Question: In E-UTRA connected to 5GC, which of the following UE states support NR sidelink communication?
Option 1: Only RRC_CONNECTED
Option 2: Only RRC_IDLE and RRC_INACTIVE
Option 3: RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED
Option 4: None of the above states support NR sidelink communication
Explanation: E-UTRA connected to 5GC is designed for flexible connectivity. Supporting NR sidelink in RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED enables seamless V2X communications and other use cases without continuous cellular network connectivity, enhancing network efficiency and user experience, aligning with IoT, autonomous vehicles, and smart infrastructure needs.
