Question: In a 5G NR (New Radio) network, what is the primary purpose of the 'P-Max' Information Element (IE) in the Radio Resource Control (RRC) protocol?
Option 1: To limit the User Equipment's (UE) uplink transmission power on a specific carrier frequency.
Option 2: To manage the UE's downlink reception sensitivity across different bands.
Option 3: To dynamically adjust the base station's transmit power based on UE feedback.
Option 4: To prioritize traffic for low-latency communications in an ATG (Aerial Telecommunications Grid) cell.
Explanation: The correct answer reflects the primary function of P-Max. By limiting the UE's uplink transmission power on a carrier frequency, P-Max helps manage interference, ensures efficient use of radio resources, and maintains optimal network performance, especially in dense or heterogeneous network deployments.
