摘要： This disclosure describes systems, methods, and devices related to enhanced feedback for secure mode wireless communications. A device may send a first null data packet (NDP) to a second device, and identify a second NDP received from the second device. The device may identify a location measurement report (LMR) received from the second device, the LMR including a first channel response indicative of a first arrival time of the first NDP at the second device and a first phase shift associated with the first NDP. The device may generate a second channel response indicative of a second arrival time of the second NDP at the device and a second phase shift associated with the second NDP. The device may determine that the first channel response does not match the second channel response, and may identify an attempted attack.

摘要： Methods, apparatuses, and computer readable media for report identification and power control for ranging in a wireless network are disclosed. An apparatus of a responding station (RSTA) is disclosed, where the apparatus comprises processing circuitry configured to perform ranging with a initiating stations (ISTAs) and maintain a separate sounding dialogue token for each of the ISTAs and transmit a corresponding sounding dialogue token for a ISTA in a trigger frame for ranging and sounding or a null data packet announcement (NDPA) frame, and in a responding to initiating location measurement report. Apparatuses of RSTAs and ISTAS are disclosed that perform power control management during non-trigger-based ranging.
