Intra-device collision handling

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:
• receiving a first downlink message indicating a set of code blocks allocated for receiving a downlink shared channel at the UE;
• wherein at least a portion of the set of code blocks is preempted by a second downlink message;
• assign an acknowledgement bit to each code block that is at least partially preempted by the second downlink message;
• assign either an acknowledgement bit or a negative acknowledgement bit for each of the set of code blocks that are not at least partially preempted;
• and
• transmit one or more feedback messages to report feedback for the set of code blocks, wherein the one or more feedback messages include respective acknowledgement bits or respective negative acknowledgement bits assigned to each of the set of code blocks.
