摘要： Methods for wireless communications over a wideband carrier are provided. Time-frequency resources of the wideband carrier within a transmission time interval are divided into multiple time-frequency resource blocks. Each of the time-frequency resource blocks corresponds to a group of contiguous subcarriers of the wideband carrier and orthogonal frequency division multiplexing symbols. Data streams may be scheduled to be transmitted in different time-frequency resource blocks, and may be destined for different user equipments or the same user equipment. Baseband processing operations may be performed on data streams scheduled in different time-frequency resource blocks independently from one another. Separate control channels or one common control channel may be configured for data transmissions in different time-frequency resource blocks.

摘要： 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.

摘要： 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.
