Abstract
A system and method are provided for coordinating a power-save interval in an IEEE 802.11 wireless network. The method transmits a first frame from an access point (AP) to a quality of service station (QSTA) and receives an acknowledgement from the QSTA. In response to receiving the acknowledgement, the first frame is retransmitted from the AP to the QSTA and the retransmitted first frame is identified as the last frame in the transmission queue. An acknowledgement is received responsive to the retransmitted first frame and the next minimum service interval is timed in response to the retransmitted first frame.
