Abstract

L'invention concerne un ou plusieurs dispositifs, systèmes et/ou procédés permettant de faciliter la transmission d'un rapport d'informations d'état de canal (CSI). Par exemple, un signal comprenant une demande de rapport CSI peut être reçu en provenance d'un nœud sans fil. Un réglage peut être déterminé pour le rapport CSI. Un intervalle de temps pour la transmission du rapport CSI peut être déterminé en fonction du réglage. Le rapport CSI peut être transmis au nœud sans fil au niveau de l'intervalle de temps.
