Publication number: 20240106689Abstract: Systems and methods for low power wireless device detection are provided. In one or more implementations, a transmitting/advertising device may include a device identifier and/or one or more time-offset bits in a wireless communication frame for a scanning/receiving device. The scanning/receiving device may perform sequence-level correlation operations to detect the presence of the transmitting/advertising device. The sequence-level correlation operations may detect the transmitting/advertising device based on a detection of a correlation signal peak corresponding to the device identifier, and/or based relative timing of the correlation signal peak corresponding to the device identifier and a correlation signal peak corresponding to another item in the wireless communication frame.Type: ApplicationFiled: August 25, 2023Publication date: March 28, 2024Inventors: Lei LI, Camille CHEN, Siegfried LEHMANN, Yuelin MA

Patent number: 11849472Abstract: Methods and apparatuses are presented to facilitate coexistence between multiple wireless communication protocols implemented by a wireless communication device, by dynamically adjusting priority between the two protocols. The wireless communication device may typically favor a first protocol (e.g. Bluetooth/BTLE), prioritizing resource requests by the first protocol. In certain use cases, the first protocol may demand high resource usage for an extended time, particularly for newer tracking and wearable devices, such as location tags, watches, headsets, etc. Such applications can disrupt existing use cases for a second protocol (e.g., Wi-Fi). Therefore, the wireless communication device may dynamically determine whether the second protocol is performing critical operations, such as latency-sensitive applications or high-performance operations. If so, the wireless communication device may allocate resources accordingly in real time, e.g.Type: GrantFiled: May 13, 2021Date of Patent: December 19, 2023Assignee: Apple Inc.Inventors: Nohee Ko, Camille Chen, Kenneth Victa, Sanjay Mani, Balaji Ravindran, Yang Yu

Patent number: 11553506Abstract: A mobile computing device is configured to dynamically aggregate wireless communications on a common antenna. The device determines that a WiFi communication in a first frequency band is associated with an antenna, the WiFi communication having a number of assigned transmission time slots. The device determines that a second wireless communication in a second frequency band also is associated with the antenna, and determines a periodicity and/or a media quality of the second wireless communication. Based on the periodicity and/or media quality of the second wireless communication, the device aggregates the WiFi communication and the second wireless communication, the aggregation comprising assigning a number of packets of the second wireless communication to an aggregation frame of a plurality of frames associated with the transmission time slots assigned to the WiFi communication.Type: GrantFiled: July 10, 2020Date of Patent: January 10, 2023Assignee: APPLE INC.Inventors: Camille Chen, Nohee Ko, Sanjay Mani, Sudhanshu John, William F.

Patent number: 11516822Abstract: Methods and apparatuses are presented to facilitate coexistence between multiple wireless communication protocols implemented by a wireless communication device, using a shared antenna, e.g., due to limitations resulting from a small form factor of the wireless communication device. The wireless communication device may determine whether communications according to a second protocol are causing performance of communications according to a first protocol to fall below a threshold level. If so, the wireless communication device may operate in a mode that favors communications according to the first protocol. If not, the wireless communication device may operate in a mode that favors communications according to the second protocol. For example, the mode that favors communications according to the first protocol may include temporarily implementing operations to remedy the poor performance of the communications according to the first, e.g.Type: GrantFiled: September 10, 2019Date of Patent: November 29, 2022Assignee: Apple Inc.Inventors: Camille Chen, Akshay Tumkur Rajshekhar, Arjun Dheer, Gordon Kin, Sanjay Mani, Yang Yu, Tahir Shamim

Patent number: 11095664Abstract: A mobile device receives an invitation to commence a media session. The invitation may be from a legitimate caller or from a spoofing caller. The mobile device checks parameters using templates to evaluate a consistency of the invitation with respect to a database in the mobile device. The templates include session protocol, network topology, routing, and social templates. Specific template data includes standardized protocol parameters, values from a database of the mobile device and phonebook entries of the mobile device. Examples of the parameters include capabilities, preconditions, vendor equipment identifiers, a hop counter value and originating network information. The originating network information may be obtained from the database by first querying an on-line database to determine a network identifier associated with caller identification information in the invitation.Type: GrantFiled: April 5, 2017Date of Patent: August 17, 2021Assignee: Apple Inc.Inventors: Shi Lu, Camille Chen, Wenping Lou, Wen Zhao
