Abstract
A method for power save optimization includes a wireless station receiving a beacon frame from an Access Point (AP), wherein the beacon frame comprises a Traffic Indication Map (TIM) including an Association Identifier (AID) flag corresponding to the wireless station. The wireless station transmits to the AP, a first NULL frame with a Power Save (PS) flag cleared to represent an AWAKE state if the AID flag is TRUE, otherwise the PS flag is set to represent a DEEP SLEEP state. The wireless station receives at least a portion of a data from the AP in response to the AP receiving the first NULL frame during the AWAKE state. The wireless station transmits to the AP, a second NULL frame with the PS flag set to represent the DEEP SLEEP state in response to the wireless station receiving all of the data.
