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 control signaling to perform a cell switch between a first cell and a second cell of a cell group;
receive a downlink data message during a first time interval that occurs prior to a bandwidth part switch, wherein a second time interval after the first time interval is allocated for a feedback message associated with the downlink data message; and
transmit a feedback message according to a feedback scheme, wherein the feedback scheme indicates whether to exclude or include feedback information corresponding to the downlink data message based at least in part on one or more of the cell switch, a bandwidth part switch, or which of the first cell or the second cell the feedback message is scheduled for transmission.
