In this contribution, we would like
to
consider
Sensing and Ranging in
IMMW.
•
Some general design consideration are given.
Definition
IMMW
[4]
Motivation
•
Sensing and Ranging for IMMW
₋
Feature
: Similar as 802.11bf/az/bk for WLAN, Sensing and
Ranging also could be the
unique/highlight features
in
IMMW
₋
Market
: Based on the addressable market for WLAN
Sensing [8], Sensing and Ranging could further
enable the
commercialization
of IMMW
•
IMMW for Sensing and Ranging
₋
Requirement
:
Some use cases may
need mmWave
, e.g.,
For Sensing: Audio with user tracking, fine-grained gesture recognition, etc. [7, 8]
For Ranging: Device Proximity Detection, Nano Location in store, etc. [9]
₋
Current
: standardized mmWave Sensing and Ranging is
based on 11ad/ay
₋
Potential
:
IMMW
may be a good candidate (Unified
baseband for sub-7GHz and mmWave) to
supplement
the
mmWave part, with
higher commercialization possibility
.

[5]
802.11bf have well defined protocol for Sensing, no need to completely redesign
Minimize redesign according to IMMW architecture
Sensing (Sub-7GHz): Consider as baseline; DMG sensing (60GHz): Consider as reference
Consider as
baseline
No need to

Need to redesign IMMW
sensing and only take
DMG sensing as
reference, but not revise
based on DMG sensing

reference
, but not revise
based on DMG sensing

doc.: IEEE 802.11-24/0723r1 May 2024 Definition WLAN Sensing (802.11bf) [1] WLAN sensing is the use of received WLAN signals to detect feature(s) of an intended target(s) in a given environment. Features = Range, velocity, angular, motion, presence or proximity, gesture, etc. Target = Object, human, animal, etc. Environment = Room, house, car, enterprise, etc. WLAN Ranging (802.11az/bk) [2, 3] A Station to identify its absolute and relative position to another station or stations it s either associated or unassociated with. Better accuracy with respect to the Fine Timing Measurement (FTM) protocol.
