AUTOMATIC POWER SAVE DELIVERY (APSD) COMPATIBLE WITH 802.11N FRAME AGGREGATION AND BLOCK ACKNOWLEDGEMENT

摘要

A mechanism to create Automatic Power Save Delivery (APSD) compatible with 802.11 n frame aggregation and block acknowledgement (ack) mechanisms is provided. Various methods of using block acknowledgments are provided. Additionally, bit handling for defining an unscheduled APSD (U-APSD) service period and ending it is explained. A method of aggregating a plurality of data frames into an aggregated data frame, starting a service period based on the transmitting of the aggregated frame, receiving an acknowledgement for the transmitted frame, and upon receiving the acknowledgement frame containing an indicator indicating end of service period, entering low power mode of operation is enabled.
