When a user equipment detects a condition that a distance between the user equipment, which has an established connection with a network entity of a communications network system, and a subject enters a pre-warning region, the user equipment enters a monitoring mode based on at least the detected condition. In the monitoring mode, options of operations to be performed by the user equipment to mitigate degradation of the established connection due to a required power backoff of an antenna of the user equipment are monitored.
