Abstract
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.

A method of distributing a set of data to at least one wireless station, from a radiocommunication network with multicast capabilities, through at least one base station, said distribution being performed to at least one multicast group joined by said at least one wireless station, the method comprising 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.
A radiocommunication network with multicast capabilities, arranged for distributing a set of data to at least one wireless station, through at least one base station, said distribution being performed to at least one multicast group joined by said at least one wireless station, the method comprising 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.
A base station for use in a network with multicast capabilities, arranged for distributing a set of data to at least one wireless station, said distribution being performed by said network to at least one multicast group joined by said at least one wireless station, the base station comprising:
- means for receiving at least one data stream for transmission to at least one respective multicast group;
- and
- means for adapting the transmission rate of at least some of the data streams, depending on an available capacity of said base station.
