Re: [STDS-802-11-TGAX] Allowed puncturing patterns

> I don't think SP3 is necessary as it is clear that opt a enables no puncture in p80 but only secondary for case 7.

Unfortunately the spec is contradictory or at least very ambiguous on this.  For example, the following at 274.43 suggests you cannot have the P80 unpunctured in "case 7":

l) Transmit an HE MU PPDU with preamble puncturing in 160 MHz or 80+80 MHz where in the primary 80 MHz of the preamble only the primary 40 MHz is present

(Sentences with "only" always have a high risk of ambiguity and need to be worded with extreme care.)

I would like all three SPs to be run.  I am happy to be the proposer for whichever you do not wish to propose.

Thanks,

Mark

Lili has CID 24101 that covers SP2.  I don't mind who puts the SPs
forward; I'm happy to put them all forward.

In any case, it doesn't make sense to resolve these comments separately.
CIDs 24101, 24105, 24106, 24107, 24175 should all be resolved at the same time,
and I think they should be resolved by making the kinds of changes suggested
in http://www.ieee802.org/11/email/stds-802-11-tgax/msg01701.html (once
we've run the SPs to get the preferred direction).

I note that CID 24105 means we might need an additional SP:

SP3) For 160M/80+80M, should having no 20M subchannels in the primary 80 MHz channel punctured (only in the secondary 80 MHz channel) be allowed?

Thanks,

Mark
