Question: In a Base Station (BS) conformance testing scenario using Test Model 2 (TM2), what is the primary purpose of reducing the code domain power of the Dedicated Physical Channel (DPCH) from `Prated,c - 3 dB` to `Prated,c - 28 dB` in step 4?
Option 1: To simulate a handover scenario between two different base stations.
Option 2: To assess the BS's ability to maintain signal integrity at reduced transmission power levels, reflecting a more realistic operational condition.
Option 3: To test the interference mitigation capabilities of the BS in a multi-cell environment.
Option 4: To evaluate the impact of power reduction on the overall output power of a multi-band capable BS.
Explanation: Reducing the transmission power of the DPCH from `Prated,c - 3 dB` to `Prated,c - 28 dB` allows for the assessment of the Base Station's performance under conditions that are more representative of typical operational scenarios, where maximum power may not always be utilized. This test helps ensure the BS can maintain signal quality and integrity even when transmitting at lower power levels, which is crucial for managing interference, conserving energy, and adapting to varying environmental conditions in real-world telecom networks.
