Question: In the context of 3GPP terminal conformance specification for Radio transmission and reception (TDD), what is the primary focus of the performance requirement regarding receiver testing?
Option 1: To assess the RF hardware's ability to filter out co-channel interference from adjacent cells.
Option 2: To evaluate the transmitter's power control capabilities in varying propagation conditions.
Option 3: To determine the receiver's sensitivity in detecting weak signals from serving cells only.
Option 4: To verify the receiver's signal processing capability in handling wanted and co-channel signals with a specified block error ratio (BLER).
Explanation: This question requires understanding of telecom testing protocols. The correct answer highlights the test's focus on the receiver's ability to process signals effectively under defined conditions, demonstrating nuanced understanding of telecom testing objectives.
