An apparatus and method is provided for a cellular radiocommunication using macrodiversity techniques. The method includes the transmission, to a first radio network controller, of a first frame of hard bits from a base node whose accuracy indicator has a so-called "good" level, if at least one accuracy, indicator has the good level, the transmission, to the first radio network controller if no accuracy indicator has the said good level, of each of the first frames of soft bits from at least two base nodes and the combination in the first radio network controller of the transmitted frames of soft bits in order to generate a second frame of hard bits.
