Question: For a UE (User Equipment) supporting DC-HSDPA (Dual Carrier High Speed Downlink Packet Access) with 16QAM (Quadrature Amplitude Modulation), what is the primary criterion for determining the Maximum Input Level for DC-HSDPA reception?
Option 1: The minimum power required at the UE antenna port to achieve a specific data rate.
Option 2: The maximum power received at the UE antenna port, beyond which the specified DC-HSDPA throughput performance degrades.
Option 3: The average signal strength over a defined period to ensure reliable connectivity.
Option 4: The minimum Signal-to-Noise Ratio (SNR) required for error-free data transmission.
Explanation: This option correctly identifies the primary criterion for determining the Maximum Input Level for DC-HSDPA reception, which is centered around preventing degradation of the specified throughput performance. This aligns with the telecom concept of ensuring optimal network and device performance by setting thresholds for signal strength that balance between maximizing capacity and minimizing interference or performance drops.
