1. A station comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, cause the station to:
determine, based at least in part on information received from an access point, a period of time to delay entering a power save mode when the station has indicated that it is entering the power save mode;
transmit a power management frame to the access point to indicate that the station is entering the power save mode, wherein the power management frame includes power save delay information specifying the period of time that the station will delay entering the power save mode after transmission of the power management frame;
enter the power save mode after transmitting the power management frame and waiting the period of time specified by the power save delay information;
exit the power save mode to receive a beacon from the access point;
determine whether the access point has buffered data for the station based on the received beacon; and
when the access point has buffered data for the station, transmit a power save poll message to the access point to retrieve the buffered data.
