Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an assisting wireless device may track a first retransmission metric that is based on a number of retransmitted packets that the assisting wireless device received from a source device. The assisting wireless device may receive, from a sink wireless device, an acknowledgement assistance request indicating a second retransmission metric for the sink wireless device. The assisting wireless device may transmit, to the sink wireless device, a response to the acknowledgement assistance request based on respective values of the first retransmission metric and the second retransmission metric. 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 establish, with a user equipment (UE), a first connected isochronous stream (CIS), a second CIS, and a control channel for the first CIS and the second CIS, where the first peripheral device is configured to output audio signals for the first CIS and handle feedback for the first CIS. The first peripheral device may transmit, to a second peripheral device paired with the first peripheral device, an indication that the second peripheral device is to output audio signals for the second CIS and handle feedback for the second CIS. The first peripheral device may receive the first CIS, while maintaining the control channel for the first CIS and the second CIS. Numerous other aspects are described.

Abstract: Systems and methods for Bluetooth voice link shadowing are disclosed. A primary device may receive an eSCO packet from host device over master slot(s) of an enhanced synchronization connection oriented (eSCO) window within an interval of a host piconet shared between the host and primary devices. A secondary device may sniff for the eSCO packet also over master slot(s) of the eSCO window. When the primary device successfully receives the eSCO packet from the host, it may unconditionally relay the packet to the secondary device. Alternatively, it may conditionally relay the packet when the secondary device does not successfully sniff the packet. When the secondary device successfully sniffs the eSCO packet from the host, it may unconditionally relay the packet to the primary device. Alternatively, it may conditionally relay the packet when the primary device does not successfully receive the packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first peripheral device may receive audio stream packets sniffed from an owner audio stream assigned to a second peripheral device paired with the first peripheral device. The first peripheral device may receive a synchronization message from the second peripheral device that includes an owner packet bitmap that identifies packets in the owner audio stream. The first peripheral device may identify missed packets that the first peripheral device missed from the owner audio stream, based on a result of a comparison of the owner packet bitmap and a sniffer packet bitmap that identifies sniffed audio stream packets. The first peripheral device may transmit a response message indicating the missed packets. Numerous other aspects are described.

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: An apparatus may receive, from a second device over a first communications link, a first bitmap indicating a first set of packets received by the second device from a third device; determine a second bitmap indicating a second set of packets received by the first device from the third device, each of the first set of packets and the second set of packets comprising at least a fragment of a PDU; transmit, to the second device, information indicating a third set of packets based on the first bitmap and based on the second bitmap, the third set of packets being unsuccessfully received by the first device from the third device; and receive a fourth set of packets from the second device based on transmission of the information indicating the third set of packets, the fourth set of packets including information from the third set of packets.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a first device. The first device may decrypt a first packet using a first nonce associated with a first expected packet number. The first device may determine a next nonce based on the decryption of the first packet, wherein the next nonce is different when the first packet is unsuccessfully decrypted than when the first packet is successfully decrypted. The first device may decrypt a second packet received consecutive to the first packet based on the next nonce.
