Question: In E-UTRA, what is the primary purpose of attaching a CRC (Cyclic Redundancy Check) to each code block after segmentation from a transport block?
Option 1: To facilitate faster transmission by reducing error correction overhead
Option 2: To enable prioritization of code blocks for selective retransmission
Option 3: To increase the overall size of the transmitted data for enhanced security
Option 4: To detect errors introduced during transmission at the code block level, ensuring integrity
Explanation: Attaching a CRC to each code block after segmentation allows the receiver to detect errors that may have occurred during transmission specifically within each code block. This ensures data integrity at a granular level, enabling targeted retransmissions if needed, and is a crucial aspect of reliable data transfer in E-UTRA networks.
