[STDS-802-11-TGBN] Follow-up discussion on 25/1950 P-EDCA CIDs

Hi P-EDCA TTT members,

 

Thank you for your comments on 25/1950r0 during today’s call. I would like to continue the discussion in this email thread and see the group’s preference on how to address the relevant CIDs.

 

In 11bn D1.2, we have the following text on conditions for a P-EDCA STA to start a P-EDCA contention:

A P-EDCA STA may start a P-EDCA contention if all of the following conditions are satisfied:

—           P-EDCA is enabled by the AP in the BSS and the P-EDCA non-AP STA has notified the AP of its intent to use P-EDCA on the link.

—           …

 

To make it more clear, one option would be updating the text as follows:

(Option 1) A P-EDCA STA affiliated with an MLD may start a P-EDCA contention on the link where the STA is operating in a BSS if all of the following conditions are satisfied:

—           P-EDCA has been enabled by the AP in the BSS.

—           The P-EDCA STA has enabled P-EDCA with the AP in the BSS on that link if the P-EDCA STA is a non-AP STA.

—           …

Some explanations:

  • The original first bullet is separated into two bullets, where the first one applies to all P-EDCA STAs (AP or non-AP STA), and the second bullet applies only when the P-EDCA STA is a non-AP STA.
  • In the second bullet,
    • “has notified the AP of its intent to use P-EDCA” is replaced by “has enabled P-EDCA” as we already have a clear definition of P-EDCA enablement.
    • The bullet starts with “P-EDCA STA” so that the subject is consistent with the main sentence, and the “non-AP” aspect is captured by adding “if the P-EDCA STA is a non-AP STA” at the end. (Personally I feel this way is better, but I’m also okay with using “P-EDCA non-AP STA” as before.)

 

We could also follow the original style by combining the first and second bullets together:

(Option 2) A P-EDCA STA affiliated with an MLD may start a P-EDCA contention on the link where the STA is operating in a BSS if all of the following conditions are satisfied:

—           P-EDCA has been enabled by the AP in the BSS and the P-EDCA non-AP STA has enabled P-EDCA with the AP in the BSS on that link.

—           …

 

Your feedback and suggestions are welcome.

 

 

Regards,

Zhenpeng
