Question: In a carrier aggregation scenario for FDD (Frequency Division Duplexing), what aspects of RSRP (Reference Signal Received Power) accuracy are verified in the test for primary and secondary component carriers?
Option 1: Absolute RSRP accuracy of primary component carrier, absolute and relative RSRP accuracy of secondary component carriers, and relative RSRP accuracy between primary and secondary carriers.
Option 2: Only absolute RSRP accuracy for all component carriers without considering relative accuracies.
Option 3: Relative RSRP accuracy among secondary component carriers but not the absolute accuracy or the comparison with the primary carrier.
Option 4: Absolute RSRP accuracy of secondary component carriers and relative RSRP accuracy between primary and one secondary carrier.
Explanation: This option correctly encompasses all verified aspects as stated in the test purpose: the absolute RSRP accuracy for the primary component carrier, both absolute and relative RSRP accuracies for the secondary component carriers, and the relative RSRP accuracy requirement between the primary and secondary component carriers. This comprehensive verification ensures that carrier aggregation operates within specified limits for reliable network performance.
