Abstract: Embodiments of the present disclosure provide a data transmission method and an apparatus. The method mainly includes: forming multiple antennas of a BS (base station) into a cross polarization antenna array, and calculating a weighted matrix of a to-be-transmitted data stream of the BS according to channel information between the BS and an MS (mobile station); performing weighted processing on the to-be-transmitted data stream of the BS according to the weighted matrix, and sending a data stream that has undergone the weighted processing from the BS to the MS. The embodiments of the present disclosure may enhance the demodulation performance because the cross polarization antenna array is adopted at the BS, and certain irrelevancy exists between cross antennas; therefore, the embodiments of the present disclosure may significantly enhance the overall performance of sending the data stream from a BS side to an MS side.

Abstract translation: 本公开的实施例提供了一种数据传输方法和装置。 该方法主要包括：将BS（基站）的多个天线形成为交叉极化天线阵列，并根据BS与MS之间的信道信息计算BS的待传输数据流的加权矩阵（ 移动台）; 对根据加权矩阵的BS的待发送数据流执行加权处理，并且将经过加权处理的数据流从BS发送到MS。 本公开的实施例可以增强解调性能，因为在BS处采用交叉极化天线阵列，并且在交叉天线之间存在某些不相关性; 因此，本公开的实施例可以显着增强从BS侧向MS侧发送数据流的整体性能。
