Abstract
Embodiments of the present application provide a beamforming based communications method and apparatus. The method includes: obtaining, by a transmit end, a transmit-end precoding matrix TrBB, a transmit-end intermediate-frequency beamforming matrix TrIF, and a transmit-end radio-frequency-end beamforming matrix TrRF according to feedback information that is from a receive end; acquiring a first data stream, and performing precoding processing on the first data stream according to TrBB, to generate a first analog signal; performing weighting and power amplification processing on the first analog signal according to TrIF, to generate a second analog signal; performing weighting and power amplification processing on the second analog signal according to TrRF, to generate a third analog signal; and determining an antenna array matching the third analog signal, and transmitting the third analog signal to the receive end by using the antenna array matching the third analog signal.
