Question: What is the primary purpose of the 'Max Adjustment Step' parameter in the UTRAN Iur interface RNSAP signalling?
Option 1: To define the minimum transmission power for User Equipment (UE) in the downlink.
Option 2: To set a threshold for the uplink power control loop adjustment.
Option 3: To determine the maximum number of slots for handover decisions.
Option 4: To limit the cumulative change in Downlink (DL) power level over a specified number of slots for power balancing.
Explanation: The 'Max Adjustment Step' parameter restricts how much the downlink power level can be adjusted within a defined timeframe, excluding inner loop power control adjustments, to manage and limit cumulative changes in DL power for effective power balancing.
