[STDS-802-11-TGBE] Comments on r7 // Re:[STDS-802-11-TGBE] PDT-MAC-MLO Enhanced Multi-link Single-radio Operation

Hi Minyoung,


Thanks for the preparation. I have the following comments on the PDT r7 of Enhanced Multi-link Single-radio Operation.

(1)

A single-link/radio (name is TBD) non-AP MLD is a non-AP MLD that supports operation on more than one link but receives or transmits frames only on one link at a time

Comment-1: This definition seems to be different from the concept of EMLSR mode, which allows to listen (i.e. receive) on more than one enable link (EMLSR links). Can the definition be clarified?

(2)

A non-AP MLD may operate in the enhanced multi-link single-radio (EMLSR) mode on a specified set of the enabled links.

Comment-2:Whether to add the AP MLD it associates as follows ?

A non-AP MLD may operate in the enhanced multi-link single-radio (EMLSR) mode on a specified set of its enabled links with the associated AP MLD.

(3)

The specified set of the enabled links in which the EMLSR mode is applied are called EMLSR links.

Comment-3: Whether not to exclude the scenario that there exist two sets of EMLSR links?  Whether to be modiefied as follows?

The specified set of the enabled links in which the EMLSR mode is applied are called EMLSR links for the same operation. A non-AP MLD that supports EMLSR mode may have one or more sets of EMLSR links.

(4)

An MLD with dot11EMLSROptionImplemented equal to true shall set the EMLSR mode subfield of the TBD Capabilities element, which is an MLD level capabilities element, to 1; otherwise, the MLD shall set the EMLSR mode subfield to 0.

Comment-4: Besides the MLD level capabilities element, the affiliated STAs corresponding to the links may have the capability of EMLSR mode for the link-level capability , which allows them to operate or not to operate on EMLSR mode.

(5)

Comment-5: The current draft text specifies the transceiving behaviour initiated by AP MLD. Should the transceiving behaviour initiated by non-AP MLD be specified?



Best Regards,

Liuming Lu

Hello TTT members for Enhanced Multi-link Single-radio Operation,

I've resolved all the comments and uploaded r6 for the draft text for enhanced multi-link single-radio operation:

Please review and let me know if you have any further comments. I'm planning to run a SP sometime next week.

Thanks,
Minyoung
