Power save with data fetch time, with end of data indication, and with more data acknowledgement

An apparatus comprising:

• a processor;
• and
• a memory storing instructions executable by the processor to:
• at an access point, in response to a fetch trigger frame received from a station, transmit a frame that includes an updated beacon version number to the station;
• in response to the fetch trigger frame, fetch one or more data frames associated with the station;
• and
• refrain from transmitting the fetched one or more data frames to the station until determining at the access point that a fetch time associated with the station has elapsed or until a delivery trigger frame is received from the station, wherein the access point is configured to communicate with one or more other stations during the fetch time, and wherein the fetch time is also known at the station.

A non-transitory computer-readable medium comprising instructions that, when executed by a computer, cause the computer to:

• receive a fetch trigger frame from a station at an access point;
• in response to the fetch trigger frame, transmit a frame that includes an updated beacon version number to the station;
• in response to the fetch trigger frame, fetch one or more data frames associated with the station;
• and
• refrain from transmitting the fetched one or more data frames to the station until determining at the access point that a fetch time associated with the station has elapsed or until a delivery trigger frame is received from the station, wherein the access point is configured to communicate with one or more other stations during the fetch time, and wherein the fetch time is also known at the station.

An apparatus comprising:

• means for receiving a fetch trigger frame from a station at an access point;
• means for transmitting, in response to the fetch trigger frame, a frame that includes an updated beacon version number to the station;
• means for fetching, in response to the fetch trigger frame, one or more data frames associated with the station;
• and
• means for refraining from transmitting the fetched one or more data frames to the station until determining at the access point that a fetch time associated with the station has elapsed or until a delivery trigger frame is received from the station, wherein the access point is configured to communicate with one or more other stations during the fetch time, and wherein the fetch time is also known at the station.
