Question: What is a requirement for the 5G system to support Public Safety communications?
Option 1: The 5G system shall only support direct device connection between two Public Safety UEs when both are in coverage.
Option 2: The 5G system shall support the relaying of traffic between two remote Public Safety UEs using direct device connection via one or more ProSe UE-to-UE Relay(s), regardless of coverage.
Option 3: The 5G system shall only support direct device connection between two Public Safety UEs when both are out-of-coverage.
Option 4: The 5G system shall not support relaying of traffic between two remote Public Safety UEs using direct device connection.
Explanation: This option is correct because it aligns with the requirement stated in the text, which specifies that the 5G system should support the relaying of traffic between two remote Public Safety UEs using direct device connection via one or more ProSe UE-to-UE Relay(s), regardless of whether they are in coverage, out-of-coverage, or partial coverage. This ensures reliable communication for Public Safety services even in areas with limited network coverage.
