BEAMFORMING METHOD AND DEVICE FOR MASSIVE MIMO SYSTEM

Provided are a beamforming method and device for a massive MIMO system. Specifically, horizontal baseband beamforming processing is performed on S data streams to be transmitted by an antenna array so as to obtain T data streams, vertical digital beamforming processing is performed on the T data streams so as to map the T data streams onto corresponding channels according to a preset rule, and analogue beamforming processing is performed on the data stream on each channel so as to map the data stream on each channel onto a corresponding array element of the antenna array for sending. The present invention has the following advantages compared to the prior art: the benefits of RF beamforming and BB beamforming with FH and antenna restrictions are combined, providing good flexibility for BB algorithm selection and RF beam design, balancing the complexity and performance between BB and RF, and implementing massive MIMO in sub-6GHz.
