摘要： Techniques and systems that improve throughput between a pair of nodes by using two multi-hop paths of one-way flows regardless of the one-way flows interfering with each other are described herein. These techniques enable nearly full-rate data flow through frame transmissions, even though these frame transmissions can interfere with substantially concurrent relay transmissions. In some implementations, relays on the two paths forward mixed frame signals to the next hop without trying to decode the mixed frame signals of interfered frames. The destination successfully recovers the useful information from the mixed frame signals by canceling out interference based on previously received frames.

摘要： An uncontrolled spatial multiple access system and method facilitating spatial multiple access for multiple devices in a wireless local-area network (WLAN). Embodiments of the system and method increase throughput of the wireless network by facilitating concurrent encoded frame transmission. Decoding of the quasi-overlapped frames is achieved using a chain decoding technique that takes data streams (or signals) containing the quasi-overlapping encoded frames and isolates each encoded frame so that the frame can be decoded. Quasi-overlapped frames means that the frames are overlapped in the body of the frame but not at the preamble (or headers) of the frames. Embodiments of the chain decoding also use interference nullifying and interference cancelation to enable concurrent quasi-overlapping transmission. A carrier counting multiple access technique of embodiments of the system and method allow wireless networks to retain their asynchronous nature while supporting spatial multiple access and maintain backwards compatibility with the IEEE 802.11 standard.

摘要： Described is a technology by which a gesture made with a source device (e.g., a cellular telephone), such as a throwing or pointing motion, is used to automatically set up a connection with another device to which the gesture is directed. Audio signals output during the gesture, e.g., such as at the start and end of the gesture, are detected by candidate (listening) devices. The device having the least time difference between detection of the start and end signals is the device that is generally best aligned with the throwing or pointing motion, and thus may be selected as the target device. Once selected, a connection such as a network connection may be set up between the source device and the target device for further communication, such as for application data exchange.

摘要： Systems and methods are described for mobile device collaboration. An exemplary collaborative architecture enables aggregation of resources across two or more mobile devices, in such a manner that the aggregation of resources is practical even considering the miniaturized and limited battery power of most mobile devices. In a video implementation, the exemplary collaborative architecture senses when another mobile device is in close enough proximity to aggregate resources. The collaborative architecture applies an adaptive video decoder so that each mobile device can participate in playing back a larger and higher-resolution video across combined display screens than any single mobile device could playback alone. A cross-display motion prediction technique saves battery power by balancing the amount of collaborative communication between devices against the local processing that each device performs to display visual motion across the boundary separating displays.

摘要： Implementations for retransmitting erroneous portions within a transmission frame are described. A sender transmits a transmission frame and the receiver performs error detection on portions of the transmission frame in order to determine if any are received in error. The receiver sets up a feedback channel and transmits acknowledgements to the receiver to indicate that one or more portions have been received and to identify any portions that are received with errors. At least some of the acknowledgements are transmitted prior to receipt of the entire transmission frame. The sender retransmits any portions that are identified as being erroneous within the transmission frame.

摘要： A fine-grained channel access system and method to facilitate fine-grained channel access in a high-data rate wide-band wireless local-area network (WLAN). Embodiments of the system and method divide an entire wireless channel into proper size subchannels commensurate with the physical layer data rate and typical frame size. Once the subchannels are defined, each node on the WLAN contends independently for each of the fine-grained subchannels. A first orthogonal frequency-division multiplexing (OFDM) technique is used to signal an access point on the WLAN that the node desires one or more of the subchannels. A second OFDM technique (which is different from the first OFDM technique) is used for data transmission. Sometimes there is contention between nodes that want the same subchannel. The access point resolves any contention between the nodes using a frequency domain contention technique that includes a frequency domain backoff technique.

摘要： A real-time task may initially be performed by a first thread that is executing on a first core of a multi-core processor. A second thread may be initiated to take over the performance of the real-time task on a second core of the multi-core processor while the first thread is performing the real-time task. The performance of the real-time tasks is then transferred from the first thread to the second thread with the execution of the second thread on the second core to perform the real-time task.

摘要： Embodiments include processes, systems, and devices that allow a white space base station to request available frequency ranges for white space transmission in a local area. A white space finder service models a primary user device's transmission signal propagation area using terrain data associated with the local area of the primary user device. The white space finder service also determines, based on the location of the white space base station and the modeled propagation area, one or more locally available, non-interfering frequency ranges and provides them to the white space base station. The white space base station compares the provided frequency ranges to policies and selects one or more of the available frequencies that accommodate the policies. The white space base station also maps the transmission frequency ranges to virtual frequency ranges for transmission by a software-defined radio employing spectrum virtualization.
