1. An apparatus for wireless communications 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:
receive, from a base station, control signaling comprising a configured grant scheduling a first uplink channel during a first time slot, the first time slot different from a second time slot scheduled for transmission of a second uplink channel;
generate dummy data for the first uplink channel based at least in part on information associated with the configured grant failing to satisfy a transmission criterion; and
transmit, to the base station, the dummy data and a first plurality of demodulation reference signals in the first uplink channel during the first time slot and a second plurality of demodulation reference signals in the second uplink channel during the second time slot, the first plurality of demodulation reference signals and the second plurality of demodulation reference signals having phase continuity.
