Lorsque des symboles de multiplexage par répartition orthogonale de la fréquence (OFDM) pour transmettre différents signaux de liaison montante se chavauchent partiellement, la puissance de transmission sur des symboles de modulation OFDM se chevauchant et des symboles de modulation OFDM ne se chevauchant pas peut être déterminée, afin de garantir que la somme de la puissance de transmission sur chaque symbole de modulation OFDM ne dépasse pas une limite de puissance totale, permettant ainsi d'optimiser la commande de puissance de transmission de liaison montante. Le procédé de communication sans fil comprend les étapes suivantes: un dispositif terminal détermine la puissance de transmission d'un premier signal de liaison montante sur M symboles de modulation OFDM et N symboles de modulation OFDM, les M symboles de modulation OFDM et les N symboles de modulation OFDM étant tous les deux utilisés pour transmettre le premier signal de liaison montante, les M symboles de modulation OFDM étant en outre utilisés pour transmettre un second signal de liaison montante, et M et N étant tous deux des nombres entiers positifs.
