Question: What is the primary purpose of monitoring the Transport Block (TB) Error Rate in both uplink (UL) and downlink (DL) directions?
Option 1: To optimize radio resource scheduling in the physical layer.
Option 2: To estimate the performance of radio resource management in the transport layer and aid in troubleshooting.
Option 3: To directly measure the Bit Error Rate (BER) of user data.
Option 4: To influence Modulation and Coding Scheme (MCS) selection and ultimately affect user throughput.
Explanation: The TB Error Rate is a key performance indicator that reflects the Block Error Rate (BLER), which in turn affects MCS selection. This selection process impacts user throughput, making it essential for optimizing system performance.
