Question: In the context of 3GPP NR (New Radio), what is the correct sequence of processing steps for Downlink Control Information (DCI) that transports control information for one or more cells with a single Radio Network Temporary Identifier (RNTI)?
Option 1: - Channel Coding - Rate Matching - Information Element Multiplexing - CRC Attachment
Option 2: - Information Element Multiplexing - CRC Attachment - Channel Coding - Rate Matching
Option 3: - Rate Matching - Channel Coding - CRC Attachment - Information Element Multiplexing
Option 4: - CRC Attachment - Information Element Multiplexing - Rate Matching - Channel Coding
Explanation: Option 2 is the correct sequence because it logically follows the necessary steps to prepare and transmit DCI efficiently and reliably: Information Element Multiplexing combines control information elements; CRC Attachment adds error detection; Channel Coding protects against transmission errors; and Rate Matching optimizes resource usage. This sequence ensures accurate, protected, and efficient conveyance of control information.
