Abstract

L'invention concerne des procédés, des systèmes et des dispositifs destinés aux communications sans fil. Un équipement utilisateur (UE) peut déterminer un premier ensemble de ressources destinées à être utilisées par l'UE pour effectuer un premier type de mesures d'interférence (par exemple, des mesures de RSSI), et peut effectuer le premier type de mesures d'interférence pour des signaux reçus dans le premier ensemble de ressources. L'UE peut transmettre, à une station de base d'après un résultat de réalisation du premier type de mesures d'interférence, une demande de configuration permettant d'effectuer des mesures d'interférence inter-liaisons (CLI). L'UE peut recevoir la configuration comprenant une indication d'un second ensemble de ressources destinées à être utilisées par l'UE pour effectuer les mesures CLI d'un ou de plusieurs UE agresseurs en réponse à la demande. L'UE peut ensuite effectuer les mesures CLI sur les signaux reçus dans le second ensemble de ressources.
