Abstract

um método de relatório de estado de canal com base em um sinal de referência de informações de estado de canal (csi-rs) em um sistema de comunicação sem fio, de acordo com uma modalidade da presente invenção, compreende as etapas de: receber uma configuração relacionada ao csi-rs a partir de uma estação-base; calcular uma csi mediante a medição de um csi-rs de acordo com a configuração relacionada ao csi-rs; e transmitir as csi calculadas para a estação-base, em que a configuração relacionada ao csi-rs pode incluir uma configuração csi-rs para uma csi ou uma configuração csi-rs para gerenciamento de feixes (bm).
