Techniques for conveying on-off keying signaling via orthogonal frequency division multiplexing waveforms

An apparatus for wireless communications at a network entity, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• map a plurality of on-off keying symbols of an on-off keying sequence to an orthogonal frequency division multiplexing waveform, the orthogonal frequency division multiplexing waveform includes at least one orthogonal frequency division multiplexing symbol with a cyclic prefix, each on-off keying symbol of the plurality of on-off keying symbols is mapped to at least one segment of a first integer quantity of segments of the orthogonal frequency division multiplexing waveform based at least in part on an on-off keying data rate, wherein the on-off keying data rate is based at least in part on a ratio between a duration of the cyclic prefix and a duration of a remainder of the at least one orthogonal frequency division multiplexing symbol;
• and
• output the orthogonal frequency division multiplexing waveform via a set of frequency resources, wherein a duration of each segment of the first integer quantity of segments of the orthogonal frequency division multiplexing waveform is based at least in part on the on-off keying data rate and the ratio between the duration of the cyclic prefix and the duration of the remainder of the at least one orthogonal frequency division multiplexing symbol.
