Question: What is a key characteristic of a UE 2 device in the context of Mission Critical (MC) services over a 5G System?
Option 1: Utilization of 5G ProSe UE-to-network relay and support for one or more MC service-related applications.
Option 2: Exclusive operation on 4G networks with fallback to 3G for MC services.
Option 3: Dependency on satellite communication for all MC service transmissions.
Option 4: Limitation to only one type of MC service (e.g., either voice or data, but not both).
Explanation: UE 2 is specifically defined by its ability to leverage 5G ProSe UE-to-network relay capabilities, enhancing suitability for mission-critical communications. Supporting applications related to one or more MC services underscores its primary function within the context of Mission Critical services over a 5G System.
