The object is achieved by providing a transmission apparatus with: assignment means configured to assign, to each user, one of a frequency block that is obtained by dividing a system bandwidth into each block of continuous frequency subcarriers and a distributed type frequency block that include a frequency subcarrier that is discretely distributed in the system bandwidth; and mapping means configured to assign transmission data to one of the frequency block and the distributed type frequency block according to the assignment.
Le dispositif de transmission selon l~invention comporte un moyen affectant soit un bloc de fréquences pour diviser une bande passante système en blocs continus de sous-porteuses de fréquence pour des utilisateurs respectifs, soit un bloc de fréquences de type distribution composé de sous-porteuses de fréquence distribuées de façon discrète dans la bande passante de fréquences système, et un moyen de mappage pour affecter des données à transmettre soit au bloc de fréquences soit au bloc de fréquences distribuées en réaction à l~affectation.
