Initial power state after traffic identifier mapping function
This disclosure describes systems, methods, and devices related to initial power state. A device may identify a request frame received from a non-AP MLD on a first link of a plurality of links, wherein the non-AP MLD comprises a plurality of station devices (STAs), and wherein the first link is associated with a first STA of the plurality of STAs. The device may cause to send a response frame to the non-AP MLD on the first link to establish the plurality of links between the device and the non-AP MLD. The device may determine, based on the request frame, a power save mode associated with each of the STAs of the non-AP MLD. The device may communicate with the non-AP MLD based on the power save mode.

10. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising: detecting a link enablement event of one or more links for a first station (STA) affiliated with a non-access point (AP) multi-link device (MLD) comprising a plurality of STAs after a successful MLD association; determining the link enablement event is associated with association request or response frames transmitted on a link of the one or more links; monitor the acknowledgement of the association response frame response frame for the first STA; setting a power management mode of the first STA and the remaining STAs of the plurality of STAs based on link enablement events; setting a power state of the first STA and the remaining STAs of the plurality of STAs based on the power management mode; setting an initial power state of the first STA to an active mode upon enablement of a link through MLD setup and association; and maintaining and updating the power state of the first STA based on transition events.
11. The non-transitory computer-readable medium of claim 10 , wherein the operations further comprise setting the power management mode of the first STA to active mode if a link enablement event is associated with Association Request/Response frames transmitted on the same link.
12. The non-transitory computer-readable medium of claim 10 , wherein the operations further comprise setting the power management mode of the first STA to power save mode if a link enablement event is associated with Association Request/Response frames transmitted on another link or after successful traffic identifier (TID)-to-link mapping negotiation with TID-To-Link Mapping Request/Response frames transmitted on another link.
13. The non-transitory computer-readable medium of claim 10 , wherein the operations further comprise setting the power state of the first STA to doze if the power management mode of the first STA is the power save mode.
14. The non-transitory computer-readable medium of claim 10 , wherein the power management mode comprises an active state or a doze state.
15. The non-transitory computer-readable medium of claim 10 , wherein the device is an access point (AP) multi-link device (MLD).
16. The non-transitory computer-readable medium of claim 10 , wherein the operations further comprise determining the first link is enabled for the first STA based on receiving the request frame.
17. The non-transitory computer-readable medium of claim 10 , wherein the operations further comprise setting up a traffic identifier (TID) associated with data traffic to be exchanged with the non-AP MLD, wherein the setting up of the TID comprises mapping a plurality of TIDs to one or more enabled links of the plurality links.
18. The non-transitory computer-readable medium of claim 17 , wherein the TID comprises a TID mapping update comprising an indication change of an initial power state of the first STA.
