I have some comments on some of the resolutions that are proposed for motion. I will
be unable to attend today’s teleconf, so I will make them here and I request that they
please be discussed at the relevant point during the motion process, despite my absence.

I'm going to assume the motion will be on the stuff in r3, not the
stuff in r0.
I'm confused re CID 24457. I thought we had agreed to resolve this
during the last teleconf as follows:
Straw Poll (Suggestions for changes supporting CID 24457): Do you accept to resolve CID 24457 as Revised and change the following text:
l At 49.16 change "the 5 to 7.125 GHz bands" [sic] to "the 5 and 6 GHz bands”
Result: Y/N/A = 11/2/8
I continue to oppose the resolution shown for CID 24523. If
"the OM parameters that AP uses are not reliable for the STAs" then the feature is
useless and should be deleted entirely.
Also, for CID 24124 you need to delete the commas at the start too,
otherwise you get "These features can, improve the average throughput".
Finally, for CID 24458, since TB PPDUs are sent in response to triggering
frames, I think it would be better to say:
An HE STA that is a mesh STA shall not transmit a triggering frame.
For CID 24294:
- A design in which a parameter that is N/A is present is not “simple and clean”
- The baseline convention is to only pass in parameters that are applicable
(that is why we have conditions like “FORMAT is HE_TB” in the TXVECTOR table)
- The commenter's proposed change explicitly identifies how the issue
can be fixed in a "simple and clean" manner, and should be adopted
For CID 24498:
- Calling a parameter SCRAMBLER_INITIAL_VALUE when it does NOT contain
the scrambler initial value is, well, completely irrational
- There have been interop issues caused by the confusion between the
scrambler initial value and the (scrambled) value of the Scrambler
Initialization field, so it is even more important to make sure the
parameter naming is not misleading
- There are only 3 instances of the term, so there is no editorial
cost to fixing this
- I think a concern was expressed that SCRAMBLER_INITIALIZATION_FIELD itself
was misleading, because it's the value in that field after scrambling.
I am happy to change the proposed parameter name to
SCRAMBLED_SCRAMBLER_INITIALIZATION_FIELD to address that concern
Similarly for CID 24499, the issue is quite subtle and this has caused
interop issues. To minimise the chance of future interop issues,
a NOTE is more than justified.

• the following CIDs are deferred: 24552, 24311, 24400, 24401, 24352, 24348
For CID 24349, where it says "parameter STA-ID" it should be "parameter STA_ID".

CID 24054
As discussed during the last teleconf, there seems to be disagreement
as to whether a unicast 1SS Trigger frame will take a STA that supports
dynamic HT SMPS but not HE SMPS out of 1SS-only mode. We need to agree
on what the answer is here; we cannot leave this interop issue open.
It we agree that it does, then I suggest we make this clear by adding in the HE SMPS subclause:
NOTE—A non-AP HE STA in dynamic SM power save mode that does not support
HE dynamic SM power save and that receives an individually addressed Trigger frame
addressed to it behaves as described in 11.2.6 (SM power save).
Also,
The STA switches to the multiple receive chain mode if it responds to the Trigger frame addressed to it
is just duplication of "shall also enable its multiple receive chains if it responds to a
Trigger frame [that starts a frame exchange sequence] that satisfies the following conditions" above
and should be deleted. (Also "addressed to it" is weird -- a STA is
not, I hope, going to respond to a Trigger frame not addressed to it.)
I agree the baseline has this duplication too, and I will raise it in TGmd.

• the following CIDs are deferred 24248, 24249, 24250
- I don't think the resolutions to 24242 and 24243 make sense (see attached)
- "one of the following condition" needs to be "… conditions"
- For 24248, 24249, 24250 the terminology is all over the place (see attached).
Also some stuff is in a NOTE but needs to be normative (because it's
a definition)
- For the non-CID proposal at the end, why not delete "HE" in the first bullet
too? Looks inconsistent otherwise
- For 24147 you said you had added "HE" in "so that other STAs can benefit from features relying on BSS color"
but it's still missing
- For 24515 there are some editorials (see attached)
Thanks,
Mark
