Hi, Yujin.
Thank you for
https://mentor.ieee.org/802.11/dcn/21/11-21-0157-02-00be-pdt-effect-of-ch-bandwidth-parameter-on-ppdu-format.docx.
While I understand the document has passed SP last week, I find the portions related to non-HT duplicate transmission difficult to understand.
For example, Table 36-x2 is purely about transmitting non-HT duplicate PPDUs, but it talks about “non-OFDMA” and “OFDMA” cases. But non-HT duplicate PPDUs have no concept of non-OFDMA and OFDMA.
I suggest to
- Delete Table 36-x2 and relevant texts
- Put non-HT duplicate related information in Table 36-x1
Attached document is one such implementation.
Thanks.
Youhan

Hi Lei,
Thank you for your comment.
In the uploaded version on the server, it’s been fixed as below.
I hope it could be able to reflect your intention (nonpunctured or punctured) as well.
Regards,
Yujin

Hi Alice and all,
Please find the updated version.
- Added B3-B6 of U-SIG2 to make it clear for the OFDMA case.
- remove nonpuctured cases for CBW80/160/320 from the table.
If you have comments or concerns, please let me know.
Regards,
Yujin

Hi Alice,
That’s a good point.
I will update it based on your two comments.

Hi Yujin,
Two comments to Table 36-x2 in the PDT:
1. For the OFDMA case, do you need to refer to the 4-bit bitmap (B3-B6 of U-SIG-1) to be more specific?
2. Is there a need to split each CBW into the nonpunctured case and punctured case? Note that the non-OFDMA case includes the nonpunctured pattern. In the next spec draft which will incorporate resolved CIDs in the U-SIG subclause, the
pattern '1111' would be added to the OFDMA case as well. So, the nonpunctured case is just a special case to the general _expression_ of the punctured pattern.
Best regards,
Alice Chen

Hi all,
Attached please find the PDT for Effect of CH_BANDWIDTH parameter on PPDU format.
Based on the discussion last teleconference call, all the puncturing patterns for both non-OFDMA and OFDMA are included in INACTIVE_SUBCHANNELS parameter.
With this PDT to be approved, then one CID linked to this document would be ready.
Let me know if you have any comments and questions.
Regards,
Yujin
