Question: In the context of measuring Total Radiated Sensitivity (TRS) for a User Equipment (UE), what is the primary purpose of sending PN15 data pattern to the UE after it reaches maximum power during the sensitivity measurement procedure?
Option 1: To simulate real-world data transmission scenarios and assess UE's performance under load.
Option 2: To achieve a specific Bit Error Rate (BER) value, in this case, 1% or 0.2%, for accurate EIS (Equivalent Isotropic Sensitivity) measurement.
Option 3: To test the UE's power control capabilities and ensure it operates within specified limits.
Option 4: To initialize the UE's antenna for far-field measurements on a spherical surface.
Explanation: Sending a PN15 data pattern is aimed at achieving a targeted Bit Error Rate (BER) of 1% or 0.2%, crucial for accurately measuring the Equivalent Isotropic Sensitivity (EIS) of the UE, which is essential for calculating the Total Radiated Sensitivity (TRS). The PN15 data pattern serves as a standardized test signal for reliable and comparable sensitivity measurements across different UEs.
