Question: What is the purpose of the IE NRDC-Parameters in the RRC protocol specification?
Option 1: To contain parameters specific to NR SA.
Option 2: To provide general parameters applicable to all radio access technologies.
Option 3: To contain parameters specific to NR-DC, which are not applicable to NR SA.
Option 4: To define the structure of the RRC protocol messages.
Explanation: The IE NRDC-Parameters is used to contain parameters that are specific to NR-DC (New Radio Dual Connectivity) and are not applicable to NR SA (New Radio Standalone). This information element is used to convey parameters related to dual connectivity, such as measurement and mobility parameters, general parameters, and UE capabilities.
