Abstract

modalidades da presente invenção revelam um método de configuração de pré-codificação, dispositivo, e sistema. o método de configuração de pré-codificação inclui: gerar informações de configuração de pré-codificação, em que as informações de configuração de pré-codificação são usadas para configurar uma largura de uma banda de frequência para mesma pré-codificação; e enviar as informações de configuração de pré-codificação. as modalidades da presente invenção adicionalmente fornecem um dispositivo final de transmissão, um dispositivo final de recebimento, e o sistema de configuração de pré-codificação. no método de configuração de pré-codificação fornecido nas modalidades da presente invenção, as informações de configuração de précodificação são geradas e enviadas, de modo que uma extremidade de recebimento possa determinar, com base nas informações de configuração de pré-codificação, a largura da banda de frequência para mesma pré-codificação. na técnica anterior, a largura da banda de frequência para mesma précodificação é determinada com base somente em largura de banda de sistema, enquanto a largura da banda de frequência para mesma pré-codificação pode ser flexivelmente determinada nas soluções técnicas fornecidas nas modalidades da presente invenção, de modo que exigências de um sistema de comunicações sem fio possam ser atendidas em cenários diversificados, e o desempenho de sistema possa ser eficazmente otimizado em diferentes cenários.
