1. A method of wireless communication performed by a user equipment (UE), comprising:
receiving, via a first bandwidth part (BWP) configuration, a control channel that uses an orthogonal frequency division multiplexing (OFDM) waveform;
receiving, via a second BWP configuration, larger than the first BWP configuration, and based at least in part on receiving the control channel, an indicator indicating at least one of a modulation and coding scheme (MCS) for a data channel, or an on-off indicator for the data channel;
receiving, via the second BWP configuration and based at least in part on the indicator, the data channel,
wherein a first filtering configuration is used for the control channel, a second filtering configuration is used for the data channel, and a non-zero gap is present between the control channel and the data channel; and
transmitting or receiving, via the second BWP configuration and based at least in part on receiving the data channel, another data channel,
wherein the UE remains on the second BWP configuration during an entire time period between receiving the data channel and transmitting or receiving the other data channel, and
wherein at least one of the indicator, the data channel, or the other data channel uses a single carrier (SC) waveform.
