Hi Ross,
Thanks for the response.
Yes, we can use preamble puncturing for TB PPDU but I agree that using a consistent term may be better.
Let’s further hear other members opinion.
Best regards,
Eunsung

Hi Eunsung,
Thanks for initiating the discussion. Overall changing preamble puncturing to unallocated would make the description for all DBWs more consistent and easier.
Preamble puncturing indeed could happen with TB PPDU, in 802.11be 36.3.20.1.2, we have:
The puncturing pattern in an EHT MU PPDU is indicated by the punctured channel information in U-SIG field. The puncturing pattern in an EHT TB PPDU and non-HT duplicate PPDU is determined by TXVECTOR parameter INACTIVE_SUBCHANNELS.

Hi All,
I suggest two options to resolve the CID below.
- Option 1: change “preamble puncturing” to “unallocated”
- Option 2: Reject the CID based on the current motion.
I’d like to hear which option you would prefer. Also, I am open to other options and please let me know if you have any.
Best regards,
Eunsung

Hi All,
I am sending this email to discuss the following CID.
2689 | Youhan Kim | No | 38.3.4 | 110 | 14 | T | 38.3.4 | 110.14 | I don't think we use the term 'preamble puncturing' for TB PPDU. | Don't have a specific suggestion, but please check whether the term 'preamble puncturing' is appropriate for TB PPDUs. | PHY |
The following is the spec text that Youhan mentions.
Basically, I agree that preamble puncturing is not generally used for TB PPDU but in the motions for DBW modes, we used this term. At first, to resolve this CID, I suggested to use “unallocated” which is used in 11be but finally decided to defer it. I’d like to members’ opinion on this CID. Any suggestions are welcome.
Best regards,
Eunsung
