Re: [STDS-802-11-TGBE] 答复: [STDS-802-11-TGBE] TGbe Conf Calls [May-July 2020]: Call For Submissions



Hi, Bin

Ross accepted to change the Ncol for RU132 to 21, so I do not want to dispute the parameter, but I’d like to mention one more time here in this email about the Ncol=Nsd/Dtm.

It was discussed in11ac, but it is not true in 11ax anymore. I took the example of RU26 case during the PHY call last Monday. For RU26, Dtm is supposed to be 3 according to the 11ac rule, but it is actually 1 in 11ax Spec.

 

I think “LDPC tone mapping becomes a special case of BCC interleaver” statement in 11ac is just a high-level rhetoric which does not have any technical meaning. LDPC tone mapping is constellation symbol-based and the BCC interleaver is the bit-level interleaver, and I do not think they have any technical relation.

 

Regards

Junghoon

Hi Ross

Thank your for deferring the SP on BCC interleaver for aggregated RU (20/773r1).  I do have a concern on the Ncol for RU132 (26+106).  Normally in spec,  Ncol=Nsd/Dtm so we prefer Ncol=126/6=21. There was some discussion back in 11ac time on this. In P33 2010/1300r0 LDPC for 11ac,  it mentions that when Ncol=Nsd/Dtm, LDPC tone mapping becomes a special case of BCC interleaver. Since the performance of Nco=21 and 18 are almost the same,  we want to keep Ncol=Nsd/Dtm for potential implementation benefit.

 

Thanks,

Bin

Hello all,

 

This is a call for submissions for the upcoming teleconference calls meeting. 

 

Please let me know if you have any items to be added to the agenda by sending me an e-mail with a request using the format below:

- DCN-Presentation Title (Author, Affiliation), Topic

 

Also please ensure that the presentation is uploaded at least one week prior to the conference call as I will include the links to the presentations in the Submission's list. If the contribution is not uploaded by that time then it may not be included in the list.

 

PS - There is no need to send an additional request for contributions that are already present in the conf call queue as they will be imported by default to the Back-Logged Submission's List.

 

Best Regards,

 

Alfred
