Konnichiha Rison-san,
Thank you for sharing your thoughts.
I prefer your last proposal. How about adding the frequency range to exclude the *MG BSSes? Best regards, tomo From: Mark RISON <m.rison@xxxxxxxxxxx>
Konbanha Adachi-san, It would look like this: secondary 20 MHz channel: In a 40 MHz
basic service set (BSS), the 20 MHz channel adjacent to the primary 20 MHz channel that together form the 40 MHz channel of the 40 MHz BSS. In an 80 MHz BSS, the 20 MHz channel adjacent to the primary 20 MHz channel that together form the primary 40 MHz channel
of the 80 MHz BSS. In a 160 MHz or 80+80 MHz BSS, the 20 MHz channel adjacent to the primary 20 MHz channel that together form the primary 40 MHz channel of the 160 MHz or 80+80 MHz BSS. In a BSS, the secondary 20 MHz channel is also the secondary channel. Some other notes: - The definition probably also needs to be extended to support 320 MHz BSSes. - The "In a BSS," at the end is a bit weird now, and should probably be deleted. - I guess the "secondary {40, 80, 160} MHz channel" definitions should be similarly changed. Or we could make ourselves less vulnerable to spec rot (e.g. >320M BSSes in WIN) by just saying: secondary 20 MHz channel: In a 40 MHz
or wider basic service set (BSS), the 20 MHz channel adjacent to the primary 20 MHz channel that together form the (primary, for an 80 MHz or wider BSS) 40 MHz channel of the BSS. The secondary 20 MHz channel is also called the secondary channel. … but maybe then we need to exclude *MG BSSes! Thanks, Mark --

Hi Mark,
I’m not really sure how the definition will look
like when the proposed change is accepted, but it seems OK. The secondary 20 MHz channel should apply also when used in 2G4 for 40 MHz and in 6G for 40/80/160/320 MHz.
I’ll be at Bangkok.

I was asked to post to the reflector regarding CID 2630: Comment: "secondary 20 MHz channel" definition only seems to apply to a VHT BSS and hence does not apply to an HT or HE or EHT BSS in
the 2G4 or 6G band [Subclause 3.2 at 281.56] Proposed Change: Delete "VHT" and "very high throughput (VHT)" throughout the definition Proposed Resolution: ACCEPTED [Motion CID 2630] If you have any comments, this will come back up at the November F2F, or you could reply here. Thanks, Mark --
