Hi Sigurd,Tianyu,Alfred,

Could you please add the following item to the PHY agenda.

Hi Rethna,

 

Good catch!

I just copied it from 11ax draft mindlessly.

 

Additional modification is under way such as unified symbol form of NDBPS,u for SU/MU transmission.

When ready, I will share one more time.

 

Regards,

Yujin

Hi Yujin,

 

A short note: The mapping should be Ndbps=floor(Ncbps*R), where R the coding rate. In your Eq, it shows as a division by R.

 

Regards,

Rethna.

Hi Ron,

 

Please find the updates.

  • BPSK-DCM as TBD MCS index updated in all tables
  • BPSK-DCM-DUP as TBD MCS index updated in 996-tone RU, 2x996-tone RU and 4x996-tone RU

 

Regards,

Yujin

Hi Yujin,

 

Understood now, thanks.  We can keep your table (opt 1).

 

One suggestion I have is to get rid of the DCM column and separate the BPSK square into two separate BPSK and BPSK+DCM. 

 

I also think that your table should include on top a new entry for BPSK+DCM+DUP (only for the cases agreed on) because this is a new lowest rate.

 

 

Thanks,

Ron

Hi Ron

 

I am sorry that I didn’t make it clear enough.

Please find the attached to share what Wook bong, Edward and me briefly discussed yesterday.

 

Looking at DCN0997 tgbe-spec-text-volunteers-and-status..docx, there are two subjects below.

What I thought, when those were assigned, is EHT Modulation and coding schemes correspond to 27.3.7 (HE modulation and coding schemes (HE-MCSs)) while Parameters for EHT-MCSs correspond to 27.5 (Parameters for HE-MCSs). So DCN 1290 includes a bunch of tables for Parameters for EHT-MCSs.

 

Rethna’s draft includes two subjects together in DCN1338 so now we have contents conflicts.

We might have three options…

  • Opt.1 Remove the table in DCN1338 and refer the tables in DCN1290
  • Opt.2 Contents in DCN1290 could be combined into DCN1338.
  • Opt.3 keep your format and update it based on the feedbacks then I withdraw DCN 1290.

 

There was discussion on whether to include whole tables…. (more than 100 pages full of tables to cover variable RU sizes with up to Nss 16)

For the first version as reviewed in TTT discussion, we decided to make it simple.

As a result, it just presents one table with Nss 1 for each RU and for the rest (Nss 2 to 16) to be calculated by multiplying Nss.

 

Any options are fine to me.

 

Regards,

Yujin

Hi Yujin,

 

Thank you for your review.  Could you explain your comment [yn3]? I’m not following what you propose to do.

 

Thanks,

Ron

Dear PHY EHT Modulation and Coding Schemes (EHT-MCSs) TTT members,

 

 

Please review and share your comments. Unfortunately, the document has a decent number of tables to cope with. If you wish, feel free to revise. 

 

Regards,

Rethna.
