FIELD: radio engineering, communication.
SUBSTANCE: invention relates to radio communication. The technical result is achieved due to that, when determining frequencies used by a relay station in a system for assigning cut-off frequencies, the centre frequencies most susceptible to interference from signals of the relay station are determined in order to avoid assigning corresponding frequencies. In an alternative version, the centre frequency of an adjacent cell which can be affected by interference from the signal of the relay station is changed depending on the location of the relay station and the number of positions in which the probability of interference with the centre frequency of the neighbour cell is high is reduced by establishing a region of cut-off frequencies available for assignment to the relay station, depending on the location of said relay station.
EFFECT: matching interference between cells.
