Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may comprise a transceiver configured to transmit uplink frames and receive downlink frames in a first transaction slot of a super-frame. The one or more of the uplink frames and the downlink frames are associated with over-allocated network allocation vectors that reserve a transmission time which exceeds a time required to transmit acknowledgements of the one or more downlink frames or receive acknowledgement of the one or more uplink frames, respectively. The apparatus may comprise a processing system configured to cause the transceiver to transmit a first uplink frame to the access point with a first over-allocated NAV, to establish a start-time for the super-frame and to extract data from two or more downlink frames in a burst received from the access point.
