Question: What is the primary condition for a UE (User Equipment) to send an event-triggered measurement report over the Uu interface, according to radio resource management requirements for TDD (Time Division Duplexing)?
Option 1: The UE's battery level falls below a predetermined threshold.
Option 2: The reporting criteria defined in the specifications are fulfilled.
Option 3: A handover to a different base station is initiated by the network.
Option 4: The UE experiences a sudden increase in uplink data traffic.
Explanation: This question assesses understanding of event-triggered reporting in the context of radio resource management for TDD. The correct answer highlights that the UE sends reports only when predefined reporting criteria are met, ensuring efficient network resource use and minimizing unnecessary signaling.
