Hi Patrice,
Thanks for your comments.
The latest contribution proposes to specify a Latency Sensitive Traffic KPI element used to identify the currently supported
latency sensitive traffic by AP, not to differentiate latency sensitive traffic and other types of traffic.
AP can determine the KPIs from its perspective based on the current network conditions and BSS load etc., and advertises the KPIs via the element.
STAs can use the KPIs as a reference to consider whether it is suitable to deliver LL traffic or decide whether to deliver LL traffic in the BSS by SCS or R-TWT, as you mention.
And how to compute the KPIs depends on the implementation of AP. R-TWT as a mechanism for the delivery of LL traffic can be considered by AP for computing the KPIs.
Best regards,
Liuming Lu

Hi Liuming,
Thanks for your presentation and for initiating the discussion about this topic.
If I understand well, the KPIs are computed based on the network load, the rTWT parameters and the low-latency traffics parameters known
by the AP. This is an interesting concept. Nevertheless, it seems that the computed KPI allows to define the average flows that can be supported by a BSS, not dedicated for low latency flows. It is not a way to prioritize the low latency flows versus the other
types of flows.
It is helpful mainly for the STAs to know if its low-latency flows can be transmitted or not within the BSS. For me, the rTWT mechanism
is a way to prioritize the low latency flows.
Regards.
Patrice
