Question: In Base Station (BS) conformance testing for TDD, what is the allowed differential accuracy range for the Primary CCPCH (Common Control Physical Channel) power, as measured according to specific test procedures?
Option 1: Within 0.6 dB
Option 2: Within 1.2 dB
Option 3: Within 2.0 dB
Option 4: Within 3.0 dB
Explanation: The correct answer is Option 1, as the differential accuracy of the Primary CCPCH power must be within a tight tolerance to ensure reliable and efficient communication in wireless networks. A narrower range (within 0.6 dB) indicates stricter control over signal strength variations, which is crucial for maintaining high-quality service in cellular systems, especially in TDD (Time Division Duplexing) mode where uplink and downlink share the same frequency band, necessitating precise power control to avoid interference.
