  • Publication number: 20190158926
    Abstract: A device may receive a request associated with adjusting the media output level of a sink device that is configured to output media content. The device may identify a source gain of a source device that is configured to provide the media content to the sink device, and a sink gain of the sink device. The device may identify a sink adjustment value for changing the sink gain based on the request for adjusting the media output level of the sink device, the source gain, and the sink gain. The device may transmit, to the sink device, a control signal to permit the sink gain to be changed based on the sink adjustment value. The media output level of the sink device is based on the source gain and the sink gain.

  • Patent number: 8887222
    Abstract: This disclosure relates to techniques to establish a multicast communication session between a source device and multiple sink devices in a Wireless Display (WD) system. Two or more sink devices may be interested in receiving the same media data from the source device. According to the techniques, the source device establishes a multicast session with the sink devices in the WD system, and sends a single copy of multicast media data for the multicast session to the interested sink devices using a receiving multicast port. The source device selects a receiving multicast port number as a destination identifier for each multicast session. The sink devices interested in receiving the media data of a given multicast session bind on the receiving multicast port for the multicast session. This disclosure describes several exemplary multicast subscription procedures to ensure correct binding on the receiving multicast port at each of the sink devices.

  • Patent number: 8842676
    Abstract: Certain embodiments of the present disclosure proposes a flexible method for scheduling of an uplink transmission simultaneously considering all active connections of a mobile station. A decision on scheduling priority can be made based on a metric that comprises QoS parameters and current traffic measurements. The weight factors may be applied for every QoS parameter per schedule type providing flexibility of the scheduling algorithm. The proposed scheduling algorithm may be applied to satisfy different QoS requirements for each service provider and application by changing weight factors if required.

  • Patent number: 8725143
    Abstract: This application provides techniques for robust handover to a target base station, based on performing initial ranging with the target base station. The techniques might generally include scanning neighboring base stations (BSs), selecting a target BS for a handover at least based on results of the scanning, performing initial ranging with the target BS, and sending a Handover Request to the target BS.

  • Patent number: 8611265
    Abstract: Embodiments of the present disclosure provide techniques for processing a HARQ data burst and/or a HARQ ACK message in the event a HARQ ACK message falls within a scanning or an unavailable interval of an MS. For certain embodiments, a HARQ ACK message may be postponed if it falls within the scanning or the unavailable interval of the mobile station. For certain embodiments, the HARQ data burst transmission may be postponed if the corresponding HARQ ACK message falls within a scanning or an unavailable interval of the mobile station. For certain embodiments, the HARQ ACK may be transmitted or received even if it falls within the scanning or the unavailable interval of the mobile station. However, the HARQ ACK message may not be processed during the scanning/unavailable interval.

  • Patent number: 8542650
    Abstract: Techniques, systems and methods for concurrent data and signaling for WiMAX handover are disclosed herein. The serving base station may receive a handover request message from a mobile station and transmit a parameter to the mobile station to indicate a time to suspend a first set of one or more service flows between the serving base station and the mobile station during a handover procedure and continue data exchange between the mobile station and the serving base station for a second set of one or more service flows during the handover procedure. The proposed techniques reduce the service suspension time during the handover procedure.

  • Patent number: 8526390
    Abstract: Methods and apparatus for allocating, modifying, and terminating a fixed data region (termed “sticky region allocation”) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame are provided. With sticky region allocation, the sticky region may be negotiated during the establishment of a connection between a base station and a user terminal, and a single MAP information element (MAP IE) may inform the user terminal of the location of the sticky region. Then, a user terminal can receive/send data bursts for a certain connection in multiple OFDM/OFDMA frames without needing a MAP IE for locating each burst in subsequent frames. Accordingly, the size of the control overhead, such as the downlink (DL) and uplink (UL) MAP messages, may be reduced. The reduced control overhead may increase the frame resources available for data traffic and thus, may boost the overall efficiency and performance of OFDM/OFDMA wireless systems.

  • Patent number: 8483041
    Abstract: Methods and apparatus for allocating a data region (termed “sticky region allocation”) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame so that a user terminal can receive/send data bursts for multiple OFDM/OFDMA frames, rather than inserting a MAP information element (MAP IE) for each user terminal in every frame, are provided. In this manner, the size of the control overhead, such as the downlink (DL) and uplink (UL) MAP messages, may be reduced. The reduced control overhead may increase the frame resources available for data traffic and thus, may boost the overall efficiency and performance of wireless systems using OFDM/OFDMA.

  • Patent number: 8385261
    Abstract: Methods and apparatus for setting the connection identifier (CID) mask length of a Hybrid Automatic Repeat-Request (HARQ)-MAP or a SUB-MAP pointer information element (IE) in a compressed downlink map (DL-MAP) of an orthogonal frequency-division multiple access (OFDMA) frame are provided in an effort to reduce the number of false indications in the CID mask, while also striving, as a secondary concern, to reduce the CID mask length. In this manner, an individual mobile station (MS) may not waste processing, battery power, or time interpreting a HARQ-MAP message or a sub downlink/uplink map (SUB-DL-UL-MAP) message that was not intended for this particular MS. For some embodiments where the CID mask length is set to be small, the control overhead (i.e., the size of the HARQ-MAP or the SUB-MAP pointer IE) may be decreased, and more of the OFDMA frame may be available for data traffic.

  • Patent number: 8284707
    Abstract: An embodiment of the invention is a technique for power saving in mobile communication. At least one of a base station (BS) and a mobile station (MS) is initialized for power saving using a downlink (DL) status and an uplink (UL) status associated with the BS and the MS, respectively, during communication between the BS and the MS. A first PSC mode is entered when both the DL and UL statuses indicate a silence period. A second PSC mode is entered when at least one of the DL and UL statuses indicates a talk period.
