1. A method of operating a user equipment (UE) in a wireless communication network, the method comprising:
receiving a plurality of signals from a plurality of nodes, comprising receiving the plurality of signals from at least two nodes of the plurality of nodes, the at least two nodes having a common identifier;
determining a plurality of radio signal strength measurements, each radio signal strength measurement being associated with a signal of the plurality of signals received from the plurality of nodes, comprising determining a subset of the plurality of radio signal strength measurements in which each radio signal strength measurement of the subset of radio signal strength measurements are associated with a signal of the plurality of signals received from the at least two nodes of the plurality of nodes that have the common identifier; and
determining whether there is an indication that a first node of the plurality of nodes may be an imposter node based on the plurality of radio signal strength measurements, comprising comparing different radio signal strength measurements of the plurality of radio signal strength measurements that are associated with the common identifier, comprising:
determining a standard deviation between the different radio signal strength measurements of the plurality of radio signal strength measurements associated with the common identifier; and
determining whether there is an indication that one of the nodes of the plurality of nodes that is associated with the common identifier may be an imposter node based on whether the standard deviation exceeds a threshold value,
wherein the threshold value is calculated based on mobility related data of the UE.
