Abstract: A hybrid combination of analog RF beamforming and digital pre-coding is used to improve signal-to-noise ratio and mitigate interference as between an RF base station and a plurality of wireless receivers within a cell area of the base station. Feedback overhead for beamforming training may be reduced by using indices for identifying the preferred beams of each wireless receiver. Scheduling for channel training may be based on identifying non-colliding ones of the RF beams and assigning these to corresponding wireless receivers which can best use the assigned beams in shared transmission slots.

Abstract: A method for precoded communications includes precoding in a first stage, outgoing data streams with first precoding matrices generated in accordance with instantaneous channel feedback received from receiving devices, wherein a configuration of the instantaneous channel feedback is determined in accordance with statistical channel information and individual of the receiving devices, thereby producing first precoded data streams, precoding in a second stage, the first precoded data streams with second precoding matrices generated in accordance with the statistical channel information associated with the receiving devices, thereby producing second precoded data streams, and transmitting the second precoded data streams to the receiving devices.
