Question: What is the primary objective of Radio Resource Management (RRM) in Evolved Universal Terrestrial Radio Access Network (E-UTRAN), considering its functional scope?
Option 1: To enhance User Equipment (UE) battery life by minimizing transmission power.
Option 2: To prioritize traffic for emergency services over regular user data.
Option 3: To solely manage handover processes between different E-UTRAN cells.
Option 4: To ensure efficient utilization of available radio resources, meeting E-UTRAN's radio resource related requirements.
Explanation: The correct answer is Option 4 because the primary goal of RRM in E-UTRAN is to optimize the use of limited radio resources. This involves managing (assigning, reassigning, and releasing) these resources efficiently, taking into account both single-cell and multi-cell environments to meet the network's radio resource requirements, as outlined in the specifications for E-UTRAN overall description.
