Hi Mark-san,
Thank you for re-starting this discussion.
Adding restriction to only allow modification to the timeout will be a new rule.
By the text changes that you proposed below, it does not step in how the parameters other than the timeout value should be.
So, it looks as though the originator can set any values to those parameters and the recipient is required to figure out whether there is an existing agreement, and if there is, then to adopt
only the timeout value, which will be an additional new behavior.
BTW, is modification to timeout value really useful?
In the 11e days, there was only full state BA and it might have been useful to adjust the time to free up memory after starting the operation.
But now by partial state being introduced, does it still really matter?

Sorry to repeat, but my understanding is, when the modification is accepted, the parameters are re-initialized/overwritten.
Best regards,
tomo

Subject: [STDS-802-11-TGM] 11me/D4.0 CID 6171 -- BA modification
--- This message came from the IEEE 802.11 Task Group M Technical Reflector ---
When we discussed CID 4341, it became clear that it was not clear how
modification of any of the parameters of a BA agreement except the
inactivity timeout would behave.
On this basis, CID 6171 is proposing to restrict BA agreement modification
to modification of the timeout, since it is straightforward to specify how
this works. The specific changes proposed are:
In 10.25.2 and 11.5.1 change
"All parameters of [the/an] agreement may be modified except for the TID." to
"Only the block ack agreement timeout may be modified."
In 11.5.4 change
"The inactivity timer at the recipient
is also reset when a BlockAckReq frame with the TID for the block ack agreement is received. The inactivity
timer at the originator is reset when a BlockAck frame with the TID for the block ack agreement is received." to
"The inactivity timer at the recipient
is also reset when a BlockAckReq or ADDBA Request frame with the TID for the block ack agreement is received. The inactivity
timer at the originator is reset when a BlockAck or ADDBA Response frame with the TID for the block ack agreement is received."
If you have any thoughts on this proposal, do respond. If you think
any BA agreement parameter other than the timeout should be modifiable,
please indicate how such modification would operate.
Thanks,
Mark
