Hi CoBF/CoSR PoCs and TTTs,
Thanks for the feedback you all provided on 26/302. I wanted to initiate this thread to summarize the feedback and explore possible ways forward.
In this CR document, we proposed a signaling scheme to help eMLSR/DPS STAs switch back to listen/LC mode earlier at the end of CoBF/CoSR TXOPs. The main idea was to achieve this using a baseline scheme/frame
with minimal changes to the current spec.
The proposed scheme can be summarized in 3 points:
- The coordinating AP shall transmit a CF-End frame to end the CoBF sequence.
- The coordinated AP may transmit a CF-End frame following that of the coordinating AP.
- The non-AP STA may switch back immediately once receiving any of the CF-End frames.
The majority of feedback I received can be summarized under two directions:
- Some members recommended stronger language on the coordinated AP
à Use a “shall” condition.
- Some members recommended softer language on the coordinating AP
à Use a “should” condition.
As it is clear, the recommendations are conflicting, hence I suggest that we find a middle ground where it is mandated with a “shall” on the coordinating AP while keeping the flexibility on the coordinated
AP with a “may”.
Please let me know your thoughts.
Regards,
Sherief
