Abstract

A method, apparatus and computer program product are provided for enabling wireless data transmission. In this regard, a method is provided that comprises causing an uplink data transmission. The method of this embodiment may also include decoding an acknowledgement message received from an access point in response to the uplink transmission, the acknowledgement message configured to indicate that downlink data is buffered at the access point. The method of this embodiment may also include receiving downlink data, wherein the downlink data is transmitted by the access point following a predetermined time interval after the acknowledgement message.
