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: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an example method may include generating, by a first device, a wake-up message, The method may include transmitting, by the first device, the wake-up message to a second device. Generating the wake-up message may include encoding an address associated with the second device into a plurality of packets. The length of each packet of the plurality of packets in combination may be representative of the address. At least two packets of the plurality of packets may vary in packet length by a multiple of a packet length variance value. The wake-up message may include the plurality of packets.

Abstract: Systems and methods are directed to discovering trusted remote devices and establishing trusted communications with trusted remote devices. A local device can determine one or more time periods of expected silence in a communication between the local device and a remote device; and embed trusted communication messages in the one or more time periods for at least one of: discovering that the remote device is a trusted remote device, performing a trusted communication with the trusted remote device. The communication may be based on a Bluetooth protocol in a link layer.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In certain implementations, the apparatus may determine a static security key associated with the Tx-only mesh node. In one aspect, the static security key may include a MIC. The apparatus may transmit the static security key to at least one mesh node using a first frequency channel. The apparatus may transmit at least one PDU to the at least one mesh node using a second frequency channel that is different than the first frequency channel.

Abstract: This disclosure provides systems, methods and apparatus for clear channel assessment (CCA) enabled narrowband (NB) communications. In some implementations, a device is configured to associate with an NB channel (such as a Bluetooth channel), perform a CCA to assess whether the NB channel is clear, and transmit on the NB channel when clear. If the NB channel is not clear, the device may prevent transmitting on the NB channel. The device may prevent avoiding the NB channel after the first time that the NB channel is not clear. If the NB channel remains not clear (such as over a number of CCAs for the NB channel), the device may avoid the NB channel by removing the NB channel for FH for an amount of time. In some implementations, the device may be configured to perform frame based equipment (FBE) CCAs for one or more NB channels.

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: According to various aspects and techniques to enable methods and systems for a first communication device to determine an approximate number of other communication devices that have lost contact with a host communication device. This includes determining a common future time window using a last known global time stamp and determining a transmit time within the common future time window. This also includes receiving samples that are captured during the common future time window on a predefined communication channel, as well as analyzing the received samples to estimate the total number of other communication devices.

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: The apparatus receives a plurality of broadcasted segmented messages from one or more nodes. Each segmented message of the segmented messages includes redundancy error coding. The apparatus reassembles the segmented messages into a plurality of PDUs. Each PDU of the plurality of PDUs has a sequence number. The apparatus determines that one or more PDUs of the plurality of PDUs failed to decode upon attempting to decode each of the PDUs, or that the one or more PDUs are missing from the plurality of PDUs based on the sequence number. The apparatus constructs at least one PDU of the one or more PDUs based on the redundancy error coding in decoded PDUs other than the at least one PDU. The apparatus reassembles the PDUs into an object based on the sequence number for each PDU.
