Abstract:
Systems and methods are provided for coordinating power management states in a wireless communications device. An access point may buffer data for a station and may then initiate transfer of the buffered data to the station when the station is considered to be in active mode. The access point may transmit each of the one stored data frames with a more data indication when at least one additional frame is buffered and with a no more data indication when no additional frames are buffered. Receipt of the terminal frame including the no more data indication allows the station to return to power save mode without waiting for any timeout period and without risking missing a transmission from the access point.
