Hi Alfred,

We reached a compromise with Ming on PDT MAC Coexistence.

I’d like to request the following straw poll during Wednesday AM1 before the motions:

Do you agree to incorporate the proposed text changes for coexistence found in 11-24/2040r8 into the 802.11bn draft amendment?

Thanks,

Laurent

Hi Alfred,

Please add the following motion into the list:

Move to include the following into 11bn SFD:

11bn defines the following modes for co-SR transmission:

Mode 1: trigger + same L-SIG contents, could be different U-SIG contents.

For UHR+EHT, or EHT+UHR or EHT+EHT co-SR transmission.
Provided no changes to non-UHR EHT non-AP STAs are needed.

Mode 2: Tigger + same L-SIG contents + same U-SIG contents

For UHR+UHR co-SR transmission.

For all modes, the two PPDUs will start and end at the same time.
UHR PPDU for co-SR transmission will be used for either mode 1 or mode 2 when UHR transmission exists.

There exists an indication in U-SIG field to indicate the UHR PPDU is a UHR PPDU for co-SR transmission.

Support document: 11/25-0104r0

SP result: 41Y, 7N, 20A (Sigurd please double check, thanks)

Hello, Alfred

The following SP has passed in the PHY session in PM2 of 14 Jan (Tuesday), and please, add it to the motion list.

SP1:

Do you support adding the following to the 11bn SFD?

In the UHR MU PPDU in 11bn, the PE requirements of UEQM with the constellation order x of the first spatial stream is equal to the PE requirements of EQM with the constellation order x?

Supporting document: [25/0128r0]

[No objection]

Thank you

Hello, Alfred

The following SP has passed in the PHY session in PM2 of 14 Jan (Tuesday), and please, add it to the motion list.

SP1:

Do you support including the following into the 11bn SFD?

11bn defines 5 bit Recommended CSI MCS subfield in the 2nd Special STA Info field of the NDPA targeted for OBSS AP in the UHR CoBF sounding

It is set from B20 to B24 in the 2^nd Special STA Info field
The 5-bit MCS level includes “No Recommendation” MCS entry in addition to the UHR MCS entries

Index 31 indicates “No Recommendation”

The Recommended CSI MCS is for the OBSS AP to set the MCS in the BFRP trigger frame sent in the future Cross-BSS sounding / Joint Sounding sequence
When there are multiple OBSS STAs to feedback the CSI report, the Recommended CSI MCS can be set to the lowest MCS among all those OBSS STAs

Thank you

Regards

Junghoon Suh
