Abstract: This disclosure describes communication techniques that may be used within a multiple-processor computing platform. The techniques may, in some examples, provide software interfaces that may be used to support message passing within a multiple-processor computing platform that initiates tasks using command queues. The techniques may, in additional examples, provide software interfaces that may be used for shared memory inter-processor communication within a multiple-processor computing platform. In further examples, the techniques may provide a graphics processing unit (GPU) that includes hardware for supporting message passing and/or shared memory communication between the GPU and a host CPU.

Abstract: In general, techniques are described for coding picture order count values identifying long-term reference pictures. A video decoding device comprising a processor may perform the techniques. The processor may determine least significant bits (LSBs) of a picture order count (POC) value that identifies a long-term reference picture (LTRP). The LSBs do not uniquely identify the POC value with respect to the LSBs of any other POC value identifying any other picture in a decoded picture buffer (DPB). The processor may determine most significant bits (MSBs) of the POC value. The MSBs combined with the LSBs is sufficient to distinguish the POC value from any other POC value that identifies any other picture in the DPB. The processor may retrieve the LTRP from the decoded picture buffer based on the LSBs and MSBs of the POC value, and decode a current picture of the video data using the retrieved LTRP.

Abstract: A low standby power DC-DC converter can be powered down during standby mode. The DC-DC converter can be periodically awakened between sleep cycles to check if the output voltage needs to be recharged (refreshed). The duration of the sleep cycles can be varied to accommodate for changing load conditions that would affect the output voltage.

Abstract: Techniques for performing WLAN system scanning and selection are described. A terminal performs multiple iterations of scan to detect for WLAN systems. A scan list containing at least one WLAN system to detect for is initially determined. For each scan iteration, a scan type may be selected from among the supported scan types. The selected scan type may indicate passive scan or active scan, frequency channels to scan, etc. A scan may be performed based on the selected scan type. Signal strength measurements are obtained for access points received during the scan and used to identify detected access points. After all scan iterations are completed, candidates access points are identified based on the scan results, e.g., based on the signal strength measurements for the detected access points and a detection threshold. The best candidate access point may be selected for association by the terminal.

Abstract: A method includes generating a data packet at an access point. The data packet is to be communicated using a waveform that includes a first set of tones that is allocated to a first destination device and a second set of tones that is allocated to a second destination device. The first set of tones is non-overlapping with respect to the second set of tones, and each tone of the first set of tones and each tone of the second set of tones is an orthogonal frequency-division multiple access (OFDMA) tone. The method also includes transmitting the data packet to the first destination device via an institute of electrical and electronics engineers (IEEE) 802.11 wireless network and transmitting the data packet to the second destination device via the IEEE 802.11 wireless network.

Abstract: Dynamic control of transport protocols utilized in the streaming of media content based in part on the type of content, latency requirements, network conditions and/or device capabilities is described. The techniques provide a source device to dynamically switch between User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) to stream media content to a sink device. For example, during a Wi-Fi peer-to-peer remote display session associated with real-time media content (e.g., live streaming sporting event, or gaming applications), the source device may utilize Real-time Transport Protocol (RTP) over UDP to transmit the media stream to the sink device. Conversely, when the media content is not latency critical, such as playback of stored media (e.g., movie), the source device may dynamically switch to RTP over TCP in order to provide reliable data transmission.

Abstract: Apparatus and methods are directed to calibrating a delay within a wireless access point for determining a position of a mobile station. One method includes receiving an initial packet at an eavesdropping device, receiving a response packet, sent by another entity, at the eavesdropping device, computing a time difference based upon the packet arrival times, and providing the time difference to a position determination entity. Another method includes providing a request to appropriate eavesdropping devices to send information, receiving, from each appropriate eavesdropping device, a time difference which represents a difference in a time of arrival of a packet transmitted by the wireless access point and a time of arrival of a packet transmitted by the mobile station, determining a processing delay estimate based upon the time differences, and determining a position of the mobile station based upon the processing delay estimate and the received time differences.

Abstract: A method and apparatus for minimizing transmit signal interference is provided. The method includes the steps of: receiving a signal and amplifying the received signal. The received signal is then mixed with an intermediate frequency signal to obtain a baseband modulated signal. The baseband modulated signal is first filtered in an RC filter. The resulting signal is then divided by a preselected amount and the first divided portion is sent to a main path of a biquad filter, which produces a first stage biquad filtered signal. The second portion of the divided signal is sent to an auxiliary path of the biquad filter, and produces a second filtered signal. The first and second signals are then recombined and sent to the second stage of the biquad filter, where further filtering takes place.

Abstract: Beacon transmissions by access points (e.g., femtocells) are controlled in an attempt to increase the number of beacons seen by the access terminals in the vicinity of the access points. In some aspects, interference between beacons is reduced by, for example, scheduling beacon transmissions of neighboring access points at different times. In some aspects, beacon transmissions are scheduled in a manner (e.g., allocated in substantially contiguous timeslots and/or allocated to different frequencies) that enables access terminals to acquire all relevant beacons in a relatively short time frame.

The generated plurality of inter-layer reference pictures may be inserted into a reference picture list. A current picture in the enhancement layer may be coded using the reference picture list. The inter-layer filters may comprise default inter-layer filters or alternative inter-layer filters signaled in a sequence parameter set, video parameter set, or slice header.

Abstract: Methods, systems, and devices are described for wireless communication at an access point (AP). A scheduling procedure for using a full duplex wireless local area network (WLAN) AP with legacy station (STA) compatibility (e.g., half duplex) may be implemented. For example, a system may include a full duplex AP and have half duplex STAs with two antennas each. The scheduling procedure may involve dynamic grouping of STAs into half duplex sets, for example, based at least in part on location information of the STAs. The STAs may be grouped such that the AP is able to transmit to one of the half duplex sets while concurrently receiving from another of the half-duplex sets. The AP may employ beamforming, via the STAs, to reduce interference between full duplex in-band communications.
