1. A method comprising:
- buffering, by an access point, data for a first station;
receiving, by the access point, a first frame from the first station after buffering the data, the first frame including a trigger frame indicating that the first station is to enter and exit a power save mode;
transmitting, by the access point, one or both of an acknowledgment indicating receipt of the first frame and an indication of a fetch time period to the first station, an end of the fetch time period indicating one or both of exiting the power save mode and starting a service period of the access point; and
transmitting, by the access point, one or more frames to one or more other stations but not to the first station during the fetch time period after receiving the first frame.

Abstract
A particular method includes receiving a first frame from a station at an access point indicating that the station is to enter a power save mode. The method also includes transmitting one or more data frames from the access point to the station. The one or more data frames were buffered for transmission prior to receipt of the first frame. The method further includes transmitting an end of data frame to the station. Another particular method includes transmitting a first frame from the station to the access point indicating that the station is to enter the power save mode. The method also includes refraining from entering the power save mode until an end of data frame is received from the access point.

1. A method comprising:
-
buffering, by an access point, data for a first station; receiving, by the access point, a first frame from the first station after buffering the data, the first frame including a trigger frame indicating that the first station is to enter and exit a power save mode; transmitting, by the access point, one or both of an acknowledgment indicating receipt of the first frame and an indication of a fetch time period to the first station, an end of the fetch time period indicating one or both of exiting the power save mode and starting a service period of the access point; and transmitting, by the access point, one or more frames to one or more other stations but not to the first station during the fetch time period after receiving the first frame. - View Dependent Claims (2, 3, 4, 5, 6)

7. A method comprising:
-
after transitioning from a power save mode, transmitting, by a station, a first frame to an access point, the first frame including a trigger frame indicating that the station is to enter and exit the power save mode; receiving at the station from the access point one or both of an acknowledgment indicating receipt of the first frame and an indication of a fetch time period, an end of the fetch time period indicating one or both of exiting the power save mode and starting a service period of the access point; and receiving at the station one or more data frames from the access point after the first frame during the service period but not during the fetch time period. - View Dependent Claims (8, 9, 10, 11)

12. An apparatus comprising:
-
a processor; and a memory storing instructions executable by the processor to perform operations comprising; buffering, by an access point, data for a first station; receiving, by the access point, a first frame from the first station after buffering the data, the first frame including a trigger frame indicating that the first station is to enter and exit a power save mode; transmitting one or both of an acknowledgment indicating receipt of the first frame and an indication of a fetch time period to the first station, an end of the fetch time period indicating one or both of the exit from the power save mode and a start time of a service period of the access point; and transmitting, by the access point, one or more frames to one or more other stations but not to the first station during the fetch time period after receipt of the first frame. - View Dependent Claims (13, 14, 15)

16. A non-transitory computer-readable medium comprising instructions that, when executed by a computer, cause the computer to perform operations comprising:
-
buffering, by an access point, data for a first station; receiving a first frame from the first station after buffering the data, the first frame including a trigger frame indicating that the first station is to enter and exit a power save mode; transmitting one or both of an acknowledgment and an indication of a fetch time period to the first station, an end of the fetch time period indicating one or both of exiting the power save mode and starting a service period of the access point; and transmitting, by the access point, one or more frames to one or more other stations but not to the first station during the fetch time period after receiving the first frame. - View Dependent Claims (17, 18)

19. An apparatus comprising:
-
means for receiving a first frame from a first station at an access point after buffering data for the first station at the access point, the first frame including a trigger frame indicating that the first station is to enter and exit a power save mode; and means for transmitting one or both of an acknowledgment indicating receipt of the first frame and an indication of a fetch time period to the first station, an end of the fetch time period indicating one or both of the exit from the power save mode and a start time of a service period of the access point, and for transmitting one or more frames to one or more other stations but not to the first station during the fetch time period after receipt of the first frame. - View Dependent Claims (20, 21)

22. An apparatus comprising:
-
a processor; and a memory storing instructions executable by the processor to perform operations comprising; after a transition of a station from a power save mode, transmitting, by the station, a first frame to an access point, the first frame including a trigger frame indicating that the station is to enter and exit the power save mode; receiving at the station from the access point one or both of an acknowledgment indicating receipt of the first frame and an indication of a fetch time period, an end of the fetch time period indicating one or both of the exit from the power save mode and a start time of a service period of the access point; and receiving at the station one or more data frames from the access point after the first frame during the service period but not during the fetch time period. - View Dependent Claims (23, 24)
