Abstract

Des procédés, des systèmes et des dispositifs destinés aux communications sans fil sont décrits. Un équipement utilisateur (UE) peut recevoir un message de commande qui indique un premier motif d'intervalle de mesure pour l'UE, le premier motif d'intervalle de mesure provenant d'un ensemble d'un ou de plusieurs motifs d'intervalle de mesure pour l'UE. L'UE peut ensuite recevoir un message indiquant une adaptation au premier motif d'intervalle de mesure sur la base d'une cible de latence associée au trafic pour l'UE. De plus, l'adaptation peut comprendre un ajustement d'un ou de plusieurs paramètres de fonctionnement d'UE associés au premier intervalle de mesure ou une commutation entre le premier motif d'intervalle de mesure et un second motif d'intervalle de mesure. Ainsi, en réponse au message, l'UE peut fonctionner conformément à l'adaptation au premier motif d'intervalle de mesure pendant une occasion d'intervalle de mesure.
