Heuristics for the reduction of complexity in UMTS radio network quality assessment
B. Heideck, A. Draegert, Thomas Kürner · 2003
In this paper a couple of simple expressions for calculating the frequency re-use factor describing the uplink interference situation in WCDMA radio networks are derived. The derivation of these heuristic expressions is based on a series of Monte Carlo simulations performed in a hexagonal network with inhomogeneous traffic distributions. it is shown that only specific areas within each cell of the first two tiers contribute significantly to the uplink interference, which reduces the complexity in the network quality assessment. This information can be used to speed up the evaluation of solutions in automatic planning algorithms.
