Embodiments provide a technique for enabling a wireless device to operate in a power saving mode without completely cutting off the wireless device from receiving outside communications. The technique includes, at an access point (AP), generating traffic indication map (TIM) information that indicates whether downlink data directed to the wireless device is buffered at the AP. The AP precedes a beacon frame with at least one “lightweight” traffic indication map (TIM) frame that includes the TIM information, which is a subset of the information that is included in the beacon frame. The AP can be configured to transmit the TIM broadcast frame, the beacon frame, and any other frames that include the TIM information during a single transmit opportunity to reduce the number of instances where the wireless device is required to transition from an idle state to a listen state.
