Abstract

A communication device for RF-based communication with another communication device comprises digital beamforming circuitry configured to perform digital beamforming based on digital beamforming information to obtain RF data streams, and analog beamforming circuitry configured to perform analog beamforming for the obtained RF data streams. The analog beamforming circuitry is configured to perform analog beamforming training with the other communication device enabling the other communication device to compute the digital beamforming information corresponding to one or more combinations of analog beams used in said analog beamforming training. The digital beamforming circuitry is configured to receive the computed digital beamforming information and to use it for performing the digital beamforming.
