Abstract

um aparelho e método e sistema de transmissão de informação de canal são expostos, para melhoria da precisão do retorno da informação de canal. um primeiro dispositivo inclui: um módulo de recepção (1101), configurado para o recebimento de um sinal de referência a partir de um segundo dispositivo; um módulo de processamento (1102), configurado para a obtenção de uma matriz de pré-codificação com base no sinal de referência, e a geração de uma primeira informação de canal e uma segunda informação de canal que são usadas para indicação da matriz de pré-codificação; e um módulo de envio (1103), configurado para o envio da primeira informação de canal e da segunda informação de canal para o segundo dispositivo. a precisão da primeira informação de canal é mais alta do que a precisão da segunda informação de canal. a primeira informação de canal inclui uma informação de fase de cada elemento na matriz de pré-codificação, e a segunda informação de canal inclui uma informação de amplitude de cada elemento na matriz de pré-codificação. a precisão de informação de fase da matriz de pré-codificação, que é relativamente crucial para a restauração de uma matriz de canal e que requer alta precisão, é mais alta do que a precisão da informação de amplitude. por um lado, os tempos de processamento de retorno de informação de canal podem ser reduzidos; por outro lado, a precisão de retorno de informação de canal pode ser assegurada.
