Abstract

La présente invention concerne un procédé, un appareil, et un système d'indication de canal. Dans le procédé selon l'invention : un dispositif sur le côté réseau détermine un de N canaux de liaison descendante parmi N ressources de canal de liaison descendante attribuées par le dispositif sur le côté réseau à un équipement utilisateur (UE) en tant que première ressource de canal de liaison descendante écoutée par l'UE, N étant un nombre entier positif supérieur ou égal à 2 ; le dispositif sur le côté réseau envoie à l'UE des informations d'indication de canal, qui sont utilisées pour la détermination de la première ressource de canal de liaison descendante et l'écoute du premier canal de liaison descendante par l'UE ; ou bien, les N ressources de canal de liaison descendante pré-attribuées par le dispositif sur le côté réseau à l'équipement d'utilisateur (UE) comprennent des ressources de canal en liaison descendante par défaut, qui sont utilisées pour l'écoute directe des ressources de canal de liaison descendante par défaut par l'UE lorsque le dispositif sur le côté réseau n'envoie pas les informations d'indication de canal. Des modes de réalisation de la présente invention résolvent le problème lié à une occupation excessivement élevée des surdébits de ressources de code de canaux de liaison descendante DPCCH ou F-DPCH lorsqu'un grand nombre d'UE sont en ligne.
