Abstract

L'invention concerne un procédé d'indication de ressources et un dispositif associé, utilisés pour apporter une solution quant à la façon de notifier des ressources de liaison montante et de liaison descendante au cours de périodes dans des systèmes futurs de communication sans fil. Le procédé comporte les étapes suivantes: un terminal reçoit des premières informations d'indication, les premières informations d'indication étant au moins utilisées pour déterminer une zone de liaison montante dans une ou plusieurs premières unités de temps après une première unité de temps dans laquelle est située une transmission des premières informations d'indication; le terminal reçoit des deuxièmes informations d'indication, les deuxièmes informations d'indication étant au moins utilisées pour déterminer une zone de liaison descendante dans une première unité de temps dans laquelle est située une transmission des deuxièmes informations d'indication ou une pluralité de premières unités de temps à partir de la première unité de temps dans laquelle est située la transmission des deuxièmes informations d'indication.
