Abstract: This disclosure describes systems, methods, and devices related to antenna configuration parameters. A device may determine one or more antennas having one or more phases. The device may determine a first delay associated with a first antenna of the one or more antennas. The device may determine a second delay associated with a second antenna of the one or more antennas. The device may cause to send a frame to a first station device using the first antenna, wherein the frame comprises a first indication of the delay associated with the first antenna and a second indication of the delay associated with the second antenna.

Abstract: Some demonstrative embodiments include apparatuses systems and/or methods of ranging measurement. For example, an apparatus may include circuitry and logic configured to cause a first wireless communication station (STA) to receive from a second STA a sounding transmission for a range measurement of a range between the first STA and the second STA; to determine a channel response estimation based on the sounding transmission from the second STA; to determine a timing value based on the channel response estimation; and to transmit a feedback message to the second STA, the feedback message including the timing value.

Abstract: This disclosure describes systems, methods, and devices related to correlation reduction. A device may generate a sequence of pseudo-random symbols associated with a sounding signal to be transmitted to a first station device. The device may apply a modifier to the sequence of pseudo-random symbols. The device may generate a secure sounding signal from the modified sequence of pseudo-random symbols. The device may send the secure sounding signal to a first station device.

Abstract: The disclosure relates generally to method, system and apparatus to optimize wireless charging to identify a proximal Near-Field Communication (NFC) tag and prevent damage by a magnetic wireless charging field. The disclosed embodiment provide different methods for NFC tag detection without impacting A4WP wireless charging. In an exemplary method, dedicated NFC reader is used to interleave the NFC and A4WP signals on the same coil. In one implementation the signals are frequency-multiplexed. In another implementation, the signals are time-multiplexed.

Abstract: The present disclosure relates to computer-implemented systems and methods for facilitating simultaneous poll responses. A method may include assigning respective subsets of subcarrier frequencies to a plurality of user devices for communication over a wireless channel. The method may also include transmitting, simultaneously, a channel status request poll to the user devices. Additionally, the method may include determining, based at least in part on a first channel status response received via a first subset of subcarrier frequencies over the wireless channel, that the first channel status response is received from the first user device. Similarly, the method may also include determining a second channel status response is received from a second user device. Furthermore, the method may include determining, based at least in part on the first channel status response and the second channel status response, to schedule simultaneous data communication for the first device and the second device.
