Frequency modulated continuous wave-based synchronization signal block and low power synchronization signal

A user equipment (UE), comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
• monitor for low power synchronization signal (LP-SS) signaling associated with an on-off keying (OOK) waveform that comprises a plurality of on durations and a plurality of off durations;
• and
• monitor, during at least a portion of the plurality of on durations of the OOK waveform, for SSB signaling associated with a frequency modulated continuous wave (FMCW) waveform overlaid in the plurality of on durations of the OOK waveform.

A method for wireless communications at a network entity, comprising:

• generating an on-off keying (OOK) waveform associated with communication of low power synchronization signal (LP-SS) signaling, the OOK waveform comprising a plurality of on durations and a plurality of off durations;
• generating a frequency modulated continuous wave (FMCW) waveform associated with communication of synchronization signal block (SSB) signaling;
• and
• transmitting a modulated waveform comprising the FMCW waveform modulated with the OOK waveform on the plurality of on durations of the OOK waveform.
