Abstract: Methods, systems, and devices are described for wireless communication at a wireless device. An access point (AP) may identify a pending communication for a wireless device and transmit a wakeup message comprising a device specific sequence to a companion radio of the device. The device may receive the wakeup message using the companion radio, decode the message to obtain a device specific sequence, and activate a primary radio. The wakeup message may include a preamble, a signal field, and a data field. In some cases, the wireless device may demodulate the wakeup message using ON-OFF keying (OOK) modulation. The AP and the device may then exchange data using the primary radio.
