  • Publication number: 20250097830
    Abstract: Techniques for using contextual information from a host STAs in the context of a wireless network having at least one non-AP station (STA) are disclosed. The host STA uses transmitted fields from the AP to determine a make of the AP. The host STA sends a request message to control one or more AP parameters to the AP. The host STA, if the AP accepts the message, sends another message identifying the STAs in its network. The host STA also acquires, via a message from the AP, details about the STAs associated with the AP. When receiving contextual information from itself or otherwise, the host STA determines an appropriate action, and transmits an action request message for the AP to take the action. The AP confirms once the action is taken.

  • Patent number: 12160298
    Abstract: A method includes receiving CSI frames among P CSI frames transmitted from another electronic device. The method includes estimating a CSI from each of the received CSI frames as an available CSI estimate.

The method includes compensating, via the impairment model, for the errors in amplitude and phase of P CSI estimates. Compensating for the errors in amplitude and phase of the P CSI estimates can be based on: approximating a missing CSI estimate based on the available CSI estimates; determining an AGC gain value; or computing the errors in the phase based on a weighted least-squares solution. The method includes estimating a breathing rate of a subject based on different spatial dimensions of the P compensated CSI estimates.
