The RAN includes a processing hardware configured to carry out a communication method that includes receiving a digital data stream for transmission on a time-frequency resource. The RAN precodes the digital data stream using a digital beamforming stage to render a precoded digital downlink data stream for downlink data stream signal transmission to a user equipment. The digital beamforming stage includes a first precoding stage configured according to a long-term matrix, and a second precoding stage configured according to a short-term matrix. The RAN is further configured to generate a downlink data stream transmission signal to the user equipment in accordance with the precoded digital downlink data stream.
