摘要: This disclosure describes systems, methods, and devices related to long training field (LTF) sequence security protection. A device may determine a null data packet (NDP) frame comprising one or more fields. The device may determine a first long training field (LTF) and a second LTF, the first LTF and the second LTF being associated with a first frequency band of the NDP frame, wherein time domain LTF symbols of first LTF and the second LTF are generated using different LTF sequences. The device may determine a third LTF and a fourth LTF, the third LTF and the fourth LTF being associated with the a second frequency band of the NDP frame, wherein time domain LTF symbols of third LTF and the fourth LTF are generated using different LTF sequences. The device may cause to send the NDP frame to an initiating or a responding device. The device may cause to send a location measurement report (LMR) frame to the initiating or the responding device, wherein the LMR comprises timing information associated with the first frequency band and the second frequency band.

摘要: Embodiments of an access point (AP), station (STA) and method of sounding are generally described herein. The AP may transmit, during a transmission opportunity (TXOP), a trigger frame (TF) to indicate that an STA is to transmit an uplink sounding packet during an uplink sounding period of the TXOP. The AP may attempt to detect the uplink sounding packet during the uplink sounding period. If the uplink sounding packet is not detected during the uplink sounding period, the AP may transmit a recovery packet to cause other STAs to determine a busy condition during the uplink sounding period. If the uplink sounding packet is detected during the uplink sounding period, the AP may determine a channel estimate for the STA based at least partly on the uplink sounding packet.

摘要: Methods, apparatuses, and computer readable media for location measurement reporting in a wireless network are disclosed. An apparatus of a responder station (RSTA) is disclosed, the apparatus comprising processing circuitry configured to decode a null data packet (NDP) announce (NDPA) frame from an initiator station (ISTA), the NDPA frame comprising an indication of a temporary key and an identification of the RSTA. The processing circuitry further configured to decode a NDP from the ISTA, the NDP comprising long training fields (LTFs), the NDP received on a channel. The processing circuitry further configured to determine whether the NDP from the ISTA is consistent with the NDP being generated using a temporary key shared between the ISTA and RSTA based on a comparison of the channel estimates. The processing circuitry may be further configured to determine for authentication whether the indication of the temporary key was generated based on the temporary key.

摘要: This disclosure describes systems, methods, and devices related to passive location measurement in wireless communications. A device may perform a ranging measurement with a first device and a second device. The device may identify a first uplink (UL) location measurement report (LMR) received from the first device. The device may identify a second UL LMR received from the second device. The device may cause to send a first broadcast LMR comprising information associated with the ranging determination of the first device and the second device. The device may cause to send a second broadcast LMR comprising the measurement information carried in the first UL LMR and the second UL LMR.

摘要: This disclosure describes systems, methods, and devices related to enhanced feedback for secure mode wireless communications. A device may send a first null data packet (NDP) to a second device, and identify a second NDP received from the second device. The device may identify a location measurement report (LMR) received from the second device, the LMR including a first channel response indicative of a first arrival time of the first NDP at the second device and a first phase shift associated with the first NDP. The device may generate a second channel response indicative of a second arrival time of the second NDP at the device and a second phase shift associated with the second NDP. The device may determine that the first channel response does not match the second channel response, and may identify an attempted attack.
