  • Patent number: 11039306
    Abstract: Methods, apparatuses, and computer readable media for location measurement reporting in a wireless network are disclosed. An apparatus of an initiator station (ISTA), where the apparatus comprises processing circuitry configured to decode a null data packet (NDP) announce (NDPA) frame from an initiator station (ISTA), the NDPA frame comprising a dialog token and an identification of a temporary key. The processing circuitry may be further configured to decode a first NDP from the ISTA, the NDP comprising first long training fields (LTFs), and wherein the NDP is received on a channel and encode a second NDP, the second NDP comprising second LTFs, wherein the second LTFs are determined based at least on the temporary key. The processing circuitry may be further configured to encode a location measurement report (LMR), the LMR comprising the dialog token and an indication of the temporary key.

  • Publication number: 20190182674
    Abstract: 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.
