摘要： This disclosure describes systems, methods, and devices related to adaptation of secure sounding signal. A device may determine a negotiated bandwidth to be used when communicating with a first station device. The device may determine a first bit stream used to generate a cyclic shift diversity (CSD) value based on the negotiated bandwidth, wherein a first number of bits is used for the first bit stream when a first negotiated bandwidth is used, and wherein a second number of bits is used for the first bit stream when a second negotiated bandwidth is used. The device may determine a second bit stream used to generate a random phase. The device may determine a secure a long training field (LTF) based on a combination of the first bit stream and the second bit stream. The device may cause to send a frame to the first station device, wherein the frame comprises the secure LTF.

摘要： 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.

摘要： For example, a wireless communication device may be configured to disable a per-antenna Cyclic Shift Diversity (CSD) insertion for a Long Training Field (LTF) of a Physical Layer (PHY) Protocol Data Unit (PPDU), for example, based on a determination that the PPDU is to be configured for a predefined type of channel-sounding-based measurement. For example, the per-antenna CSD insertion may include insertion of a CSD between a plurality of transmit chains of the wireless communication device. For example, the wireless communication device may be configured to transmit the LTF of the PPDU via the plurality of transmit chains with the per-antenna CSD insertion disabled.

The first user device may receive a request frame from the second user device based at least in part on transmitting the NAN service discovery frame, wherein the request frame comprises a request for ranging or location information from the first user device. The first user device may receive a NAN service discovery frame from the second user device, wherein the NAN service discovery frame comprises a request for ranging or location information from the first user device. The first user device may transmit a response frame comprising the ranging or location information in response to the received request frame.
