Abstract

Method and arrangement in a base station for providing an input parameter in an algorithm for predicting uplink load in a cell in a wireless communication system. The cell comprises at least one user equipment. The method comprises obtaining SIR target value associated with the user equipment, measuring SIR value on a signal sent from the user equipment, comparing the difference between the obtained SIR target value and the measured SIR value with a threshold limit value, selecting the SIR value as input parameter in the uplink load prediction algorithm for the user equipment, if the difference between the obtained SIR target value and the measured SIR value is bigger than the threshold limit value. Otherwise selecting the SIR target value as input parameter in the uplink load prediction algorithm for the user equipment.
