Thanks Arik for preparing the doc. More comments from me follows…

 

7799/7800/7801/7802:

  • Why are we calling out the description of the fields twice; once for the MAPC Discovery Req/Resp and another for MAPC Negotiation Req/Resp?

[AK] The problems with the current text (as reflected in these CIDs) are as follows: (1) The term in “The AP can store for this Co-BF pair…” is incorrect in case that the MAPC element is carried in the MAPC Discovery Request/ Response frames. There is no “pair AP for Co-BF” since at this stage no Co-BF MAPC agreement is being established. (2) The term in “The AP can store for this Co-BF pair…” is not clear to which pair you refer in case that the MAPC element is carried in the MAPC Negotiation Request/ Response frames.

My proposed solution (in 410r2) for these issues is: (1) in case of MAPC Discovery Request/ Response frames the sentence is revised to “the AP can receive and store for OBSS non-AP STAs associated with a further non-colocated AP for which the Co-BF Supported field is equal to 1 “
(2) In case of MAPC Negotiation Request/ Response frames, the sentence is revised to “the AP can receive and store for OBSS non-AP STAs associated with the recipient AP of the frame “

[SH] Ok makes sense. You want to split because for discovery and negotiation the recipient of the frame is different. To have more concise text, can you rephrase to make it one description and in the same description mention that this MAPC Profile can be included in a MAPC Discovery or MPAC Negotiation frame? I think that will capture your idea without duplicating the field description because the field description is the same.

[AK] First, there is a difference in the description between MAPC discovery and MAPC negotiation: in the MAPC discovery case the max value refers to any AP that supports Co-BF and in case of the MAPC negotiation the Max value corresponds to the recipient AP of the transmitted frame (i.e. the AP with which the AP request or response to perform the MAPC operation).
Second, I do not really understand your request above to include everything in one (complex) sentence. Do you have any suggested text?

  • Also why did you redefine the encoding of the fields? That is not needed and will require defining the maximum that you are subtracting from.

[AK] The original sentence includes 2 different issues: description for the indication of this field and the encoding of this field. The CIDs 7799, 7801 proposed (for better readability) to split the sentence into 2 separate sentences.
Besides, the revised sentence “ The encoding of the field (i.e. the Number of Supported Sounding Reports field ) is set to the maximum number of supported OBSS Sounding reports minus 1“ is equivalent to “ The maximum number of OBSS Sounding Reports  is equal to the value of the
Number of Supported Sounding Reports field plus 1 “ so no redefinition is required here.

[SH] Since they are equivalent can we stick to the original field encoding?

[AK] There is not difference in the encoding since the encoding (i.e. the value that is kept in the Number of Supported Sounding Reports field) is always reduced by 1 from the value of the maximum number of OBSS Sounding Reports. For instance: if the maximum number of OBSS Sounding Reports=4, the value kept in the Number of Supported Sounding Reports field is 3.
The only difference between the sentences is the subject of the sentence whether it is the field (i.e. Number of Supported Sounding Reports field ) or the value it represents (i.e. maximum number of OBSS Sounding Reports). My preference is to use the sentence where the field is the subject of the sentence.

 

7803/67804:

  • Can you please clarify the intention of that change? I am not clear on the changes proposed.

[AK] The modification clarifies the exact case where the MAPC Scheme Request field is included in the Co-BF/Co-SR profile – when the MAPC element is carried in MAPC Negotiation Request/ Response frames (as requested by the commenter).

[SH] Let’s check this one with Giovanni

Sherief

Thanks for the document Arik.

 

Some comments here:

 

7798: keep the definitions e.g. ‘Co-RTWT profile’ in 3.2 as well (add missing ones in 3.2).

 

10474: I the sentence is removed, where is it clarified that only one profile per scheme can be added?

 

7791: not convinced that this is a wording improvement, I would refrain from changing in this way.

 

Best,

Giovanni

Hi all / MAPC TTTs

 

I’ve uploaded 11-26/0410r0 (29 CIDs) on the mentor.

Your review and comments are highly appreciated.

Arik
