Question: In FDD inter-band testing for User Equipment (UE) as per 3GPP standards, what determines the selection of primary and secondary FDD bands for a UE that supports multiple FDD bands?
Option 1: Automatically by the UE based on signal strength
Option 2: According to PIXIT parameters
Option 3: Manually by the user through device settings
Option 4: Randomly selected by the testing environment
Explanation: In the context of FDD inter-band testing for UEs that support multiple FDD bands, the selection process for primary and secondary bands is standardized to ensure consistency and reliability in testing outcomes. PIXIT (Protocol Implementation eXtra Information for Testing) parameters provide a structured approach to defining test configurations, making them the appropriate choice for determining band selections in this specific testing scenario. This ensures that tests are conducted under well-defined conditions, facilitating accurate assessment of UE performance across different band combinations.
