Question: What is the primary purpose of the SgNB Resource Coordination Information IE in the context of E-UTRAN?
Option 1: To allocate additional resources from the PCell to the MeNB for enhanced capacity.
Option 2: To inform the MeNB about resources within the PCell's bandwidth that are unavailable for its use, ensuring coordinated resource utilization between en-gNB and MeNB.
Option 3: To initiate handover procedures from the MeNB to the SgNB due to congestion.
Option 4: To request the SgNB to adjust its transmission power to minimize interference with the MeNB.
Explanation: The correct answer highlights the key function of the SgNB Resource Coordination Information IE, facilitating coordinated resource management between the master node (MeNB) and secondary node (en-gNB) by identifying unavailable resources within the Primary Cell's bandwidth, ensuring efficient utilization in a dual-connectivity scenario for maintaining E-UTRAN service quality.
