Configurable cyclic prefix lengths for single carrier waveforms

An apparatus for wireless communications, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a configuration message indicating a user equipment (UE)-specific cyclic prefix length for communicating with a network device, wherein the UE-specific cyclic prefix length is different from a nominal cyclic prefix length associated with a numerology of a radio access technology for the UE;
• and
• communicate with the network device using a single carrier waveform and a cyclic prefix based at least in part on the UE-specific cyclic prefix length, wherein the communicating comprises transmitting or receiving a signal in one or more symbols of the single carrier waveform aligning in a time domain with one or more corresponding symbols of a reference orthogonal frequency division multiplexing waveform.
