Question: In 2nd-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, with the last field mapped to the lowest order information bit.
Option 2: Fields are randomly assigned to information bits, with no specific pattern or sequence.
Option 3: Each field is mapped in the order of its description, with the first field's most significant bit aligned to the lowest order information bit for that field, and successive fields to higher order bits.
Option 4: The mapping starts from the highest order information bit, assigning it to the least significant bit of the last field described.
Explanation: This is correct because fields are mapped in the sequence they appear, with each field's most significant bit starting from the lowest available information bit and progressing to higher order bits for successive fields, ensuring predictable and systematic encoding of information.
