In a method for administering radio resources in a mobile radio cell, which includes a plurality of mobile terminals which are distinguishable by their radio signals, and a base station, the administration of radio resources of a mobile radio cell is improved to such an extent that the available radio resources are utilized more economically. A mobile terminal is requested by the base station to send out a signal, currently present at a receiver of the mobile terminal, which is representative of an interference situation at the location of the mobile terminal. This is sent together with information for estimating the channel between the mobile terminal and the base station so that the base station receives raw data at the location of the mobile terminal, and evaluates the signal received from the mobile terminal and the information for estimating the channel between the mobile terminal and the base station for determining the radio sources forming the basis of the signal and the intensities of at least some of the radio sources. Further, the base station in the mobile radio cell adapts the distribution of the radio resources for improving the interference situation at the location of the mobile terminal.
