Abstract: 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.

Abstract: This disclosure describes systems, methods, and devices related to a trigger-based null data packet (NDP) for channel sounding system. A device may send a trigger frame to a group of station devices, the group of station devices including a first station device, the trigger frame indicating a high efficiency (HE) long training field (HE-LTF) mode and a guard interval duration. The device may identify a HE trigger-based (TB) null data packet (NDP) received from the first station device, the HE TB NDP including a first packet extension field, wherein the HE TB NDP is associated with the HE-LTF mode and the guard interval duration indicated in the trigger frame. The device may send a downlink NDP including a second packet extension field, a second HE-LTF mode, and a second guard interval duration. The device may determine channel state information based on HE TB NDP received from the first station device.

Abstract: This disclosure describes systems, methods, and devices related to enhanced ranging. A device may initiate a ranging sequence by transmitting an NDPA frame followed by an I2R NDP frame. The device may receive a corresponding R2I NDP frame and an R2I LMR from a responding station. The device may repeat the ranging sequence for two or more iterations to collect multiple data sets. The device may process the R2I NDP frame and the R2I LMR to generate continuous ToA and ToD measurements for each iteration.

Abstract: This disclosure describes systems, methods, and devices related to SpectrumAware-P2P. A device may identify a frame received an access point (AP) comprising one or more fields carrying information associated channel access during a peer-to-peer (P2P) communication with a first P2P device. The device may extract a channel and maximum power information element (IE). The device may initiate the P2P communication with the first P2P device based on the channel and maximum power IE.

Abstract: 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.
