Question: In a TDD scenario, as per the 3GPP specifications, when testing the minimum output power of a User Equipment (UE), what is the primary purpose of initially configuring the UE transmitter to enable power control steps of size 1 dB?
Option 1: To rapidly adjust the UE's transmission power in response to changing network conditions.
Option 2: To ensure precise measurement of the UE's minimum output signal, allowing for accurate calibration against reference power levels.
Option 3: To evaluate the UE's ability to handle variable power control step sizes as mandated by different TDD options (e.g., 3.84 Mcps vs. 1.28 Mcps).
Option 4: To simulate real-world power fluctuations experienced in low, mid, and high RF channels.
Explanation: The primary purpose of starting with 1 dB power control steps is to achieve a precise measurement of the UE's minimum output signal. This fine granularity allows for accurate comparison against reference power levels, ensuring the UE meets the specified minimum output power requirements for TDD options, which is crucial for maintaining optimal network performance and minimizing interference.
