Slot alignment between cyclic-prefix-based waveforms and guard-interval-based waveforms

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving, from a network entity, a configuration of a cyclic prefix (CP) frame structure associated with a CP-based waveform and a guard interval (GI) frame structure associated with a GI-based waveform, wherein the CP frame structure includes multiple CP slots arranged in a half subframe, wherein the GI frame structure includes multiple GI slots arranged in the half subframe, and wherein a first GI slot, of the multiple GI slots, is associated with one of an extra portion, a truncated portion, or a removed portion such that a boundary of the first GI slot aligns with a boundary of a first CP slot, of the multiple CP slots;
• and
• transmitting or receiving a first message in the half subframe via the GI-based waveform using the first GI slot.
