Question: What is the primary goal of using HARQ retransmissions and RLC acknowledged mode in E-UTRAN?
Option 1: To reduce latency and increase packet drops.
Option 2: To ensure reliable packet delivery and maintain a low block error rate or packet error rate.
Option 3: To prioritize packet transmission based on QCI level.
Option 4: To optimize MCS performance for specific services.
Explanation: The primary goal of using HARQ retransmissions and RLC acknowledged mode is to ensure reliable packet delivery, which is critical for a better user experience. By maintaining a low block error rate or packet error rate, the network can provide high-quality services with minimal packet drops. This requires careful monitoring of ARQ and HARQ performance to ensure that these schemes are operating effectively.
