Shubho,

thanks for the feedback. I think the term "switching" is justified, as the non-AP MLD listens on multiple receive chains and then "switches" its operation to exchange frames on one link. I think the term "perform" implies that the non-AP MLD may still be listening on the other receive chains.

However, I must admit that finding the correct wording for this definition has been tough !

With regard to section 35.3.17, I appreciate what you mean, but I'm trying to avoid either referencing or quoting normative text within the definition itself, as I don't believe that this provides a clear definition of what EMLSR operation actually is.

Kind regards

Stephen

Hi Stephen,

Thanks for the contribution 1196r3.

I have a comment on the proposed new definition of EMLSR “A mode of operation that allows a non-access point (non-AP) multi-link device (MLD) with multiple receive chains to listen on a set of enabled links, then switch to one available link within the set, for all of the following frame exchanges. mode of operation that allows a non-access point (non-AP) multi-link device (MLD) with multiple receive chains to listen on a set of enabled links when the corresponding stations (STAs) affiliated with the non-AP MLD are in awake state for an initial Control frame sent by an AP affiliated with an AP MLD in a non-high-throughput (non-HT) (duplicate) physical layer (PHY) protocol data unit (PPDU) with one spatial stream, followed by frame exchanges on the link on which the initial Control frame was received”

My concern is that it tries to define EMLSR operation of listening on the set of links and then “switching” to one of them which entails then the question of switching back, etc. How about an alternate definition as below?

Enhanced multi-link single radio (EMLSR) operation: A mode of operation that allows a non-access point (non-AP) multi-link device (MLD) with multiple receive chains to listen on a set of enabled links called EMLSR links but perform frame exchanges on only one of those links at any time.

A more complete definition requires mentioning other aspects, such as what is already mentioned at the start of section 35.3.17.

Regards,
Shubho
