Abstract: Embodiments of the present invention provide secure ranging measurements for wireless devices in multi-user (MU) mode. Specifically, a signaling procedure between an initiating wireless station (ISTA) and a responding wireless station (RSTA) is used to enable protection of randomized LTF sequences used in the secure ranging measurements. The signaling procedure may be performed in a HEz or VHTz mode and may include performing error recovery when operating in the HEz mode.
