Wireless communications systems, apparatuses, and methods are provided. A method of wireless communication performed by a user equipment (UE) includes receiving, from a network unit, an indicator indicating dynamic waveform switching between a first waveform type and a second waveform type and monitoring, based on the indicator, for downlink control information (DCI) from the network unit, wherein at least one of a size of the DCI, a size of a bitfield of the DCI, or a location of the bitfield of the DCI is interpreted based on the indicator.
