1. A method by at least one apparatus, the method comprising:
receiving, by the at least one apparatus, at least one radio frequency signal comprising a plurality of sets of measurement based values from at least one respective mobile terminal in a communication network;
obtaining information for radio channel modeling by checking at least one measurement based value of at least one set of the measurement based values of the plurality of sets of the measurement based values based on at least one timing measurement value, where information for radio channel modeling comprises location information indicative which set of the measurement based values of at least two sets of measurement based values of the plurality of sets of measurements based values is associated with a nearer position to a node of the communication network;
checking whether multiple peaks of signal strength measurement values occur in the at least two sets of measurement based values of the plurality of sets of measurement based values, and, if said checking yields a positive result, to check which of said at least two sets of measurement based values is associated with a smallest timing measurement value and assigning said location information to the set of measurement based values associated with the smallest timing measurement value;
performing a radio channel modeling based on the obtained information to generate a radio channel model for at least one node in the communication network, wherein a position associated with the at least one node is determined based on the radio channel model.
