Patent number: 11558155Abstract: 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.Type: GrantFiled: March 10, 2020Date of Patent: January 17, 2023Assignee: QUALCOMM INCORPORATEDInventors: Joel Linsky, Mayank Batra, Robin Heydon, Brian Redding

Patent number: 11375578Abstract: 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.Type: GrantFiled: January 17, 2019Date of Patent: June 28, 2022Assignee: QUALCOMM INCORPORATEDInventors: Mayank Batra, Joel Linsky, Robin Heydon, Brian Redding, Laurence George Richardson

Publication number: 20220078609Abstract: Certain aspects of the present disclosure provide techniques for secure digital key derivation for a ranging session between a first device (e.g., a user equipment (UE)) and a second device (e.g., a vehicle). According to certain aspects, a first device maintains a secure ranging in a secure element (SE) at the first device. The first device further fetches, from the SE, one or more other keys derived from the secure ranging key. The first device further uses the one or more other keys to secure a ranging session between the first device and a second device.Type: ApplicationFiled: April 23, 2021Publication date: March 10, 2022Inventors: Pierre-Francois APPIETTO, Charles Nung LO, Brian A.

Patent number: 10834154Abstract: This disclosure provides methods, devices and systems for signaling modulation schemes and stream parameters such that the modulation schemes and stream parameters can be adapted dynamically while maintaining an existing wireless connection. Some implementations include signaling, via a first channel, a set of stream parameters that govern communications on a second channel when a particular modulation scheme is used to modulate the packets transmitted via the second channel. A transmitting device may select a respective set of stream parameters for each of multiple modulation schemes. For example, in addition to an initial modulation scheme and set of stream parameters, the transmitting device can select alternative modulation schemes and sets of stream parameters that are optimized for the respective modulation schemes. The transmitting device signals the modulation schemes and the respective sets of stream parameters via the first channel in advance of switching modulation schemes for the second channel.Type: GrantFiled: April 17, 2019Date of Patent: November 10, 2020Assignee: QUALCOMM IncorporatedInventors: Brian Redding, Joel Linsky, Robin Heydon

Patent number: 10367609Abstract: As many applications, such as wireless headsets used with cellular phones, require mostly error free data to accurately reproduce a telephone conversation, uncorrected erroneous data packets may impact a perceived quality of a given application. The error correction techniques of the present disclosure promote error-correction in communication systems that lack FEC with respect to one or more portions of a data packet. The techniques therefore provide error correction for the entire packet, including those portions not protected by any imbedded error correction mechanism. As a result, data communications over noisy communication mediums may be improved as the techniques may reduce bit error rates, and increase the sensitivity of the receiving device such that the transmission power of a data packet may be reduced. For voice packets or other streaming data packets, the techniques promote improved audio quality over systems that do not employ the techniques described in the present disclosure.Type: GrantFiled: September 20, 2017Date of Patent: July 30, 2019Assignee: QUALCOMM IncorporatedInventors: Joel Linsky, Robin Heydon, Brian Redding

Publication number: 20190090287Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may establish a non-proprietary short-range link layer connection with a second device. The apparatus may establish a proprietary link layer connection with the second device. The apparatus may determine a duration of a previous non-proprietary link layer connection event. The apparatus may determine a number of proprietary link layer control PDUs to be exchanged during a proprietary connection event based at least in part on the duration of the previous non-proprietary link layer connection event and a start time of a subsequent non-proprietary link layer connection event. The apparatus may perform a proprietary control procedure by exchanging the number of proprietary link layer PDUs with the second device during the proprietary connection event.Type: ApplicationFiled: September 19, 2017Publication date: March 21, 2019Inventors: Brian REDDING, Robin HEYDON, Joel LINSKY

Publication number: 20190090081Abstract: Using the modulation scheme and/or coding techniques of traditional BLE may limit not only the data rate, but also limit the amount that the transmit power of a BLE air interface packet can be reduced due to receiver sensitivity. Namely, the lowest signal power level from which a receiving device may obtain information without meeting a BER threshold may limit the amount that the transmit power at the transmitter side can be reduced. There exists a need to transmit a BLE air interface packet using a modulation rate that is greater than 1 Mbps or 2 Mbps, enables a further reduction in transmit power, and/or enables an increase in receiver sensitivity. The present disclosure provides a solution by applying a coding technique and a PSK modulation scheme to a BLE air interface packet that increases data rate and reduces the sensitivity of the receiving device as compared to traditional BLE.Type: ApplicationFiled: September 19, 2017Publication date: March 21, 2019Inventors: Robin HEYDON, Joel LINSKY, Le LUONG, Koorosh AKHAVAN, Brian REDDING

Publication number: 20190089738Abstract: The apparatus may establish a non-proprietary link layer connection with a second device. The apparatus may determine if a first set of empty non-proprietary link layer PDUs are exchanged with the second device via one or more channels during a non-proprietary link layer connection event. The apparatus may exchange proprietary establishment PDUs with the second device during at least one proprietary link establishment event via the one or more channels when it is determined that the first set of empty non-proprietary link layer PDUs are exchanged with the second device via the one or more channels. The apparatus may establish a proprietary link layer connection with the second device when it is determined that a sequence of the proprietary establishment PDUs have been exchanged with the second device. The apparatus may communicate with the second device via the proprietary link layer connection.Type: ApplicationFiled: September 20, 2017Publication date: March 21, 2019Inventors: Brian REDDING, Robin HEYDON, Joel LINSKY
