The CID list is: 3002, 3037, 3038, 3046, 3048, 3049, 3050, 3051, 3052, 3053, 3054, 3055, 3073, 3162, 3204   Proposed changes in this document are with reference to TGbf D2.1.  Revisions: • Rev 0: Intitial version of the document • Rev 1: Updated resolution of CID 3048 • Rev 2: Updated resolutions of CIDs 3162, 3002, 3052  Oct 2023  doc.: IEEE 802.11-23/1773r2 Submission page 2 Stephan Sand, DLR  Proposed comment resolution Presented and discussed, no open discussion points Under discussion G/T must be satisfied comment  CID Commentor Cat Page Comment Proposed Change Resolution 3050 Robert Stacey T 134.31 "Sensing initiator" is used before definition. Define sensing initiator before first use here. Rejected  Subclause 3.2 (Definitions specific to IEEE Std 802.11) defines the sensing initiator. Hence the term has been defined before using it on P134L31. By not redefining the term, duplication is avoided and the spec text is kept concise.  3162 Alireza Raissinia T 134.60 Should the paragraph in P134 L60-65 be moved to section 11.55.1.4.2 which is to include behavior for "sensing measurement session for an unassociated STAs" as it seems relevant As per comment. This comment can also be considered editorial Revised  TGbf editor: Please move P134 L60-65 to the end of subclause 11.55.1.4.2 3002 Robert Stacey T 135.12 Use the verb "may" to indicate optionality. Also the sensing procedure is conditionally optional; dependent on HE or EHT support. Replace paragraphs 1-3 with the following: "A STA that is an HE STA or EHT STA may support the sensing procedure. A STA that supports the sensing procedure is referred to a sensing STA. A sensing STA has dot11SensingImplemented equal to true and shall set the Sensing field in the Extended Capabilities element to 1. A sensing STA supports the sensing procedure as both a sensing initiator and sensing responder." Revised  TGbf Editor: Please replace paragraphs 1-3 P135L12 to L19 with “A STA that is an HE or EHT STA may support the sensing procedure. A STA that supports the sensing procedure is referred to as a sensing STA. A sensing STA has dot11SensingImplemented equal to true and shall set the Sensing field in the Extended Capabilities element to 1. A sensing STA shall Oct 2023  doc.: IEEE 802.11-23/1773r2 Submission page 3 Stephan Sand, DLR  support the sensing procedure as both a sensing initiator and a sensing responder.” 3046 Robert Stacey T 137.01 The normative "may" identifies an implementation requirement and is thus inappropriate for the receive implementation that has no control over what is being sent. Change to "A non-AP STA receives an AP's sensing capabilities during the active or passive scanning procedure (see 11.1.4)." Revised  TGbf Editor: Please replace paragraph 1 P137L7-L9 with “A non-AP STA receives an AP’s sensing capabilities (see 9.4.2.26 (Extended Capabilities element) and 9.4.2.321 (Sensing Capabilities element)) as part of an active or passive scanning procedure (see 11.1.4 (Acquiring synchronization, scanning)).” 3048 Robert Stacey T 137.27 Inappropriate shall since it does not identify something that needs to happen in the implmenetation and because it is conditional on intent, which is not testable.  A requirement for an exchange is a vague requirement on two different implementions. Remove this statement. Revised  The normative behavior is in Subclause 11.55.1.3 P136L59-L65.   TGbf Editor: Please remove the sentence starting on P137L32. 3049 Robert Stacey T 137.31 The first sentence in this paragraph is nonsensical. How can a non-AP STA *establish* a sensing measurement session if the session is initiated by the AP? Its completely up to the AP. Is it that the non-AP STA is initiating the session? The second sentence seems unnecessary, since we have already Replace the paragraph with "A non-AP STA that is not associated with an AP initiates a sensing mesaurement session with that AP by sending a Sensing Measurement Query frame that includes a Sensing Capabilities element to that AP." Revised  The sentence contains the same information as the one starting on P142L43. A Sensing Measurement Query frame always contains a Sensing Capabilities element. To avoid duplication this sentence should be removed.  Oct 2023  doc.: IEEE 802.11-23/1773r2 Submission page 4 Stephan Sand, DLR  established that the Probe Response frame can be used to send sensing capabilities. Does sending a Probe Request frame with sensing capabilities perform some additional function (other that inform the AP of its capabilities)? The third sentence does not make sense since it is not clear how the non-AP STA suddenly became a sensing responder. See also CID 3053.  TGbf Editor: Please remove the sentence starting on P137L35. 3051 Robert Stacey T 137.54 A requirement to set a field a certain way to mean a certain thing is redunant since that is precisely what the field definition does in Clause 9. Meaning is assigned in Clause 9. Behavior is defined here. Remove this paragraph. Revised  TGbf Editor:  Please remove paragraph starting P137L58 3037 Robert Stacey T 138.06 Is a sensing measurement session the parameter agreement or is it the exchange of frames using the agreed parameters? It is defined as the former, but the statement at 142.32 seems to imply the latter. Define sensing messurement session as the exchange of frames under the agreed paramters and not as the agreed parameters. Change to "A sensing measurement session is the a set of sensing measurement exchanges that use operational parameters agreed to between a sensing initiator and sensing responder and identified by a measurement session ID." Revised  TGbf Editor: Please replace the paragraph starting on P138L10 with “A sensing measurement session is a set of sensing measurement exchanges that use operational parameters agreed to between a sensing initiator and sensing responder and is identified by a measurement session ID.” 3038 Robert Stacey T 138.09 A shall statement conditional on intent is not testable and thus not useful Change to "To start a sensing measurement session between a sensing initiator and sensing responder, the Revised  TGbf Editor: Please replace the sentence starting on Oct 2023  doc.: IEEE 802.11-23/1773r2 Submission page 5 Stephan Sand, DLR  sensing initiator sends a Sensing Measurement Request frame to the sensing responder." P138L14 with “To establish a sensing measurement session, the SME of a sensing initiator shall issue an MLME-SENSMSMTSESSION.request primitive that results in the transmission of a(#3026) Sensing Measurement Request frame from this sensing initiator to a sensing responder.” 3204 Xiandong Dong T 138.45 what is the the requested sensing measurement session parameters , define it, or change the name as sensing measurement parameters. as in comment Rejected  The “requested sensing measurement session parameters in the received Sensing Measurement Request frame” are  defined in subclause 9.6.7.49 and references therein. To avoid duplication and keep the spec text concise, the “requested sensing measurement session parameters” are not redefined here. 3055 Robert Stacey T 142.06 A state diagram should have states in the boxes and *events* on the arrows. Events being things like timer expiry, frame received. "Sensing measurement exchange(s) are running" is not an event and thus cannot trigger a state change. "SMS not established" is not an event. "SMS established" is not an event. Fix the diagram so that specific events (something that happens at a point in time) are identified for each arrow.

Revised   TGbf Editor: Please replace the paragraph on P142L38 with “An unassociated STA establishes a sensing measurement session for non-TB sensing measurement exchanges by transmitting a Sensing Measurement Request frame to the AP including a Non-TB specific element to set the parameters of the sensing measurement session.” 3053 Robert Stacey T 142.34 A shall statement conditional on intent is not testable and thus not useful Replace with "An unassociated non-AP STA solicits sensing measurement session establishment by sending a Sensing Measrement Query frame to the AP."
