Abstract: Methods, systems, and devices for real-time ACK/NACK are described. The method includes a primary wireless device receiving a transmission from a source wireless device over a wireless link established between the source wireless device and the primary wireless device, determining whether the primary wireless device correctly received a data packet during the transmission, determining whether a first indication of ACK is received from a secondary wireless device during a time gap after receiving the transmission from the source wireless device, the first indication associated with the transmission between the source wireless device and the primary wireless device, and sending a second indication of ACK or NACK to the source wireless device based on whether the primary wireless device correctly received the data packet and whether the first indication is received from the secondary wireless device during the time gap.

Abstract: Methods, systems, and devices for wireless communications are described. Described techniques may include broadcasting a first Bluetooth packet over a channel bandwidth during a first set of one or more master slots of a periodic broadcast window; performing one or more received signal strength indication (RSSI) measurements during a first set of one or more slave slot of the periodic broadcast window; receiving from one or more receiving devices, based at least in part on the one or more RSSI measurements, one or more negative acknowledgement (NACK) signals corresponding to the first Bluetooth packet; and rebroadcasting, during a second set of one or more master slots of the periodic broadcast window, the first Bluetooth packet based at least in part on the one or more NACK signals

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: Methods, systems, and devices for wireless communications are described. A device may receive a first packet including a set of segments. A segment of the set of segments may include a cyclic redundancy check (CRC). The device may determine a corruption of one or more segments of the first packet, and process the one or more segments based on the corruption. The device may receive a second packet based on the corruption of the one or more segments of the first packet. The second packet may include one or more of the segments of the first packet. The device may process the one or more segments of the first packet received in the second packet, and transmit a positive acknowledgment indicating a reception of all segments of the set of segments based on the first packet and the second packet.

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: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for receiving a first packet comprising a first sequence number (SEQN) and a second packet comprising a second SEQN, and obtaining a first hash for the first packet and a second hash for the second packet. The receiving device may classify the second packet as one of a new packet or a retransmission of the first packet based on a comparison between the first SEQN and the second SEQN and a comparison between the first hash and the second hash. The receiving device may selectively process the payload of the second packet based on the classifying.

Abstract: The disclosure relates generally to wireless communication, and more particularly to selective relay of data packets. A method includes listening to a host device in one or more listening time slots of a host piconet, identifying one or more bitmap portions of a bitmap, wherein the identified one or more bitmap portions corresponds to the one or more listening time slots of the host piconet, determining whether a data packet having a data packet payload is effectively received from the host device during the one or more listening time slots, and populating the bitmap with one or more corresponding signifiers.

Abstract: There is a need to enable a wireless device to output signals such that the natural instincts of the user may be triggered. The present disclosure provides a solution by enabling a wireless device to determine a time delay and intensity difference associated with an audio output at a subset output devices based at least in part on a perceived spatial placement of at least one signal, a position of the transmitting device, and/or a signal strength associated with the signal. Using the time delay and the intensity difference, the output devices farthest from the transmitting device may output the at least one signal using the time delay and the intensity difference such that the user may detecting differences in the sound wave's time of arrival and intensity at the left ear versus the right ear, and thus, perceive the location of the audio source.

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.
