Re: [STDS-802-11-TGBE] TGbe Teleconferences [07/21/2021]: Agenda Posted-ERRATA CORRIGE



Hi, Tomo

Thank you for the comments.

 

I think both Wook Bong’s original resolution and my suggested resolution can be acceptable, then. I will just let go if Wook Bong wants to keep his resolution.

 

Regards

Junghoon

Hi Junghoon,

 

FYI, in REVme D0.1, there is the following:

9.3.1.19 VHT/HE NDP Announcement frame format(11ax)

The VHT/HE(11ax) NDP Announcement frame contains at least one STA Info field. If the VHT/HE(11ax) NDP Announcement frame contains only one STA Info field, then the RA field is set to the address of the STA that can provide feedback (see 10.36.5.2 (Rules for VHT sounding protocol sequences)). If the VHT/HE(11ax) NDP Announcement frame contains more than one STA Info field, then the RA field is set to the broadcast address.

 

So, when there are multiple STA Info fields, we can express the NDPA as a broadcast or groupcast frame.

On the other hand, for your proposal deleting broadcast makes sense, because the RA setting or whether the NDPA is a broadcast frame or an individually addressed frame do relates with the number of STA Info fields.

 

Best regards,

tomo

Hi, Wook Bong

Even the unicast NDPA frame can be detected by any STA, but we don’t call it a broadcast NDPA.

I think the broadcast is when the destinations are the unspecified multiple STAs. If we have specified the destinations (multiple destination STAs) in a frame, then, the frame is a multicast frame. I think the same group addressed RA may be used in the MAC header for both Multicast and Broadcast. I don’t know just my thought from the top of my head. Any MAC expert can comment on this?

 

Anyway, to avoid the controversies, what do you think about my suggested resolution? Just deleting the broadcast from the original text.

 

Regards

Junghoon

Hi Junghoon,

 

Thanks for feedback.

But it should be broadcast frame.

Anyone in the BSS will decode. Only one in the STA info will response.

What do you think?

 

Best regards,

Wook Bong Lee

Hello, Wook Bong

I have a comment on CR for CID 4150.

 

The NDPA with the multiple STA info fields is not a broadcast frame but is a multicast frame, because the destinations for the NDPA are only limited to those listed in the STA Info fields.

 

So, how about updating the CR for CID 4150 as follows ?

 

In a broadcast HE NDP Announcement frame that has more than one STA Info field with a value other than 2047 in the AID11 field, the following applies to each STA Info subfield with a value other than 2047:

— If the Feedback Type subfield indicates SU or MU, the Nc subfield indicates the number of columns, Nc, in the compressed beamforming feedback matrix and is set to Nc – 1

— If the Feedback Type subfield indicates CQI, the Nc subfield indicates the number of space-time streams, Nc, in the CQI report and is set to Nc – 1

In a broadcast HE NDP Announcement frame, the number of STA Info field with a value other than 2047 in the AID11 field shall be more than one.

 

In an individually addressed HE NDP Announcement frame with a single STA Info field, the STA Info field having a value in the AID11 field other than 2047, the Nc subfield is reserved. In an individually addressed HE NDP Announcement frame, the number of STA Info field shall be one, and the value of the STA Info field shall be other than 2047.

 

Your second resolution for the individually addressed HE NDPA looks good to me. No need to change.

 

Thank you

Regards

 

Junghoon Suh

Hi Eunsung,

 

Good catch! I further revise equation (36-22) in the updated version 1146r2 to incorporate phase rotations. Now it is in line with equations (36-21).

Hi Alice,

 

Thanks for the revision.

It looks better but I think phase rotation should be also employed since ER preamble can be larger than 20 MHz for now.

Hi Eunsung,

 

Thanks for your feedback. Previously I didn't catch that point and had thought CID 5005 was trying to revise the definition/use of D_{k,n,i_BW}. Equation (36-22) should have the same summation of i_BW as in equation (36-21), but it was missing in previous drafts. I have revised the resolution to CID 5005 accordingly in 1146r1.

 

Alfred, please note the updated version below.

Hi Alice,

 

I have a comment on your resolution for CID 5005. The comment of CID 5005 means that there is no definition of i_BW index in Equation (36-22) unlike the other equations. For example, in Equation (36-21), you can see the following term.

<image001.png>

 

If you want to keep i_BW in Equation (36-22), you need to add a similar term shown above. Phase rotation may be also needed.

Eunsung
