Aspects of a method and system for using power management bits in acknowledgment (ACK) frames received from wireless access points (AP). A STA may exit the power save (PS) mode and transmit a trigger frame to the AP. The trigger frame may comprise an identifier that identifies the STA. The trigger frame may comprise a request that the recipient AP determine whether there is buffered data pending delivery to the STA identified in the trigger frame. In response to the received trigger frame, the AP may transmit to the STA an ACK frame which comprises power management information, the value of which may indicate to the STA that the AP has no data to transmit to the STA. Upon receipt of the ACK frame, the STA may return to the PS mode based on the indication value in the power management information. |
