Abstract
The present disclosure provides a hybrid beamforming transmission method and a network device. The hybrid beamforming transmission method includes steps of: determining, by a network device, a digital-domain beamforming weight matrix for a first UE in accordance with a channel measurement result; determining, by the network device, a set of beamforming weight matrices in accordance with the digital-domain beamforming weight matrix, and transmitting a signal to the first UE in an analog beamforming manner; selecting, by the network device, a beamforming weight matrix from the set of beamforming weight matrices in accordance with a measurement result from the first UE, as an analog-domain beamforming weight matrix for the first UE; and performing, by the network device, hybrid beamforming transmission in accordance with the determined digital-domain beamforming weight matrix and the selected analog-domain beamforming weight matrix.
