Abstract: Scalable channel state information feedback for FD-MIMO involves quantizing the downlink channel according to a finite set of basis vectors to reduce the number of coefficients quantized and reported from a user equipment to a base station. The procedure includes measurement at the base station of angle of arrival spread for uplink signal reception from the user equipment and signaling that spread to the user equipment. The user equipment then quantizes the MIMO channel according to a sub-scheme configured based upon the signaled spread and reports (feeds back) the quantized channel to the base station.

Abstract: A hybrid MIMO system comprises N digital transceiver chains and N analog beamformers, each coupled to one of the digital transceiver chains and comprising M analog transmitter (TX) chains and M analog receiver (RX) chains. One of the analog RX chains is an RX reference node and one of the analog TX chains is a TX reference node. A processor is coupled to a calibration transceiver, the transceiver chains, and the beamformers. For each beamformer the processor measures, using the corresponding transceiver chain and the calibration transceiver, TX and RX phase responses and TX and RX magnitude responses of the TX and RX reference nodes, respectively, determines a reciprocity calibration based on a phase difference between the TX and RX phase responses and a magnitude difference between the TX and RX magnitude responses, and applies the reciprocity calibration to stored beam definitions to correct for the phase and magnitude differences.
