Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a secondary peripheral device may obtain microphone data. The secondary peripheral device may select a peripheral-to-central (P2C) slot, among P2C slots of an enhanced synchronous connection oriented (eSCO) interval, that occurs after a first P2C slot in the eSCO interval. The secondary peripheral device may transmit the microphone data to a primary peripheral device in the P2C slot. Numerous other aspects are described.

Abstract: Devices and methods for connected isochronous stream (CIS) swapping are disclosed. In an example Bluetooth™ setting, a smartphone can be connected to multiple earbuds. It is possible that both earbuds include microphones, but only one microphone is enabled at a given time. That is, only one of the CISes established between the smartphone and the earbuds is bidirectional, and the other is unidirectional. The disclosed techniques enable the CISes to be swapped between the earbuds so that the earbud with better microphone quality will have ownership of the bidirectional CIS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may receive a data packet on an isochronous (ISO) link. The wireless device may transmit a low energy (LE) packet with feedback for the data packet. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first peripheral device may receive, at a controller layer from a host layer, a command for information from a second peripheral device associated with the first peripheral device. The first peripheral device may provide, from the controller layer to the host layer, the information from local information stored at the first peripheral device. Numerous other aspects are described.

Abstract: This disclosure provides methods, devices, and systems for streaming media from a Bluetooth-enabled peripheral device to a WLAN device over a wireless link (such as a P2P link). In some instances, a first peripheral device of a pair of peripheral devices selects values of a time-to-play (TTP) and a sequence number of a first audio stream, and synchronizes the selected TTP and sequence number with a TTP and a sequence number of a second audio stream. The first peripheral device rate-converts first audio data using a sample rate conversion ratio based on the selected TTP and sequence number, encapsulates the rate-converted first audio data into first RTP packets, and transmits the first RTP packets to the WLAN device concurrently with a transmission of second RTP packets from the second peripheral device to the WLAN device.

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: A method, apparatus, and computer-readable medium are provided that improve power management for devices communicating via Bluetooth (BT) over Internet Protocol (BTOIP). The apparatus for wireless communication for a first device receives a first set of packets from a second device during a time period associated with a training phase for the first device. The apparatus determines an arrival time of a first packet of the first set of packets. The apparatus determines, based on the arrival time and a wakeup time interval, a wakeup time for the first device. The apparatus causes, based on the wakeup time for the first device and one or more attributes associated with the first set of packets, a shutdown of the first device.

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: A device includes a memory configured to store instructions and one or more processors configured to execute the instructions. The one or more processors are configured to execute the instructions to obtain link data corresponding to a communication link to a second device. The one or more processors are configured to execute the instructions to select, at least partially based on the link data, between an ambisonics mode and a stereo mode.

Abstract: In a wireless communications system, packet error rate may be relatively low (e.g., five percent). Accordingly, receivers may successfully receive a first transmission the majority of the time. However, bandwidth may be used for retransmissions, which may be used relatively infrequently. Because retransmission packets do not necessarily have to be the same as transmission packets, transmission packets may be given more weight than retransmission packets. For example, transmission packets may be encoded with a higher bitrate than retransmission packets. In aspects, a transmitter may send a first transmission packet, including first data encoded with a first bitrate, and send a second transmission packet, including second data encoded with the first bitrate. The transmitter may send a first retransmission packet that includes the first data encoded with a second bitrate and the second data encoded with the second bitrate, and the first bitrate may be higher than the second bitrate.
