Abstract

Divers aspects de l'invention concernent, d'une manière générale, la communication sans fil. Selon certains aspects, un dispositif émetteur, tel qu'un équipement utilisateur ou une station de base, peut déterminer, pour une communication à faible latence, qu'un seuil se rapportant à un débit de codage ou à une taille de ressource est satisfait pour une communication. Le dispositif émetteur peut transmettre la communication à l'aide d'un programme de redondance sélectionné au moins après qu'il a été déterminé que le seuil se rapportant au débit de codage ou à la taille de ressource est satisfait pour la communication. L'invention concerne également de nombreux autres aspects.
