1.A clear cell dominance area optimisation was performed for interference reduction/elimination. Each cell must have a clear dominance instead of a scattered one as seen in the 2G measurement data.
4.In quality evaluation by degradation rate, UEs are generated in the grid for quality evaluation, and then desired SIR is verified. The process is repeated for the number of times epecified, and then the rate for unsatisfatory cases is calculated to determine the degradation rate of the grid.
