Publication number: 20240032122Abstract: 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.Type: ApplicationFiled: March 25, 2021Publication date: January 25, 2024Inventors: Benjamin CAMPBELL, Mayank BATRA, Ivan OAKES, Laurent WOJCIESZAK, Dishant SRIVASTAVA, Nitin Raghavendra KIDIYOOR, Vishal AGARWAL, Joel LINSKY, Douglas KOGAN

Patent number: 11375574Abstract: Reduced Advanced Audio Distribution Profile (A2DP) latency on a link between a source and a pair of headphones may be achieved by improving the quality of the link between secondary and primary and establishing a direct link between the source and secondary to mitigate the link quality issues of the source and primary link. In one example, this involves receiving, via a first receiver, packets from a source on a first wireless connection, determining, by the first receiver, that a first packet received via the first wireless connection has an error, establishing a second connection between the first receiver and a second receiver, and establishing a third connection between the second receiver and the source. In particular, the first receiver may be configured as a primary True Wireless Stereo (TWS) Bluetooth device and the second receiver may be configured as a secondary TWS Bluetooth device.Type: GrantFiled: August 11, 2020Date of Patent: June 28, 2022Assignee: QUALCOMM INCORPORATEDInventors: Dishant Srivastava, Benjamin Campbell, Joel Linsky, Mayank Batra

Patent number: 11216051Abstract: This disclosure provides systems, methods and apparatus for smart sockets in a communication network. A smart socket can be implemented to monitor one or more power quality characteristics of a power supply providing energy to the smart home environment. Smart sockets implemented to monitor power quality characteristics can sense when power fluctuations are present in the power supply, and shut down connected devices to prevent damage. A plurality of coordinating smart sockets can be implemented to optimize power utilization when the smart home environment is operating on backup power, during low electricity tariff periods, or when operating on a renewable energy source. The plurality of coordinating smart sockets can be implemented to autonomously schedule tasks based on a context of operation of other devices in the smart home environment. The plurality of coordinating smart sockets can be implemented to achieve configurable energy targets for the smart home environment.Type: GrantFiled: July 24, 2019Date of Patent: January 4, 2022Assignee: QUALCOMM IncorporatedInventors: Skanda Kumar Kaipu Narahari, Chirag Manojkumar Kharvar, Dishant Srivastava, Sourabh Jana, Jagdeep Kumar Hans

Patent number: 11115811Abstract: Two devices (e.g., two wireless Bluetooth earbuds) may exchange device address information (e.g., Bluetooth address information) and may identify a primary address. When either of the devices connect to a source device (e.g., a phone), the primary address may be used by the connecting device such that the pair of devices appear as a single device (e.g., a Bluetooth-pairable device) to the source device, regardless of the device connecting to the source device as the primary device. The primary device may then send identity information (e.g., that has been exchanged with the secondary device) to the source device, such that the source device may connect to either of the two devices. Further, once a primary device connects to the source device, the primary device may transmit, to the secondary device, connection information such that the secondary device may connect to the source device and operate in the primary role.Type: GrantFiled: April 4, 2019Date of Patent: September 7, 2021Assignee: QUALCOMM INCORPORATEDInventors: Mayank Batra, Robin Heydon, Ravi Shekhar, Srivathsa Sridhara, Dishant Srivastava, Steven Singer, Nicholas Jones, Benjamin Campbell, Richard Cardoe, Laurence Richardson

Patent number: 10979990Abstract: Methods, systems, and devices for wireless communications at a wireless audio device are described. A first (e.g., primary) wireless audio device may initiate a role switch procedure with a second (e.g., secondary) wireless audio device. The first wireless audio device may disable traffic flow between the source device and the first wireless audio device and transmit synchronization information and timing information necessary for taking over the role of primary wireless audio device to the second wireless audio device. The first wireless audio device may transmit a device role switch message, and the first wireless audio device and the second wireless audio device may perform the role switch. After performing the role switch, the first wireless audio device may assume the role of a secondary wireless audio device and the second wireless audio device may assume the role of a primary wireless audio device.Type: GrantFiled: May 23, 2019Date of Patent: April 13, 2021Assignee: QUALCOMM IncorporatedInventors: Dishant Srivastava, Steven Singer, Robin Heydon, Mayank Batra, Joel Linsky

Patent number: 10785818Abstract: A first Bluetooth audio device paired with a second Bluetooth audio device may coordinate communications between the two BT audio devices. The first Bluetooth audio device may originally communication with the second BT audio device over a first type of Bluetooth connection. When the first Bluetooth audio device determines that the second Bluetooth audio device has left or is close to leaving the range of the first Bluetooth audio device, the first Bluetooth audio device may switch to communicating with the second Bluetooth audio device over a second type of Bluetooth connection or over a wireless mesh network. The first Bluetooth audio device may maintain a Bluetooth connection of the first type with a mobile device regardless of how the first Bluetooth audio device communicates with the second Bluetooth audio device.Type: GrantFiled: September 20, 2018Date of Patent: September 22, 2020Assignee: QUALCOMM IncorporatedInventors: Srivathsa Sridhara, Ravi Shekhar, Dishant Srivastava

Patent number: 10779210Abstract: Methods, systems, and devices for wireless communications are described. One method may include determining that a quality condition of a primary Bluetooth-enabled device is lower than a quality condition of a secondary Bluetooth-enabled device. The primary Bluetooth-enabled device may transmit, to the secondary Bluetooth-enabled device, a handover request message based on the determining. The handover request message may include a subset of connection information associated with a connection between the primary Bluetooth-enabled device and a device in wireless communications with the primary Bluetooth-enabled device. The primary Bluetooth-enabled device may receive, from the secondary Bluetooth-enabled device, a handover response message based on the handover request message. As a result, the primary Bluetooth-enabled device may handover, to the secondary Bluetooth-enabled device, at least one logical transport channel of the set of logical transport channels based on the handover response message.Type: GrantFiled: January 3, 2019Date of Patent: September 15, 2020Assignee: QUALCOMM IncorporatedInventors: Dishant Srivastava, Mayank Batra, Steven Singer, Benjamin Campbell, Robin Heydon
