Revised: Removed text describing functionality that is not specific to Passive Ranging. 117 9.6.7.38 42 Passive Location Measurements Report' in the 'Passive Location Measurement Report Action field format' is TBD. Define field. Revised: Defined Passive Location Measurement Report frame format. 118 9.6.7.38 42 Dialog Token' in the 'Passive Location Measurement Report Action field format' is TBD. Change to: The Dialog field should be set to the value of the Dialog Token corresponding to the reported measurement. Revised: Defined a Passive Location Dialog token and how it functions and is used. 119 11.22.6.1 44 Missing description for passive ranging in 'Overview' section. Before line 36 add: is also a variant mode of the FTM procedure that allows 'passive' STAs to listen in to the ranging between ranging ISTAs/RSTA. This mode enables these passive STAs to estimate their differential distance to pairs or sets of the ranging ISTAs/RTA. These differential distances can be used by the passive STAs to estimate their location. Revised: Added description and added section 11.22.6.1.3 RSTA centric Scheduling for HEz Passive Ranging operation overview.
120 11.2.6.1 45 Missing enumerated description for HEz Passive Ranging passive ranging in 'Overview' section. Add: (f) Hez PassiveAdd Ranging: Similar to HEz Ranging in c) above but with some modifications enabling 'passive' STAs to listen in the exchanges between the ISTAs and the RSTA, as well as between ISTAs. These passive STAs can use the measurements to estimate their differential distance to pair or subsets of the ISTAs/RSTA, enabling the passive STAs to estimate their location. Revised: Added section 11.22.6.1.3 RSTA centric Scheduling for HEz Passive Ranging operation overview 124 11.22.6.4.9.1 69 Incorrect section number reference '11.22.6.4.2'.

Accepted 126 1.22.6.4.9.1 69 Incorrect section number reference '11.22.6.4.8.3'. Change '11.22.6.4.8.3' to '11.22.6.4.9.3'. Accepted 127 11.22.6.4.9.1 69 References to 'HEz Type subfield' in the 'HEz Specific Parameters field' in the 'Initial Fine Timing Measurement Request Frame' seems unclear. Not finding the desctiption of this field. Add description of this subfield if missing or maybe add easier to find reference if we already have this description. Revised: Changed to 'Passive Location Ranging' and added that field to the HEz Specific Parameters field in an initial Fine Timing Measurement Request frame and described its function.
B0 B4 B5 B15 Max TOD Error Exponent Reserved Bits: 5 11 Figure 9-aaa – Format of Error field The maximum errors in the Time-Stamp values are represented using the function defined in Equation (9-x). (9-x) ,where F is the Max Error Exponent Emax is the maximum Time-Stamp error, respectively, in units of picoseconds The RID subfield contains the ranging AID of the STA that transmitted the NDP in question. When the STA that transamitted the NDP is the RSTA, i.e. the time-stamp is here a TOD time-stamp, then the RID subfield is set to zero. TGaz Editor: Insert Section ‘9.4.2.nnn Passive Location LCI Table as shown below: Insert the following sub-clause in section 9.4.2 as below: 9.4.2.nnn Passive Location LCI element The Passive Location LCI Table Report element, defined in Figure 9-ggg, is used by an RSTA to broadcast LCI data for the ISTAs participating in its Passive Location Ranging exchanges.

The RSTA LCI contains a Measurement Report element with Measurement Type field equal to LCI (see Table 9-118 (Measurement Type field definitions for measurement reports)), which indicates the LCI of the transmitting RSTA and includes the Z and Usage Rules/Policy subelement or indicates an unknown LCI (see 11.22.6.7 (LCI and Location Civic retrieval using FTM procedure)). The Late, Incapable and Refused bits in the Measurement Report Mode field are set to 0.The Co-Located BSSID List subelement is present in the Measurement Report element with Measurement Type field equal to LCI, when there is at least one other BSS which is co-located with the reporting BSS.
The ISTA LCI Reports field contains Number of ISTA LCI Reports ISTA LCI Report field fields defined as in Figure ISTA RID ISTA MAC ADDRESS ISTA LCI octets: 2 6 variable Figure 9-hhh – ISTA LCI Report field The ISTA RID subfield contains the ranging ID of the ISTA reported on. The ISTA MAC ADDRESS subfield contains the MAC address of the ISTA reported on. The ISTA LCI subfield is TBD. TGaz Editor: Insert Section ‘9.6.7.mmm Secundus RSTA Broadcast Passive Location Measurement Report frame format’ as shown below: Insert the following sub-clause in section 9.6.7 as below: 9.6.7.mmm Secundus RSTA Broadcast Passive Location Measurement Report format The Secundus Broadcast RSTA Passive Location Measurement Report is an Action No Ack frame of category Ranging. The Secundus RSTA Broadcast Passive Location Measurement Report frame is used to support the passive location ranging mechanisms of the FTM procedure described in 11.22.6 (Fine timing measurement (FTM) procedure). The format of the Secundus RSTA Broadcast Passive Location Measurement Report Action field is shown in Figure 9-ggg (Secundus RSTA Broadcast Passive Location Measurement Report Action field format). Category Public Action Number of ISTA Passive Location Measurement Reports ISTA Passive Location Measurement Reports Octets: 1 1 1 Variable 9-ggg Secundus RSTA Broadcast Passive Location Measurement Report Action field format The Category field is defined in 9.4.1.11 (Action field). The Public Action field is defined in 9.6.8.1 (Public Action frames). The Number of ISTA Passive Location Measurement Reports field indicates the number of following Passive Location ISTA to RSTA LMR report fields. The ‘ISTA Passive Location Measurement Reports’ field contains ‘Number of ISTA Passive Location Measurement Reports’ ‘ISTA Passive Location Measurement Report elements’. The ‘ISTA Passive Location Measurement Reports element’ is defined in Section 9.4.2.nnn ISTA Passive Location Measurement Report.
