Question: For a UE (User Equipment) supporting DC-HSDPA (Dual Carrier High Speed Downlink Packet Access) with 64QAM (64-Quadrature Amplitude Modulation), what is the primary criterion for determining the Maximum Input Level for DC-HSDPA reception?
Option 1: The maximum power received at the UE antenna port without degrading specified DC-HSDPA throughput performance.
Option 2: The minimum signal-to-noise ratio required for reliable data transmission.
Option 3: The highest data rate achievable under optimal network conditions.
Option 4: The lowest power consumption of the UE during idle mode.
Explanation: This option is correct because the Maximum Input Level for DC-HSDPA reception is defined by its impact on throughput performance, ensuring received power at the UE's antenna does not compromise expected data throughput speeds for DC-HSDPA with 64QAM, maintaining service quality and user experience in terms of data transfer rates.
