Method and transmitting device for transmitting data symbols from subscriber signals via a radio interface of a mobile communications system

A transmitting device for transmitting data symbols originating from subscriber signals via a radio interface of a mobile communications system in which N data symbols of a subscriber signal form a block, the transmitting device comprising:

• a control device for dividing the block into a plurality of partial blocks each having Ns data symbols;
• a modulation device for modulating the Ns data symbols of one of the plurality of partial blocks onto a plurality of different subcarriers for simultaneous transmission, a modulation for each of the plurality of the different subcarriers being carried out with at least one individual code symbol, said modulation device also heterodyning the plurality of the different subcarriers to form a broadband carrier;
• and
• a transmission device receiving the plurality of partial blocks from said modulation device and transmitting the plurality of partial blocks via the radio interface.

A base station for transmitting data symbols originating from subscriber signals via a radio interface of a mobile communications system in which N data symbols of a subscriber signal form a block, the base station comprising:

• a transmitting unit, including:
• a control device for dividing the block into a plurality of partial blocks with Ns data symbols;
• a modulation device for modulating the Ns data symbols of one of the plurality of the partial blocks onto a plurality of different subcarriers for simultaneous transmission, a modulation for each of the plurality of the different subcarriers being carried out with at least one individual code symbol, said modulation device also heterodyning the plurality of the different subcarriers to form a broadband carrier;
• and
• a transmission device receiving the plurality of partial blocks from said modulation device and transmitting the plurality of partial blocks via the radio interface.

A mobile station for transmitting data symbols originating from subscriber signals via a radio interface of a mobile communications system in which N data symbols of a subscriber signal form a block, the mobile station comprising:

• a transmitting unit, including:
• a control device for dividing the block into a plurality of partial blocks with Ns data symbols;
• a modulation device for modulating each one of the Ns data symbols of one of the plurality of the partial blocks onto a plurality of different subcarriers for simultaneous transmission, a modulation for each of the plurality of the different subcarriers being carried out with at least one individual code symbol, said modulation device also heterodyning sub-carriers to form a broadband carrier;
• and
• a transmission device receiving the plurality of partial blocks from said modulation device and transmitting the plurality of partial blocks via the radio interface.
