OK, so these are:

> 11-20/0646 -- 24047, 24049, 24050, 24052, 24053, 24213, 24255, 24256, 24547
> 11-20/0540 -- 24522

As regards the latter, and as I have discussed with Youhan, I do not believe the

proposed change to the NOTE goes in the right direction.  The issue raised in

the comment is that the D6.0 NOTE says that the CH_BANDWIDTH is not the PPDU

width, but doesn't say which TXVECTOR parameter does indicate the PPDU width.

Instead, the resolution in CID 20/0540r2 replaces the NOTE:

NOTE—The TXVECTOR parameter CH_BANDWIDTH does not represent the channel width of the

transmitted PPDU.

with:

NOTE-The setting of the CH_BANDWIDTH parameter is determined by the triggering frame.
See 26.5.2.3.3 and 26.5.2.3.4.

However, to me this is going in the wrong direction, because (a) it does not
address the issue raised in the comment (about where the channel width of the
transmitted PPDU is represented), (b) it makes a statement that could
be made about lots of other parameters (many other TXVECTOR parameters for
HE TB PPDUs come from the triggering frame) and (c) it loses the caveat pointed
out by the NOTE in D6.0.

I understand that Youhan would like to have that sentence because he thinks that
information was not obvious to many readers in previous LBs.  I am fine with that
(clearly different people will have different opinions about what is obvious,
and so we should err on the side of verbosity), but to address (a) and (c) above,
the NOTE should then be:

NOTE-The setting of the CH_BANDWIDTH parameter is determined by the triggering frame
(see 26.5.2.3.3 and 26.5.2.3.4).  The CH_BANDWIDTH parameter does not represent the 
channel width of the PPDU.  The channel width of the PPDU is represented in the

RU_ALLOCATION parameter.

[The discussion in 20/0540r2 talks of "“bandwidth”" but neither the text in D6.0

nor the comment talk of "bandwidth", they talk of "channel width of the transmitted

PPDU".]

Thanks,

Mark

I’ve uploaded the agenda for the Teleconference. It is available at:

The agenda is on slide # 53. The CIDs ready for motions are on slide #54.

I deferred CID 24552 (11-20/317) and CIDs in docs 11-20/529, 11-20/0376, and 11-18/0218 since it seems more discussion is needed. Let me know if off-line discussions have helped come to agreement.
