[STDS-802-11-TGBE] 答复: [STDS-802-11-TGBE] 答���: [STDS-802-11-TGBE] RDG/More PPDU subfield (CID 11827)

Hi Alfred,

 

OK, I see that sentence. I didn’t notice the different variant of HT control type when I prepared the text in 35.2.1.2, my mistake. The signaling could works for all variants of HT Control. We should remove the condition in 35.2.1.2.  What’s your opinion?

 

 

Regards,

Yunbo

Hi Yunbo, 

 

Thanks for the follow up. Not according to the TGbe draft. Please check 35.2.1.2.

 

Regards,

 

Alfred

Hi Alfred,

 

Thanks for sharing your opinions. The meaning of RDG/More PPDU only depends on the role of the STA. Once the STA is a target STA in MU-RTS TXS frame, the RDG/More PPDU subfield in HT/VHT/CAS Control field have the same meaning, which is return the allocated TXS time period to AP. A non-AP STA will be a TXS target STA and RDG responder at the same time.

Yunbo

I dont think the comment is saying that those variants are forbidden. The comment is saying that the RDG/More PPDU subfield is found in the HT variant, the VHT variant and the CAS Control field but only when carried in the CAS control field is it used for the purposes of MU RTS TXS triggering (ref some subclause in 35), When carried in the HT/VT variants it continues having the legacy meaning.

Hi Jinyoung,

 

Thanks for deferring this CID, and providing the explanation. But an EHT STA can support HT/VHT/HE/EHT PPDU, so no reason to disallow HT/VHT variant of HT control. So I don’t agree with the comment.

Yunbo

Hi, Yunbo and Abdel,

RDG/More PPDU subfield is in HT control for HT/VHT variant, and in CAS control among A-Control for HE variant as below.

The target STA in a MU-RTS TXS Trigger frame, that is newly defined, is an EHT STA. So RDG/More PPDU subfield for the target STA in a MU-RTS TXS Trigger frame is present in the CAS Control subfield as below resolution.

Comment

Proposed Change

Resolution

11827

9.2.4.6.1

122.04

This new interpretation is only valid when the RDG/More PPDU bit is included in the CAS Control. Add a note to the table specifying that the Target STA case is present when bit is in CAS control as defined in x.y.

As in comment.

Revised

 

Agree with the commenter and just add note below.

For your information, other explain about the subfield is described in REVme as below: ‘In a non-HE HT STA, the RDG/More PPDU subfield and the AC Constraint subfield are present in the HTC field. In an HE STA, the RDG/More PPDU subfield and the AC Constraint subfield are present in the CAS Control subfield.’

 

To TGbe Editor:

Please add the note below the Table 9-17.

‘NOTE: RDG/More PPDU subfield for the target STA in a MU-RTS TXS Trigger frame is present in the CAS Control subfield (See 9.2.4.6a.7 (CAS Control)).

If you have other opinion, please let me know.

Best regards,

Jinyoung
