Abstract: front page image
(EN)A method and base station for data transmission are disclosed by the present invention. The method includes: sequencing the multiple users which transmit the data; generating channel matrices corresponding to the sequenced multiple users; decomposing the channel matrices to obtain pre-coding coefficients for the data transmission; and coding the data of the multiple users according to the pre-coding coefficients and then transmitting the coded data. According to the present invention, the performance of data reception and the channel capacity are improved.
(FR)La présente invention porte sur un procédé et une station de base pour une transmission de données. Le procédé comprend : le séquencement de multiples utilisateurs qui transmettent les données; la génération de matrices de canal correspondant aux multiples utilisateurs séquencés; la décomposition des matrices de canal pour obtenir des coefficients de précodage pour la transmission de données; et le codage des données des multiples utilisateurs selon les coefficients de précodage, puis la transmission des données codées. Selon la présente invention, les performances de réception de données et la capacité de canal sont améliorées.
(ZH)本发明公开了一种数据发送方法及基站,该方法包括:为发送数据的多个用户进行排序;生成对应于排序后的多个用户的信道矩阵;对信道矩阵进行分解得到数据发送的预编码系数;根据预编码系数将多个用户的数据编码,并发送编码后的数据。通过本发明,提高了数据的接收性能及信道容量。
