A mixed-cell propagation model for interference prediction in a UMTS network

With the support of mixed cells and hierarchical cell structures in UMTS, propagation information (coverage and interference) between different cell types is required. A mixed-cell propagation model is presented which is suitable for predicting interference in mixed macrocellular and microcellular environments. The main features of the model are described together with examples of interference prediction including C/I and most-likely-server plots. Comparisons between model predictions and measurements for a mixed cell environment are also presented
