Abstract

La présente invention concerne un procédé d'utilisation d'une ressource, et un dispositif de communication. Le procédé comprend les étapes suivantes : un premier dispositif de communication reçoit des informations de commande envoyées par un deuxième dispositif de communication, les informations de commande comprenant un domaine d'indication de valeur de décalage ; le domaine d'indication de valeur de décalage étant utilisé pour indiquer une valeur de décalage cible ; le premier dispositif de communication détermine, selon la valeur de décalage cible, s'il faut utiliser une ressource cible, la ressource cible étant une ressource occupée par le deuxième dispositif de communication. En fonction de la solution technique, le premier dispositif de communication peut déterminer, selon la valeur de décalage cible, s'il est autorisé à occuper la ressource utilisée par le deuxième dispositif de communication si nécessaire. Par conséquent, la solution technique améliore la flexibilité d'occupation de la ressource.
