  • Patent number: 10390230
    Abstract: A device includes circuitry that identifies one or more basic service sets (BSSs) that include at least one access point (AP) and one or more corresponding stations (STA) associated with an extended service set (ESS) based on one or more location or configuration parameters. The circuitry also determines ESS color information associated with the one or more BSSs of the ESS, and transmits a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to the one or more BSSs that includes an enhanced MPDU delimiter indicating at least one of the ESS color information, BSS color information, or spatial reuse parameters (SRPs).

  • Publication number: 20190253801
    Abstract: Embodiments are described for a method for localizing a set of speakers (106) and microphones (108), having only the times of arrival between each of the speakers and microphones. An autodiscovery process (107) uses an external input to set: a global translation (3 continuous parameters), a global rotation (3 continuous parameters), and discrete symmetries, i.e., an exchange of any axis pairs and/or reversal of any axis. Different time of arrival acquisition techniques may be used, such as ultrasonic sweeps or generic multitrack audio content. The autodiscovery algorithm is based in minimizing a certain cost function, and the process allows for latencies in the recordings, possibly linked to the latencies in the emission.

  • Patent number: 10342029
    Abstract: A method includes detecting, using a WiFi access point, channel use data indicating traffic on a plurality of channels of an unlicensed LTE band in a wireless network. The method further includes providing the channel use data to a Long Term Evolution (LTE) access point. The method further includes selecting, using the LTE access point, a channel for use in transmitting data by the LTE access point from among the plurality of channels based on the channel use data from the WiFi access point. The method further includes providing, from the LTE access point, an indication of an upcoming transmission configured to transmit data on the channel to the WiFi access point. The method further includes broadcasting one or more messages from the WiFi access point to one or more WiFi nodes, the one or more messages configured to prevent the WiFi nodes from transmitting on the channel.

  • Publication number: 20180367939
    Abstract: Systems and methods are described for an adaptive audio system that renders reflected sound for adaptive audio systems in different ways depending on the orientation of at least one speaker in a set of speakers. A speaker of the system may comprise an integrated speaker having front-firing and upward-firing drivers, a sensor to determine the orientation of the speaker (e.g., horizontal or vertical) and a transceiver and control unit that transmits the orientation to a decoder and receives updated speaker feeds from the renderer based on the orientation.

  • Publication number: 20180115733
    Abstract: A system and method of interfacing between a source media device, a destination media device and wireless speakers. A media stick provides the output video signal to the destination media device via a wired signal path, and provides the output audio signal to the wireless speakers via a wireless signal path. In this manner, a user may use a single device—the media stick—as both a connector between the devices and to provide the audio signal to the wireless speakers.

  • Patent number: 9875751
    Abstract: Embodiments are directed processing adaptive audio content by determining an audio type as one of channel-based audio and object-based audio for each audio segment of an adaptive audio bitstream, tagging the each audio segment with a metadata definition indicating the audio type of the corresponding audio segment, processing audio segments tagged as channel-based audio in a channel audio renderer component, and processing audio segments tagged as object-based audio in an object audio renderer component that is distinct from the channel audio renderer component. Object-based audio is rendered through an object audio renderer interface that dynamically adjusts processing block sizes of the object audio segments based on timing and alignment of metadata updates and maximum/minimum block size parameters.

  • Patent number: 9698945
    Abstract: In some aspects, the disclosure is directed to methods and systems for protocol coexistence. Within a frequency band of a wireless local area network (WLAN), a device implemented for operation in at least a non-WLAN protocol can determine that the frequency band is quiet at a first time instance. The device can transmit a message in WLAN protocol responsive to the determination and prior to operation in the non-WLAN protocol within the frequency band. The message can have a receiver address other than an address belonging to other devices operating within the frequency band.

    Abstract: Various methods and systems are provided for time domain coexistence of RF signals. In one example, among others, a method includes obtaining access to a WLAN channel during a free period of a coexisting cellular connection, providing a RDG to allow another device to transmit for a duration corresponding to at least a portion of a TXOP, and receiving a transmission during the duration. In another example, a method includes obtaining access to a WLAN channel during a transmission period of a coexisting cellular connection and providing a protection frame to defer transmissions from another device for a duration corresponding to at least a portion of a TXOP. In another example, a method includes determining a shift of a BT transaction based at least in part upon a schedule of cellular communications and shifting at least a portion of the BT transaction based upon the determined shift.

  • Patent number: 9137672
    Abstract: Aspects of a method and system for coexistence between 20 MHz and 40 MHz OBSSes in WLANs. Aspects of a system may include a receiving device, such as a WLAN station (STA), which enables reception of an information frame, such as a management frame, via a wireless communication medium. The receiving device may be associated with a wireless network device group, such as a basic service set (BSS). The information frame received by the receiving device may transmitted by a transmitting device, such as a transmitting access point (AP), which is associated with a foreign wireless network device group, for example a foreign BSS. The receiving device may be reconfigured to restrict RF channel bandwidth utilized for transmitting and/or receiving signals via the wireless communication medium based on the received information frame.
