Question: In a 3GPP-compliant FDD network, during testing of Terminal conformance for Radio transmission and reception, what is the primary objective when evaluating CQI reports based on Transport Format using CQI index 16 on each serving cell?
Option 1: To ensure CQI reports are transmitted with a fixed variance across all serving cells.
Option 2: To verify that the Block Error Rate (BLER) of 10% is consistently below the TF based on cell-specific Median CQI.
Option 3: To confirm that a BLER of 10% falls within a specific range defined by cell-specific Median CQI thresholds (between Median CQI-1 and Median CQI+2, or between Median CQI and Median CQI+2).
Option 4: To test the UE's ability to switch between different CQI indices based on varying network conditions.
Explanation: This question requires understanding of how CQI reports influence transmission formats in wireless communications, specifically in a FDD context. Option 3 is correct because it accurately reflects the test purpose: ensuring that a Block Error Rate (BLER) of 10% is achieved within a defined range of cell-specific Median CQI values, which is crucial for balancing between reliable transmission and efficient use of radio resources, impacting the network's ability to manage quality of service (QoS) effectively.
