Question: Which of the following statements about RRC message segmentation in E-UTRAN is INCORRECT?
Option 1: Segmentation occurs when the encoded RRC message PDU exceeds the maximum PDCP SDU size.
Option 2: Each segment of an RRC message is carried in a separate RLC PDU.
Option 3: The receiver is responsible for reassembling the segments to form the complete RRC message.
Option 4: In this version of the specification, all types of RRC messages support segmentation in both uplink and downlink.
Explanation: According to the specifications, segmentation applies only to specific RRC messages, not all types of RRC messages, making Option 4 incorrect as it suggests universal application of segmentation across all RRC message types.
