Another particular method includes transmitting a frame from the station to the access point indicating that the station is to enter the power save mode and refraining from entering the power save mode until receipt of an end of data frame. Yet another particular method includes receiving a fetch trigger frame at an access point and refraining from transmitting one or more fetched data frames from the access point until a fetch time has elapsed or a delivery trigger frame is received. The access point is configured to communicate with other stations during the fetch time.
