    Abstract: A system and method for peer-to-peer communications is disclosed. A first wireless device receives a message from a second wireless device identifying communication requirements of a point-to-point communication involving the second wireless device. The first wireless device determines whether the second wireless device's communication requirements can be satisfied based on communication resources already committed for other communications. When the communication requirements of the second wireless device can be satisfied, the first wireless device generates a time sharing schedule to be used by the first and second wireless devices based on the already-committed communication requirements and the second device's communication requirements. The time sharing schedule may include a first portion for broadcast communication among a group of devices to which the first and second wireless devices belong, and a second portion for the point-to-point communications of the second wireless devices.

    Abstract: Disclosed are systems and methods to modify the Bluetooth mono HFP protocol to support bi-directional stereo operation for high bandwidth audio including 12-KHz wide-band, 16-KHz super wide-band (SWB), and 24-KHz full band (FB) audio. The techniques leverage the larger packet size and longer duty cycle of the 2-EV5 transport packet and expand the block size of the audio frames generated by the AAC-ELD codec to increase the maximum data throughput from the 64 kbps of the mono HFP protocol to 192 kbps using a stereo HFP protocol. The increased throughput not only supports stereo operations, but allows the transport of redundant or FEC packets for increased robustness against packet loss. In one aspect, the AAC-ELD codec may be configured for dynamic bit rate switching to flexibly perform trade-offs between audio quality and robustness against packet loss. The stereo HFP may configure the maximum throughput based on the desired audio quality.

    Abstract: A system and method for routing communication to a common audio output device connected to each of two or more audio signal source devices. For each of the two or more audio signal source devices, a set of inputs are assessed. The set of inputs include: an operational state of the audio signal source device, an activity the audio signal source device, an audio-producing application being executed by the audio signal source device, and a degree of user activity with the audio-producing application being executed by the audio signal source. At a point in time, an audio routing score is generated for each of the two or more audio signal source devices according to a weighted calculation of the set of inputs based on the assessing. Finally, an audio signal routing decision is made, to route an audio signal from one of the two or more audio signal source devices to the audio output device, based on the audio routing score for each of the two or more audio signal source devices.

    Abstract: A method performed by a first electronic device that is communicatively coupled to a wireless headset, the method includes, while engaged in a call with a second electronic device, communicating with the wireless headset via a bi-directional wireless audio connection; determining that a joint media playback session has been initiated in which the first and second electronic devices are to independently stream media content for separate playback by both of the first and second electronic devices while engaging in the call; and switching to communicate with the wireless headset via a uni-directional wireless audio connection based on a determination of one or more capabilities of the wireless headset, wherein a mix of 1) one or more signals associated with the call and 2) an audio signal of the media content is transmitted to the wireless headset over the uni-directional wireless audio connection.

    Abstract: A method performed by an audio source device. The method receives a first audio signal and a second, different audio signal and encodes the first audio signal and the second audio signal, wherein the first audio signal is encoded differently than the second audio signal. The method generates a first data packet that comprises the first encoded audio signal and a first volume level and a second data packet that comprises the second encoded audio signal and a second volume level, wherein the first volume level is lower than the second volume level and transmits, over a wireless connection, the first and second data packets as a dual audio stream to an audio output device.
