Dear all,
I am writing as I am trying to create and simulate IEEE 802.11ax networks with ns-3, while using the latest ns-3 release.
I am aware of the current limitations of the IEEE 802.11ax model, as reported in the official documentation: https://www.nsnam.org/docs/models/html/wifi-design.html
However, one relatively new feature of IEEE 802.11ax I would be very interested in is the Target Wait Time (TWT), enabling devices to better manage their sleep and active times, and letting them "sleep" at given times, to save energy and reduce contention.
While looking at the code inside "wifi", I found some references to TWT inside he-capabilities.cc/.h (used, if I got it correctly, to fill in the HE capabilities information in the message headers) and he-operations.h. However, I couldn't find it in any other file, and there is no reference to it in the documentation of the "wifi" module.
My question is thus whether TWT is already supported in ns-3.38, for IEEE 802.11ax. If yes, am I looking at the wrong files to understand how it could be included in an IEEE 802.11ax simulation? If not, is there any plan to support it in the near future, or any suggestion on which parts of the "wifi" model I should possibly modify to try to integrate this feature?
Thanks a lot in advance.

Hi , Did you find any anything about TWT implementation in ns3 ?
