Frequency plans (FPs) based on mobile measurements present several advantages compared to those based on propagation predictions. These FPs use interference matrices (IMs) created from measurement reports (MMRs). MMRs, as described in the GSM specifications, present some limitations: quantization and truncation of measured values, only six strongest neighbours reported and BSIC (base station identity code) decoding procedure. In addition, different types of IMs, depending on the processing of the raw data, can be considered. In this paper, MMRs limitations and their impact on different types of IMs are analyzed. Simulations for macrocell and microcell scenarios have been carried out to reinforce the conclusions.
