Abstract

são descritos métodos e aparelhos para a realimentação da informação de estado do canal (csi) em uma rede sem fio. em uma modalidade, um método inclui receber a sinalização que inclui uma primeira configuração do sinal de referência (rs) csi com potência não zero (nzp) para medição do canal; uma segunda configuração do nzp csi-rs; e uma configuração de medição de interferência da csi (csi-im) para medição de interferência. o método inclui receber uma solicitação de realimentação da csi e estimar a csi com base pelo menos na primeira configuração do nzp csi-rs sinalizada, na segunda configuração do nzp csi-rs, e na configuração da csi-im.
