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: 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 includes transmitting, by a communications controller to a user equipment (UE), a first data block on a first carrier and transmitting, by the communications controller to the UE, a first downlink control information (DCI) to initiate a hybrid automatic repeat request (HARQ) process associated with the first data block. The method also includes retransmitting, by the communications controller to the UE, the first data block and transmitting, by the communications controller to the UE, a second DCI, where the second DCI includes a first transmission indicator and an indicator of the first carrier, and where the second DCI continues the HARQ process.

Abstract: A method for providing user equipment access to millimeter wave stations through a microwave station includes receiving an indication of millimeter wave stations operating within a microwave coverage area of a microwave station. In a microwave band, information associated with the millimeter wave stations is broadcasted to user equipment in the microwave coverage area. A request is sent to the millimeter wave stations to transmit configuration signals over a microwave band. An instruction is transmitted over the microwave band to the user equipment to perform proximity measurements of the configuration signals. According to the proximity measurements, a request is sent to a particular millimeter wave station to transmit beamforming signals over a millimeter wave band. An instruction is transmitted over the microwave band to the user equipment to perform beamforming measurements of the beamforming signals. According to the beamforming measurements, the user equipment is switched to millimeter wave operation.
