IEEE 802.11-21/1321r1 WLAN Sensing Procedure Proposal
This document by Solomon Trainin from Qualcomm presents a proposal on aligning the SFD for the WLAN sensing procedure. It aims to resolve contradictions, optimize behavior, and introduce a structured WLAN sensing procedure. The content outlines phases, terminology, setup, measurement, and reporting aspects to enhance the efficiency of the sensing process.

August 2021 doc.: IEEE 802.11-21/1321r1 Abstract A proposal on how to align the SFD and to be ready to draft the spec Submission Slide 2 Solomon Trainin, Qualcomm
August 2021 doc.: IEEE 802.11-21/1321r1 General 1. Resolve contradictions in the existent SFD text 2. Comment on Introduce the entire WLAN Sensing procedure Organize the procedure, setup, measurement, and reporting Present an example of the timeline 3. Optimize behavior avoid excessive link accesses Submission Slide 3 Solomon Trainin, Qualcomm
August 2021 doc.: IEEE 802.11-21/1321r1 Very few about terminology We already have the WLAN sensing procedure keep it as a container of the entire behavior Phase is an atomic part, Atomic, this is the part that can no longer be divided. For example, there is no NDPA without NDP. The measurement is not a phase because it contains many parts, and we already have the measurement instance that pretends to cover multiple parts Example of phase: polling, NDPA sounding, TF sounding, reporting Submission Slide 4 Solomon Trainin, Qualcomm

TBD The polling on reporting phase in example 5 could be addressed to responders other than those involved in the sounding. TBD The reporting phase in example 5 may be separated from the sounding phases. TBD LTF security update Submission Slide 7 Solomon Trainin, Qualcomm
