A method for operating an access point includes receiving information from a first station configured to operate in a non-traffic-indication-map (non-TIM) mode, and determining if downlink data intended for the first station is available at the access point. The method also includes transmitting at least one of the downlink data intended for the first station to the first station, a data indicator indicating that the downlink data intended for the first station is available at the access point, information indicating downlink data is available for the first station, and a time indicator indicating a specific time when the downlink data intended for the first station will be sent to the first station.
