Abstract

feedback de indicador de matriz de precodificação (pmi) para feedback de informação de estado de canal (csi) tipo ii em operações de múltiplas entradas, múltiplas saídas (mimo) de rádio novo (nr) é discutida. de acordo com vários aspectos, um equipamento de usuário (ue) determina uma pluralidade de componentes de feedback de csi e identifica um conjunto de componentes descartados desses componentes com base em um valor de componente específico de um componente de indicador de matriz de precodificação (pmi). o ue pode então gerar um relatório de csi ajustado por ajustar como os componentes de feedback descartados são tratados. o relatório de csi ajustado resultante pode ser então transmitido para uma estação base em serviço.
