Thanks, Ruchen and Ross.

320-1 and 320-2 are distinguished by their center frequency. And Table E-4 is where we define channels, including their center frequency. Hence, I think Table E-4 is the appropriate place to distinguish 320-1 and 320-2. Please see CID 3175.

3175

230.20

36.3.11.7.2

The 320 MHz Operating class need to be separated to two - one for 320-1 and another for 320-2.

At P230L20, P236L24, P239L22, change "Set to 4 for 320 MHz-1. Set to 5 for 320 MHz-2" to

"Set to 4 for 320 MHz EHT PPDU occupying one of the channels defined in the Operating class 137 in Table E-4.
Set to 5 for 320 MHz EHT PPDU occupying one of the channels defined in the Operating class 138 in Table E-4."

In Table E-4 (P385L25), in the row of the Operating Class 137, under the column of "Channel center frequency index", change
"31, 63, 95, 127, 159, 191"
to
"31, 95, 159"

Add a new Operating class to Table E-4:
Operating class = 138
Channel starting frequency = 5.950
Channel spacing = 320
Channel center frequency index = 63, 127, 191

And update the Operating class numbers for the Reserved row appropriately.

Thanks.

Youhan

Hi Ruchen,

Thanks for the response. We can discuss during your presentation. If needed, we can describe it in the first place where it shows up, e.g., U-SIG subclause.

Hi, Ross

Thank you for the comment. I originally have the same thoughts, and that is how I compose Annex E for Draft 0.3. And I realize that the Operating class should not be abused, so yes, it may not be proper to split.

Then I feel that we shall find better place to define 320-1 and 320-2 other than Annex E, because we never define any BW (20/40/80/160 and 80+80) in Annex E. I think we can discuss during the PHY meeting to find a proper location for this definition.

Best,

Ruchen

Hi Ruchen,

Can you clarify why we need two different operating class in Annex E for 320-1 and 320-2?

I think the comment just wants to have some description of what is 320-1 and what is 320-2. You can add some description, which is similar as in SFD.

In addition to four entries for 20/40/80/160MHz, there exists two entries in U-SIG BW field for 320 MHz:

320-1 if PPDU channel center frequency is 31, 95, 159.
320-2 if PPDU channel center frequency is 63, 127, 191.

[Motion 135, #SP237, [48] and [80]]

Hi, Alfred, Sigurd and Tianyu

Please add the following document to the PHY queue.
