Abstract:
A method for estimating downlink interference on a selected frequency f.sub.sel, comprising the steps of:identifying plural neighboring cells close to a given cell which have currently been allocated use of the same selected frequency f.sub.sel, each of the identified neighboring cells including a broadcast control channel frequency f.sub.BCCH ;having a mobile station located in the given cell make downlink signal strength measurements on the broadcast control channel frequencies f.sub.BCCH of each one of the neighboring cells identified in the previous step having the same selected frequency f.sub.sel ;processing the signal strength measurements to generate a signal strength histogram for each one of the identified neighboring cells;mathematically deriving an intermediate value from each of the generated signal strength histograms; andsumming the derived intermediate values for the histograms associated with each of the neighboring cells to calculate the estimate of the downlink interference on the selected frequency f.sub.sel.
