The invention proposes a method of distributing a set of data to at least one wireless station (1), from a radiocommunication network (2) with multicast capabilities, through at least one base station (12-13), said distribution being performed to at least one multicast group joined by said at least one wireless station. The method comprises the steps of: forming at least one data stream, by encoding a data source with a rateless erasure code; transmitting, through the at least one base station, the at least one data stream to at least one respective multicast group; and for each base station, adapting the transmission rate of at least some of the data streams, depending on an available capacity of said base station.
