ABSTRACT:
The invention concerns a method for coordination of the interference in the uplink between cells (B1,B2) of a single frequency network with the frequency band used for uplink being subdivided into at least two subsets(F1F2. . . FR), whereby a resource related to a dedicated subset is allocated to a mobile terminal (T1) located in a first cell (B1) of said cells in the border area to a neighbor cell (B2-B4), the based station of the cell (B2) with the highest interference damage caused by the mobile terminal (T1) accepts a high interference level on said dedicated subset dependent on network criteria, and the usage of said dedicated subset in the cell (B2) with the highest interference damage caused by the mobile terminal (T1) is restricted under observation of the interference level, a base station, a mobile terminal and a mobile network therefor.
