| Hi Alice,
Thank you for preparing the draft. I have a question on Table 9-46a last two rows. The last two rows are designed for UL APPDU in 11be. They are not used by EHT AP, but EHT non-AP STA needs to be able to interpret those two rows. Based on the current 11bn development, I don’t see APPDU will be adopted in 11bn or future generations. I am not sure why UHR still needs to carry these two rows to add burden on the non-AP UHR STA side. DSO operation definition already eliminated the use cases of triggering mixed generations non-AP STAs in one PPDU. I think there is no reason to add UHR variant in row 4 in the table. Note 2 mentioned that those two rows are not used by and EHT or UHR AP, then why we need non-AP EHT or UHR STAs to be able to respond to it. What will be the use cases?
Table 9-46a—Valid combinations of B54 and B55 in the Common Info field, B39 in the User Info field, and solicited TB PPDU format Common Info field B54 | Common Info field B55 | User Info field B39 | Presence of Special User Info field | User Info field variant | TB PPDU type | 1 | 1 | 0 | No | HE variant | HE | 0 | 0 | 0 | Yes | EHT/UHR variant | EHT/UHR | 0 | 0 | 1 | Yes | EHT/UHR variant | EHT/UHR | 1 | 0 | 1 | Yes | EHT/UHR variant | EHT/UHR | 1 | 0 | 0 | Yes | HE variant | HE |
NOTE 2—Although the last two rows in Table 9-46a (Valid combinations of B54 and B55 in the Common Info field, B39 in the User Info field, and solicited TB PPDU format) are not used by an EHT AP (see 35.5.2.1 (General)) or a UHR AP (see 37.TBD (General)), a non-AP EHT or UHR STAmight respond to a Trigger frame with B54 in the Common Info field equal to 1 and with B55 in the Common Info field equal to 0 based on the two rows.

Dear Fellow Trigger Frame TTT,
Attached please find an updated draft PDT to address earlier comments. Please review.
Regards, Dear Fellow Trigger Frame TTT, Xiaogang, Ross, Thank you for your comments. I combined all comments from Xiaogang and Ross into the attached draft v0 with my replies. Other private offline comments have been replied to. In a next email, I plan to circulate a revised draft v1 to address all comments. In v1, due to deletion and revision of certain portions of draft, some comments and replies would be entirely deleted. So, I would like to keep a separate v0 in this email for your reference. Regards, Alice Chen Qualcomm WARNING: This email originated from outside of Qualcomm. Please be wary of any links or attachments, and do not enable macros. Hi Alice, Thanks for preparing the PDT, attached please find my comments. In general, there is also some description on trigger frame in 11-24/2046r2. I suggest 11-24/2046r2 to align with this PDT (or simply delete the trigger frame part), as this is more comprehensive. regards 于健 Ross Jian Yu Huawei Technologies 发件人: Alice Jialing Li Chen <jialing.li.phd2@xxxxxxxxx>
