    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may interrupt a user equipment (UE) during transport block (TB) encoding. The UE may cancel transmission (e.g., suppress processing) of a TB based on the interruption, such that a first subset of code blocks is encoded and a second subset is unencoded. In some cases, the UE may receive a re-transmission request for a code block including cyclic redundancy check (CRC) bits for the TB, where the CRC bits are not prepared. In one example, the UE may modify the CRC bits (e.g., set them to a common value, drop them, etc.) to reduce processing time. In another example, the base station may request re-transmission of all preempted code blocks, supporting TB CRC calculation. In another example, the base station or UE may extend a processing timeline for the re-transmission to support TB CRC calculation.
