Abstract
An embodiment method for beam-related information and channel state information feedback includes receiving first analog beamformed reference signals; transmitting a first report indicating a set of selected analog beamformed reference signals and a transmission rank that jointly maximize a first performance criterion for subsequent transmissions by a transmitter that transmitted the first analog beamformed reference signals; receiving second analog beamformed reference signals maximized in accordance with the set of selected analog beamformed reference signals and the transmission rank; and transmitting a second report, in accordance with the second analog beamformed reference signals, indicating a channel quality indicator and a precoding matrix indicator that maximize a second performance criterion for subsequent transmissions by the transmitter that transmitted the first analog beamformed reference signals and the second analog beamformed reference signals.
