    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: 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.
