Methods, architectures, apparatuses and systems for waveform generation of wake-up radio (wur) signals

A method, comprising:

• receiving, from an access point (AP), a physical protocol data unit (PPDU) comprising a wake up radio (WUR) portion and a non-WUR portion, the WUR portion comprising a WUR signal occupying a first plurality of resource units (RUs), wherein the WUR signal includes orthogonal frequency division multiplexing (OFDM) modulated information and on-off-keying (OOK) modulated information, and the non-WUR portion comprising OFDM signals occupying a second plurality of resource units (RUs), wherein the WUR signal uses a same guard interval and OFDM symbol duration as the OFDM signals, the WUR signal and OFDM signals being orthogonal to each other in a frequency domain;
• and
• demodulating one of the OFDM modulated information or the OOK modulated information included in the WUR signal.

A method, comprising:

• transmitting, to a station (STA), a physical protocol data unit (PPDU) comprising a wake up radio (WUR) portion and a non-WUR portion, the WUR portion comprising a WUR signal occupying a first plurality of resource units (RUS), and the non-WUR portion comprising orthogonal frequency division multiplexing (OFDM) signals occupying a second plurality of resource units (RUs), wherein the WUR signal uses a same guard interval and OFDM symbol duration as the OFDM signals, the WUR signal and OFDM signals being orthogonal to each other;
• and
• modulating the first plurality of RUs of the WUR portion and the second plurality of RUs of the non-WUR portion by a single orthogonal multicarrier transmitter, wherein the modulated first plurality of RUs include OFDM modulated information and on-off-keying (OOK) modulated information.
