Thanks for these contributions, Ming.
I have the following comments:
11-20-0979-00-00ax-mac-cr-on-BSS-Load-for-draft 6.0
- "the percentage of time, linearly scaled with 255 representing 100%"
-- if 100% is 255
then it's not a percentage. I suggest changing "percentage" to
"fraction" (3x)
[Ming]Agree, we should did the same change for BSS load and extended BSS load in REvmd
- "This percentage is computed" should
similarly be "The field value is computed" (3x)
[Ming]Agree, same as before
- The resolutions refer to document xxxx (3x)
[Ming] Fixed
11-20-0980-00-00ax-mac-cr-on-MU-Cascading-for-draft 6.0
- "and also may enable
the exchange of Control frames in both directions" is a bit weird,
because the Control frames might only go in one direction, right? Why
not delete "in both directions"? Or even this whole phrase?
[Ming] delete it
- "An MU cascading sequence shall not be exchanged between an AP and a non-AP STA (#CID 20732 and 20733)
unless"
is a bit weird. Maybe "shall not occur" or "shall not be used"?
[Ming]Adopt
11-20-0981-00-00ax-mac-cr-on-Fragmentation-for-draft 6.0
I don't think CID 24364 has really been addressed.
Let's look at Level 1, which should be the easiest:
— Level 1: support for one dynamic fragment that is a non-A-MPDU [in a PSDU (#24364)],
no support for dynamic fragments in an A-MPDU that is does not contain an S-MPDU.
So what does that mean?
It's clear I can only put my dynamic fragments in an S-MPDU, but beyond
that it's not clear.
Can I have multiple MSDUs fragmented at the same time (on different TIDs)?
[Ming] No if it is that A-MPDU
Can I have multiple MSDUs fragmented at the same time (to different STAs)?
[Ming] Maybe, one fragment in PSDU
If the receiver sees dynamic fragments for different MSDUs from the same STA,
does it need to assume that the earlier one was abandoned?
[Ming] abandon it in this case
Etc. Levels 2 and 3 are even more unclear.
It's possible that the intent is that all this "support for one" is intended
to be within the scope of a PSDU, i.e. just to prevent you, for level 1,
from having an A-MPDU with multiple dynamic fragments, but if so that's
not clear at all.
[Ming] your understanding is correct, do you have any suggestion if you think that is not clear
Also, it's not clear whether dynamic fragmentation is only for tx in an
HE TB PPDU. The original point was to make more efficient use of the
fixed HE TB PPDU durations, right? I can't immediately find such a restriction,
however.
[Ming] not only for TB PPDU, but also for HE MU PPDU, the initial stating point to reusing the wasted resource due to the ending time alignment in
OFDMA PPDU.
Thanks,
Mark
