Question: In E-UTRA FDD operation, what is the primary purpose of the protection requirement for Base Station (BS) receivers?
Option 1: To enhance the transmission power of BS transmitters in densely populated areas.
Option 2: To prevent BS receivers from being desensitized by emissions from a BS transmitter.
Option 3: To ensure seamless handover between different BSs in a network.
Option 4: To reduce interference from User Equipment (UE) transmissions.
Explanation: This is correct because the protection requirement safeguards the receivers of Base Stations (BS) from being desensitized due to emissions originating from a BS transmitter, maintaining optimal receiver performance and overall network quality in E-UTRA FDD operations.
