Abstract
Aspects of the disclosure are directed to methods and apparatus for time and frequency synchronization during a low-power wake up signal (LP-WUS) procedure. For example, an LP-WUS procedure may include transmission of signaling modulated via on-off keying (OOK). Such a signal requires less processing relative to an orthogonal frequency division multiplexing (OFDM) modulated signal and can be used to notify a wireless node that the transmitting device has data to transmit to the wireless node via an OFDM transmission. Accordingly, in response to the LP-WUS signal, the wireless node may power-on a main radio capable of receiving and demodulating the OFDM transmission.
