Hi all,

 

If possible, I would like to present in this week’s CC. I am also ok to choose a time that all interested parties can participate if there are further requests.

Hi Lili,

 

Yes, we can arrange it. I am not sure when Ross is presenting. Also Mark has asked to run a number of SPs. I prefer to schedule the discussion during a time when all interested individuals are available.

 

Regards;

Osama.

Hello Osama,

 

I have a submission, 618r0 (CID 24101), that is related to puncturing patterns and SP2. This is complementary to CID 24106 handled by Ross. It has also been briefly addressed last week while Ross presented his submission.   

It would be beneficial to review these CIDs in the same session. So I would like to ask if I can present my submission right after Ross’s one.

 

Thanks,

Lili.

Hi Mark and all,

 

I am to run SP1. For SP2, that is not part of my CID. Maybe Lili or somebody else later can request a SP.

 

Hi Osama,

 

It would be good if put the contribution 497r2 back in the queue to have some discussion first, before I run the motions according to the discussion.

Based on the subsequent discussions on the reflector, I think we need to

run the following two SPs to make progress:

 

SP1) For 160M/80+80M, should having all the 20M subchannels in the secondary 80M channel punctured be allowed?

 

SP2) For 160M/80+80M, should having more than two adjacent 20M subchannels punctured be allowed?

Note: for 160M this includes channels adjacent between the primary and secondary 80M channels, e.g. the ---xxx-- pattern

 

Thanks,

 

Mark

This is the follow-up to the teleconf discussion just now, to

attempt to reach consensus on which puncturing patterns are and

are not allowed.

 

STRAWMAN PROPOSAL:

 

If the primary 20 MHz channel is the leftmost one, and x means

punctured, - means not punctured and ? means can be punctured,

then these correspond to only allowing the following patterns

in each case (obviously the patterns will get rearranged if the

P20 is not the leftmost one) for the value of the Bandwidth

field in the HE-SIG-A field of an HE MU PPDU:

 

4) -x--

5) --x- or ---x

6) -x--???? but not -x--xxxx

7) --x-???? but not --x-xxxx, or

   ---x???? but not ---xxxxx, or

   --xx???? but not --xxxxxx

 

During the teleconf I think I heard some variants proposed (calling

the one above z):

 

a) Allow full puncturing of S80, i.e.:

 

4) -x--

5) --x- or ---x

6) -x--???? including -x--xxxx

7) --x-???? including --x-xxxx, or

   ---x???? including ---xxxxx, or

   --xx???? including --xxxxxx

 

b) Don't allow any puncturing of S80 (maybe the D1.0 wording?), i.e.:

 

4) -x--

5) --x- or ---x

6) -x------

7) --x----- or

   ---x---- or

   --xx----

 

c) Allow "any 2" puncturing for the 7 case (I think I heard something

like that?), i.e.:

 

4) -x--

5) --x- or ---x

6) -x--???? [all x for ? TBD]

7) --x-???? where exactly one of the ?s is a x, or

   ---x???? where exactly one of the ?s is a x, or

   ----???? where exactly two of the ?s are an x, or

   --xx----

 

d) Or was it "at least 2" puncturing for the 7 case, i.e.:

 

4) -x--

5) --x- or ---x

6) -x--???? [all x for ? TBD]

7) --x-???? where between 1 and 3 (4 TBD) of the ?s are xs, or

   ---x???? where between 1 and 3 (4 TBD) of the ?s are xs, or

   ----???? where between 2 and 3 (4 TBD) of the ?s are xs, or

   --xx???? where between 0 and 3 (4 TBD) of the ?s are xs

 

Plus a variant to any of the above:

 

e) For any/all of the above, don't allow more than 2 adjacent xs

for the 160M case (obviously N/A for 80 and I think also for 80+80)

 

Please select your option (z or a-d, plus e) or otherwise describe

your understanding.

 

Happy Easter, and best wishes to you, your colleagues and your families,

 

Mark
