Question: In a TDD (Time Division Duplex) scenario, what is the primary objective of transmitting a predefined test signal to a User Equipment (UE) receiver in a static propagation channel setup?
Option 1: To measure the UE's transmit power control accuracy in a multi-cell environment.
Option 2: To evaluate the UE's handover performance between serving and adjacent cells.
Option 3: To verify the UE receiver's ability to achieve a block error ratio (BLER) below a specified threshold for wanted and co-channel signals.
Option 4: To assess the UE's capability to handle dynamic channel switching in a TDD frame structure.
Explanation: This question focuses on the receiver's performance in a controlled, static propagation channel environment. The correct answer aligns with ensuring the UE can receive both wanted and co-channel signals with an acceptable block error ratio (BLER), crucial for reliable data transmission in wireless communications, assessing receiver sensitivity and selectivity.
