Le procédé d'indication de ressources comprend la confirmation d'un intervalle de temps par un dispositif de couche supérieure, ledit intervalle n'étant pas configuré avec un canal HS-PDSCH (High Speed Physical Downlink Shared Channel), à partir des intervalles de temps qui suivent le premier intervalle de temps en liaison montante de la sous-trame. Le dispositif de couche supérieure confirme un identifiant d'intervalle de temps correspondant, conformément à la relation correspondante entre les intervalles de temps et les identifiants d'intervalles de temps. Le dispositif de couche supérieure envoie l'identifiant d'intervalle de temps confirmé à des stations de base et à des terminaux utilisateur, et indique aux stations de base de prendre les informations d'indication de l'intervalle de temps acheminées dans le canal de contrôle partagé pour HS-DSCH (HS-SCCH), l'intervalle de temps correspondant alors à l'identifiant d'intervalle de temps, en tant qu'informations d'indication du premier intervalle de temps de la sous-trame, et indique aux terminaux utilisateur de confirmer si le premier intervalle de temps de la sous-trame est ou non configuré avec HS-PDSCH conformément aux informations d'indication de l'intervalle de temps acheminées dans HS-SSCH, l'intervalle de temps correspondant à l'identifiant d'intervalle de temps. La présente invention concerne la technologie de communication sans fil. La présente invention sert à réaliser des indications en fonction de HS-SSCH, lorsque HS-PDSCH est configuré sur l'intervalle de temps TSO de la sous-trame.
