  • Publication number: 20240106689
    Abstract: 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.

  • Patent number: 11849472
    Abstract: 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.

  • Publication number: 20230222076
    Abstract: Embodiments relate to an integrated circuit of an electronic device that coordinates activities with another integrated circuit of the electronic device. The integrated circuit includes an interface circuit and a processor circuit. The interface circuit communicates over a multi-drop bus connected to multiple electronic components. The processor circuit receives an authorization request from the integrated circuit via the interface circuit and the multi-drop bus. The received authorization request relates to authorization to perform an activity on the other integrated circuit. In response to receiving the authorization request, the processor circuit determines whether the other integrated circuit is authorized to execute the activity.

  • Patent number: 11553506
    Abstract: 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.

  • Patent number: 11516822
    Abstract: 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.

  • Patent number: 11147046
    Abstract: An interface circuit in an electronic device (such as an access point) may request a channel status in order to specify a subset of one or more frequency sub-bands. During operation, the interface circuit may provide at least a frame to the recipient electronic device, where the frame requests the channel status for the one or more frequency sub-bands. Then, the electronic device may receive one or more measurement results from the recipient electronic device that specify the subset of the one or more frequency sub-bands (such as one or more RUs) that are not to be used when communicating with the recipient electronic device.

  • Patent number: 11095664
    Abstract: 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.
