Claim Text:
1. An apparatus comprising circuitry configured to cause a first wireless device to: modulate a preamble of a wakeup packet according to an Orthogonal Frequency Division Multiplexing (OFDM) scheme; modulate a payload of the wakeup packet according to an On-Off keying (OOK) modulation scheme over a plurality of OFDM tones of the OFDM scheme; and transmit the wakeup packet to a second wireless device, wherein modulating the payload of the wakeup packet comprises generating an OOK transmit pulse over the plurality of OFDM tones, and modulating a plurality of payload values of the payload by selectively transmitting the OOK transmit pulse during one or more OFDM symbol periods of a plurality of OFDM symbol periods, selectively transmitting the OOK transmit pulse comprises selecting, based on a payload value, whether or not to transmit the OOK transmit pulse over at least one OFDM symbol period.
