1. A method for use by a user equipment, the user equipment comprising a plurality of antenna devices for covering sectors around the user equipment, the plurality of antenna devices of the user equipment comprising a connected antenna device that operates an established connection with a network entity of a communications network system, the method comprising:
measuring, by at least one non-connected antenna device of the plurality of antenna devices, which is different from the connected antenna device and is capable of detecting a subject, a distance between the subject and the at least one non-connected antenna device;
detecting, based on the measuring, that the distance between the user equipment and the subject enters a pre-warning region, wherein the pre-warning region is based on at least a first distance;
entering a monitoring mode based on the distance between the user equipment and the subject being less than the first distance, wherein in the monitoring mode the user equipment performs an operation to mitigate degradation of the established connection due to a required power backoff of an antenna of the user equipment;
detecting, by the at least one non-connected antenna device, a moving direction of the subject; and
detecting a condition that the distance between the user equipment and the subject has entered the pre-warning region based on the detected moving direction of the subject.
