Question: What is one of the key factors considered for selecting and reselecting Relay UEs in a 5G system?
Option 1: Only the capabilities/capacity/coverage when using the relay UE
Option 2: A combination of different criteria, including traffic characteristics, subscriptions, capabilities, QoS, power consumption, pre-paired relay UE, access type, and network optimization
Option 3: The type of 3GPP or non-3GPP access used by the relay UE to connect to the network
Option 4: Only the battery lifetime of the relay UE and remote UE
Explanation: In a 5G system, selecting and reselecting Relay UEs involves considering multiple factors to ensure optimal performance and efficiency. These factors include traffic characteristics, subscriptions, capabilities, QoS, power consumption, pre-paired relay UE, access type, and network optimization. This comprehensive approach ensures that the selected relay UE can effectively support the intended communication while minimizing potential drawbacks such as excessive power consumption or reduced QoS.
