In cellular radio systems it is a problem to provide service to UE (user equipment) on the cell border. In systems that apply a frequency re-use of one, and OFDM access technology, the uplink direction need be improved. One embodiment of this application relates to a radio base station that is equipped with one or more FFT processor/s in addition to the FFT-processor that is adapted for being adjusted to the timed aligned arrival of signals from UE served by the radio base station. The additional FFT processor/s is adapted for being adjusted to the arrival of one or more signals from UE that are served by other radio base station/s. The radio base station is further adapted to send Fourier processed signal information relating to the UE of the other radio base station/s and thereby assist the other radio base station in signal reception. The application also relates to a method for assisting another radio base station in signal reception, and to a method for receiving assistance from another radio base station in signal reception.
