Abstract
Methods, systems, and devices are described for using low energy (LE) signaling to indicate to a wireless station (STA), prior to transmission of a beacon, whether the beacon will further indicate that an access point (AP) has data to transmit to the STA. In one aspect, a method may include receiving, using a first radio of a wireless STA using a LE communication protocol, a first signal comprising an indication of a traffic indication map (TIM) of a wireless local area network (WLAN) beacon, and selectively powering up a second radio of the wireless STA to receive the WLAN beacon in response to the indication. In one aspect, the wireless STA may power up the first radio at a predetermined interval prior to a target beacon transmission time (TBTT) of the WLAN beacon.
