Mixed-waveform communications

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

• determining a first waveform type to use for a first portion of a synchronization signal block, a second waveform type to use for a second portion of the synchronization signal block, and a third waveform type to use for a third portion of the synchronization signal block, wherein the first portion comprises a primary synchronization signal, the second portion comprises a secondary synchronization signal, and the third portion comprises a physical broadcast channel, and wherein the second waveform type is different than the first waveform type and the third waveform type is different from the first waveform type and the second waveform type;
• generating, based at least in part on the determining, the first portion of the synchronization signal block in accordance with the first waveform type, the second portion of the synchronization signal block in accordance with the second waveform type, and the third portion of the synchronization signal block in accordance with the third waveform type;
• and
• transmitting the synchronization signal block based at least in part on the generating.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• monitor communication resources for synchronization signal block transmissions;
• and
• receive, based at least in part on the monitoring, a synchronization signal block that comprises a first portion generated in accordance with a first waveform type, a second portion generated in accordance with a second waveform type that is different than the first waveform type, and a third portion generated in accordance with a third waveform type that is different from the first waveform type and the second waveform type, wherein the first portion comprises a primary synchronization signal, the second portion comprises a secondary synchronization signal, and the third portion comprises a physical broadcast channel, and wherein to receive the synchronization signal block, the instructions are further executable by the processor to cause the apparatus to:
• detect, based at least in part on the monitoring, the first portion of the synchronization signal block based at least in part on the first waveform type;
• and
• process, based at least in part on the detecting, the second portion of the synchronization signal block in accordance with the second waveform type based at least in part on information obtained from the first portion.
