Abstract
as operações de informações de estado de canais (csi) são reveladas em relação a operações de conformação de feixe de elevação (eb) /múltiplas entradas e múltiplas saídas de dimensão completa (fd)(ed/fd-mimo). com o processamento de csi associado a múltiplos recursos de csi-sinal de referência (csi-rs), podem surgir ambiguidades na determinação do tipo e classificação de relatórios de csi. o tipo de relatório de csi pode ser determinado com o uso de um último indicador de seleção de feixe relatado (bi) ou, na ausência de um bi, pode ser determinado de acordo com uma regra predefinida. quando a classificação e o bi forem relatados separadamente e a classificação estiver ausente, o equipamento de usuário pode determinar uma classificação de referência padrão para o relatório de csi com base em cada ou tanto na classificação anteriormente relatada como em bi. quando a classificação e o bi forem relatados em conjunto, os esquemas de codificação com larguras de bit fixas determinadas com base em processos ou recursos de csi-rs podem ser usados para aprimorar a decodificação. portas, processos ou recursos da antena de csi-rs também podem ser usados na determinação da aplicação de relaxamento de processamento de csi.
