The Operating Class and Primary Channel subfields are present if the FILS Discovery frame is transmitted in a non-HT duplicate PPDU.
Does this need an "and are not present otherwise"?
When present, the fields
indicate the following:
·
If the operating class has a channel spacing other than 80 MHz
·
Operating bandwidth of the BSS (which equals to the channel spacing of the operating class)
I think the term is "BSS bandwidth".
Also, I think the parenthetical is confusing and this would be clearer as "BSS bandwidth, equal to the channel spacing"
·
Center frequency of the BSS
I am not sure a BSS has a frequency per se.
Maybe by analogy with T9-313 etc. say "Center frequency of the channel on which the BSS operates"?
·
The center frequency of the primary channel
"The center" -> "Center"
·
If the operating class has a channel spacing of 80 MHz
·
Operating bandwidth of the BSS is either 80 MHz or 80+80 MHz
BSS bandwidth
·
Center frequency of the primary 80 MHz channel
Is there a primary 80 MHz channel in an 80 MHz BSS?
See definition: "primary 80 MHz channel:
In a 160 MHz or 80+80 MHz basic service set (BSS), the 80 MHz channel that is used to transmit 80 MHz physical layer (PHY) protocol data units (PPDUs)."
·
The center frequency of the primary channel
"The center" -> "Center"
NOTE 1 – If a received FILS Discovery frame does not include the Primary Channel subfield, the primary channel is the channel on which the PPDU was received.
NOTE 2 – A STA that receives a FILS Discovery frame containing an Operating Class subfield indicating a channel spacing of 80 MHz can determine the operating bandwidth of the BSS
by receiving a Beacon or a Probe Response frame on the primary channel indicated in the FILS Discovery frame.
BSS bandwidth
Thanks,

Hi All,
During last week's TGm call, we discussed the resolution for CID 1011 and made a few live updates to the proposed text. Shown below is the text that we ended up with during the call. I’d
like to check if there are any further opinion/suggestions related to this text.

The
Operating Class and Primary Channel subfields are present if the FILS Discovery frame is transmitted in a non-HT duplicate PPDU. When present, the fields
indicate the following:
·
If the operating class has a channel spacing other than 80 MHz
·
Operating bandwidth of the BSS (which equals to the channel spacing of the operating class)
·
Center frequency of the BSS
·
The center frequency of the primary channel
·
If the operating class has a channel spacing of 80 MHz
·
Operating bandwidth of the BSS is either 80 MHz or 80+80 MHz
·
Center frequency of the primary 80 MHz channel
·
The center frequency of the primary channel
NOTE 1 – If a received FILS Discovery frame does not include the Primary Channel subfield, the primary channel is the channel on which the PPDU was received.
NOTE 2 – A STA that receives a FILS Discovery frame containing an Operating Class subfield indicating a channel spacing of 80 MHz can determine the operating bandwidth of the BSS
by receiving a Beacon or a Probe Response frame on the primary channel indicated in the FILS Discovery frame.

Is there a strong opinion against removing the 2nd sub-bullet (related to ‘Center frequency’)?

Abhi
