Question: What is the nature of User Equipment (UE) support for RRCConnectionReject with deprioritisationReq in E-UTRA networks?
Option 1: Mandatory, as it is crucial for efficient resource allocation and load management.
Option 2: Optional, allowing UEs to choose based on their capability and network requirements.
Option 3: Conditional, dependent on the UE's support for specific RRC protocol versions.
Option 4: Not Applicable, as this feature is managed solely by the eNodeB.
Explanation: The correct answer is Optional because UEs are not strictly required to support this feature, providing flexibility in device design and network operation. This allows for a range of device capabilities and network configurations, impacting resource management and service delivery to end-users.
