Abstract

La présente invention concerne un procédé de traitement d'informations de contrôle de liaison montante, un point de transmission et un terminal. Dans le procédé de traitement des informations de contrôle de liaison montante, un premier point de transmission peut être utilisé pour déterminer un second point de transmission à ajouter pour le terminal et, ensuite, le premier point de transmission envoie des informations d'instruction au terminal, les informations d'instruction servant à donner des instructions aux informations de contrôle de liaison montante sur le second point de transmission pour effectuer une transmission dans un canal de contrôle physique de liaison montante du second point de transmission. Selon les modes de réalisation de la présente invention, les informations de contrôle de liaison montante du point de transmission, qui fournit au terminal une transmission en liaison descendante, ne doivent pas être transmises au point de transmission qui fournit au terminal une transmission en liaison descendante par le biais d'un chemin entre les deux points de transmission. Mais au contraire, le terminal les transmet directement au point de transmission qui fournit une transmission en liaison descendante au terminal, ce qui réduit un surdébit de transmission et un retard de transmission des informations de contrôle de liaison montante.
