Question: What is the primary purpose of the 'Max Adjustment Step' parameter in the UTRAN Iub interface Node B Application Part (NBAP) signalling?
Option 1: To define the minimum transmission power for User Equipment (UE) in downlink communications.
Option 2: To set a threshold for the uplink noise floor to trigger interference mitigation techniques.
Option 3: To determine the step size for adjusting the antenna tilt in Node B.
Option 4: To limit the maximum allowed change in Downlink (DL) power level over a specified number of slots for power balancing.
Explanation: The 'Max Adjustment Step' is about constraining the cumulative adjustment of downlink power levels within a certain time frame to prevent sudden significant changes, ensuring balanced and controlled adjustments in the downlink direction.
