Question: In 1st-stage SCI formats for NR (New Radio), how are the fields within each format mapped to information bits?
Option 1: Each field is mapped in reverse order of its description, starting from the highest order information bit.
Option 2: Each field is mapped in the order it appears, with the first field starting from the lowest order information bit, and the most significant bit of each field being its lowest order bit.
Option 3: Fields are randomly assigned to information bits, with no specific pattern for ordering or significance within each format.
Option 4: The mapping starts from the middle of the information bits, moving outward in both directions as fields are added.
Explanation: This is correct because fields in 1st-stage SCI formats are mapped sequentially as described, with the first field being assigned to the lowest order information bits. Within each field, the most significant bit is aligned with the lowest order information bit, ensuring a structured and predictable mapping approach for efficient encoding and decoding in NR communications.
