Abstract

L'invention concerne un procédé et un dispositif de communication sans fil. Le procédé consiste à : recevoir une signalisation de déclenchement sur un premier intervalle de temps, la signalisation de déclenchement servant à déclencher un dispositif terminal pour qu'il envoie un signal de référence de sondage (SRS) d'un groupe de ressources de SRS ; et déterminer un second intervalle de temps sur la base du premier intervalle de temps et d'au moins l'un des éléments suivants : une pluralité de décalages d'intervalle de temps, un décalage d'intervalle de temps correspondant à un premier état de déclenchement indiqué par la signalisation de déclenchement, ou une plage de domaine temporel qui suit le premier intervalle de temps. Le second intervalle de temps est déterminé au moyen de la pluralité de décalages d'intervalle de temps, du décalage d'intervalle de temps correspondant au premier état de déclenchement indiqué par la signalisation de déclenchement, ou de la plage de domaine temporel qui suit le premier intervalle de temps, ce qui permet d'éviter la fixation du décalage d'intervalle de temps entre la signalisation de déclenchement et la transmission de SRS ; c'est-à-dire qu'il est possible de sélectionner ou de déterminer une position relative entre un intervalle de temps utilisé pour recevoir la signalisation de déclenchement et un intervalle de temps utilisé pour envoyer le SRS, ce qui permet de réduire ainsi la limitation et d'améliorer la flexibilité de système.
