Abstract

La présente invention concerne un appareil et un procédé de communication sans fil. Le procédé par un équipement d'utilisateur (UE) comprend les étapes suivantes : recevoir, par l'UE en provenance d'une station de base, une première information et/ou une deuxième information et/ou une troisième information ; et en fonction de la première information et/ou de la deuxième information et/ou de la troisième information, l'UE détermine une ressource de canal de commande de liaison montante physique (PUCCH) correspondant à un indice de ressource de PUCCH (r PUCCH) et détermine un indice de code de couverture orthogonal (OCC) et/ou un indice d'entrelacement pour la ressource de PUCCH. Ceci peut résoudre des problèmes dans l'état de la technique, fournir une détermination de ressource de PUCCH, fournir une bonne performance de communication, et/ou fournir une haute fiabilité.
