Re: [STDS-802-11-TGAX] 1528r0 - Segment parser changed to Subblock parser discussion

Hi Ross,

Given that 80MHz “segment” and “segment parser” is used for a long time and people understand the concept well, not sure we need to change the terminology now.

Since 160MHz has 1 segment, there is a de-parser for 160MHz. And frequency subblock is also not necessarily better than frequency segment IMO.

 

BRs,

Xiaogang.

主题: 1528r0 - Segment parser changed to Subblock parser discussion

 

Hi Brian and all,

 

There is one comment from Brian saying segment parser is not a good term for 160MHz PPDU because there is only one segment for 160MHz PPDU. Subblock parser is a better wording. Technically I agree with Brian. The only concern is that this is a procedure/term used since 11ac. Currently I make the changes as Brian suggested. All your comments are welcome.

Resolution

627.65

27.3.11.7.10

On behalf of Brian Hart:

 

From P566L27 in table 27-13, 160M has one frequency segment but 80+80 has two frequency segments, yet oftentimes 160M is treated as having two frequency segments when the correct term is frequency subblock (e.g. P627L65, P628L2, P630L13, P651L38). Also, confusingly, the segment parser for 160M has two outputs (and the deparser has two inputs)

Use "frequency subblock" where this is the more more correct language (check especially P627L65, P628L2, P630L13, P651L38). Add "number of frequency subblocks" to table 27-13; rename "Segment (de)parser to "Frequency subblock (de)parser" throughout the draft.

REVISED

 

Agreed with the commenter. Speify the changes below.

 

Instructions to the editor, plase make the changes as shown under CID 25009 in doc 11-20/1528r0

 

 

There are also 3 other comments that are also assigned to me. Your comments are also welcome.
