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 From: Bin Tian [mailto:btian@xxxxxxxxxxxxxxxx]
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 From: Yujian (Ross Yu) <ross.yujian@xxxxxxxxxx>
