I see these in D3.0 at the specified locations (within rounding error):

When we discussed this in the
teleconf, I referred to CID 7796 in 16/0276, where we had got to:
·
A TS is a traffic stream
·
A TSPEC is a definition of a traffic stream
·
The UP is a number in the range 0-7 specifying a user priority
·
The TC is a number also in the range 0-7 but identifying a user priority or a frame that is not part of a defined traffic stream (not 100% sure how this differs from a UP, really
-- think group response (maybe from Mark?) was "UP notionally carried across MAC-MAC transport; UP can be mapped to TC either directly or via classifier; ditto on receive.
UP carried across SAP, TC is internal mechanism used to achieve this")
·
The TSID is a number in the range 8-15 identifying a defined traffic stream or a frame that is part of this stream (but the frames in this stream are, in EDCA, identified over the air by the UP for that stream)
·
The TID is a number in the range 0-15 that is a UP if it is <8 and is a TSID otherwise
·
BA is set up and identified on a per-UP (not per-TSID) basis
[think group response was "No, can be TSID (see e.g. 669.65).
In case of TS can have TCLAS. Use TC if no TSPEC in ADDBA
Req, use TS(ID) otherwise"] even for defined traffic streams (hm, so why 16 replay counters?
Or maybe you can have BAs under HCCA/HEMM/SPCA/SEMM?)
So at least then the direction was that you couldn't just delete TC
because it was involved in
TCLASes. I thought you were going to go
off and examine this point.
[Also, I don't understand the concept of a "frame UP" (CID 4145/4147) or
"MSDU or A-MPDU UP" (CID 4146) you are apparently trying to introduce.]
Thanks,
Mark

Hello All,
I’d like to start an e.mail discussion on doc 11-20/0814 which I presented on June 5.
From the teleconference minutes:
2.6.2.16 Two
instances of Traffic Categories are not included in the proposed changes that will need to be added.
2.6.2.16.1 ""Other
"traffic category" locations; P275.13 and P299.24
[osama] I have looked in drafts 3.0, 3.1, and 3.2 and couldn’t find these occurrences. Can someone point them to me, Note that my reference is draft 3.0
2.6.2.17 The
discussion was leading to removing TC and update the description on how UP is defined when it is not passed in through the MAC SAP
[osama] the description is already available P299, “The UP is provided with each MSDU at the medium access control service access
point (MAC SAP) either directly, in the UP parameter, or indirectly, in a TSPEC or SCS Descriptor element designated by the UP parameter”. Is there a need for something else? If yes, what is needed?
Please let me know if other things I need to consider.
Regards;
Osama.
