Question: In E-UTRA carrier aggregation, what aspects of RSRP (Reference Signal Received Power) accuracy are verified in a test for compliance with specified limits?
Option 1: Only the absolute RSRP accuracy of the primary component carrier.
Option 2: The absolute RSRP accuracy of both primary and secondary component carriers, but not their relative accuracy.
Option 3: The relative RSRP accuracy between primary and secondary component carriers, but not the absolute accuracy of either.
Option 4: Both the absolute and relative RSRP accuracy requirements for primary and secondary component carriers.
Explanation: In E-UTRA carrier aggregation, ensuring accurate power measurements is crucial for effective resource management. Verifying both the absolute RSRP accuracy (how accurately the power of each carrier is measured against a known reference) and the relative RSRP accuracy (the comparison of power levels between different carriers) for all component carriers (both primary and secondary) is essential for maintaining network performance and user experience. Thus, a comprehensive test would logically cover both aspects for all types of carriers involved in the aggregation.
