Question: In a non-collocated Radio Cloud Lightweight Wireless Infrastructure (RCLWI) scenario, what is the primary purpose of the Xw control plane interface (Xw-C) defined between the eNB (Evolved Node B) and the WT (Wireless Terminal)?
Option 1: To support LWA (LTE-WiFi Aggregation) specific functions for enhanced throughput.
Option 2: To enable communication for RCLWI control plane signaling, excluding LWA specific functions.
Option 3: To facilitate user plane data transfer between eNB and WT in a collocated architecture.
Option 4: To manage the handover process from LTE to WiFi networks.
Explanation: In the context of RCLWI, especially in non-collocated scenarios, the Xw-C interface facilitates control plane signaling for RCLWI, excluding LWA's specific functionalities, adapting to RCLWI's unique operational needs.
