Question: In BS conformance testing for MIMO mode with four transmit antennas, what is the allowed difference in measured P-CPICH (Primary Common Pilot Channel) powers between any two antenna connectors for carrier frequencies above 3.0 GHz but less than or equal to 4.2 GHz?
Option 1: Within ±1.5 dB
Option 2: Within ±2.0 dB
Option 3: Within ±3.0 dB
Option 4: Within ±4.0 dB
Explanation: This question assesses understanding of specific technical requirements in telecom standards, particularly in the context of Base Station (BS) conformance testing for Multiple Input Multiple Output (MIMO) configurations. The correct answer, "Within ±3.0 dB", reflects the tolerance specified for carrier frequencies between 3.0 GHz and 4.2 GHz, ensuring uniform signal strength across different antenna connectors, which is crucial for maintaining reliable wireless communication links in cellular networks. This tolerance level is a balance between achieving consistent signal quality and accommodating practical limitations in antenna design and deployment.
