I just had an interesting thought, probably late in the game: What if we define a TVHT PPDU transmission based on the existing VHT TXVECTOR and RX VECTOR parameter values? I am not certain of how one would identify it. E.g. We could leave everything untouched in most places, and then say that, for example, a PPDU transmitted with TXVECTOR CH_BANDWIDTH set to CBW40 when transmitted by
a TVHT STA in a TVWSB_W channel - (we would need to define that quantity) – then the PPDU being transmitted is a TVHT_W PPDU. We do not have to create new parameters – just give the parameters a different meaning when the TX is applied to a 6,7, or 8 MHz channel
or a 2W or 4W channel, etc. Of course – this is just a thought and we should probably just continue along the path, although after Jens gave up, I have been trying my hand at those 9.x subclauses
and am also finding things to be very difficult, but I am still trying to get it to work. Mostly, I am confused about which terms need to change and which do not. Matthew Fischer From: *** 802.11 TGaf - TV White Spaces OperationTask Group *** [mailto:STDS-802-11-TGAF@xxxxxxxx]
On Behalf Of Jens Tingleff Hi Matt, Only NON_HT_DUP_OFDM packets. Basically, we can do "inside" clause 23 what VHT can do "inside" clause 22 (i.e. transmit NON_HT_DUP_OFDM according to clause 22.3.10.12
and proper VHT) Best Regards Jens

[mailto:STDS-802-11-TGAF@xxxxxxxx] On Behalf Of Matthew Fischer What about a non-HT PPDU – VHT STA can transmit these things, but TVHT STA does not transmit them, right? Do we need a blanket statement somewhere at the top of clause 9 or something? Matthew Fischer From: Ron Porat
I think the latter. TVHT is a VHT. From: *** 802.11 TGaf - TV White Spaces OperationTask Group *** [mailto:STDS-802-11-TGAF@xxxxxxxx]
On Behalf Of Matthew Fischer Is there a TVHT PPDU? Do we need to change, in clause 9, occurrences of VHT PPDU to “VHT PPDU or TVHT PPDU”? Or do we assume that occurrence of VHT PPDU are sufficient to describe behavior for a TVHT STA, since a TVHT STA is a VHT STA? Matthew Fischer To report this email as spam click
