Question: In a TDD (Time Division Duplex) scenario, what is the minimum required rate of successful RRC (Radio Resource Control) re-establishments observed during repeated tests?
Option 1: At least 90%
Option 2: At least 95%
Option 3: At least 80%
Option 4: At least 75%
Explanation: Ensuring reliable communication, the minimum threshold of 90% for successful RRC re-establishments is crucial. This percentage reflects a balance between network robustness and the inevitability of occasional re-establishment failures due to various wireless communication impairments. Exceeding this threshold indicates better network performance, but meeting at least this 90% benchmark is the specified requirement for conformance in TDD scenarios as outlined in telecom standards.
