Question: In a 5G system, what is a requirement for ranging between two User Equipment (UEs) when using licensed spectrum?
Option 1: The ranging must be initiated by the network operator.
Option 2: The UEs must subscribe to the same service provider.
Option 3: The ranging can occur without any authorization.
Option 4: The ranging is only permitted in full network coverage under the control of the operator providing the coverage.
Explanation: This is correct because, according to the 5G system’s service requirements for ranging, when using licensed spectrum, the system must ensure that ranging is only permitted in network coverage under the full control of the operator who provides the coverage. This ensures security, integrity, and compliance with regulatory requirements, highlighting the importance of controlled network environments for licensed spectrum usage.
