePDCCH is located within the legacy control region, and where the second starting point of the ePDSCH is different than the first starting point of the ePDCCH. Additionally, the method includes signaling, by the communications controller to a user equipment (UE) the second starting point and a number of the second set of resource blocks allocated to the ePDSCH.

    Abstract: A method for device-to-device (D2D) communications includes generating, by a synchronization source, a primary device-to-device synchronization signal that is different from a primary synchronization signal (PSS) sent by an Evolved NodeB (eNodeB) and an existing uplink (UL) signal sent by device-to-device communications devices, and transmitting, by the synchronization source, the primary device-to-device synchronization signal in a single carrier frequency division multiple access (SC-FDMA) waveform.
