Abstract
modalidades da presente invenção revelam um método de coleta de informações de pré-codificação e um dispositivo de transmissão e se relacionam com o campo de comunicações, de modo a melhorar o desempenho de um sistema de comunicações sem fio. uma solução específica é: pré-codificar, por um lado de transmissão, um primeiro sinal piloto de acordo com uma primeira matriz de pré-codificação, e enviar um primeiro sinal piloto pré-codificado para um lado de recepção, onde a primeira matriz de pré-codificação é a mesma que uma matriz de pré-codificação usada para transmissão de dados atual; pré-codificar, pelo lado de transmissão, n segundos sinais piloto de acordo com n segundas matrizes de pré-codificação, e enviar n segundos sinais piloto pré-codificados para o lado de recepção, em que n é um número inteiro maior ou igual a 1, as segundas matrizes de pré-codificação usadas para a pré-codificação dos segundos sinais piloto são diferentes entre si, e as n segundas matrizes de pré-codificação são diferentes da primeira matriz de pré-codificação; e receber, pelo lado de transmissão, informações de feedback de pré-codificação enviadas pelo lado de recepção. a presente invenção é utilizada em um processo de transmissão de dados.
