Brief description of the planning of channels frequency to a system of communication network has a narrow band

摘要

The present invention relates to a process for the planning of carrier frequencies implemented in a device for a mobile radio system with a narrow bandwidth shared with a radio communication system, a wide band, of the cells, each comprising a base station to a narrow band and a base station a wide band, and the same band of frequencies, the band of frequencies being partly divided into a given number of blocks frequency, each comprising a given number of carrier frequencies. The device comprises a means (ua) in order to associate the carrier frequencies to the base stations to a narrow band and a means (a) in order to distribute over the frequency band from the carrier frequencies associated with the base stations to narrow band frequency such that each block comprises at least two groups of carrier frequencies separate each associated with a base station, the two groups being selected according to a distribution such that the interference frequency relating to the emission of the base stations associated with groups distributed in a single block has a surface serving interfered cell minimum frequency.
