I have a couple of related comments:
|
25055 |
Puncturing has broken the definition of "frequency segment: A contiguous
block of spectrum used by a transmission." |
Change the definition to end "or a block of spectrum used by a transmission
that would be contiguous were it not punctured" |
|
25056 |
"20 MHz frequency segment" is a misnomer: these are not frequency segments,
these are subchannels |
Change "20 MHz frequency segment" to "20 MHz
subchannel" throughout (11 instances) |
I agree we should not change the definition of "segment" now (hence my CID 25056
to fix the references to "20 MHz frequency segment") but we do need to account
for puncturing within a segment (hence my CID 25055 to allow this).
Thanks,
Mark

1528r0 - Segment parser changed to Subblock parser discussion
Hi Xiaogang,
Thanks for the comment. Segment parser within a segment is also acceptable to me. And the inline text already mentioned the bits are divided into two frequency subblokcs.
Let’s see if others have further comments.

RE: 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.

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.

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.
Below please find the link to the document.
