- the first DCI The payload is aligned with the payload of the second DCI in format1_0 transmitted in the CSS.
- bit padding bits may be added to the first DCI, or appended bits may be added after all valid information fields of the first DCI , so that the processed payload of the first DCI is consistent with the payload of the DCI transmitted in the CSS in the format of format1_0.
- the first DCI may be truncated so that the processed payload of the first DCI is the same as the payload transmitted in the CSS
