1. A wireless station (STA) device comprising:
a transceiver configured to transmit and receive signals; and
a processor operably coupled to the transceiver, the processor configured to generate a traffic profile request element that comprises an indication of a request for an access point (AP) to provide, to the STA, traffic characteristics, as observed at the AP, of downlink (DL) traffic between the AP and the STA, wherein the traffic characteristics are not known to the STA at a time the traffic profile request element is generated,
wherein the transceiver is further configured to transmit to the AP the traffic profile request element, and
wherein the requested traffic characteristics are used to determine target wake time (TWT) parameters for a TWT operation between the AP and the STA.
