Question: In a TDD (Time Division Duplexing) network, what is the minimum required rate of correct cell re-selections to ensure compliance with the specified radio resource management requirements?
Option 1: At least 75% of observed re-selections during repeated tests
Option 2: At least 80% of observed re-selections during repeated tests
Option 3: At least 85% of observed re-selections during repeated tests
Option 4: At least 90% of observed re-selections during repeated tests
Explanation: Ensuring a high rate of correct cell re-selections is crucial for maintaining seamless connectivity and efficient resource allocation in TDD networks. The requirement of at least 90% correct cell re-selections during repeated tests reflects the stringent standards for reliable radio resource management, directly impacting user experience and network performance. This threshold ensures that User Equipment (UE) can effectively re-select cells, minimizing dropped calls and service interruptions.
