Hi Minyoung,
Thanks for your immediate response. I have some further response below.

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?
[Response1] The definition in subclause 3.2 (Denitions specific to IEEE 802.11) is for a single-link/radio non-AP MLD, and not related to the EMLSR mode.
[Further Response1] whether is it needed to add the definition of EMLSR to subclause 3.2 ?
(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.
[Response2] I'll change the sentence in r8 as follows: "... the enabled links between the non-AP MLD and its associated AP MLD."
[Further Response2] OK.
(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.
[Response3] I don't see a good reason to have more than one set of links for this mode of operation.
[Further Response3] I think EMLSR mode would be more flexible , and doesn't depend on the implementation. Maybe it needs further study.
(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.
[Response4] There could be such capabilities but the task group haven't had any technical discussions on the details and consensus so for D0.1 draft text we would just have this level of details.
[Further Response4] it also concerns the flexibility of EMLSR mode, and needs further study.
(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?
[Further Response4] How does non-AP MLD select the link to transmit data if it has data to transmit and listens on EMLSR links?

Liuming Lu
