Question: Which of the following statements accurately describes the primary purpose of RLC Control PDUs in the Radio Link Control (RLC) protocol?
Option 1: To transfer upper layer PDUs (RLC SDUs) for all RLC entities (TM, UM, and AM).
Option 2: To manage the configuration of RLC entities within a User Equipment (UE).
Option 3: To handle segmentation of large RLC SDUs across multiple RLC data PDUs.
Option 4: To perform Automatic Repeat Request (ARQ) procedures specifically for Acknowledged Mode (AM) RLC entities.
Explanation: This is correct because RLC Control PDUs are utilized by the Acknowledged Mode (AM) RLC entity to execute ARQ (Automatic Repeat Request) procedures, ensuring reliable data transfer through error correction and retransmission mechanisms.
