The invention concerns a method wherein a radio link control stage processes separately first data units containing information items of a specific type and second data units not containing information items of said type. A control stage for access to the media delivers the first data units through a first dedicated transport channel and the second data units through a second dedicated transport channel. The data units delivered through said dedicated transport channels are supplied to an encoding and multiplexing stage to form at least a train of symbols relative to a dedicated physical channel and supplied to a radio transmission stage. The encoding and multiplexing stage and/or the radio transmission stage ensure greater protection against noise through the first dedicated transport channel than through the second dedicated transport channel.
