Question: For a 3.84 Mcps TDD User Equipment (UE), what determines the receive characteristic of the Master Control Channel (MCCH)?
Option 1: Transmission Power Control (TPC) accuracy
Option 2: Signal-to-Noise Ratio (SNR) of the downlink shared channel
Option 3: Service Data Unit (SDU) error rate (SDU_ER)
Option 4: Round Trip Time (RTT) measurement accuracy
Explanation: The receive characteristic of the Master Control Channel (MCCH) in a 3.84 Mcps TDD UE is directly tied to the reliability and integrity of the data it receives, which is quantitatively measured by the Service Data Unit error rate (SDU_ER). This metric effectively determines how well the UE can accurately receive and process MCCH information, impacting overall network performance and user experience.
