[STDS-802-11-TGAX] 11ax comments



Hi Ming,

 

Based on the telecon discussion today, I assigned you the comments below. 2 on fragmentation and 2 on cascading.

 

Are you able to provide resolutions for review at the November session?

26.3.2.2

The 2 bullets miss a condition when the recipient indicates that it is capable of level 2 or 3, and in the BA agreement explicitly/implictly neogotiated level 2 or 3. Under the Note in P318.37, the originator is allowed to send level 1 dynamic fragements in this case.

add the missing condition

The baseline says "A fragment is an MPDU, the Frame Body field of which carries (#1452)only a portion of an MSDU orMMPDU." However, in HE a fragment can carry a portion of an A-MSDU, which might be more than a portion of an MSDU

As it says in the comment

26.5.3

CID 20732. The resolution is vague and not responsive to the comment "Re CID 16076: the comment was valid. The normative requirement is that cascading is defined by the use of "an A-MPDU to a non-AP STA that includes an Ack or BlockAck frame together with a Trigger frame or a frame carrying a TRS Control subfield." (342.33)"

Change the first sentence of the referenced subclause to "An MU cascading sequence is a frame exchange sequence between an AP and a non-AP STA where at least one transmission by the AP is a triggering PPDU that includes an acknowledgment."

CID 20733. The resolution is vague and not responsive to the comment "Re CID 16076: the comment was valid. The normative requirement is that cascading is defined by the use of "an A-MPDU to a non-AP STA that includes an Ack or BlockAck frame together with a Trigger frame or a frame carrying a TRS Control subfield" (342.33). The resolution suggests this is wrong"

Change the first sentence of the referenced subclause to "An MU cascading sequence is a frame exchange sequence between an AP and a non-AP STA where a triggering PPDU follows after SIFS an UL MU transmission." Elsewhere, change "An AP shall not transmit an A-MPDU to a non-AP STA that includes an Ack or BlockAck frame together with a Trigger frame or a frame carrying a TRS Control subfield unless" to "An AP shall not transmit a triggering PPDU a SIFS after an HE TB PPDU the AP has triggered unless"
