    Abstract: When the frequency resource allocation is conveyed on a bandwidth that is different from a bandwidth on which the frequency resource allocation is sent, a receiving D2D UE needs to understand the resource allocations. A resource allocation method for device-to-device resource allocation is provided according to an example. The resource allocation method includes a first D2D user equipment (UE) receiving a downlink control information (DCI) from an access point, wherein the DCI comprises a first D2D frequency allocation and the first D2D frequency allocation comprises a first resource allocation field for transmission of data; setting a second resource allocation field of a second D2D frequency allocation of a sidelink control information (SCI) format according to the first resource allocation field; transmitting the SCI format to one or more additional D2D UEs; and transmitting the data on the resource according to the second D2D resource allocation.

    Abstract: A method for initiating a random access includes generating a first downlink control information (DCI) including random access parameters and selecting a control channel from a first downlink control channel in common search space of a first subframe and a second downlink control channel in a data region of the first subframe. The method also includes mapping the first DCI to the control channel and transmitting, by a communications controller to a UE, symbols of the first subframe including the first DCI in the control channel. Additionally, the method includes receiving, by the communications controller from the UE, a random access waveform in accordance with the random access parameters and transmitting, by the communications controller to the UE, after receiving the random access waveform, a second subframe including a second DCI in a control channel of the second subframe, where the second DCI includes scheduling information for a random access response.

    Abstract: In one embodiment, a method for delay scheduling includes determining whether a communications controller has information for a machine type communication (MTC) device and determining a first subframe to transmit a downlink control information (DCI) message on when the communications controller has information for the MTC device. The method also includes transmitting, by the communications controller to the MTC device, the first subframe including the DCI message and the information in accordance with the first subframe.

    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.
