Question: In NR (New Radio) DCI (Downlink Control Information) transmissions, how are the CRC (Cyclic Redundancy Check) parity bits, computed with a generator polynomial, further processed after attachment to the payload?
Option 1: They are encrypted using the UE's (User Equipment) public key.
Option 2: They remain unchanged for direct transmission.
Option 3: They are scrambled with the corresponding RNTI (Radio Network Temporary Identifier).
Option 4: They are concatenated with additional error correction bits.
Explanation: In NR DCI transmissions, after CRC parity bits are computed and attached to the payload, they undergo an additional processing step. This involves scrambling the CRC parity bits with the corresponding RNTI, a unique identifier used in the radio network. Scrambling with RNTI ensures the error detection mechanism is tightly coupled with the identity of the intended recipient or transmission purpose, adding security and specificity to the communication.
