Improving cell assignment probabilities using CPICH quality

In this paper the method for determining cell assignment probabilities, used for cellular network planning, is extended to take cell breathing into account. The model will be changed from a model based on the pilot power to a model based on the quality of the pilot signal. To reach a usable expressions some simplifications are made that hold in the network scenario, given by a network where the load is randomly spread and the investigated pixel is located randomly within the cell. In that case the ratio between the single cell state and the soft handover state is constant for load, which gives a simple cell assignment probability formulation that meets the requirements.
