Abstract: The disclosure provides some embodiments for securing long training field (LTF) sequence. A responding station (RSTA) configures a location management report (LMR) frame. The LMR frame is configured to include an LMR in respect of a previous measurement, and data to be used to generate a null data packet (NDP) for a current measurement that is to be performed following the previous measurement. The RSTA further encrypts the LMR frame using protected management frames (PMF) scheme, and transmits the encrypted LMR frame to an initiating station (ISTA) for generating an LTF sequence for the current measurement. In response to receiving an NDP announcement (NDPA) and an NDP for the current measurement from the ISTA, the RSTA generates an NDP for the current measurement based on the NDPA and the data using CCMP, and transmits the NDP to the ISTA.

Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of Multi-User (MU) ranging measurement. For example, an apparatus may include circuitry and logic configured to cause a wireless station to generate a plurality of sounding sequences corresponding to a plurality of stations (STAs), the plurality of sounding sequences including at least first and second different sounding sequences, the first sounding sequence corresponding to at least one first STA of the plurality of STAs, the second sounding sequence corresponding to at least one second STA of the plurality of STAs; during a Multi-User (MU) ranging measurement, to transmit a MU frame to indicate a MU Downlink (DL) transmission; and, following the MU frame, to transmit a MU DL Null Data Packet (NDP) transmission to the plurality of STAs, the MU DL NDP transmission including a plurality of Long Training Fields (LTFs) including the plurality of sounding sequences.

Abstract: This disclosure describes systems, methods, and devices related to enhanced fine timing measurement protocol negotiation. A device may identify an enhanced fine timing measurement request received from a first device, the enhanced fine timing measurement request comprising one or more information elements associated with one or more multiple-input multiple-output (MIMO) parameters. The device may cause to send an enhanced fine timing measurement response to the first device. The device may identify a null data packet announcement associated with a location determination of the first device. The device may identify a null data packet received from the first device. The device may cause to send a null data packet feedback to the first device.
