    Abstract: A radio network control method that allows uplink signals transmitted by a mobile station to be received by two or more selected base station radio systems and then combined, thus providing receiver diversity. The method requires measurement of radio link qualities of the OFDM signals passing between mobile station and base station radio system. The method is selectively applied to individual mobile stations and for each mobile station to a selection from the available base station radio systems—the selection being based upon the relative and/or absolute measurements of radio link qualities.
