Abstract: The disclosure relates generally to wireless communication, and more particularly to selective relay of data packets. A method includes receiving one or more received data packets from a series of transmitted data packets that are transmitted from a host device over a host piconet during a plurality of listening time slots of the host piconet; receiving a bitmap over a primary/secondary piconet, wherein the bitmap includes a plurality of bitmap portions and each bitmap portion respectively corresponds to one of the plurality of listening time slots of the host piconet; analyzing the received bitmap to identify one or more missed data packets from the series of transmitted data packets that were not received from the host device; and generating a relay list of missed data packets based on the analyzing of the bitmap.

Abstract: Apparatus, methods, and computer-readable media for an error correction technique that identifies transmission errors and corrective actions to maintain a link are disclosed herein. An example method of wireless communications includes receiving a first PDU comprising at least one of a SEQN bit or a packet counter value. The example method includes determining whether a value of the SEQN bit of the received first PDU is an expected SEQN or an unexpected SEQN. The example method includes calculating a MIC of the received first PDU. The example method includes determining whether the received first PDU is a re-transmission of a previous PDU or the received first PDU comprising errors. The example method includes transmitting an ACK or a NACK in response to the determination of whether the first PDU is the re-transmission of the previous PDU or the first PDU comprising errors.

Abstract: Systems and methods for network coordination are disclosed. A method comprises listening to a primary device during a receiving slot group of a primary/secondary (P/S) piconet shared between the primary device and the secondary device, determining based on the listening during the receiving slot group whether the primary device is attempting to communicate with the secondary device, listening to a host device on a host piconet during a transmitting slot group of the P/S piconet in response to a determination that the primary device is not attempting to communicate with the secondary device, and transmitting to the primary device over the P/S piconet during the transmitting slot group of the P/S piconet in response to a determination that the primary device is attempting to communicate with the secondary device.

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: The disclosure relates to performing a reliable broadcast from a source device to a plurality of nodes. In an aspect, a representative node establishes a first wireless communication link with each of one or more non-representative nodes, receives, from each of the one or more non-representative nodes, information indicating an ability of the one or more non-representative nodes to sniff wireless communications, establishes a second wireless communication link with the source device, configures the second wireless link based on the information received from the one or more non-representative nodes, sends control information for the second wireless communication link to each of the one or more non-representative nodes, and receives communications from the source device over the second wireless communication link, wherein the one or more non-representative nodes sniff the communications on the second wireless communication link based on the control information for that link.

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: 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.
