A method and apparatus for transmitting uplink acknowledge information (ACK) in a communication system using an orthogonal frequency division multiple access (OFDMA) scheme. The method includes receiving a data bit for the uplink ACK; outputting codewords corresponding to the data bit; performing quadrature phase shift keying (QPSK) modulation on symbols for ACK vector indexes corresponding to the codewords for the received data bit; performing inverse fast Fourier transform (IFFT) on a transmission signal having subcarrier clusters to which the modulated transmission symbols are allocated; and transmitting the IFFT-processed transmission signal.

La présente invention se rapporte à un procédé et un appareil permettant de transmettre des informations d'accusé de réception (ACK) en liaison montante dans un système de communication mettant en oeuvre un mécanisme d'accès multiple par division en fréquences orthogonales (OFDMA). Ce procédé consiste à recevoir un bit de donnée pour l'accusé ACK en liaison montante; à délivrer en sortie des mots codés correspondants à ce bit de donnée; à mettre en oeuvre une modulation par déplacement de phase en quadrature (QOSK) sur des symboles associés à des indices vectoriels ACK correspondant aux mots codés pour le bit de donnée reçu; à effectuer une transformée de Fourrier rapide inverse (IFFT) sur un signal de transmission ayant des groupes de sous-porteuses auxquels sont attribués les symboles de transmission modulés; et à émettre le signal de transmission traité par IFFT.
