Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for fast role switching between master and slave roles among wireless nodes. In one aspect, wireless nodes, such as wireless earbuds, coupled to a wireless source, may dynamically and intelligently swap master and slave roles to optimize battery life in the wireless nodes.

Abstract: Methods, systems, and devices for wireless communications are described. A device may break down (e.g., filter) a frequency band of an input signal into various subbands, and an encoding stage may then allocate bits across the various subbands. In some examples, the encoding stage may allocate proportionally more bits to higher prioritized (e.g., lower frequency) subbands. Once the subbands have been encoded, the output of each individual encoder (e.g., each encoded subband) may be transmitted in a packet. As such, subbands transmitted as single packets (e.g., subbands transmitted in individual packets) may be shorter in length and may be more efficiently prioritized by a transmitter and a receiver. For example, subbands may be prioritized based on a location where the most data is found in audio, based on the tone of a speaker (e.g., for speech encoding), etc.

Abstract: A first device may establish, with a second device, a first logical link associated with short-range communications. The first device may detect the transmission of a first packet from a master device to the second device carried on a second logical link. The first device may decode at least part of the first packet comprising data intended for the first device. The first device may transmit, to the second device, a request for a re-transmission of the first packet when the first device fails to decode at least part of the first packet. The first device may receive, from the second device, at least one re-transmission of the first packet. The first device may apply an error correction operation on the at least one re-transmission of the first packet received from the second device and the first packet received from the master device.

Abstract: A method for communication by a scanner is described. The method includes receiving a broadcast message from a broadcasting device in a connectionless mode. The method also includes performing back channel communication with the broadcasting device on a contention basis while maintaining the connectionless mode. The scanner may send a packet to the broadcasting device while maintaining a connectionless relationship with the broadcasting device.

Abstract: A method for wireless communication by an advertising Bluetooth (BT) device is described. The method includes detecting an energy level that indicates a corrupt connection request sent by a remote BT device. The method also includes determining that there is a failed connection attempt based on the corrupt connection request. The method further includes performing connectable advertising at a faster rate to allow the remote BT device to reconnect quickly.

Abstract: A device includes a memory configured to store instructions and one or more processors configured to execute the instructions to receive a media packet and to determine, based on a field of the media packet, whether the media packet includes motion data. The one or more processors are also configured to execute the instructions to, based on the media packet including motion data, extract the motion data from the media packet.

Abstract: Methods, systems, and devices for techniques for dynamically adjusting retransmission opportunities within a connected isochronous stream (CIS) are described. In some aspects, a first wireless device and a second wireless device may support one or more dynamic or “on-the-fly” adjustments to one or more CIS settings in accordance with a link quality between the first wireless device and the second wireless device. For example, the first wireless device and the second wireless device may tie a number of transmission opportunities that are usable for retransmissions, within a given isochronous (ISO) interval, to the link quality between the first wireless device and the second wireless device. The link quality may be tied or associated with a modulation and coding scheme (MCS) of the link. As such, the first wireless device and the second wireless device may tie a dynamic change in MCS to a dynamic change in retransmission opportunities.

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: Two devices (e.g., two wireless Bluetooth earbuds) may exchange device address information (e.g., Bluetooth address information) and may identify a primary address. When either of the devices connect to a source device (e.g., a phone), the primary address may be used by the connecting device such that the pair of devices appear as a single device (e.g., a Bluetooth-pairable device) to the source device, regardless of the device connecting to the source device as the primary device. The primary device may then send identity information (e.g., that has been exchanged with the secondary device) to the source device, such that the source device may connect to either of the two devices. Further, once a primary device connects to the source device, the primary device may transmit, to the secondary device, connection information such that the secondary device may connect to the source device and operate in the primary role.
