<p>The invention relates to frequency planning in a cellular communication system, such as a GSM cellular communication system. An apparatus for frequency planning comprises an interference matrix processor (201) which generates an interference matrix comprising interference relationships between different cells. For example, carrier to interference or interference penalty values for cell pairs can be determined. An interference matrix limiter (203) limits the number of interference relationships to a first number, N, of highest interference relationships for each cell. The first number N can be determined in response to the re-use pattern and number of frequencies available for the frequency plan. A frequency plan processor (205) then proceeds to perform a frequency planning using the interference matrix.</p> |
