Re: [STDS-802-11-TGBN] [EXTERNAL] [STDS-802-11-TGBN] PDT-MAC-NPCA


John,

If you retain the term NPCA, and then use the term Alternate Primary Channel, then you lose a nominal coupling to the NPCA mechanism.

If we change the name of NPCA to TACA = Temporary Alternate Channel Access, and then call the new primary as the Alternate Primary Channel, then there is a nice nominal pairing between the name of the feature/mechanism/operational mode and one of the items that is a subject of that mode.

e.g. If we use TACA, then when a STA switches to TACA operation, the STA is performing Temporary Alternate Channel Access on an Alternate Channel where there is an Alternate Primary Channel.

You could even drop the T and just have ACA
Alternate Channel Access
Alternate Channel
Alternate Primary Channel

Some might argue for changing "Channel" to "Subchannel", as the Alternate Channel is supposed to be a portion (i.e. subchannel) of the normal BSS Operating Channel

Bur dropping Temporary loses the ephemeral nature of the channel, hence my inclusion of "temporary", so, I think it is better to drop the Alternate label, as Temporary sort of covers the alternate nature of it anyway:

Temporary Subchannel Access = TSA
Temporary Subchannel
Temporary Primary Channel

Or, you could use Interim:

Interim Subchannel Access
Interim Subchannel
Interim Primary Channel

more choices:

Transient
Ephemeral
Fugacious
Capricious

Matt,

  One note – when I proposed the phrase “Alternate Primary Channel Access”, I was not proposing that we use “APCA primary channel”, but that we use “Alternate Primary Channel” to refer to the channel used for access control.

After receiving some editorial comments regarding 1762r2, I have made many of the suggested editorial changes and then added some of my own.

The result is a new r3 version that is now available on the server:

Thanks to those who submitted comments on 1762r1.

Due to the large volume of motions that were passed regarding the NPCA feature, there is a new revision of 1762 that has been uploaded.

This revision is constructed from several comments/proposed text sections that I received from various TTT members and then consolidated into the r2 version of 1762.

The changes are vast.

This latest revision can be found on the server:

 

 

Note that because of the amount of changes made to the earlier revision of the document, those comments that were sent to this email thread were not directly addressed.

 

As to the comment from John Wullert regarding terminology, I agree that the term NPCA primary channel seems a bit clumsy upon expansion of the acronym.

John's suggestion is an interesting alternative, but I would not unilaterally adopt it without first soliciting additional opinion on the matter.

[of course, at this point, no one else has responded... so maybe there is no other opinion!]

[and I'll note that if you do not expand the acronym, the term isn't so clumsy]

[and I'll note that even with John's proposal, upon expansion, you still get a "double primary" problem - e.g. APCA Primary Channel = Alternate Primary Channel Access Primary Channel]

 

How about TACA - Temporary Alternate Channel Access

 

No change has yet been made to that term.

Matt,

   Thanks for this.  The one comment I have is related to terminology – It seems to me that “non-primary channel access primary channel”, the expansion of “NPCA primary channel”, has the potential to lead to confusion.  It might be better to call this feature “Alternate Primary Channel Access”?  In that case, what is currently labeled “NPCA primary channel” would become the “alternate primary channel”, which seems much more descriptive and clearer to me.  (Given that the motions use NPCA, it may be that this is the wrong place to have the discussion…)
