Question: What is the primary condition for cell re-selection delay in a User Equipment (UE) to ensure conformance with Radio Resource Management requirements in an E-UTRAN?
Option 1: The cell re-selection delay shall be less than 5.7 seconds, with a correct reselection rate of at least 90%
Option 2: The UE must complete cell re-selection within 3 seconds for a minimum of 80% of attempts
Option 3: Cell re-selection is considered successful if it occurs within 10 seconds, with no specified minimum success rate
Option 4: The delay for cell re-selection is not standardized but should ideally be as short as possible
Explanation: This option correctly reflects the stringent requirements for cell re-selection in E-UTRAN, balancing both the time constraint (less than 5.7 seconds) and the reliability aspect (at least 90% correct reselection rate). These specific parameters are crucial for ensuring seamless network handovers and maintaining service quality, aligning with the objectives of Radio Resource Management in telecom networks.
