WEIGHT OBTAINING METHOD AND APPARATUS FOR DUAL-CURRENT MULTIPLE INPUT MULTIPLE OUTPUT BEAMFORMING, DATA TRANSMISSION METHOD AND APPARATUS FOR DUAL-CURRENT MULTIPLE INPUT MULTIPLE OUTPUT BEAMFORMING

摘要

The present invention provides a weight obtaining method for dual-current multiple input multiple output (MIMO) beamforming, which is applied in a wireless communication system including a transmitting end and a receiving end. The antenna arrays of the transmitting end includes two antenna subarrays. Each antenna subarray forms a wave beam. The method for obtaining the beamforming weight of each antenna subarray includes: obtaining channel information from transmitting antennae of each antenna subarray to receiving antennae of the receiving end; determining the beamforming weight of the antenna subarray according to the channel information. The present invention also provides a weight obtaining apparatus for dual-current MIMO beamforming, and a data transmission method and a data transmission apparatus for dual-current MIMO beamforming.
