Abstract

L'invention concerne un procédé de communication sans fil et un terminal. Le procédé comprend : la réception par un premier terminal de données de liaison latérale au moyen d'une pluralité de porteuses, les données de liaison latérale sur la pluralité de porteuses correspondant à N1 canaux de rétroaction de liaison latérale physiques (PSFCH) et de positions dans le domaine temporel des N1 PSFCH en chevauchement ; et selon des premières informations, la détermination par le premier terminal, à partir des N1 PSFCH, de N2 PSFCH à transmettre, N1 et N2 étant des entiers positifs et N2 ≤ N1. Les premières informations comprennent au moins certaines des informations suivantes : des priorités de N1 PSFCH ; le nombre N3 de PSFCH pouvant être transmis simultanément par le premier terminal ; la puissance de transmission maximale P1 de chaque PSFCH transmis par le premier terminal ; ou, la puissance de transmission maximale P2 du premier terminal. Dans les modes de réalisation de la présente demande, un terminal qui agit comme une extrémité de réception doit tenir compte d'au moins un facteur dans la détermination d'un PSFCH qui est réellement transmis et la pris en compte desdits facteurs est utile au terminal pour formuler une solution de transmission de PSFCH raisonnable.
