Abstract

realimentação de canal base em sinais de referência. são descritas técnicas para suportar medição e relatórios sobre canal em um sistema de comunicação sem fio. em um desenho, uma célula transmite um sinal de referência específico de célula (crs) utilizado para estimação de canal e demodulação coerente e um sinal de referência com informações espaciais sobre canal (csi-rs) utilizado para medição de canal e relatórios de realimentação de canal. a célula pode transmitir o csi-rs menos frequentemente que o crs, ou de mais portas de antena que o crs, ou em menos elementos de recurso que o crs ou uma combinação deles. em um desenho, um equipamento de usuário (ue) determina pelo menos uma parte de largura de banda configurada para o ue, com cada parte de largura de banda cobrindo pelo menos uma sub-banda. o ue recebe o crs e o csi-rs da célula, determina informações de realimentação de canal para a pelo menos uma parte de largura de banda com base no csi-rs, envia as informações de realimentação de canal à célula e recebe os dados transmitidos pela célula com base nas informações de realimentação de canal.
