Hi George, The “P matrix” here refers to the space-time mapping matrix for LTFs, as defined for (V)HTLTFs in 11n/ac. The correct citation should be equation (22-44) in clause 22.3.8.3.5 VHT-LTF definition of Rev-mc D4.0. Thanks Hongyuan From: *** 802.11 TGax - HEW - High Efficiency WLAN *** [mailto:STDS-802-11-TGAX@xxxxxxxx] On Behalf Of George VLANTIS Hi Robert, I wasn’t in Berlin, but I see some meat got put on the bones. There is a “P Matrix” at the top of page 3 in the spec framework doc r4, that I believe is referring to the BCC interleaver in 802.11ac (which of course doesn’t apply to LDPC data). It might improve readability, clarity and accuracy to cite Clause 22.3.10.8 “BCC Interleaver” in IEEE Std 802.11ac™-2013, until such time as 802.11mc is stable, if that is what is meant. Cheers.
