Hi Dmitry,
Thank you for the updated proposal. I would like to clarify why I believe CID 14072 remains valid and should be reconsidered.
Before initiating P-EDCA contention, a STA should assess whether sufficient time remains to complete the P-EDCA contention procedure and at least one data exchange, including any required control and response frames. If insufficient time remains, the STA should refrain from initiating P-EDCA contention. An explicit initiation condition would help avoid such unnecessary attempts and their associated overhead.
The earlier rTWT discussion cited in the proposed resolution concerns restrictions governed by the rTWT mechanism. My comment addresses the broader question of whether sufficient time remains, regardless of the particular reason limiting that time. We therefore do not need to enumerate individual causes or modify the existing rTWT rules.
A similar principle already exists for NPCA. Section 37.18.3 requires the remaining PPDU/TXOP duration, after subtracting switching and switch-back delays, to exceed the NPCA Minimum Duration Threshold as a condition for switching to the NPCA primary channel.
This provides a precedent for checking the usable time before initiating a specific channel access procedure (i.e., NPCA and P-EDCA).
I therefore believe that the proposed resolution of CID 14072 should be reconsidered. Thank you.
Best regards,
Pei Zhou
