Abstract

Dans les systèmes de communication avancés 5G et 6G, les services multimodaux deviennent omniprésents. Cependant, les services multimodaux nécessitent des communications à faible latence, et lorsque des paquets sont programmés pour être transmis pendant des durées de mesure de signal de cellule, un retard de planification significatif peut survenir. Des modes de réalisation de la technologie divulguée concernent des procédés et des systèmes de relaxation dynamique de l'exigence de planification dans des périodes qui sont dédiées à des mesures de signal de cellule. Dans un exemple, ceci est obtenu par classification de symboles en tant que types différents et/ou à l'aide d'une granularité plus fine lors de la planification. Dans un autre exemple, un procédé de communication sans fil consiste à déterminer, par un dispositif sans fil sur la base d'une condition, une durée pour effectuer une mesure, la durée comprenant un premier intervalle de temps associé et un second intervalle de temps, à recevoir, en provenance d'un nœud de réseau, une transmission pendant le second intervalle de temps, et à effectuer, pendant le premier intervalle de temps, la mesure.
