    Abstract: The present disclosure provides a mechanism to perform a CSB burst mode between a master device and one or more slave devices. In CSB burst mode, the master device may broadcast more than one packet of data in a CSB interval, and hence, may use the time slots in a CSB interval more efficiently than while operating in traditional CSB mode. CSB burst mode of the present disclosure may be used to improve the latency and duty cycle of data transmissions, such as for example, broadcast audio. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine to broadcast a set of packets during a CSB interval, where the set of packets includes a plurality of packets. In some aspects, the apparatus may broadcast the set of packets during the CSB interval to a set of second nodes.

    Abstract: Methods, non-transitory processor-readable storage media, systems, and devices for provisioning devices associated with wireless identity transmitters. An embodiment method performed by a proximity broadcast receiver may include operations for receiving a broadcast message including a secure identifier from a wireless identity transmitter, transmitting to a central server a sighting message that includes the secure identifier and an identity of the proximity broadcast receiver, receiving from the central server a return message that includes identification information related to the received broadcast message and that is authorized to be distributed to the proximity broadcast receiver based on data stored on the central server, and provisioning a device associated with the received broadcast message based on the identification information from the received return message. The method may also include identifying a software source from the received return message, requesting the software from the identified software source, and installing the received software.

    Abstract: This disclosure describes a first slave device that transmits information to a second slave device indicating that a first data packet was improperly received from a master device, so that a corresponding data packet may be relayed from the second slave device to the first slave device. In an aspect, the second slave device may receive a first data packet followed by an indication that the first slave device improperly received the first data packet, where the second slave device is configured to relay the first data packet to the first slave device in response thereto. In another aspect, the second slave device may receive a request to listen for a separate data stream of the first slave device based on a first data packet being improperly received by the first slave device and transmit a second data packet of the separate data stream to the first slave device.

    Abstract: This disclosure provides methods, devices and systems for signaling modulation schemes and stream parameters such that the modulation schemes and stream parameters can be adapted dynamically while maintaining an existing wireless connection. Some implementations include signaling, via a first channel, a set of stream parameters that govern communications on a second channel when a particular modulation scheme is used to modulate the packets transmitted via the second channel. A transmitting device may select a respective set of stream parameters for each of multiple modulation schemes. For example, in addition to an initial modulation scheme and set of stream parameters, the transmitting device can select alternative modulation schemes and sets of stream parameters that are optimized for the respective modulation schemes. The transmitting device signals the modulation schemes and the respective sets of stream parameters via the first channel in advance of switching modulation schemes for the second channel. The transmitting device is enabled to change the modulation scheme and the set of stream parameters on the fly by including an indication of the modulation scheme in the next packet it transmits via the second channel.

    Abstract: As many applications, such as wireless headsets used with cellular phones, require mostly error free data to accurately reproduce a telephone conversation, uncorrected erroneous data packets may impact a perceived quality of a given application. The error correction techniques of the present disclosure promote error-correction in communication systems that lack FEC with respect to one or more portions of a data packet. The techniques therefore provide error correction for the entire packet, including those portions not protected by any imbedded error correction mechanism. As a result, data communications over noisy communication mediums may be improved as the techniques may reduce bit error rates, and increase the sensitivity of the receiving device such that the transmission power of a data packet may be reduced. For voice packets or other streaming data packets, the techniques promote improved audio quality over systems that do not employ the techniques described in the present disclosure.
